Solve the system of equations by inspection. Explain your reasoning
-2x + 4y = 5
-2y + 4y = 6
PLEASE HELP ♡
Answer & step-by-step explanation:
Assuming the second equation is a typo and it's -2x+4y=6
No solutions. The quantity on the LHS is the same on both equation. You're basically required to find something that is at the same time equal to 5 and 6. Which is obviously impossible.

Answer:
To find percent change, we do: ( new-old / old ) * 100
So,
30 is old, 15 is new.
15 - 30 / 30
= -15 / 30 = -1/2 (100) = -50%
Answer:
15
Step-by-step explanation:
because 30 -15 = 15

What is problem-solving?Problem-solving is the act of defining a problem; figuring out the purpose of the trouble; identifying, prioritizing, and selecting alternatives for an answer; and imposing an answer.
Problem-solving starts with identifying the issue. As an example, a trainer may need to parent out a way to improve a scholar's overall performance on a writing talent test. To do that, the instructor will overview the writing exams looking for regions for improvement.

During the summer, Cecile read twice as many books as Kami. Laura read three times as
many books as Kami. Gigi read the same number of books as Cecile, Laura, and Kami
combined. Gigi read 30 books. Write and solve an equation to find the number of books
each girl read.
Answer:
The equation
c x 2 > k
l x 3 ?> c > k
g = 30 = c + l + k
this equation is the same as...
Cecile read twice as many books as Kami.
Laura read 3 times as many books as Kami, but possibly less than Cecile.
Gigi read 30 books. 30 books is the same as all 3 girls combined.
To find out how many books each girl read, you need to find 3 unequal numbers that add up to 30. These numbers are substituted, only because they can be anything at all, and I want to prevent confusions.

Math of Finance: Chapter 2 Test
When we left James, he had decided to take a job at Jimmy John's as a sandwich artist with an expected salary of
$31,200 per year. James is really looking forward to the pay increase to help take care of his wife and two kids
After working four weeks, he gets his first check. It is much less than he expected. It turns out he will only get paid
for two weeks because Jimmy John's has a delayed paying process. Everyone gets paid two weeks after they work to
give Human Resources time to prepare the tax information. Since James gets paid every two weeks, a)what is his
gross income for his checks? His pay was much less. It tums out, other people get his money first. He had to pay
Federal Income Tax. b)Use the chart on the back of the test to determine his FIT. He also has to pay State
Income Tax. Oklahoma has a flat 5% tax. c)What is his SIT at 5% of his paycheck? Also, something called FICA
was on his paystub. His employer told him it was a required 6.2% tax for Social Security Retirement and a 1.45%
tax for Medicare when he gets older. d)Find James' Social Security Tax. e)Find his Medicare Tax. What is the
amount of FICA Tax listed as being withheld(add together)? Next came the big schock. Apparently, the
Republican Party still hasn't ended required healthcare. Because of this, James has to pay for group insurance with
Jimmy John's. It is $100 every paycheck, g)what percent of James' gross income is this each month? Finally,
James looks at the other category. It has two deductions listed. First, it has Sandwich Union Body Dues. Annual
dues are $130. h)How much was taken out for SUB dues just this paycheck? The second charged deduction for
other was IRA Retirement. He remembers signing up because Jimmy Johns' offers a matching 5%. If James' is
maximizing the match, i)how much is being taken out for retirement from his paycheck? After going over all the
numbers with his boss, it looks like James' check is correct. j)How much was his net income? If these numbers
remain consistent through the year, k)how much will James bring home for the year? DWhat percent of his
expected salary is this? James was really looking forward to his big paycheck. He thought he would have enough
money to get a loan on a new car. m)Do you think he should try to get the loan or not? n>Explain your opinion.

Which statement best describes the acceleration of the box?
A) The box accelerates at 1.0 m/s squared to the right because the net force is 17N to the right
B) The box accelerates at 1.9 m/s squared to the right because the greater force is to the right 9
The box accelerates at 3.0 m/s squared because the combined forces cause the box to accelerate
D) The box does not accelerate, because neither force is large enough to move the box

Step-by-step explanation:
Calculate the volume of a right cylinder with a base area of 21.23 cenitimeters and
a height of 3.2 centimeters to the nearest hundredth of a centimeters).
Answer: 67.94 cm^2
Step-by-step explanation:
The volume of a cylinder equals the base area multiplied by the height.
Therefore, the volume would be equal to 21.23cm*3.2cm = 67.936 cm^2
Rounded to the nearest hunderedth, the volume would be 67.94 cm^2
2) Lucas has saved $50. He earns
$18.00 per hour at his job. He plans to
buy ticket to go on a cruise for $2300.
Write the minimum number of hours
Lucas must work to buy the ticket.
Answer:
125 hours
Step-by-step explanation:
Lucas already has $50. Since he get $18 per hour, you should use that to get the answer. After a little while, I got 125×18 and got 2250. If you add up the $50 he already has, the minimum hours he has to work is 125 hours which is about 5 days.
Answer:
I think the answer is 125 hours
Step-by-step explanation:
To find the unit rate we divide $2300 divided by $18.00
$2300 ÷ 18 = 127.777778
We round that up to 128
We also need to find the unit rate of his saved money
$50 ÷ $18.00 = 2.77777777778
We round that up to 3
128 hours - 3 hours = 125 hours
Fiona is x years old thomas is 3 years older than fiona cara is twice as old as fiona the sum of their ages is 51
The ages of Fiona, Cara and Thomas is 17, 34 and 20 respectively.
What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Fiona who is [x] years old. Thomas is 3 years older than Fiona. Cara is twice as old as Fiona the sum of their ages is 51.
We can write -
Age of Thomas = [y] = x + 3
Age of Cara = [z] = 2x
and
2x + x = 51
3x = 51
x = 17
Age of Thomas = [y] = x + 3 = 20
Age of Cara = [z] = 2x = 34
Therefore, the ages of Fiona, Cara and Thomas is 17, 34 and 20 respectively.

JKLM is a triangle. Find the measure of angle KL and JM
Answer:
x = 10
m∠K = 90°
y = 15
JM = 65
Step-by-step explanation:
KJ = LM
⇒ x + 31 = 5x - 9
⇒ 40 = 4x
⇒ x = 10
From inspection of the diagram, m∠K = 90° (right angle)
KL = JM
⇒ 4y + 5 = 2y + 35
⇒ 2y = 30
⇒ y = 15
JM = 2y + 35
⇒ JM = 2(15) + 35
⇒ JM = 30 + 35
⇒ JM = 65

The equation for finding the circumference of a circle is 2pi times the radius.
The radius is already given, so we multiply it by 2.
12*2
= 24
After that, we multiply 24 by pi.
24*3.14
= 75.36

Triangle IJK is similar to triangle LMN. Find the measure of side LM. Round your answer to the nearest tenth if necessary.
Answer:
It's either 39.2 or 39.3 (a more accurate answer) because it depends on what you round by. since it's Delta Math, you should get 2 attempts.
Step-by-step explanation:
Since they are similar, they are proportional.
54/11=4.90909091 or 4.9
Multiply 11 by 4.90909091 and you get 54
Multiply 8 by 4.90909091 and you get 39.3
if you multiply by 4.9 you get 39.2

Answer:
(4/7 , 1 4/7)
Step-by-step explanation:
Answer:
[tex]\sf (-\dfrac{4}{7} ,1\dfrac{4}{7} )[/tex]
given:
y = 6x+5y = -x+1insert question 2 into 1
[tex]\sf -x + 1 = 6x + 5[/tex]
[tex]\sf -x - 6x = 5 - 1[/tex]
[tex]\sf -7x = 4[/tex]
[tex]\sf x = -\frac{4}{7}[/tex]
find the value of y:
[tex]\sf y = -x + 1[/tex]
[tex]\sf y = -\frac{-4}{7} + 1[/tex]
[tex]\sf y = \frac{4}{7} + 1[/tex]
[tex]\sf y = \frac{4}{7} +\frac{7}{7}[/tex]
[tex]\sf y = \frac{11}{7}[/tex]
[tex]\sf y = 1\frac{4}{7}[/tex]
Therefore coordinates: (x,y) = [tex]\sf (-\dfrac{4}{7} ,1\dfrac{4}{7} )[/tex]
