Answer:
Step-by-step explanation: The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y).

The table shows the cost of a sandwich and a drink at a local cafeteria. how much more does a sandwich cost than a drink
Answer:
$2.02
Step-by-step explanation:
1.50/2 = 0.75
0.75 - 0.49 = 0.26
Sandwich = 2(0.75)+1.5 = 3
Drink = (0.49) + 0.49 = 0.98
3 - 0.98 = 2.02

Answer:
Heyy mate..!Step-by-step explanation:
ᴛʜᴇ sʟᴏᴘᴇ=2/3ᴛʜᴇ ʏ ɪɴᴛᴇʀᴄᴇᴘᴛ= -1Reason 1. M∠A + m∠B + m∠C = 1. 2. 28° + x − 4° + = 180° 2. Substitution 3. X = 3. Algebra
Answer:
156°
Step-by-step explanation:
Reason 1.
M∠A + m∠B + m∠C = 1.
2.
28° + x − 4° + = 180°
We collect like terms
x = 180° + 4° - 28°
x = 156°

Which of the following complex numbers is
equivalent to (3-1) 27 (Note: 1==1)
A)..8.-..6i.
2-2ab+be
0
B) 8+ 6i
(-)
C) 10 - 6i
9 -6 (-i) +-
D-10 +61
Answer:
[tex]8-6i[/tex]
Step-by-step explanation:
Multiply out [tex](3-i)^2[/tex] in order to find out which expression it is equivalent to.
1) Since the whole quantity is squared, write it out as [tex](3-i)(3-i)[/tex].
[tex](3-i)^2\\(3-i)(3-i)[/tex]
2) Multiply binomials by using the FOIL method. Multiply the terms that are listed first in each binomial, then the ones that are listed outermost when looking at both binomials, then innermost, and finally the last terms listed in each binomial. Simplify and combine like terms.
[tex](3-i)(3-i)\\9 - 3i - 3i + i^2[/tex]
[tex]9 - 6i + i^2[/tex]
3) [tex]i = \sqrt{-1}[/tex], so [tex]i ^2[/tex] must be [tex](\sqrt{-1} )(\sqrt{-1})[/tex]. Thus, [tex]i^2[/tex] is equivalent to -1. Knowing this, simplify and combine like terms.
[tex]9 - 6i + ((-\sqrt{1} )(\sqrt{-1} ))[/tex]
[tex]9 - 6i -1\\8 - 6i[/tex]
Thus, it is equivalent to [tex]8 - 6i[/tex] .

5x-3-2x=18-4x Please Explain
Answer:
x = 3 i promise that's the right answer
Step-by-step explanation:
Answer:
x=3
Step-by-step explanation:
Step #1. Simplify what you've been given
5x-3-2x=18-4x
5x-2x=3x
3x-3=18-4x
Step #2. Add 4x to both sides
3x+4x-3=18
7x-3=18
Step #3. Add 3 to both sides
7x=18+3
7x=21
Step #4. Divide both sides by 7
x=21/7
x=3

Q11 - 12 sidesQ12 - 10 sidesStep-by-step explanation:
Use the formula for sum of interior angles of a regular polygon:
S = 180(n - 2)Each angle A measures:
S/n = 180(n - 2)/nA = 180(n - 2)nAn = 180n - 360(180 - A)n = 360n = 360/(180 - A)Question 11Each angle is 150, then finding n:
n = 360/(180 - 150)n = 360/30n = 12Question 12Each angle is 144, find n:
n = 360/(180 - 144)n = 360/36n = 10Answer:

Perry's school is due west of his house and due south of his friend Sasha's house. The
distance between the school and Sasha's house is 6 miles and the straight-line distance
between Perry's house and Sasha's house is 10 miles. How far is Perry's house from school?
Answer:
8 miles
Step-by-step explanation:
You can think of it as a triangle, which will look like the picture at the bottom.
You're trying to find the missing length, and to do that you can use the Pythagorean theorem.
That would be:
[tex]6^{2} + x^{2} =10^{2}[/tex]
Then, solving:
[tex]36 + x^{2} =100\\x^{2} = 64\\x = 8[/tex]
Therefore, the answer is 8 miles

A recycle center received 7.2 tons of glass, 8,500 pounds of paper, and 5/8 ton of aluminum. If 2,000 pounds = 1 ton, approximately what was the total amount of recyclable material received at the center?
Answer:
7.2 X 2000 = 14400 pounds
5/8 = 0.625, 0.625 X 2000 = 1250 pounds
14400 + 1250 + 8500 = 24150 pounds
24150/2000 = 12.08 tons

2: A bag contains 5 black counters, 4 blue counters, and
1 white counter. A counter is taken from the bag at
random. Write down the probability that the counter
was blue.
Answer:
The probability that the counter was blue is [tex]\mathbf{\frac{2}{5}}[/tex]
Step-by-step explanation:
Number of black Counters = 5
Number of blue Counters = 4
Number of white Counters = 1
We need to write down the probability that the counter was blue.
First find Total Counters
Total Counters = Number of black Counters + Number of blue Counters + Number of white Counters
Total Counters = 5+4+1
Total Counters = 10
Now, we need to find probability that the counter taken was blue
The formula used is:
[tex]Probability= \frac{Number\:of\:favourable\:outcomes}{Total\:outcomes}[/tex]
There are 4 blue counters in the back, so Favourable outcomes = 4
[tex]Probability= \frac{Number\:of\:favourable\:outcomes}{Total\:outcomes}\\Probability= \frac{4}{10}\\Probability= \frac{2}{5}[/tex]
The probability that the counter was blue is [tex]\mathbf{\frac{2}{5}}[/tex]

Solve 12(x - 2) + 3x = {(x + 12) + 10x
Answer:
x=9
Let's solve your equation step-by-step
12(x−2)+3x=x+12+10x
Step 1: Simplify both sides of the equation.
12(x−2)+3x=x+12+10x
(12)(x)+(12)(−2)+3x=x+12+10x(Distribute)
12x+−24+3x=x+12+10x
(12x+3x)+(−24)=(x+10x)+(12)(Combine Like Terms)
15x+−24=11x+12
15x−24=11x+12
Step 2: Subtract 11x from both sides.
15x−24−11x=11x+12−11x
4x−24=12
Step 3: Add 24 to both sides.
4x−24+24=12+24
4x=36
Step 4: Divide both sides by 4.
4x/4=36/4
x=9
Answer:
x=9
Answer: x = 9
Step-by-step explanation:
12(x − 2) + 3x = x + 12 + 10x
12(x - 2) + 3x = 11x + 12
12x - 24 + 3x = 11x + 12
15x - 24 = 11x + 12
15x = 11x + 12 + 24
15x = 11x + 36
15x - 11x = 36
4x = 36
x = 36/4
x = 9

[tex] \frac{24x {}^{2} }{5xy} [/tex]
hurry
Answer:
24x / 5y
Step-by-step explanation:
Given :
24x² / 5xy
24x² = 24 * x * x
5xy = 5 * x * y
Hence,
24x² / 5xy = (24 * x * x) / (5 * x * y)
= (24 * x) / (5 * y)
= 24x / 5y
Bob's dog needs medication. He told the veterinarian that the dog weighs 30lbs . The medicine is measured as 16mg for each kilogram of the animal's mass. How much medicine should be given to Bob's dog?
Use 1lb=0.45 kg and do not round any computations.
Answer:
Bob's dog should be given 216 mg of medicine.
Step-by-step explanation:
Given that:
Weight of dog = 30 lbs
We know that:
1 lb = 0.45 kg
30 lbs = 0.45 * 30 kg
30 lbs = 13.5 kg
Medicine for each kilogram of weight = 16 mg
1 kilogram = 16 mg
13.5 kg = 16 * 13.5 mg
13.5 kg = 216 mg
Hence,
Bob's dog should be given 216 mg of medicine.

HELP I NEED HELP FAST!!!!
PLEASE ANSWER:)
Answer:
y = -5x - 5
Step-by-step explanation:
to get the coefficient of the 'x' term (which is the slope) you take the difference of the y-values [5 - (-5)] divided by the difference of the x-values (-2 - 0)
so slope = 10/-2 or -5/1
to get the -5, this is the point at which the line intersects the y-axis; from looking at the graph you can see this is -5

Luciahas$40,000inasavingsaccountthatearns14%annually.Theinterestisnotcompounded.Howmuchinterestwillsheearnin4years? Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years. $
Answer:
$22,400.
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 14%/100 = 0.14 per year,
then, solving our equation
I = 40000 × 0.14 × 4 = 22400
I = $ 22,400.00
The simple interest accumulated
on a principal of $ 40,000.00
at a rate of 14% per year
for 4 years is $ 22,400.00.
