Answer:
The value of a that can substituted into equation D = 4b + 5
Step-by-step explanation:
Given that:
a = 4b + 5 ---- (equation c)
a = 6b - 2 ---- (equation d)
Replace the value of a = 4b + 5 into "a" in (equation d) to solve the system of equations.
So;
4b + 5 = 6b -2
5 + 2 = 6b -4b
7 = 2b
b = 7/2
b = 3.5
Answer:
The correct answer is 4b + 5 ( A )

Answer: 15.199
Step-by-step explanation:
Using the Pythagorean theorem, we know that a²+b²=c²
In this case, we know that c is 16, and that b is 5.
We can rearrange the equation so that it becomes a²=c²-b²
a²=16²-5²
a²=256-25
a²=231
√a²=√231
a=15.199

Which ratio is not equivalent to 2 : 7? Please help I need the answer now!!
Answer:
20 : 65
Step-by-step explanation:
2 x 4 = 6
7 x 4 = 28
2 x 7 = 14
7 x 7 = 49
2 x 11 = 22
7 x 11 = 77
2 x 10 = 20
7 x 10 = 70 not 65
Answer:
C - 20:65
Step-by-step explanation:
7 can't even divide into 65.
question is in picture
Answer:
C. 60%
Step-by-step explanation:
Consider 1st row of table
Total Price = P= 22.50
Discount=D=13.50
Percent discount=(D/P) x 100
=(13.5/22.5) x 100
= 60%
Consider 2nd row of table
Total Price = P= 27
Discount=D=16.20
Percent discount=(D/P) x 100
=(16.2/27) x 100
= 60%
Now we know discount rate is r=60%

Have a nice day.
I'm not smart and I stink at math so can someone plz help me 12/x = 8
1. We need to get rid of all the denominator in this equation.
This can be done by multiplying left and right sides by the LCD.In the problem: 12/x = 8, the LCD is X.12/x = 8 is now 12 = x * 8
1a. 8 * x = 8x
Now, your answer is 3/2, but It's improper. Let's convert it into a mixed number.
Subtract 3 by 2.
3 - 2 = 1
3/2 = 1 1/2
Therefore, your answer is 1 1/2. Also, the answer is 1.5.

Answer:
x=65
Step-by-step explanation:
Step 1: Add -3 to both sides.
√x−1+3+−3=11+−3
√x−1=8
Step 2: Solve Square Root.
√x−1=8
x−1=82(Square both sides)
x−1=64
x−1+1=64+1(Add 1 to both sides)
x=65

Sue bought 2 pairs of jeans and a belt that cost $6.95. The tax on the items was $5.85. Sue paid the cashier $70.00. How much money did Sue receive in change? Write you answer in a complete sentence.
Answer: Sue's change will be $57.20
Step-by-step explanation:
Sue bought 2 pairs of jeans and a belt for $6.95.
Sue also paid a tax of $5.85 for the items.
Sue gave the cashier $70, her change will therefore be:
= 70 - 6.95 - 5.85
= $57.20

Which of the following functions represents f(n), the number of small squares in figure n?
a.f(n)=4n^2+2
b.f(n)=n^2+5
c.f(n)=(n+1)^2+2
d.f(n)=(n+1) (n+2)
Answer:
c. f(n) = (n+1)^2 + 2
Step-by-step explanation:
It is c. because...
f(n) = (1+1)^2 + 2
2^2 + 2
4 + 2 = 6 (first term)
f(n) = (2+1)^2 + 2
3^2 + 2
9 + 2 = 11 (second term)
f(n) = (3+1)^2 + 2
4^2 + 2
16 + 2 = 18 (third term)
5. Mississippi and Georgia have a total of 21 electoral votes. Mississippi has 6 electoral votes. Use mental math or the guess, check, and revise strategy to solve the equation 6 + g = 21 to find g, the number of electoral votes Georgia has.
Answer: g = 15 . Georgia has 15 electoral votes.
Step-by-step explanation:
Mental math: How many do I need to make up the difference?
counting by 5s: 5, 10 15, 20.
6 is one more than 5.
From 5, three more 5's gets us close to 20. It works.
6 + 15 = 21
Given that p varies jointly as q and r, and p = 7. when q = 2
and r= 1.5, find the following:
a. an equation relating p, q, and r
b. p when q = 4 and r= 6
c. p when p=1 and r=3
d. r when p= 5 and q = 8
Answer:
P = k*q*r
Step-by-step explanation:
P = kqr
7 = k*2*1.5
7 = 3k
k = 7/3
b. P = kqr
= 7/3*4*6
= (7*4*6)/3
= 168/3
= 56
P = 56
c. P = kqr
1 = 7/3*q*3
1 = (7*q*3)/3
1 = 21q/3
Cross product
1*3 = 21q
3 = 21q
q = 3/21
= 1/7
q = 1/7
d. P = kqr
5 = 7/3*8*r
5 = (7*8*r)/3
5*3 = 56r
15 = 56r
r = 15/56
Simplify 9xºy-3 Write your answer using only positive exponents.
Answer:
we conclude that:
[tex]\:9x^0y^{-3}=\frac{9}{y^3}[/tex]
Step-by-step explanation:
Given the expression
[tex]9x^0y^{-3}[/tex]
Apply exponent rule: [tex]a^{-b}=\frac{1}{a^b}[/tex]
[tex]\:9x^0y^{-3}=9\cdot \:\frac{1}{y^3}x^0[/tex]
Apply rule: [tex]a^0=1,\:a\ne \:0[/tex]
[tex]=9\cdot \:1\cdot \frac{1}{y^3}[/tex]
Multiply fractions: [tex]a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}[/tex]
[tex]=1\cdot \frac{1\cdot \:9}{y^3}[/tex]
Refine
[tex]=\frac{9}{y^3}[/tex]
Thus, we conclude that:
[tex]\:9x^0y^{-3}=\frac{9}{y^3}[/tex]

It would look like this:
Cruise ships in the Jolly Cruise Line charge $14.45 per day for access to their premium WI- Fi. Each minute you use the internet you are charged $0.75. Which equation below represents this situation, if y represents the total amount you are charged for the day and a represents the number of minutes you use the Wi-Fi
y= 14.45x + 0.75
y= 14.45x - 0.75
y= 14.45 - 0.75x
y= 14.44 + 0.75x
Answer:
The equation y = 14.45 + 0.75x represent the situation.
Step-by-step explanation:
Given that:
Cost charged to access the premium wifi = $14.45
Cost charged each minute = $0.75
Let,
x represent the number of minutes
y represent the total amount charged
y = 14.45 + 0.75x
Hence,
The equation y = 14.45 + 0.75x represent the situation.
