Answer:
The solution is (15, 11) There is only one solution.
Step-by-step explanation:
Solve this system using substritution. In the second equation replace x with 2y - 7, obtaining:
4(2y - 7) + y = 71, which simplifies as follows:
8y - 28 + y = 71, or
9y = 99. then y must be 11. If y is 11, then x = 2y - 7, or x = 2(11) - 7 = 15
The solution is (15, 11) There is only one solution.

What are the steps for 2x+1=7
Answer:
x = 3
Step-by-step explanation:
Step 1:
Subtract 1 from both sides
2x + 1 = 7
2x + 1 - 1 = 7 - 1
2x = 6
(1 - 1 will cancel itself out on the side with the variable.)
Step 2:
Divide both sides by 2
2x = 6
2x ÷ 2 = 6 ÷ 2
x = 6 ÷ 2
(2 divide by 2, will cancel itself out on the side with the variable.)
Step 3:
Solve for x
6 ÷ 2 = 3
x = 6 ÷ 2 = 3
x = 3

If x=2,find the value of x²+1/x²
Answer:
17/4 or 4 1/4
Step-by-step explanation:
Substitute x = 2 into the expression x² + 1/x².
(2)² + 1/(2)²Evaluate the exponents in the expression.
(4) + 1/(4) 4 + 1/4Multiply 4 by 4/4 to get a common denominator of 4.
16/4 + 1/4Add the numerators together.
17/4The value of x² + 1/x² if x = 2 is 17/4, or 4 1/4.

Michael starts a website for people in his town to share news and photos. Before launching the website, he has his friends and family sign up. Then, he uses the equation shown to estimate the number of users, y, who will have signed up x weeks after he officially launches the website.
y = 82(1.045)x
part A: What is the rate of growth Michael expects each week after launching the website?
A.
104.5%
B.
95.5%
C.
0.045%
D.
4.5%
Answer:
D. 4.5%
Step-by-step explanation:
Michael expects the rate of growth to be 4.5% each week because in the equation inside the parenthesis is 1.045 meaning it has already had 1 added to the original percentage so subtract 1 from 1.045 then move the decimal twice to the right and change it into a percentage sight which will give you 4.5%
the growth rate per week is 4.5% Micheal can expect.
What is rate?Rate is a measurement to determine the change in one quantity with respect to another quantity.
The given equation is,
y = 82(1.045)x,
Where y represents number of people and x represent number of week.
After 1 week, x=1
y=82×1.045
The multiplying factor is 1.045
It implies that after 1 week growth increase by, 0.045
The percentage value of 0.045 is 4.5%
So the growth rate per week is 4.5%.

30 is 120% of what number? show ur work
Answer:
30 is 120% of 25
Step-by-step explanation:
30 = 120% of y
[tex]\frac{120}{100}[/tex] × y = 30
After multiplying both sides by 100 and dividing both sides by 120, we have
y = 30 × [tex]\frac{100}{120}[/tex]
y = 25

Pam ordered a circular hot tub cover with a diameter of 80 inches. Find the area of the hot tub cover.
Answer:
5026.55in²
Step-by-step explanation:
Area = πr^2
radius (r) is half of the diameter, hence the radius is 40 inches
So after plugging that in, the equation should look like
Area = π(40)^2
A = 1600π ≈ 5026.55
The units for this is in² so just add that in the end

The short sides of a rectangle are 2 inches. The long sides of the same rectangle are three less than an unknown number of inches.
If the area of the rectangle is 22 square inches, what is the value of the unknown number?
Given:
Short sides of a rectangle = 2 inches.
Area of the rectangle = 22 square inches.
The long sides of the same rectangle are three less than an unknown number of inches.
To find:
The unknown number.
Solution:
Let x be the unknown number. Then the longer side of the rectangle is (x-3) inches.
We know that the area of a rectangle is
[tex]A=length\times width[/tex]
The area of the rectangle is 22 square inches.
[tex]22=2(x-3)[/tex]
Divide both sides by 2.
[tex]11=x-3[/tex]
Add 3 on both sides.
[tex]11+3=x-3+3[/tex]
[tex]14=x[/tex]
Therefore, the value of the unknown number is 14.
