7(a - 10) = 13 - 2(2a + 3)
7a - 70 = 13 - 4a - 6 = 7 - 4a
7a + 4a = 7 + 70
11a = 77
a = 77/11 = 7
a = 7.

Answer:

a=7

Step-by-step explanation:

we have

7(a-10)=13-2(2a+3)

Solve for a

7a-70=13-4a-6

Group terms that contain the same variable and move the constants to the other side

7a+4a=13-6+70

Combine like terms

11a=77

Divide by 11 both sides

a=7

Does this graph show a function?
Montano1993 [528]

9514 1404 393

Answer:

  A

Step-by-step explanation:

A vertical line intersects the graph in <em>more than one place</em>. As a consequence, we say the graph "fails the vertical line test." When the test fails, the graph is not a graph of a function.

Please help me with this question thanks. PLEASE I REALLY NEED HELP ON THIS PROBLEM
arlik [135]

Step One

Find the area of the base

A = s * s

s = 755.5 feet

Area = 755.5^2

Area = 570780.25 square feet.


Step two

Multiply the volume by 3

V = 1/3 B * h

3*V = B * h

V = 85600000

85600000 * 3 = B * h

256800000 = B * h


Step Three

Divide by B

B = 570780.25


256800000 = 570780.25 * h

256800000 / 570780.25 = h

449.91 feet = h

What is the solution to the system of equations? Use the substitution method. {y=−2x+53x−4y=2
klio [65]

y =  - 2x + 53x - 4y = 2 \\  y  = 51x - 4y = 2 \\  > y = 51 x - 4y \\  > 51x - 4y = 2
y = 51x - 4y \\ 5y = 51x \\ y =  \frac{51}{5} x
Substitute 51/5x into
51x - 4( \frac{51}{5} x) = 2 \\ 51x - 40.8x = 2 \\ 10.2x = 2 \\ x = 2 \times  \frac{10}{102}  \\ x =  \frac{10}{51}  \: aka \: 0.196
Substitute that into
y =  \frac{51}{5}  \times  \frac{10}{51}  \\ y = 2
Hope this helps. Answer should be correct. Unless your quadratic equation is wrongly stated.

Explain how the GCF is used to factor an expression?
scoundrel [369]

When factoring, it's easier to "pick out" the GCF first because it makes it simpler to factor even further. Otherwise, you will be troubled with lots of numbers and variables, so it will just get confusing.
