Answer:
-6
Step-by-step explanation:
Move the variable to the left hand side and change its sign.
5 - 2x + 4x = -7
Collect like terms.
- 2x + 4x = - 7 - 5
2x = - 7 - 5
Calculate the difference.
2x = -12
Divide both sides.
x = -6
Answer:
Graph A

Its mean graph should intersect x axis at x = 7 and x = - 1. This everything is satisfied by graph A.
Answer:
the answer is c
Step-by-step explanation:
Answer:
916 in.
Step-by-step explanation:
Step by Step.
5*10 = 50, and 50*2 = 100
10*4 = 40, and 40 * 2 = 80
(4*6)/2 = 12, and 12 * 2 = 24
10*10 = 100, and 100 * 2 = 200
16*16 = 256, and 256 * 2 = 512
Adding this together, we get: 916 inches.
-4(-5-b)=1/3(b+16) Multiply both sides by 3 to get rid of the fraction
-12(-5-b)=b+16 distribute the -12 to get rid of the parenthesis
60+12b=b+16 get the b on the left side and non b values to the right side
11b=-44 solve for b
b=-44/11 simplify the fraction
b=-4
3/5(t+18)=-3(2-t) multiply both sides by 5/3 to get rid of thefraction
t+18=-5(2-t) distribute the -5 to get rid of the parenthises
t+18=-10+5t get the t to the left side and non t values to the right
-4t=-28 solve for t
t=7
