Answer:
Step-by-step explanation:
2x - 8 + x + 17 = 39
3x + 9 = 39
3x = 30
x = 10
2(10) - 8 = 20 - 8= 12 m for AB
10 + 17 = 27 m for BC
You want to find 25% of $12. 25% also equals 1/4. 1/4 of 12 (or 12 divided by 4) is $3.
Answer:
The third graph
Step-by-step explanation:
The third graph depicts the function f(x) = -1/2x because for every 1 unit decrease along the y-axis, you travel 2 units on the x-axis.
Also, the two points on the third graph can satisfy the equation.
Point 1: (-2,1)
f(-2) = (-1/2)(-2)
f(-2) = 1
Point 2: (0,0)
f(0) = (-1/2)(0)
f(0) = 0
Answer:
25x + 15
Step-by-step explanation:
5(5x+3)
5x5=25
5x3=15
25+15
A/7 + 5/7 = 2/7
1/7a + 5/7 = 2/7
1/7a + 5/7 - 5/7 = 2/7 - 5/7
1/7a = -3/7
7*(1/7a) = 7*(-3/7)
a = -3
