Answer:
B=-1
Step-by-step explanation:
Standard form is Ax+By=C.
In this case, Ax is x, By is 1/5y, and C is +2.
To isolate the 2 (the C), subtract x from both sides of the equation:
x+2=1/5y
-x -x
2=-x+1/5y.
Now, the value of B, the x value, is -1.
Answer:
13g
Step-by-step explanation:
10g + 8g = 18g
18g - 5g = 13g
A. c + 7 ≤ 3
c ≤ -4
a = 2
b. c - 3 > 1
c > 4
b = 3
c. c - 7 < 3
c < 10
c = 2
Answer:
Option C, 
Step-by-step explanation:
<u>Step 1: Set x to -1</u>
<u />



Answer: Option C, 
400% • x = 1
400/100 • x = 1
4x = 1
Divide each side by four.
4x/4 = ¼
x = ¼
The value of x is ¼.
