Step-by-step explanation:
7(28)=196
7(20)=140 + 7(8)=56
140+56=196
196=196
The appropriate choice is ...
1) 4x-5y=-5 and 3x+10y=-20
Answer:
m= 5
Step-by-step explanation:
-7m-5(m+5)= -85
-7m-5m-25= -85
-12m-25= -85
-12m= -60
/-12 /-12
m= 5
Isolate the k. Note the equal sign. What you do to one side, you do to the other.
First, subtract 2m from both sides
8k + 2m (-2m) = 3m (-2m) + 4
8k = m + 4
Next, divide 8 from both sides
(8k)/8 = (m + 4)/8
k = (m + 4)/8
k = m/8 + 1/2
k = m/8 + 1/2 is your answer
