2 = 9
3 = -6
4 = - 4
Step-by-step explanation:
Hello there!
For each problem we are going to want to plug in the value of x (which is given) and find the total value of the expression
For #1
8(-4) + 4(-4)
8 * - 4 = -32
4*-4=-16
-32+(-16)=-48
So the answer to #1 is -48
For #2
9(3)-18
9*3=27
27-18=9
so the answer to #2 is 9
For #3
-2(8)+10
-2*8=-16
-16+10=-6
so the answer to #3 is -6
For #4
5(-3)+11
5*-3=-15
-15+11=-4
So the answer to #4 is -4

Answer:
That number is 0.45
Step-by-step explanation:
3/5x = 2x - 63/100
0.63 = 2x - 3/5x
0.63 = 10/5x - 3/5x
0.63 = 7/5x
7x = 0.63*5 = 3.15
x = 3.15/7
