Answer:
18
Step-by-step explanation:
1) 90 --- 100%
x --- 20%
x = 90*20/100 = 18
2)
20 % = 20/100 = 0.2
20 percent (0.2) of (*) 90 = 0.2*90 = 18
Answer:
x=5
y=0
Step-by-step explanation:
KL = JM
3x-y = 15
and JK = LM
4x -4y = 20
Divide this equation by 4
x-y= 5
Multiply by -1
-x+y =-5
Add this to the first equation
3x-y = 15
-x+y =-5
-----------------
2x = 10
Divide by 2
2x/2 = 10/2
x =5
x-y = 5
5-y = 5
-y = 0
y =0
First add 2 to both sides, next add 2 + 3 to get 5, next break down the equation into two problems which would be 2x - 5 = 5 and -(2x - 5) = 5, NOT 2x - 5 = -5, so this is the FIRST incorrect step, while step 4 is incorrect because its suppose to be 2x = 5 not 10, that's the second step, not first so answer is:
