Answer:
x= 20
Step-by-step explanation:
The three angles add to 90 degrees
x+2x+x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10 from each side
4x +10-10 = 90-10
4x = 80
Divide by 4
4x/4 = 80/4
x = 20
answer is 250 which is D Because 250 of 24%=60, so subtract 60 from 250 it will give you 190
Answer:
nickels=13 and pennies=15
Step-by-step explanation:
0.05n+0.01p=0.80
-0.01(n+p=28)
0.05n+0.01p=0.80
-0.01n-0.01p= -0.28
0.04n=0.52
n=13
p=15
Answer:
see explanation
Step-by-step explanation:
Given a line joining the midpoints of 2 sides of a triangle, the midsegment
Then the midsegment is parallel to and half the measure of the third side of the triangle, thus
XY = 2KL = 2 × 42 = 84
Since J is the midpoint of XY, then
JY = 0.5XY = 0.5 × 84 = 42 and
JK = 0.5YZ = 0.5 × 76 = 38
