Answer:
Elena incorrectly used the slant height instead of the height.
Step-by-step explanation:
Answer:
x=30
y=15
z=150
Step-by-step explanation:
take 2x+x+90=180
we get x=30
and y=15 and z=150
You can round 375 up to 380 (because the ones is 5 or greater). 147 would be rounded to 150. Then add 380 and 150 and that will give you 530. 375+147≈530
EXPLANATION
Given the equation:
1/5m = 4-3/10m (Adding +3/10 to both sides)
1/5m +3/10m = 4 (Adding 1/5 + 3/10)
1/2m = 4 (Isolating m)
m = 2*4 (Multiplying)
m=8
ANSWER: m=8
