Answer:
e = 7.5
Step-by-step explanation:
Hi,
15 = e/0.5
You need to find what e equals. To do that, you need e all by itself. So to get e by itself in this equation, you need to multiply by 1/2 (same thing as 0.5). 15 x 0.5 is equal to 7.5.
To check your work, 7.5/0.5 is equal to 15.
So you know it's correct.
I hope this helps you :)
The answer should be b according to me
Answer:
Step-by-step explanation:
What is known....AC=75 AB=4 times BC AB+BC=AC
4(BC)+BC=75 Add like numbers
4(BC)+BC=5BC
5(BC)=75 get the variable(BC) alone by dividing both sides by the number(5)
5(BC)/5=75/5 Then simplify....5(BC)/5=(BC) and 75/7=15
(BC)=15
