-7.5 times 1/3=-2.5
To take 1/3 of something, multiply the original by the fraction.
Answer:
4 units
Step-by-step explanation:
The area (A) of a trapezoid is calculated using the formula
A = 
h(a + b)
where h is the height and a, b the bases
here A = 46, a = 6 and b = 17, hence
46 = h(6 + 17) ( multiply both sides by 2 )
92 = h(23) ← divide both sides by 23 )
h = 
= 4 units
Hope this helps with your questions :)
Answer:
Step-by-step explanation:
25.
Combine like terms.
4t+7=-33
subtract 7 from both sides
4t=-40
divide both sides by 4
t=-10
26.
Subtract 2a from both sides
5=7a-16
add 16 to both sides
21=7a
divideby 7 on both sides
a = 3
I'd suggest getting the app photomath or using cymath to help you with these problems. they give you the answer and how to get it step by step
Markup =35%
Model train cost =100
So 135%=100
1%=100/135
100%=100/35)*100=74.07
Original cost =74.07
