Answer:
3 2/7 or 23/7 cms
Step-by-step explanation:
So we know the volume of a prism = L * W * H
And with the given info we know = L=28 and W=20 and Vol=1840
we solve for H and we get 23/7
Answer:
25%
Step-by-step explanation:
12=100%
3=25%
9=75%
Answer:
x=5.5
Step-by-step explanation:
Perimeter of ABCD=85
The perimeter is everything around the outside added together.
Form an equation:
3x+4+4x+6x-11+5x-7=85
Collect the like terms:
Like terms are terms that have the same powers and coefficient.
3x+4x+6x+5x=18x
4-11-7= -14
Put it back into an equation:
18x-14=85
Do inverse operations to find out what x is:
85+14=99
18x=99
99÷18=5.5 (we divide because, in algebra, when a number is next to a letter, it means times and as we want the inverse, you would have to divide)
x=5.5
Hope this helps :)
Paul must get 13 since Peter gets more more than Jane so Jane would get 7 and then peter would get 12
