So the formula for volume is V=(l)(w)(h)
They already gave you the volume so it’s just basic algebra.
730= 10x(9)
81= 10x
8.1=x
So x is equal to 8.1 but in the question it’s say about which indicates to round it so it should be 8 but I’m not 100% sure.
Answer:
75kg
Step-by-step explanation:
Decrease =25÷100×100kg
= 0.25×100kg
= 25kg
Decrease 100kg by 25%=100kg-25kg
= 75kg
Problem
One number is eight less than five times another. If the sum of the two numbers is 28, find
the two numbers.(separate your answers using commas)
Solution
for this case we can define the following notation:
Let x and y the two numbers and we have:
x= 5y -8
and we also know that:
x+ y = 28
Replacing we got:
5y -8 +y = 28
6y = 28+8
6y= 36
And y = 6
And for x we got:
x= 5*6 -8= 30 -8 = 22
Answer:
y= 11 | 19 | 27 |35 | 43 |
