Answer:
-55
Step-by-step explanation:
7x-6y=2
-2x-y=3
by substitution method
y=3+2x
7x-6(3+2x)=2
7x-18-12x=2
-5x=20
x=-4
-2(-4)-y=3
8-y=3
-y=3-8
y=5
therefore the value of x=4 and that of y=5
5x-7y=5(-4)-7(5)
=-20-35
=-55
Answer:it should be true
Step-by-step explanation: for example 2+2c^2=18 18-2 is 16 divide by 2 then square root this etc
8,1/8 = 65/8
5,3/4 = 23/4
Multiply 65/8 by 23/4
= 1495/32
= 46 23/32 square feet (if they want it kept as a fraction)
Or 46.72 square feet (if they want a decimal)
Answer:
Men it's a really long process and I've just woken up men
Answer: 2.5 ft
Step-by-step explanation:
The volume of a rectangular prism is given by the following formula:
(1)
Where:
is the length of the base
is the width of the base
is the height of the prism
On the other hand, tha area of a rectangle is:
(2)
Then, we can rewrite (1) in terms of (2):
(3)
Now, we know the value of the volume and the area of the base:


Substituting these values in (3):
(4)
Isolating
:
This is the height of the truck
