It’s 3 loads and $195 because you multiply 52 by 2 to get the total amount of bricks and then you divide 104 by 45 and you have a remainder of 14 which would be the last load and then divide 65 or whatever the price of the load of bricks to get 195

Answer:
32 feet
Step-by-step explanation:
The width of the doll house is 8/10 of the length of the doll house, so the actual house will have a width that is 8/10 of its length:
(8/10)(40 ft) = 32 ft
The actual house is 32 feet wide.
Answer:
Additive inverse property
Step-by-step explanation:
When you add opposites you get 0.
Another word for opposites is additive inverses.
This is the additive inverse property.
It says when you do -a+a or a+(-a) you get 0 for any number a.
For
solving system of equations, we can use either substitution where we plug one
equation into the other, or elimination where we combine the equations.
-
Using elimination,
you would to eliminate one variable from both equations, so you automatically would
get one equation with one variable!
- Using
substitution
means you are going to solve one equation for one variable and substitute with
its value in the other equation in order to get also an equation with one
variable.
Let's take an example ...
y+x=2 and y-2x = 1
<span>Using <span>elimination, we need to subtract these two equation; one from the other...
y+x=2
-
y-2x=1
-----------
0+3x=1
then
x=1/3 and then substitute into any equation to get y-value</span></span>
y+x=2
y+1/3 = 2 >>>>>
y=5/3NOW...<span>Using substitution
</span>y+x=2 and y-2x = 1 >>(y=1+2x)
Plug (y=1+2x) into y+x=2 and solve for x
y+x=2
(1+2x) + x =2
1+3x = 2
3x=1
again (and for sure)
x = 1/3plug in x=1/3 into any of the equations above to get y:
y+x=2
y+1/3=2
y=5/3DOne !!!!!!
I hope you got
the idea
