Answer:
2x + 1.5y = 15
Step-by-step explanation:
2x + 1.5y = 15 because just plug in the variables.
A ratio is used to describe how two or more quantities are related. For example, we might say that a fruit drink calls for sugar crystals to be mixed with water in a ratio of 2:6. This means that for every 2 scoops sugar crystals, there will need to be 6 ounces of water. If there were 200 scoops of sugar crystals, there would need to be 600 ounces of water.
Answer:
-3/2
Step-by-step explanation:
y=mx +b
where m is the slope and b is the y intercept
we just need to rewrite 3x+2y+18=0 to look like that
We need to get y by itself
3x+18= -2y
we need y to be positive and to have no number in front of it (no coeficcent)
y= -3/2x-9
the slope is therefore -3/2

Answer:
x=19
Step-by-step explanation:
The perimeter of the right triangle is
P=9+12+15 =36
The perimeter of the left triangle is
P =x-7+ x-7+ x-7 = 3x-21
Set them equal
36 = 3x-21
Add 21 to each side
36+21 = 3x-21+21
57 = 3x
Divide each side by 3
57/3 = 3x/3
19 =x
