Answer:
500=2.5x+200
x=the amount of desserts.
500-200=2.5x
300=2.5x
x=120
Step-by-step explanation:
Answer:
c = 2
Step-by-step explanation:
Since 16 is over the variable c, first multiply both sides by c so the variable is not in the denominator of the fraction.
16/c(c) = 8(c)
16 = 8c Next, divide both sides by 8 to solve for c.
c = 2
Answer:
s=91/8
Step-by-step explanation:
- 4(2s-1)=75+12
- 8s-4=87
- 8s=91
- s=91/8
Answer:
x = -1
y = 3
Step-by-step explanation:
Add the two equations together.
You get:
4x = -4
You may notice that there is no <em>y</em>, and that is because the y's cancel out. -y + y = 0, so there's no use in putting <em>y </em>in.
x = -1.
Plugging x in, we get:
-1 - 2y = -7.
Move the -7 over to the left side.
6 = 2y
Therefore, y = 3.
We can check our answer by plugging the values in.
3(-1) + 2(3) is supposed to equal 3.
-3 + 6 = 3, and so we know our answer is correct.
Answer:
1 5/8 too short
Step-by-step explanation:
The cable on the truck is 18 and 3/8 ... to complete the fraction into a whole number we would need 5 more parts in order to complete the entire 8 parts of the fraction. This would make the cable a whole 19 feet. Since Ryan needs 20 ft, this would leave us needing 1 more foot. Therefore, the cable in the truck is
1 5/8 too short
