What value of x satisfies the equation x/6-1/5=7/30

Mathematics

Makovka662 [10]4 years ago

We need to isolate x in order to find x. However, we need to have common denominators first.
\frac{5x}{30}- \frac{6}{30}  =  \frac{7}{30}
\frac{5x}{30}= \frac{13}{30}
Multiply by 30 on both sides.
5x=13
Divide by 5 on both sides to isolate x.
x= \frac{13}{5}

Aaron is going to a carnival that has games and rides. Each game costs $2.75 and each ride costs $4.75. Aaron spent $20.50 altog
serg [7]

Answer:

Step-by-step explanation:

2.75g + 4.75r = 20.50

g = 2r

2.75(2r) + 4.75r = 20.50

5.50r + 4.75r = 20.50

10.25r = 20.50

r = 20.50 / 10.25

r = 2 <==== Aaron went on 2 rides

g = 2r

g = 2(2)

g = 4 <==== Aaron played 4 games

check...

2.75g + 4.75r = 20.50

2.75(4) + 4.75(2) = 20.50

11 + 9.5 = 20.50

20.50 = 20.50 (correct)

Devin drank 1/8 gallon of orange juice, and his brother Sam drank 1/3 of the same gallon. How much of the gallon of orange juice
garri49 [273]
1/8+1/3. The denominator is changed to 24. 1/8 will turn to 3/24 and 1/3 will turn to 8/24. 3/24+8/24= 11/24.
