BY dividing by 1.5

Step-by-step explanation:

Since the variable is next to the number that multiplication so you would do inverse operation!

Answer: Possible answers:

- Isolating the varible

- Dividing both sides of the equation by 1.5

- x = $\displaystyle \frac{y}{1.5}$

Step-by-step explanation:

In this case, "finding x" will be setting the equation equal to x. In other words, we will isolate the variable x.

To do this, we will divide both sides of the equation by 1.5. Sine the x is being multiplied by 1.5, the inverse operation of multiplication is division.

y = 1.5x

$\frac{y}{1.5}$ = $\frac{1.5x}{1.5}$

$\frac{y}{1.5}$ = 1x

$\frac{y}{1.5}$ = x

x = $\displaystyle \frac{y}{1.5}$

After getting 5 new rocks, George gave half of his rock collection to Susan. If George gave Susan 36 rocks, which equation could

White raven [17]

Answer:

1/2 (x+5) = 36 should be the equation that is used to determine how many rocks George started with.

Step-by-step explanation:

Let 'x' be the number of rocks George had.

As George gave, after getting 5 new rocks, half of his rock collection to Susan which is = 36 rocks

It means after getting 5 new rocks George's total rocks = 72

Given that he gave half collection to Susan = 36

Thus, before inducting 5 new rocks Georg's total rocks were = 67

Thus,

1/2 (x+5) = 36 should be the correct equation.

solving

1/2 (x+5) = 36

Multiplying both sides by 2

1/2 (x+5) × 2 = 36 × 2

x+5 = 72

x = 72 - 5

x = 67

Thus, before getting 5 new rocks, the number of rocks George had = 67

Therefore,

1/2 (x+5) = 36 should be the equation that is used to determine how many rocks George started with.

A water bottle holds 3 1/3 c of water. A bowl holds 2 1/4 times the amount in the water bottle. How much water does the bowl hol

kodGreya [7K]

First you would put both numbers into improper fractions.

3 1/3 = 10/3 and 2 1/4 = 9/4

Multiply 10/3 * 9/4

10*9 = 90 and 3 * 4 =12

So 90/12 is your fraction. Reduce it, 7 6/12

7 6/12 = 7 1/2

So your answer is 7 1/2

Hope I helped :)

Find range ,median mode and mean of the following numbers -19,-11,-19,-18,-13,-19,-18,-11.0, 11,12

IrinaK [193]

Range= 31 because 12- -19 = 31 you subtract the lowest with the highest.

Mean= 8.3

Mode = -19 because you mostly see -19 there’s 3 -19 . :)))

Percents

Yuki888 [10]

Answer:

Percentage: 115%

Decimal: 1.15

Fraction: $\frac{23}{20}\\$

Step-by-step explanation:

<u>Percentages, Fractions, and Decimals</u>

Assume we set 100% as the original price of the food that Michael consumed. When he leaves a 15% tip for the waitress, he is really paying 100%+15%=115% of the original price.

Now we express 115% as a decimal, simply dividing by 100:

115% = 115/100 = 1.15

To express it as a fraction, we simplify the division instead of calculating it:

115% = $\frac{115}{100}$

Simplifying by 5:

115% = $\frac{23}{20}$
