Molly read 50 out of the 200 pages in her fiction book. Joel is also reading a fiction book, but his book has 280 pages in total

katrin [286]

Answer:

$x = 70$

Step-by-step explanation:

Given

Molly: 50 out of 200

Joel: x out of 280

Required

Find x

Start by representing the giving parameters as ration

Molly= 50 : 200

Joel = x : 280

From the question, the ratios are equivalent. So,

$50 : 200 = x : 280$

Convert to fractions

$\frac{50}{200} = \frac{x}{280}$

Solve for x

$x = \frac{50}{200} * 280$

$x = \frac{1}{4} * 280$

$x = \frac{280}{4}$

$x = 70$

Gabriel determined that his total cost would be represented by 2.5x + 2y – 2. His sister states that the expression should be x

meriva

✨ SAMPLE ANSWER ✨

The entire expression should be subtracted from 30. To subtract the quantity, distribute the negative sign, which changes the signs on the terms. So, the –2 changes to positive and gets added to 30 instead of subtracted from it.

4. Nine fruit juice bottles contain 4 1/2 litres of fruit juice between them.

brilliants [131]

Answer:

2 $\frac{1}{2}$ litres or 2.5 litres

Step-by-step explanation:

From the question, 9 fruit juice bottles contain 4 $\frac{1}{2}$ litres of fruit juice. Therefore, to find how many litres of fruit juice would be contained in 5 fruit juice bottles, you multiply 5 by 4 $\frac{1}{2}$ litres and you divide the product by 9.

i.e. Let the quantity of the fruit juice for 5 bottles be x.

9 juice bottles ===> 4 $\frac{1}{2}$ litres

5 juice bottles ===> x

∴x = $\frac{5 * 4\frac{1}{2} }{9} litres$

x = $\frac{5 * 4.5}{9} litres$

x = $\frac{22.5}{9} litres$

x = 2.5 litres or 2 $\frac{1}{2}$ litres

Hope this helps!!!

The triangle below has a total perimeter of 450 cm:

Korvikt [17]

Equation: 450 = 128 + 150 + n

work:

1st step:
128+150 = 278

2nd step:
450-278 = 172

answer: 172

3rd step (checking) :
450 = 128 + 150 + 172
450 = 278 + 172
450 = 450
