Jane sells 8 times as many Volvos as Melissa. If the difference in their sales is 35, how many cars did Jane sell?

1 answer:

8 0

Here we have 2 variables we need to calculate:
x - how many Volvos Jane sold
y - how many Volvos Melissa sold

We write system of equations:
x = 8*y
x - y = 35
------------
8y - y = 35
7y = 35
y = 5
x = 8*5 = 40

Jane sold 40 cars.

Sue buys 5 pieces of fabric.Each piece is 1 7/10 yards long.What is the total length of the fabric she buys?One yard of the fabr

irina [24]

Answer:

The total length of fabric sue buys is 8.5 yards and total cost of the fabric is $42.5 .

Step-by-step explanation:

As given

Sue buys 5 pieces of fabric.

$Each\ piece\ is\ 1 \frac{7}{10}\ yards\ long.$

i.e

$Each\ piece\ is\ \frac{17}{10}\ yards\ long.$

$Total\ length\ of\ fabric\ sue\ buys = \frac{5\times 17}{10}\ yards$

$Total\ length\ of\ fabric\ sue\ buys = \frac{85}{10}\ yards$

In the decimal form

Total length of fabric sue buys = 8.5 yards

As given

One yard of the fabric costs $5

$Total\ cost\ of\ fabric\ sue\ buys = 8.5\times 5$

= $ 42.5

Therefore the total length of fabric sue buys is 8.5 yards and total cost of the fabric is $42.5 .

Fogoh!! Plz HELPi suck at math haha

Answer:

f(g(h(x))) = (sqrt(x) - 1)^4 + 4

Step-by-step explanation:

f(x) = x^4 + 4

g(x) = x - 1

h(x) = sqrt(x)

g(h(x)) = sqrt(x) - 1

f(g(h(x))) = (sqrt(x) - 1)^4 + 4

Why is 1/2 not useful as a benchmark to compare 5/8 and 9/10?

pentagon [3]

1/2 would not be a useful benchmark to compare these 2 fractions because both of them are greater than half. The benchmark fraction 1/2 is most useful when one fraction is less than half and the other more than 1/2. 5/8 is more than 4/8(1/2), and 9/10 is more than 5/10(1/2).
