If 3 quarts of paint are needed for 50 ft of fence, how many quarts are needed for 300 ft of fence?

Zina [86]

Answer:

Step-by-step explanation:

First, you would do a proportion

$\frac{3}{50}$ = $\frac{x}{300}$

Then you would cross multiply, getting 50x=900.

After that, you would do 900/50, which is 18.

Which question represents the line through (0,0) and (2,5)?

madam [21]

Answer:

y=5/2x

Step-by-step explanation:

The line needs to go through the points (0,0) and (2,5).

With y=5/2x, there is no y-intercept, so it starts on the origin, (0,0). With the slope 5/2, you would rise 5 (y) from the origin, and run 2 (x), which gives you the point (2,5).

PLS HELP What is the quotient?

ryzh [129]

Answer:

Step-by-step explanation:

$2\frac{1}{5}dividedby\frac{-1}{10}=2\frac{1}{5}*\frac{-10}{1}\\\\=\frac{11}{5}*\frac{-10}{1}\\\\=11*-2=-22\\$

Keep the first fraction, change division to multiplication and find the reciprocal(multiplicative inverse) of the second fraction

$\frac{11}{50}dividedby\frac{11}{50}=\frac{11}{50}*\frac{50}{11}\\\\ =1$

1/2(6x - 10) + -4x + 30

dybincka [34]

We'll do the distribute property for both.

1/2x6x=3x

1/2x-10= -5

SO....

3x-5+ -4x +30

Which is

-x + 25 or 25-x.

Hope this helps!
