Beth filled 32 jars with paint. If each jar holds 1 pint of paint, how many gallons of paint did Beth use?

Snowcat [4.5K]

I think 4 gallons.
There's 2 pints in 1 quart
And 4 quarts in 1 gallon.
So, 32/2 = 16 then divided by 4 = 4.

D:x\geq10\\\\
\sqrt{n+5}-\sqrt{n-10}=1\\
\sqrt{n+5}=1+\sqrt{n-10}\\
n+5=1+2\sqrt{n-10}+n-10\\
2\sqrt{n-10}=14\\
\sqrt{n-10}=7\\

expeople1 [14]

Answer:

I think the answer is

$x = \frac{9}{7}$

Step-by-step explanation:

Reason :

$4x - 2 + 3x - 7 = 0 \\ collect \: like \: terms \\ 4x + 3x - 7 - 2 = 0 \\ 7x - 9 = 0 \\ 7x = 9 \\ x = \frac{9}{7}$

Olivia made 14 outfits for her dolls. Each outfit used 3/5 of fabric. If she started with 10 3/4 yards of fabric, how much did s

Zepler [3.9K]

Answer:

0.1 yards of fabric

Step-by-step explanation:

Data provided in the question:

Number of outfits made for the doll = 14

Fabric used in each outfit = $\frac{3}{5}$ yards of fabric

Starting fabric available = 10 × $\frac{3}{4}$ or $\frac{30}{4}$ yards

Now,

The total fabric used in making the outfits of 14 dolls

= 14 × $\frac{3}{5}$ yards of fabric

= $\frac{42}{5}$ yards of fabric

Therefore,

The fabric left after making the outfits

= Fabric available in the start - Fabric used in making the outfits

= $\frac{30}{4}$ yards - $\frac{42}{5}$ yards

= $\frac{30\times5-42\times4}{4\times5}$ yards

= $\frac{150-168}{20}$ yards

= $\frac{2}{20}$ yards

= 0.1 yards of fabric
