Ok, so here's how you do it.Since you have those two 21s, you know those sides are equal, which means that you're gonna make an equation 38+2x=180 because all angles in a triangle have to equal 180 and whatever that x equal is also what that other missing angle is I think because of those two sides being equal and then you're going to solve that equation for x, so you wanna get x by itself. You subtract that 38 from the sides it's on and do the same to the other side, so 180-38, which equals 142. So now you have 2x=142, you have to get x by itself, so to do that you divide by 2 on both sides, so 142/2=71, so x=71.Hope that helps.

Beth filled 32 jars with paint. If each jar holds 1 pint of paint, how many gallons of paint did Beth use?
AnnyKZ [126]
If you would like to know how many gallons of paint did Beth use, you can calculate this using the following steps:

1 jar ... 1 pint of paint
32 jars ... x pints of paint = ?

1 * x = 1 * 32
x = 32 pints of paint

1 gallon ... 8 pints
y gallons = ? ... 32 pints of paint

1 * 32 = 8 * y
32 = 8 * y     /8
y = 32 / 8 = 4 gallons of paint

Result: Beth used 4 gallons of paint.

Answer:

Dave worked 60 hours.

Step-by-step explanation:

Let's assume that Dave worked a total of x hours.

Since Kate worked 5 hours less than Dave: x-5

And Sarah worked 10 more hours than Dave: x+10

Combined, the three siblings worked 185 hours.

(x)+(x+10)+(x-5) = 185\\x+x+10+x-5 = 185\\3x + 5 =185\\3x = 185 - 5\\3x = 180\\x = 180 \div 3\\x = 60

Dave worked 60 hours,

Kate worked 55 hours and Sarah worked 70 hours.

To check:

55 + 60 + 70 = 185 hours
