jaun painted 4 portraits in 20 minutes. at that rate how many would he paint in 3 hours
Answers
Answer:
36 portraits
Step-by-step explanation:
4 portraits per 20 minutes. 20 minutes x 9= 3 hours. 9x4 portraits=36 portraits.
Answer:
48 portraits
Step-by-step explanation:
He can do 4 in 20 minutes. So, first figure out how many he can do in an hour. That's another 40 minutes. 40 minutes he does 8 portraits. So, 8 portraits plus 4 portraits is 16. That's one hour of painting. 16 portraits times 3 is 48, which is the amount he would paint in three hours.

-42=20=-2=13x (x=−2
Simplifying
-42 + 20 = 2x + 13x
Combine like terms: -42 + 20 = -22
-22 = 2x + 13x
Combine like terms: 2x + 13x = 15x
-22 = 15x
Solving
-22 = 15x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15x' to each side of the equation.
-22 + -15x = 15x + -15x
Combine like terms: 15x + -15x = 0
-22 + -15x = 0
Add '22' to each side of the equation.
-22 + 22 + -15x = 0 + 22
Combine like terms: -22 + 22 = 0
0 + -15x = 0 + 22
-15x = 0 + 22
Combine like terms: 0 + 22 = 22
-15x = 22
Divide each side by '-15'.

PLEASE HELP 15 POINTS The sum of the measures
of seven out of ten angles
in a decagon is 1086°. If the
three remaining angles are
equal in measure, what is the
measure of each angle?
Answers
Answer:
118
Step-by-step explanation:
1440-1086= 354
354/3=118
The measure of each angle is 118 degrees
The given parameters are:
Shape: DecagonSeven angles add up to 1086The remaining three angles are congruentThe sum of interior angles of a decagon is 1440.
Let each of the remaining three angles be represented with x.
So, we have:
[tex]1086 + 3x = 1440[/tex]
Collect like terms
[tex]3x = 1440 - 1086[/tex]
[tex]3x = 354[/tex]
Divide both sides by 3
[tex]x = 118[/tex]
Hence, the measure of each angle is 118 degrees

Answers
Answer:

Step-by-step explanation:
Step 1: Write equation
12 = 6 - 5x + 3x
Step 2: Solve for x
Combine like terms: 12 = 6 - 2xSubtract 6 on both sides: 6 = -2xDivide -2 on both sides: -3 = xRewrite: x = -3Step 3: Check
Plug in x to verify it's a solution.
Substitute: 12 = 6 - 5(-3) + 3(-3)Multiply: 12 = 6 + 15 - 9Add: 12 = 21 - 9Subtract: 12 = 12One group who studies milk says about 70 percent of milk purchased in schools is flavored.
