Hey there! I'm happy to help!
We want to multiply each term inside the parentheses by the number on the outside.
-3(-7)=21
-3(3z)=-9z
Therefore, our expression is 21-9z.
Now you know how to use the distributive property! Have a wonderful day! :D
$7.85 x .8 yards=$6.28.
$10-$6.28=$3.72 change back
X=2 because 5^3=125 and there you are
Rate * time = distance traveled
55 * 4 = 220 miles
Let's solve for "r" by bringing them all to one side.
-3r=6-4r
+4r +4r
r=6
So, r is equal to 6.
