4xAnswer: y=9-4x
Step-by-step explanation: Subtract 4X from both sides
So in this case expand the brackets where everything outside the brackets are multiplied into the brackets if that makes sense. Therefore 5 times 3m plus 5 time 2.
(5×3m)+(5×2)
=15m+10
do not add them together since they are not like terms
Do the same for the next question
which I think is already done for you since there is no expanding or adding to do.
Hope I am right if not sorry.
Multiply 1.5 times 7. That comes to 10.5 cups per week. Now convert it to quarts. There are 4 cups in one quart, so divide 10.5 by 4. That comes to 2.625 quarts per week. Now convert it to gallons. There are 4 quarts in a gallon, so divide 2.625 by 4. That comes to about 0.7 gallons a week, or 7/10.
30-60-90 triangle are set up as the shorter side being x. The longer side is x times √3. The hypotenuse is 2 times x.
So if your short side is 6, we do 6 times √3. This becomes 6√3, the first option.
