Very good but know one is answering my question:(
Answer:
x=0
Step-by-step explanation:
<u>Key skills needed: Proportions, Cross multiplication, One variable Equations, Multiplication</u>
1) Since this is a proportion, we need to cross multiply. A proportion is just 2 fractions equal to each other in this format.
---> Cross multiplication is when you multiply the first fraction's numerator by the second fraction's denominator, and you multiply the first fraction's denominator by the second fraction's numerator.
---> You set these products equal to each other.
2) So if we cross multiply it would be: 3(3x+5) = 5(3-2x)
---> If you multiply everything out, it would be --> 9x + 15 = 15 - 10x
3) Move the x terms to one side and the numbers to the other side
---> 9x + 10x = 15-15
4) Combine like terms (9x+ 10x= 19x) (15-15=0) 19x = 0
5) Divide by 19 and x=0.

Answer: In explanation
Step-by-step explanation: 350-170=4x
Solve 180=4x
45=x 45 minutes longer
4x+170=350 because you would want to subtract 170 from each side not add 170 to each side when simplifying
4x+170 because that is how much gas the tank can hold. You need to have 4x in the equation and 350 and 4x wouldn't make sense so use 4x and 170.
45 minutes as stated above.
Answer:
n ≤ 25
Step-by-step explanation:
If n represents "a number", then "a number is a maximum of 25" translates to ...
n ≤ 25 . . . . . a number is less than or equal to 25
Answer:
