Answer:
whats x?
Step-by-step explanation:
In this question, you're solving for y:
Solve for y:
-3(4y - 7) - y = -2(y - 2)
<em>use the distributive property:</em>
-12y + 21 - y = -2y + 4
<em>combine like terms:</em>
-13y + 21 = -2y + 4
<em>add 2 to both sides</em>
-11y + 21 = 4
<em>subtract 21 from both sides</em>
-11y = -17
<em>divide both sides by -11</em>
y = 17/11
You would check your answer by plugging in 17/11 to the y variables.
Answer:
4
Step-by-step explanation:
The symbol is ">" (not "≥") so the line is dashed, not solid.
A solid line is used to indicate the boundary line is part of the solution, as it is in the "or equal to" case.
Answer:
30 hours
Step-by-step explanation:
Distance = Speed * Time
We can use that formula to plug in the numbers given.
1778mi = 61.7mph * Time
1778/61.7 = 28.817 (approx.)
So the answer will be about 30 hours
