Divide 33 by 4, which is 8. Now do 8 times 7. 7 is the hours and 8 is the cost per hour, which is why me multiply. 8 times 7 = 56. Hope this helps
7x-y=14 :add 'y' to both sides
7x=14+y :divide both sides by 7
x=(14+y)/7 or x=2+(y/7)
7/40 abx i think thats the answer
Answer:
<u>There were 12 gold coins in the chest at the start.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
x = Number of gold coins in a chest
1/2x = Number of gold coins taken by the captain
1/4x = Number of gold coins taken by Sally
3 = Number of gold coins left
2. How many coins were in the chest at the start?
Let's write the following equation to solve for x:
1/2x + 1/4x + 3 = x
2x + x + 12 = 4x (Lowest Common Denominator is 4)
4x - 2x - x = 12 (Like terms)
x = 12
<u>There were 12 gold coins in the chest at the start.</u>
The slope of the line we seek must me the same as the slope of the given line because THE LINES ARE PARALLEL.
The two lines never meet.
The slope of the given line is -7.
See it?
Plug -7 and the given point into the point-slope formula.
y - (-6) = -7(x - 9)
Solve for y.
y + 6 = -7x + 63
y = -7x + 63 - 6
y = -7x + 57
