Answer:
Joel earns $7 per hour to mow his aunt's lawn. If he spends $6 on gas, how many hours, x , will he need to mow to have $ 29 left?
Step-by-step explanation:
The given equation is :
6x - 7 = 29
It is given that total hours be = x
Joel earns $7 per hour, so the total earning of Joel in x hours is = $ 7x
He spends $6 on gas, so = 7x - 6
He is left with $ 29 after spending on gas.
Therefore, the equation becomes :
7x - 6 = 29
Clearly, it can be seen that in this case, the given situation cannot be represented by the given equation, i.e. 6x - 7 = 29.
Answer:
10178.7602
Step-by-step explanation:
Volume of cylinder= π·r^2·h = π·9^2·40 ≈ 10178.7602
if 18 is the diameter than 9 would be the radius. to make the formula easier.
Answer:
To find the value of y, you would put your expressions (12y+3, and 51 equal to each other, because they are both the same length)
12y+3=51
12y=48 (51-3=48)
y=4 (divide both sides by 12, 48/12=4)
Then to find x you want to find the missing degree of the triangle
we already know that one degree is 63 and the other is 56,
A triangle equals 180 degrees
56+63=119
Then you want to subtract 119 from 180 to find out the missing degree
180-119=61
x=61 degrees
y=4 and x=61
Hope this helps ;)
Answer:
x = -4
Step-by-step explanation:
Isolate the x by substracting 2.3x from both sides, then subtract 21.6 from both sides.
After that, you will have 1.15x = -4.6. Divide both sides by 1.15 to get x = -4.
