Answer:
the answer is 2,500 cm^3
Step-by-step explanation:
Answer:
y = -4/5x - 4
Step-by-step explanation:
y - y1 = m(x-x1)
4x + 5y = 20 ( subtract 4x on both sides)
5y = -4x + 20 (divide by 5 on each side)
y = -4/5x + 4
So we know one point is (0,4) y-intercept
now plug in (0,4)
y - 4 = -4/5(x-0) (Distribute -4/5 to x - 0)
y - 4 = -4/5x (now add 4 on each side)
y = -4/5x - 4
Answer:
12 hr. mowing lawns
28 hr. working at Mc Donalds
Step-by-step explanation:
Let t = time mowing lawns
then 40 - t = time working at McDonalds
7,5(40 - t) + 6t = 282
300 - 7.5t + 6t = 282
-1.5t = -18
t = 12 hr. mowing lawns
40 - t = 40 - 12 = 28 hr. working at Mc Donalds
Answer:
1.58
Step-by-step explanation:
So, we know there are 2.1 pounds, and for every pound it costs 0.75 dollars.
We can multiply the 2.1 by the 0.75 to find our answer.
The easiest way to do this is multiply the two numbers on 2.1 seperatly:
2 * 0.75 = 1.5
0.1 * 0.75 = 0.075
Then add them together:
1.5 + 0.075 = 1.575
Now we can round this to the nearest cent(hundreths place), and since the thousandths place is 5, we round up:
1.58
So our answer is $1.58!
Hope this helps!
