Isaiah earns $60 per week mowing lawns in the summer and shoveling driveways in the winter. He invested $220 in equipment. How long will it take him to earn $860? Find the equation and solve.
Answers
Answer:
18 weeks
Step-by-step explanation:
Create an equation where x is the number of weeks he works
60x - 220 will represent his profit, since he gets $60 a week but spent $220 in equipment.
Set this equal to 860, then solve for x, to find when he will earn $860
60x - 220 = 860
60x = 1080
x = 18
So, it will take him 18 weeks to earn $860

Aubrey finished 2/9 of a project on Monday and 1/4 of the project of Tuesday. How much of the project has Aubrey completed?
Answers
Answer:
17/36
Step-by-step explanation:
We have to find a common denominator, so the first common denominator for 4 and 9 is 36. 9x4=36, so we multiply 2 by 4, which equals 8. 4x9-36, so we multiply the 1 by 9, and get 9. Then we add the numerators, 8 and 9, and get 17. So it's 17/36

Jocelyn estimates that a piece of wood measures 5.5cm. If it actually measures 5.62 cm, what is the percent error of Jocelyn’s estimate?
Answers
Answer:
2.14% error
Step-by-step explanation:
Use the percent error formula:
| (observed - expected) / expected | x 100
Plug in the observed and expected values:
| (observed - expected) / expected | x 100
| (5.5 - 5.62) / 5.62 | x 100
Calculate:
= 2.14% error
So, the percent error of Jocelyn's estimate is 2.14%
Sasha uses 6.1 pints of white paint and blue paint to paint her bedroom walls. 2/5 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answers
Answer: 3.66 pints of blue paint.
Step-by-step explanation:
She used 2/5 of the total number of pints to paint white.
That number in pints is:
= 2/5 * 6.1
= 2.44 pints of white
The number of pints used to paint blue is therefore:
= 6.1 - 2.44
= 3.66 pints of blue paint.

0.2(3k+1)=-0.4-(-0.2-0.1K)
Answers
Answer:
k=−0.8
Step-by-step explanation:
Start with the equation: 0.2(3k+1)=-0.4-(-0.2-0.1K)
Use distributive property on each side of the equation. For the left side, distribute 0.2 into 3k and 1, and for the right side, distribute -1 into -0.2 and -0.1k. (We use a -1 because the negative sign on the outside of the parenthesis is equivalent to -1)
(0.2)(3k) + (0.2)(1) = 0.6k + 0.2
(-1)(-0.2) + (-1)(-0.1k) = 0.2 + 0.1k
New equation: 0.6k + 0.2 = -0.4 + 0.2 + 0.1k
Now we can combine like terms on the right side. (-0.4 and 0.2)
0.6k + 0.2 = 0.1k - 0.2
Now to get rid of k on one side, we can subtract 0.1k from the right side.
(0.6k - 0.1k) + 0.2 = (0.1k - 0.1k) - 0.2
0.5k + 0.2 = -0.2
Now we need to get 0.5k by itself, so we'll subtract the 0.2 on both sides.
0.5k + (0.2 - 0.2) = (-0.2 - 0.2)
0.5k = -0.4
To get k by itself, we must divide both sides by 0.5.
(0.5k / 0.5) = (-0.4 / 0.5)
k = -0.8

50% of 50% of x. PLEASE HELP I WILL GIVE BRAINLIEST
Answers
Answer:
25. 50 percent of 50 is 25 divided by 2.
Step-by-step explanation:
step1:Our output value is .50.
step2:we represent the unknown value with x
step3: from step1 above,.50=100%
step4: similarly,x=50%
step5: This results in a pair of simple equation:
.50=100%(1)
x=50%(2)
step6:by dividing equation 1 by equation 2 and noting that both the RHS(right hand side)of both equations have the same unite(%);we have
.50. 100%
____. = ____
x. 50%
step7: again,the reciprocal of both sides gives
x. 50
___ =. ___
50. 100
°x=0.25
therefore,50%of.50 is 0.25
