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

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

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.

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

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%

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
