14 thanks you so much

Set up the equation 88+7.25h=169. Now that we have the equation and the only variable to solve is h, we will begin the algebra.

1. Using the Subtraction Property of Equality, subtract 88 from both sides to get the equation 7.25h = 81

2. Now use the Division Property of Equality to divide both sides of the equation by 7.25. You should then get h = 11.1724...

Now assuming he is getting paid by the hour, the number of hours he needs to work to get the skateboard is 12.

on Saturday Joe ran m miles in 1.5 hours. On Sunday he ran four times as far in 6 hours. If his average speed for two days is 6

Mamont248 [21]

I think maybe 3 miles? Because 6 divided by 2 (the two days) equals 3. So if he ran a hour on Sunday then he ran 3 miles

Alba worked for 6 hr 45 min at $7.90 per hour. What numbers could she use to estimate how much money she earned? Estimate the am

Svetradugi [14.3K]

Answer:

$52
this estimate is a little low

Explanation:

a) I might choose 6 1/2 hours and $8 per hour, so the estimated earnings would be ...

6(8) +(1/2)(8) = 52 dollars . . . . estimated earnings

These values are purposely chosen so that one is a little high and the other is a little low, hopefully producing a closer estimate than if both numbers were high (as 7 hours, $8, for example).

b) Using 800 instead of 790 means the pay estimate is about 1/80 = 1.25% high.

Using 6 1/2 instead of 6 3/4 means the hours estimate is about 1/27 ≈ 3.7% low.

So, we expect the product of these values to be slightly low, perhaps by about 2.5%.

<em>Comment on estimating</em>

If you can estimate the error in the estimate with some reasonable accuracy, you can use that to adjust the estimate to a pretty close value.

Answer:

Option 4: A ║B

Step-by-step explanation:

Given the following statements:

$\displaystyle\mathsf{\overline{X}}$ is ⊥ $\displaystyle\mathsf{\overline{A}}$

$\displaystyle\mathsf{\overline{X}}$ is ⊥ $\displaystyle\mathsf{\overline{B}}$

We can apply the <u>Lines Perpendicular to a Transversal Theorem</u>, which states that if two lines intersect and are perpendicular to that same transversal, then those two lines are parallel.

In the given conditional statement, $\displaystyle\mathsf{\overline{X}}$ ⊥ $\displaystyle\mathsf{\overline{A}}$ and $\displaystyle\mathsf{\overline{X}}$ ⊥ $\displaystyle\mathsf{\overline{B}}$ , line $\displaystyle\mathsf{\overline{X}}$ is the transversal that cuts through both lines $\displaystyle\mathsf{\overline{A}}$ and $\displaystyle\mathsf{\overline{B}}$ .

Therefore, lines $\displaystyle\mathsf{\overline{A}}$ and $\displaystyle\mathsf{\overline{B}}$ are perpendicular to line $\displaystyle\mathsf{\overline{X}}$ . Hence, by the Lines Perpendicular to a Transversal Theorem, $\displaystyle\mathsf{\overline{A}}$ ║ $\displaystyle\mathsf{\overline{B}}$ .
