Answer:

C

Step-by-step explanation:

From the midsegment theorem we can conclude that

QR = \frac{1}{2} NP

Using QR = 3x + 2 and NP = 2x + 16, then

3x + 2 = \frac{1}{2}(2x + 16) = x + 8 ( subtract x from both sides )

2x + 2 = 8  ( subtract 2 from both sides )

2x = 6 ( divide both sides by 2 )

x = 3

As a check

QR = 3x + 2 = 3(3) + 2 = 9 + 2 = 11

NP = 2x + 16 = 2(3) + 16 = 6 + 16 = 22

Thus QR is one half NP is confirmed

Answer:

<h2>C.  QR=1/2NP  ;  x=3</h2>

Step-by-step explanation:

QR=1/2NP ⇔ NP=2QR ⇔ 2x+16=2(3x+2) ⇔ 2x+16=6x+4 ⇔ 12=4x ⇔ x=3

Which graph shows the solution to the inequality <br> |x+3| ≥ 2?
KIM [24]

Answer:

2nd number line

Step-by-step explanation:

When there is an absolute value inequality of the form  |x+a| ≥ b,

We can say that the solution set (in a number line) would be:

  • we take the point x = -a
  • then we go b units in both directions (left and right)
  • start from those 2 points and draw arrows in both directions (left & right)

Keeping these points in mind,

|x+3| ≥ 2

we start from x = -3

we go 2 units left and right, so we arrive at x = -5 and x = -1

then we draw arrows to both sides

<em>looking at the choices, </em><em>we see 2nd answer choices (graph) portrays it correctly.</em>

Kendra earns $70 per week mowing lawns. She saves 60% of the money she earns each week. How many weeks will it take Kendra to sa
katrin [286]

Answer:

5 weeks

Step-by-step explanation:

Let's find how much money she saves a week by multiplying the decimal form of 60% and $70.

To get the decimal form of a percent you have to move the decimal to the left twice, like this: 60 ---> .60

Now that we have the decimal form of the percent we can multiply it by the 70 to find how much she saves a week:

(70)(.6) = 42

Therefore, Kendra saves $42 each week.

To find how many weeks it will take Kendra to buy the game system you divide $210 by the $42. Like this:

(210)/(42) = 5

All in all, it will take Kendra 5 weeks to save enough money to buy a game system that costs $210.

Whole numbers are positive numbers without decimals.  First, list all the whole number factors of 36:

1 and 36

2 and 18

3 and 12

4 and 9

6 and 6

Next, see which one of those pairs has the highest sum:

1+36=37

2+18=20

3+12=15

4+9=13

6+6=12

The greatest possible sum the numbers can have is 37.
