Answer:

35x-35y

Step by step explanation: I

0.5(20x-50y+36)-0.25(100x+40y-12)

10x-25y+18+25x-10y+3 -------- after we distribute 0.5&-0.25

10x+25x-25y-10y+18+3. ---------we collect the like terms to add them or substract

13. Find PS.<br><br> 39<br><br> Р<br><br> \76°<br><br> R<br><br> 28°<br><br> S
baherus [9]

Answer:

21.38

Step-by-step explanation:

Find the diagram attached

In order to get PS, we need to get the length of QS first

According to triangle QRS;

QS =opposite

QR = 39(adjacent)

Using SOH CAH TOA

Tan theta = opp/adj

Tan 28 = QS/39

QS = 39tan28

QS = 39(0.5317)

QS = 20.74

Get PS

sin theta = QS/PS

sin 76 = 20.74/PS

PS = 20.74/sin76

PS = 20.74/0.9703

PS = 21.38

Hence the length of PS is 21.38

What is the slope of a line with the coordinates 0,9 and -3,4
Semmy [17]

Answer:

The answer is -5/3

Step-by-step explanation:

<h3><u>Given</u>;</h3>
  • x₁ = 0 and x₂ = (-3)
  • y₁ = 9 and y₂ = 4

Slope of a line

  • m = y₂ – y₁ ÷ x₂ – x₁

Now,

m = y₂ – y₁ ÷ x₂ – x₁

m = 4 – 9 ÷ 0 – (-3)

m = -5 ÷ 3

m = -5/3

Thus, The slope is -5/3

The following chips are placed in a bucket: 5 red, 3 yellow, 4 blue, and 1 green. One chip is randomly selected from the bucket.
maria [59]
So,

If we add them together, we get
5 + 3 + 4 + 1 = 13

Since there are 4 blue chips, the probability would be 4 out of the total number of chips, or 4/13.

The \ probability \ of \ the \ random \ selection \ of \ a \ blue \ chip \ is \ \frac{4}{13} .
