Answer:

Question 1: RS=47

Question 2: x=6

Step-by-step explanation:

Question 1:

Step 1: 3x+5=2x+15+6x-37

Step 2: 3x+5=8x-22/2

Step 3: 3x+5=4x-11

Step 4: x=16

Step 5: 2(16)+15=32+15=47

RS= 47

Question 2:

Step 1: 7x+2+25x-14=180

Step 2: 32x-12=180

Step 3: 32x=192  (divide 32 from each side)

x=6

Slope = Change in Y / change in x

Slope = (16 - -9) / (-2 - 3)

Slope = 25/-5

Slope = -5

Answer:

4 and 1/6 yards

Step-by-step explanation:

There are 36 inches in each yard since there are 3 feet in a yard and 12 inches in a foot. if you divide 150 inches by 36 inches you get 4 yards with a remainder of 6 inches which is 1/6th of a yard

Step-by-step explanation:

-4 times 2x is -8x, not 8x.

Answer:

Step-by-step explanation:

This is how we do it in college, I hope I can be of some help.

First, you multiple 9.6 miles with 5 minutes. Then, you divide your answer with 0.4 miles. Next, you cancel the two mile units because of division and then be left with 120 minutes.

9.6 miles x    5 minutes   =  48 miles x minute = 120 minutes

                      0.4 miles          0.4 miles

Answer:

The experimental probability --> [tex]\frac{13}{20}[/tex]

The theoretical probability --> [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Key skills needed: Experimental vs theoretical probability, Fractions

1) The first thing you need to understand is experimental probability vs theoretical probability. (Do not include this in your work!!)

- Theoretical probability is based on simple reasoning

- Experimental probability is based on the results a person gets (so the experiment you did by flipping the coin)

2) Now with this, let's start solving:

Hope you understood and have a nice day!! :D

Answer:

Experimental Probability: 65/100 We tested the probability 100 times, 65 of those times being heads. So %65 is our experimental probability (in percentage form) of flipping a coin and landing on heads. Simplified, 13/20 is our fraction.

Theoretical Probability: 50/100 or 1/2. There are two sides to a coin, and one is heads, so the theoretical probability is 1/2. In percentage form, the probability would be %50, or 50/100.

Step-by-step explanation:

-7 + 4r = -15

+7             +7

4r = -8

divide both sides by 4

r = -2

Hope this Helps!!!

Answer:

r=-2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4r−7=−15

Step 2: Add 7 to both sides.

4r−7+7=−15+7

4r=−8

Step 3: Divide both sides by 4.

4r/4=−8/4

r=−2

Answer:

  A = [tex]\frac{5\pi }{6}[/tex]

Step-by-step explanation:

Given that Cos A = [tex]-\frac{\sqrt{3} }{2}[/tex]

                cos A = [tex]cos (\pi -\frac{\pi }{6} )[/tex]

                       A =  [tex]\pi - \frac{\pi }{6}[/tex]

                      A = [tex]\frac{5\pi }{6}[/tex]

Step-by-step explanation:

h(t) = -16t² + 16t + 12

h(t) = -4(4t² - 4t - 3)

h(t) = -4(2t - 3)(2t + 1)

When h(t) = 0, we have t = 1.5 or t = -0.5.

Hence the zeroes are 1.5 and -0.5.

Answer:

x = -9/2

Step-by-step explanation:

-4x - 11 = 7

-4x = 7 + 11

-4x = 18

x = -18/4

x = -9/2

Answer:

I believe the answer is x=7

Step-by-step explanation:

3x and 4x-1 are corresponding sides and so are 14 and 18.

You cross multiply with the smaller triangle lengths at the top.

3x/(4x-1)= 14/18

Cross multiply to get

18(3x)= 14(4x-1)

54x=56x-14

Subtract 54x on the other side and add 14 to the other (or subtract 56x to the other side)

you get 14=2x and divide 14 by 2 to get x=7

Algebra I

Step-by-step explanation:

Step 1: Define

Point L(2, -4)

Point M(4, 6)

Step 2: Find Midpoint

Simply plug in your coordinates into the midpoint formula to find midpoint

Answer:

Amanda's

Step-by-step explanation:

Given :

3/6 + 2/4

The L. C. M of 6 and 4 = 12

(6 + 6) / 12

12 / 12

= 1

Renne's result = 5/10

Amanda's result = 1 whole

Hence, Amanda's result makes more sense.

Given:

The equation is

[tex]3.6y+7.5x=21600[/tex]

where, y is the number of cars and x is the number of trucks shipped.

To find:

The number of trucks that can be shipped if there are no cars.​

Solution:

We have,

[tex]3.6y+7.5x=21600[/tex]

If there are no cars in the cargo ship, then y = 0 because y is the number of cars.

Putting y=0 in the given equation, we get

[tex]3.6(0)+7.5x=21600[/tex]

[tex]0+7.5x=21600[/tex]

[tex]7.5x=21600[/tex]

Divide both sides by 7.5.

[tex]x=\dfrac{21600}{7.5}[/tex]

[tex]x=2880[/tex]

x is the number of trucks shipped.

Therefore, the number of trucks that can be shipped if there are no cars is 2880.
