Answer: 12=7−3x+5x

Step 1: Simplify both sides of the equation.

12=7−3x+5x

12=7+−3x+5x

12=(−3x+5x)+(7)(Combine Like Terms)

12=2x+7

12=2x+7

Step 2: Flip the equation.

2x+7=12

Step 3: Subtract 7 from both sides.

2x+7−7=12−7

2x=5

Step 4: Divide both sides by 2.

Answer:

-10p

Step-by-step explanation:

-4p+(-6p)            for me I like to think of the negative or subtraction sign                

                          overpowering the positive or addition sign

so in this case

-4p-6p

then since the variable p is the same -4-6 is -10

the end result is -10p

Answer:

The slope is -1/2

The slope is after the "y=" but before the "x" variable.

Answer:

416.8 pounds.

Step-by-step explanation:

The mean weight of the 28 bears at a zoo is 413 pounds.

The Total Weight of the 28 bears = Mean weight × number of bears

= 413 pounds × 28 bears

= 11564 pounds

Fuzzy the bear, whose weight is 434 pounds, and Wuzzy the bear, whose weight is 505 pounds, were added to the zoo.

This means the total number of bears

= 30 bears because two additional bears were added

What is the new mean of the weight of the bears at the zoo?

New Mean = 11564 pounds + 505 pounds + 434 pounds/30 bears

= 12503 pounds /30 bears

= 416.76666667 pounds

Approximately to the nearest tenth = 416.8 pounds.

Answer:

A = 4 cm^2

Step-by-step explanation:

The area of a triangle is

A = 1/2 b*h

The base is 4 and the height is 2

A = 1/2 ( 4*2)

A = 1/2*8

A = 4 cm^2

Answer:

4

Step-by-step explanation:

A = BH/2

or Area = Base multiplied by Hieght divided by 2.

(b)4 x (h)2 = 8

8/2 = 4

Step-by-step explanation:

First you would plug in the 4 and 1/2 in the x and y's places, making the expression (4 - 2 (1/2))*(4 + 2 (1/2). Then you solve (below).

(4 - 2 (1/2))*(4 + 2 (1/2)

(4 - 1)*(4 + 1)

(3)*(5)

Answer:

g) x = 30

h) x = 30

i) m = 55

j) x = 24

k) k = 45

Step-by-step explanation:

G)

all angles of a triangle add up to 180.

the square in the bottom right of the triangle is 90 btw

2x + x + 90 = 180

3x + 90 = 180

3x + 90 - 90 = 180 - 90

3x = 180 - 90

3x = 90

3x/3 = 90/3

x = 30

H)

this is an Isosceles triangle.

that means the bottom two angles are equal.

75 + 75 + x = 180

x + 150 = 180

x + 150 - 150 = 180 - 150

x = 180 - 150

x = 30

I)

2m is supplementary to the bottom right angle of the triangle.

that means they add together to make 180.

80 + 30 + (180 - 2m) = 180

110 - 2m = 180 - 180

110 - 2m = 0

110 = 2m

110/2 = m

55 = m

J)

to save time I'm not going to write out the steps, its the same as the i.

2x + 3x + (180 - 120 ) = 180

5x + 60 = 180

5x = 180 - 60

5x = 120

x = 120/5

x = 24

K)

imagine this as a triangle and a square.

sorry I'm not sure how to explain this -.-

but the equation would be

k + k + 90 = 180

2k + 90 = 180

2k = 180 - 90

2k = 90

k = 45

L)

Im not sure how to solve this, I'm sorry :( hope you figure it out!

Answer:

10 Hours

Step-by-step explanation:

I believe the question is saying they rode for 8 days and of those 8 days they rode the whole 24 hours, so by that logic:

8 days x 24 hours: 192 Hours

192/18 people = 10.66

10.66 ~ 10 Hours

I hope this helped!

-16x = - 352     divide by -16 both sides

x = -352/-16

x = 22

Answer:−16x=−352

Divide both sides by −16.

x=  −352/−16

Divide −352 by −16 to get 22.

x=22

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given quadratic function is,

f(x) = (x + 6)(x - 3)

For x-intercept,

Substitute the value f(x) = 0.

(x + 6)(x - 3 = 0

x = 3, -6

So the x-intercepts will be,

(-6, 0) and (3, 0)

For y-intercept,

Substitute the value for x = 0,

f(0) = (0 + 6)(0 - 3)

     = -18

Therefore, y-intercept of the given quadratic function will be (0, -18).
