Answer:

AINT NOBODY CARES ABOUT SCHOOL

but the amount they spent each month was 145$

Answer:

A, B, D, E

Step-by-step explanation:

They all are negative numbers when solved except for C

Answer:

its b

Step-by-step explanation:

7 x 13 = 91

12 x 13 = 156

so u divide 143 by 13 and u get 11

Answer:

B

Step-by-step explanation:

The answer is B because you have to figure out how many $ he gets from mowing 1 yard which is found by dividing the number of money to the number of yard he mowed for one of the weeks it doesn't matter which one.The answer to how much he gets for 1 yard is 13 dollars so the last step is the divide 143 by 13

Step-by-step explanation:

Answer:

c. 4y=6x+8

Step-by-step explanation:

For lines to be parallel, they must have the same slope. To solve this problem, we need to isolate the y on one side of the equation (putting the equation into slope intercept form).

The equation itself must be divided by 2 to do that. We end up with y=1.5x-0.5. We need to find another equation that has 1.5 as the slope.

b. y=0.5x-1.5

c. y=1.5x+2

d. y=3x+4

e. y=2/3x-1

As we can see, the only other equation with a slope of 1.5 is C. Therefore, C is our answer.

Answer:

3

Step-by-step explanation:

15/4=3 with a remainder of 3 . You take the 3 from your answer and it becomes the whole number.

Answer:

Gummy bears $3.20/lbs

Jelly beans $7.50/lbs

Step-by-step explanation:

For this we will substitute gummy bear price for "x" and jelly bean price for "y" which creates this system (also assuming there is no sales tax involved):

1.8x + 0.6y = 10.26

1.2x + 1.5y = 15.09

Then once solved, answers come out to be (x,y) = (16/5,15/2) which is (3.2,7.5)

Answer: 114,041 steps

Step-by-step explanation:

No. of steps by Michelle = 98,094

No. of steps by Nadia = 15,947 + Michelle's steps

= 15,947 + 98,094

Nadia's steps = 114,041

Step-by-step explanation:

let the number represent X

5/100xx=10

5x/100=10

then you cross multiply

5x=100x10

5x=1000

divide both sides by 5

X=1000/5 =200

Step-by-step explanation:

Explanation:

There are 10 possible digits for the numbers (0,1,2,...,9), and 26 possible letters (A,B,C,.....,Z).

Since repetitions are allowed, we have that for each letter used, 26 still remain for the next choice, and for each digit used, 10 still remain for the next choice.

Hence, by the multiplication principle, the total different number of letter permutations is

A = lw

A = 9

9 = lw

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

9 = x² + 3x + 2x + 6

9 = x² + 5x + 6

x² + 5x = 3

Answer:

A = lw

A = 9

9 = lw

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

9 = x² + 3x + 2x + 6

9 = x² + 5x + 6

x² + 5x = 3

Answer:

88

Step-by-step explanation:

Let's find the length of one side. The perimeter will be 8 times that since it's a regular octagon.

[tex]d= \sqrt{(-4+(-4))^2+(8-(-3))^2} = \sqrt{0^2+(11)^2}= 11[/tex]

Perimeter has to be [tex]8\times 11 = 88[/tex]

m∠3 = 180 - m∠8 = 180 - 123 = 57

Step-by-step explanation:

Easy pie bro

Name: Kakashi Sensei

loraine walked 4 miles up, riana walked 3 miles right, the distance between them wil be the hypotenusa which is probably 5, yes? It forms a right triangle:

dist² = 3² + 4²

dist² = 9 + 16

dist² = 25

dist = [tex]\sqrt{25}[/tex]

dist = 5

now draw that triangle on the grid and there you go

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

4*a+b-(12)=0

Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 4a+b-12 = 0 and calculate its properties

Notice that when a = 0 the value of b is 12/1 so this line "cuts" the b axis at b=12.00000

b-intercept = 12/1 = 12.00000

When b = 0 the value of a is 3/1 Our line therefore "cuts" the a axis at a= 3.00000

a-intercept = 12/4 = 3

Slope is defined as the change in b divided by the change in a. We note that for a=0, the value of b is 12.000 and for a=2.000, the value of b is 4.000. So, for a change of 2.000 in a (The change in a is sometimes referred to as "RUN") we get a change of 4.000 - 12.000 = -8.000 in b. (The change in b is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = -8.000/2.000 = -4.000

Geometric figure: Straight Line

Answer:

Step-by-step explanation:

Without having a numerical value for a (or b), you can't "solve this equation."

You can, however, solve it for either a or b, but not both.

For a:  Subtract b from both sides.  This results in 4a = 12 - b.  Dividing both sides by 4 isolates a:  

        12 - b

a = --------------

            4

For b:  Subtract 4a from both sides.  Then:   b = 12 - 4a

Answer:

$73.37 is the new price.

Step-by-step explanation:

0.065 x 58 = 3.77

0.2 x 58 = 11.6

3.77 + 11.6 = 15.37

15.37 + 58 = 73.37

Answer:

100 miles.

Step-by-step explanation:

The combined speed of the 2 trains = 38 + 42 = 80 mph.

The time taken  before they crossed = 15:35 - 14:20

= 1:15 = 1.25 hours

Speed = distance / time, so

80 = distance / 1.25

Distance = 80 * 1.25

100 miles.

Answer:

100 miles

Step-by-step explanation:

A -----------P------------------ B

tom start at 14:20 with speed of 38mph

ben with speed 42mph

meeting time is 15:35

time difference is 75 min = 75/60 = 1.25 hours

distance travelled by tom is AP

AP = v * t

= 38 * 1.25

=  47.5 miles

distance travelled by ben is BP

BP = v * t

= 42 * 1.25

= 52.5 miles

distance between two cities is AB = AP + PB

= 47.5 + 52.5

= 100 miles
