Answer:

91 divided by 14 = 6.5 is the length

Step-by-step explanation:

Whenever given an area and 1 given length always divide the area by the length to find the missing length.

Answer:

both questions is false

Answer:

The answer is 69

Step-by-step explanation:

The sum of a number and 98 means it equals 167. So all you have to do to find the missing number is plug it in to the equation.

?+ 98= 167

167-98=?

Answer:

3

Step-by-step explanation:

Given

- 1 - (- 6 + 10 ) ÷ - 1 ← evaluate parenthesis

= - 1 - (4) ÷ - 1

= - 1 - 4 ÷ - 1 ← evaluate division

= - 1 + 4

= 3

Answer:

the large numbers are

125,100,234,450,650,550

I hope u will be able to make it in an exponents form if u can not feel free to ask me

the small numbers are

10,20,30,40,50

Have a happy day ahead

Step-by-step explanation:

the line passes (-10, 0) and ( (0, 8) =>

the slope = (8-0)/(0-(-10) = 8/10 = 4/5

so, the equation :

y - 8= 4/5 ( x-0)

y -8 = 4/5 x

=> y = 4/5 x + 8

Answer:

6.72

Step-by-step explanation:

I multiplied both numbers by 10 to make it easier in my opinion. That made the equation 994.66 x 148

Then, I divided it until i got to the thousandths place. Lastly, i just rounded making it 6.72

Answer:

Yes

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given,

7+5(x-3)=27+5(x−3)=22

(Taking one of the equation)

=> 7 + 5(x - 3) = 22

=> 7 + 5x - 15 = 22

=> 5x = 22 + 15 - 7

=> 5x = 30

[tex] = > x = \frac{30}{5} [/tex]

=> x = 6 (Option c)

Answer:

Solve the equation for x:

Correct choice is c

Answer:

6/11

Step-by-step explanation:

The ratio says that, for every 6 girls, there are 5 boys.

For every 6 girls, there are 6 + 5 = 11 students.

So the fraction of  girls is

6/11

Answer:

Step-by-step explanation:

Rearrange the givens

3/5 - 2/5 - 6/7 + 3/14

1/5 - 12/14 + 3/14

1/5 -  9/14

The lowest common multiple is 70

14/70 - 45/70 = - 31/70

Answer:

x=-13

Step-by-step explanation:

divide 8 to both sides and get -13

Answer:

B = 65°

Step-by-step explanation:

Two "supplementary" angles add up to 180 degrees.

Therefore:

A + B = 180

(3x - 17) + (2x - 23) = 180

"Combine like terms" on the left side: the Xs and the numbers.

3x + 2x - 17 - 23 = 180

5x - 40 = 180

Add 40 to both sides:

5x = 220

And divide 5 on both sides:

x = 44

But we're looking for B, which is

(2x - 23) = 2(44) - 23 = 88 - 23 = 65

B = 65°

Step-by-step explanation:

She owes                                   70

She pays                     200

She gets                                   150

So the story is            200       220

She pays 200 and gets 220 including the furniture.

She 20 dollars to the good.

Answer:

8

Step-by-step explanation:

8.2, since 2 is smaller than 5, it would eliminate it, rounding it to just 8.

Answer:

B to (1, 0)

H to (3, -1)

F to (3, -3)

A to (-2, -2)

Step-by-step explanation:

An easy way to reflect points across axes is by counting the distance from the point you want to reflect to the axis you are reflecting across TWICE, and you'll be at the reflection point.

Answer:

I think it is C but it could also be A

Step-by-step explanation:

So here is my explanation. The perfect answer would be {all real numbers p<=345} however because that isn't stated let me explain the answers. A states that there could be 0-345 students however it also states that there could be a fraction of a student (its some wierd thing my Algebra teacher taught me). B states that f(p) is between that but that doesn't make sense. C states all positive intergers less than 345 which means a positive whole number. That means that it is all whole students less than 345 which makes sense however I am iffy cause I think it means there cannot be 345. D states all greater than 0 which exceeds the 345 limit.

Answer:

y = 7x - 50

Step-by-step explanation:

the standard form for a line equation is

y = ax + b

a is the slope.

b is the intercept with the y-axis (x=0).

we know, a = 7

so,

y = 7x + b

to get b we use the point (x = 7, y = -1)

-1 = 7×7 + b = 49 + b

b = -50

=>

y = 7x - 50

Answer:

around 502.65

Step-by-step explanation:

so, find the area of the circle first which is 16ft x 16ft x pi

after that, since a circle is 2 pi radians, just take 5/4 ÷ 2

then multiply that number over your area.

I'm not sure if I'm correct but this is what I know based on my limited understanding of it
