The definition of a rate in math is, the speed of something being gained in a problem, let's say we have a hot pipe that can full up a pool in 6 hours, our rate would be 1/6 of the pool per hour.

Subtract three from either side. That will give you 4r=-21. Divide -21 by 4 and r will equal -5.25.

Which of the following is a factor of 2xy + 8y − 8x − 32?
melamori03 [73]

We are given

2xy+8y-8x-32

We can write it as

=2y*x+2y*4-8*x-8*4

we can see that 2y is in first two terms

and -8 is in last two terms

so, we can factor it out

=2y(x+4)-8(x+4)

now, we can see that x+4 is common in both terms

so, we can factor it out

=(x+4)(2y-8)

we can see that

x+4 is one of factor of terms

so, option-B..........Answer

In the number 5.3779, how does the value of 7 in the hundredths place compare to the value of the 7 in the thousandth place?
anygoal [31]

Answer:

  (b)

Step-by-step explanation:

The hundredths place is immediately to the left of the thousandths place. In our base-10 number system, moving a digit to the left one place increases its value by a factor of 10.

The value of 7 in the hundredths place is 10 times the value of 7 in the thousandths place.

Answer:

A. 29

B. 11

C. 10

D. 12

Step-by-step explanation:

A. 180 - 122 = 58

58 divided by 2 = 29

-

B. 180 - 37 = 143

x = 11

5 x 11 = 55

8 x 11 = 88

55 + 88 = 143 + 37 - 180

-

C. the small box in a triangle means right angle = 90

90 - 68 = 22

(2x - 2) we subtract before finding out what x is

22 - 2 = 20

2x = 20 divide by 2  = 10

x is equal to 10

-

D. to find the total, you must figure out what each equation is to add them up to make 180.

(8x + 3) + (2x + 9) + 4x = 180

add up the numbers with x and the numbers without them

14x + 12 = 180

subtract 180 - 12 = 168

168 divided by 14 = 12

x = 12

Hope this helped !!
