Answer:

  16

Step-by-step explanation:

Let "a" represent the measure of the angle. Then ...

  5a -30 = 2a +18

  3a = 48 . . . . . . . add 30-2a

  a = 16 . . . . . . . . . divide by 3

An angel is beyond measure, but this angle has measure 16.

Bus stop Restaurant sell 3/4 as many cheeseburgers as they do with hamburgers on any given day. If there are a total of 42 burge
schepotkina [342]

Answer:

24cb 18 hb

Step-by-step explanation:

Let's call C the number of cheese burger sold and H the number of hamburgers.

As the cheeseburger sold are 3/4 of hamburgers, we can represent with the following equation:

C= (3/4)H (equation 1)

The total of burgers sold are the total of cheeseburger plus the total of hamburgers, and the sum 42. The equation representing it is:

C + H = 42

Replacing C by its value of eq. 1:

(3/4)H + H = 42

(3/4)H + (4/4)H = 42

(7/4) H = 42

Dividing both sides by (7/4)

H = 42/(7/4)

H= 42*(4/7)

H= (42/7)*4

H= 6*4

H=24

Then, C is:

C=(3/4)H

C=(3/4)*24

C= 3*24/4

C=72/4

C=18

We can verify it summing C+H

C+H=24+18=42 verified!

Determining the input using an equation f (x) = -1/3x + 7
daser333 [38]

Answer:

19

Step-by-step explanation:

f(x)=2/3

2/3=-1/3x+7

Subtract 7 from both sides

2/3-7=-1/3x

-6 1/3 = -1/3x

Multiply both sides by -3

-3(-6 1/3)=-1/3x(-3)

19 = x
