Ok so first we subtract 11 on each side so we get a-11=4b-4c then we do-4b on each side to gets a-11-4b=-4c finally divide -4 to each side to get a-11-4b/-4=c

Consider the expression

$a=11+4b-4c.$

First, separate variables: left 4c in the right side and all rest write in the left side:

$a-11-4b=-4c.$

Then multiply by -1:

$-a+11+4b=4c.$

At last, divide by 4:

$c=\dfrac{-a+11+4b}{4}.$

Ivan draws PQR on the coordinate plane.

Ivahew [28]

Answer:

Perimeter of PQR = 37 units (Approx.)

Step-by-step explanation:

Using graph;

Coordinate of P = (-2 , -4)

Coordinate of Q = (16 , -4)

Coordinate of R = (7 , -7)

Find:

Perimeter of PQR

Computation:

Distance between two point = √(x1 - x2)² + (y1 - y2)²

Distance between PQ = √(-2 - 16)² + (-4 - 4)²

Distance between PQ = 18 unit

Distance between QR = √(16 - 7)² + (-4 + 7)²

Distance between QR = √81 + 9

Distance between QR = 9.48 unit (Approx.)

Distance between RP = √(7 + 2)² + (-7 + 4)²

Distance between RP = √81 + 9

Distance between RP = 9.48 unit (Approx.)

Perimeter of PQR = PQ + QR + RP

Perimeter of PQR = 18 + 9.48 + 9.48

Perimeter of PQR = 36.96

Perimeter of PQR = 37 units (Approx.)

Varies directly with the number of

yulyashka [42]

Step-by-step explanation:

Let p and h represent pay and hours worked respectively,

p = kh

k = p/h = 148.5/18 = 8.25

p= 8.25h

90.75 = 8.25h

h = 11 hours.

Hope it helps! :)

What is the solution to the system of equations below? Y=-4/5x-6 & y=-30

Ainat [17]

So when you are trying to find the solution to the system of equations make sure that you have it where y= -4/5x-6 and y= -30 are written like this:

-30=-4/5x-6

And then solve for x:

Add 6 on both sides.

-24=-4/5x

Then multiply by the reciprocal of -4/5.

-5/4*-24=-5/4*-4/5x

x=30

But then you are gonna want to plug 30 in for x in y=-4/5x-6 to make sure that it is the same as y=-30.

The garden hose at Andre's house can fill a 5-gallon bucket in 2 minutes. The hose at his next-door neighbor's house can fill a

mina [271]

Answer:

The time it would take them to fill 750 gallons

= 200 minutes or 3 hours 20 minutes

Step-by-step explanation:

Step 1 :

We calculate the rate at which the hoses fill for Andre and His neighbor

For Andre

The garden hose at Andre's house can fill a 5-gallon bucket in 2 minutes.

The rate is calculated as:

5 gallon/2 minutes

= 2.5 gallons/minute

For His neighbor

The hose at his next-door neighbor's house can fill a 10-gallon bucket in 8

minutes.

= 10 gallon/8 minutes

= 1.25 gallon/minute

Step 2

Hence:

If they use both their garden hoses at the same time, and the hoses continue working at the same rate, the sum of their rate =

2.5 + 1.25 = 3.75 gallons per minute.

Step 3

The time it would take them to fill 750 gallons =

750 gallons ÷ 3.75 gallons per minute

= 200 minutes

= 3 hours 20 minutes
