Answer:

Step1: Subtract <u>(cx+d)</u> from both sides of the given equation

Therefore the value of x in the given equation is $x=\frac{a-d}{b+c}$

Step-by-step explanation:

Given equation is a-bx=cx+d

To solve the given equation for x :

a-bx=cx+d

Step1: Subtract (cx+d) from both sides of the given equation

a-bx-(cx+d)=cx+d-(cx+d)

a-bx-cx-d=cx+d-cx-d

a-bx-cx-d=0

Rewritting the above equation as below

a-b-bx-cx=0

(a-b)-x(b+c)=0 (here combining the like terms )

-x(b+c)=-(a-d)

Therefore the value of x in the given equation is $x=\frac{a-d}{b+c}$

Answer:

30 c + 100 m = 700

c+ m = 14

Step-by-step explanation:

Hi, to answer this question we have to write a system of equations.

The product of the number of movies where the song was played (m) multiplied by the earnings per movie (30) plus the product of the number of commercials where the song was played (m) multiplied by the earnings per commercial, must be equal to $700.

30 c + 100 m = 700

The number of movies (m) plus the number of commercials (c) is equal to 14.

c+ m = 14

The system is:

30 c + 100 m = 700

c+ m = 14

If one worker can assemble 9 products per hour, and another worker can assemble 6 products per hour, how long will it take them

leva [86]

Answer:

3 hours 20 minutes

Step-by-step explanation:

Together, the workers can assemble 9 + 6 = 15 products per hour. So the assembly of 50 products will take ...

(50 products)/(15 products/hour) = 50/15 hours = 3 1/3 hours

The two workers can assemble 50 products in 3 1/3 hours.

1. Greg Forrester's charge account statement showed a previous balance 20 points

Slav-nsk [51]

Answer:

Option $152.19

Step-by-step explanation:

Data provided in the question:

Previous balance = $152.35

Finance charge = $1.78

New purchases of $45.23 and $15.67

Payment = $50.00

Credit = $12.84

Now,

New Balance

= [Previous balance + Finance charge + New purchases ] - [ Payments + Credits ]

= [ $152.35 + $1.78 + ($45.23 + $15.67) ] - [$50.00 + $12.84 ]

= $215.03 - $62.84

= $152.19

Hence,

Option $152.19

Akeem and Jack are discussing their friend's new swimming pool. It is rectangular in shape. Akeem says he knows that it has a pe

schepotkina [342]

Answer:

The length of swimming pool is 10 yards.

Step-by-step explanation:

Given,

Perimeter= 90 feet

Width= 5 yards

As we have to find the length in yards, therefore, we will convert perimeter in yards also.

As we know,

1 Yard = 3 feet

Therefore,

Dividing the perimeter by 3 to convert it into yards.

$90\ feet = \frac{90}{3} \ yards\\90\ feet=30\ yards$

The formula of perimeter of rectangle is;

P= 2(l+w)

Putting values of perimeter and width;

$30=2(l+5)\\30=2l+10\\2l=30-10\\2l=20\\l=\frac{20}{2} \\l=10$

The length of swimming pool is 10 yards.
