Answer:

x = 245

Step-by-step explanation:

The sum of integers x and y is 280; x + y = 280

If x is divided by 7, the quotient is y; x/7 = y so x = 7y

Now you have 2 equations:

x + y = 280

x = 7y

Substitute x = 7y into x + y = 280

7y  + y = 280

8y = 280

y  = 35

x = 7(35)

x = 245

Answer

x = 245

Answer:

Step-by-step explanation:

x + y = 280

x/7 = y                      Multiply both sides by 7

x/7 * 7 = 7*y

So x = 7y

Put 7y into the top equation.

7y + y = 280

8y = 280                   Divide both sides by 8

8y/8 = 280/8            

y = 35

====================

x + y = 280

x + 35 = 280

x + 35 - 35 = 280 - 35

x = 245

College student makes decorative Styrofoam Lions and Husky's which she sells each year. Each one uses 8 oz of Styrofoam and take
Travka [436]

Answer:

She should make 122 Styrofoam lions and 268 Styrofoam Husky's

The maximum profit, she makes is  $1109

Step-by-step explanation:

The given information are;

The volume required to make each lion = 8 oz

The time it takes to make each lion = 35 minutes

The amount of profit each lion brings = $2.50

The volume required to make each Husky = 12 oz

The time it takes to make each Husky = 20 minutes

The amount of profit each Husky brings = $3

Let the number of lion Styrofoam cups she makes = x

Let the number of Husky Styrofoam cups she makes = y

Therefore, we have;

x × 35 + y × 20 = 9650..........(1)

x × 8 + y × 12  = 3840.............(2)

Dividing equation (2) by 8 and making x the subject, we get;

x × 8/8 + y × 12/8  = 3840/8

x + 4/3·y = 480

x = 480 - 4/3·y

Substituting the value of x in equation (1) gives;

(480 - 4/3·y) × 35 + y × 20 = 9650

16800 - 80/3·y = 9650

y = 268.125

x = 480 - 4/3·y  = 480 - 4/3×268.125 = 122.5

Therefore, she can make 122 Styrofoam lions and 268 Styrofoam Husky's

The maximum profit, she makes is therefore given by the following equation;

The maximum profit = 122 × 2.5 + 268 × 3 = $1109.

skad [1K]
<span>They should produce 100 Explorers and 275 Grande Expeditions. To maximize revenue, we want to use all 375 frames. Since the more expensive bike take longer to make, we also want to use all 450 hours so we can make as many of the more expensive bikes as possible with the 375 frame. This helps us create a 2 variable system that can be solved. Let x=Explorers and y=Grande Expeditions x+y=375 2x+3y=450</span>
