Step-by-step explanation:

perimeter = 332

let the width be 'x'

then, length = 2x+7

perimeter = 2 (length+width)

332 = 2 ( 2x+7 + x )

332/2 = 3x + 7

166 - 7 = 3x

159/3 = x

53 = x

therefore, width (x) = 53

length = 2(53)+7

= 113

Raymond normally has a snack consisting of ten 12-calorie crackers. How many 20-calorie cookies would he have to eat to consume

ss7ja [257]

<h3>Answer: 6</h3>

Work Shown:

He eats ten 12-calorie crackers, so that is 10*12 = 120 calories total

If x is the number of 20-calorie cookies, then the total number of calories here is 20x. We want this to be 120, so,

20x = 120

x = 120/20 .... divide both sides by 20

x = 6

He must eat six 20-calorie cookies to get 120 calories total

If Sheila paid $797.50 in interest on a 5 year loan of $5,800 for her first car, what was the interest rate? (Make sure you’ve c

allochka39001 [22]

In calculating the interest on a car we have a formula

(interest rate/number of payments) x loan principal = interest.

Since, we have:
Interest rate = ?
number of payments = 60 ( 5 year loan x 12 months)
loan principal = 5800
interest = 797.50

We need to derive a formula to find the IR(interest rate)

(interest rate/60) x 5800 = 797.50
IR (5800) / 60 = 797.50
IR (5800) = 797.50 (60)
IR (5800) = 47850
IR = 47850/5800
IR = 8.25 %

Make x the subject of the formula х/a +b =c

klasskru [66]

Multiple by a both sides and the a in the first side will be canceled with the multiplication of a it will be x+b=ac and then you subtract b from both sides.

THE ANSWER WILL BE. X=ac-b

4/5 minus 1/3 plz i need help

IRISSAK [1]

Answer:

7/15

Step-by-step explanation:

Step 1

We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 4 by 3, and get 12.

Then we multiply 1 by 5, and get 5.

Next we give both terms new denominators -- 5 × 3 = 15.

So now our fractions look like this:

−

Step 2

Since our denominators match, we can subtract the numerators.

12 − 5 = 7

So the answer is:

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

Nope! So now we try the next greatest prime number, 3...

Nope! So now we try the next greatest prime number, 5...

Nope! So now we try the next greatest prime number, 7...

Nope! So now we try the next greatest prime number, 11...

No good. 11 is larger than 7. So we're done reducing.
