You borrowed 90 dollars from your grandmother. You pay back 15 dollars each week. Write in standard form an equation in which y is the amount of money owed after x weeks.

Answers

Answer 1
Answer: y = -15x + 90 

But that's not in standard form (it's in slope-intercept form). So, to change the equation into standard form, add 15x to each side.

y = -15x + 90
y + 15x = -15x + 90 + 15x
15x + y = 90

Hope this helped :)
Answer 2
Answer: y= money borrowed  minus  money paid times number of weeks

x = weeks
Ans:  y = $90 - $15x

Sybrina jogged 2 miles in 30 minutes. At this rate, how far would she jog in 90 minutes?At what rate did she jog each hour?

Answers

6 miles in 90 minutes and 4 miles per hour. 30 times two is 60 min so 2 miles times two is 4 miles. 

another 30 min is 90 min and another two miles is 6 miles.
2miles per 30min - 2 to 3
90/30=3x2=6

Answer:

x < -2

y > 1

Step-by-step explanation:

x < -3 + y

*x + y > -1

(-3 + y) + y > -1

-3 + 2y > -1

2y > -1 + 3

2y > 2

y > 1

*x < -3 + y

x < - 3 + (1)

x < -2

how do you do percent proportions? I'm learning those right now, and I have no idea what to do. my teacher isn't the best at explaining things. an example of what I don't get is "4% of what number is 10?" also things such as "16 is what percent of 64?"

Answers


Remember these tips:

=>  To turn apercent into a decimal, move the decimal point 2 places to the left.
4%means 0.04 ,  and  50% means 0.5 .

=>  To turn a decimal into percent, movethe point 2 places to the right.
0.062 means 6.2% .

=>  Inmath, whenever you see the word "of", it almost always means "times".
So your 2nd example means

                                    16 = (mystery number) x (64).

Divide eachside by 64 :    16/64 = mystery number = 1/4 = 0.25 .

Move the point 2places to the right.    0.25 = 25% .

Rounding 62.8 to the nearest square root, the result would be 63 square feet.

To round 62.8 to the nearest squareroot, you would look at the decimal part of the number.

If the decimal part is less than 0.5, you would round down to the nearest whole number.

If the decimal part is 0.5 or greater, you would round up to the nearest whole number.

In this case, the decimal part of 62.8 is 0.8, which is greater than 0.5. Therefore, you would round up to the nearest whole number.

To the nearest square foot is the same as to the nearest whole number. That would be 63.

Work out the balance for £1500 invested for 2 years at 3.7% per annum

Answers

Given:
Principal = 1,500
term = 2 years
interest rate = 3.7% per annum

Simple Interest = Principal * interest rate * term
S.I = 1,500 * 0.037 * 2
S.I = 111

Total value = 1,500 + 111 = 1,611

Compound interest
A = P (1+r/n)^nt
where n is the number of times interest is compounded. Assuming interest is only compounded once.

A = 1,500(1+0.037/1)^1*2
A = 1,500(1.037)²
A = 1,500(1.075369)
A = 1,613.0535
