Over [174]

Answer:

2062.50

Step-by-step explanation:

Interest = (Principle x rate x time)/100

Amount = Principle + interest

Principle = 750

Rate = 7%

Time = 25 years

(750 x 7 x 25)/100

= 131250/100

=1312.50

Principle = 750

Interest = 1312.50

Amount = 750 + 1312.50

Amount = 2062.50

Please help me on this algebra 1 question, i dont understand it
Y_Kistochka [10]

I believe the answer they're looking for is 3, but it's hard to tell, because there's a negative sign before the box, and a polynomial cannot contain a negative exponent.

Ignoring that sign though, the answer should be 3 because Polynomials typically have a term with each degree up to the maximum of the polynomial.

In this polynomial, there is a term with degree 4, degree 2,  and degree 0, but none for degree 3 or 1. Because of this, the only acceptable answer is 3.

Lena and 3 of her friends bought just enough food to go on a 12- day camping trip. Pete and Jane surprised them by showing up at
bekas [8.4K]

The number of people increased by 2.

This means as a ratio it is now 6/4 as many as originally planned.

6/4 can be reduced to 3/2.

The time and the number of people are inversely proportional, so the food would last 2/3 ( inverse is flipping the original ratio over) the original length of time.

This means the length of time the food lasts is reduced by 1/3, which is 33.3%

Solve for "c". a(b-c)=d
leva [86]

Answer:

c = b -d/a

Step-by-step explanation:

a(b-c)=d

Divide each side by a

a(b-c)/a = d/a

b-c = d/a

Subtract b from each side

b-c-b = d/a -b

-c = d/a -b

Multiply each side by -1

c = -d/a+b

c = b -d/a
