Answer:

17/70

Step-by-step explanation:

First use PEMDAS which is the order to solve questions like these.

Parenthesis

Exponents

Multiplication

Division

Addition

and Subtraction

There is one parenthesis which has a (-1/4) so let's start with that, we know that when there is a negative and a positive sign the negative out rules the positive

3/5-1/4 divided by 7/10 (Sorry I don't have the division sign on my device)

There are no exponents or multiplication but there is division

-1/4 divided by 7/10 is -5/14

3/5-5/14 is 17/70

Thus, our answer is 17/70

A side of a square is 10 cm longer than the side of an equilateral triangle. The perimeter of the square is 3 times the perimete

bija089 [108]

Here's the solution :

Side of the equilateral triangle = x

Side of square = x + 10

perimeter of equilateral triangle = 3 × x = 3x

perimeter of square = 4 × (x + 10)

now, according to above statement :

permission (square) = 3 × perimeter (triangle)

that is :

$4(x + 10) = 3 \times 3x$

$4x + 40 = 9x$

$9x - 4x = 40$

$5x = 40$

$x = 8$

therefore, side of triangle = 8 cm

perimeter (triangle) = 8 × 3 = 24 cm

side of square = 8 + 10 = 18 cm

perimeter of square= 18 × 4 = 72 xm

Answer:

A) $m=\frac{350}{25}$

Step-by-step explanation:

We are trying to find how long it will take Carlos to have $500 TOTAL, so we need to subtract what he already has ($150) to get the value we want to divide by $25 to figure out how many months it will take him to save up the rest. The given answer above is just a simplified way of writing $m=\frac{500-150}{25}$ , if that makes more sense.
