Answer:

x=-7

Step-by-step explanation:

multiply both sides by 10

its gonna be 25x+100=10x-5

subtract 100 from both. 25x=10x-105

subtract 10x from both. 15x= -105

divide both by 15. x=-7

Ed needed to extend the string on his kite. The current string was eight and three fourths feet. He cut a piece of string that m

Pani-rosa [81]

The new length of the string is (13 + 1/4) feet, then the correct option is the last one (counting from the top)

<h3> What is the new length of the string?</h3>

We know that the current string was (8 + 3/4) feet in length. Then they add another piece that measures 4.5 feet.

The new length of the string is given by the addition of the above two lengths, we will get:

L = (8 + 3/4) feet + 4.5 feet

We can rewrite the second length as a mixed number:

4.5 = 4 + 1/2 = 4 + 2/4

Replacing that we get:

L = (8 + 3/4) ft + 4.5 ft

= (8 + 3/4) ft + (4 + 2/4) ft

= (8 + 4) ft + (3/4 + 2/4) ft

= 12ft + 5/4ft = 12ft + (4/4 + 1/4)ft = (13 + 1/4)ft

The new length of the string is (13 + 1/4) feet, then the correct option is the last one (counting from the top).

It would still be 7:2 because when tripled, you triple both numbers, so you get 21: 6, which is the same thing as 7:2, but you just use more. And for ratios, they usually want them to be in simplest form, so it is d) 7:2. The ratio does not change when you triple both sides.

Financial planners recommend that families save about 5% of their take-home pay. Ed and Sherrie save $90 each pay period from th

Ratling [72]

Answer:

Ed and Sheerie save 7.5%.

Step-by-step explanation:

This question can be solved using a rule of three.

Ed and Sherrie save $90 each pay period from their combined paychecks, which total $1200. What percent do Ed and Sherrie save?

How much of $1200 is $90? $1200 is 100% = 1, $90 = x. So

$1200 - 1

$90 - x
