Solve this question? 7x - 3x +7 =3 (x - 4)+20

Answers

Answer 1

Answer: x=1

To solve this you start by adding like terms on the left side and doing the distributive property and adding like terms on the right. This would get you
4x+7=3x+8

Then you minus 3x on both sides getting
x+7=8

Then subtract 7 from both sides getting x=1.

Answer 2

Answer: 7x - 3x + 7 = 3 ( x - 4 ) +20
⇔ 4x + 7 = 3x - 12 + 20
⇔ 4x - 3x = 8 - 7
⇔ x = 1

Answers

If you would like to solve the equation y/9 + 5 = 0, you can do this using the following steps:

y/9 + 5 = 0
y/9 = -5 /*9
y = -5 * 9
y = - 45

The correct result would be D. y = - 45.

Jen bought some bagels the ratio of the numbers of sesame beagles to the number of plain bagels the she bought is 1:3 find the decimal equivalent of the prrcent of the bagels that are plain

Answers

If the number of sesame to plain bagels is 1:3, that means that for every 3 plain bagels, there is 1 sesame bagel. So if there were 4 bagels total, with 3 being plain and 1 being sesame, then the fraction of the total amount of bagels represented by the amount of plain bagels there are would be 3/4.
3/4 written as a decimal would be 0.75, or 75%.
