Translate the percent word problem in a equation: If 5 is increased to 8, the increase is what percent of the original number?
-Dominant- [34]
If you increased 5 to 10, then I would have doubled the number 5 and this is a 100% increases.
If you increased 5 to 7.5, then this is 50% increase, because 50% of 5 is 2.5 and 5 + 2.5 = 7.5
If you increased 5 to 6, then this is a 20% increase,because 5 + 1 = 6 and 1 is 20% of 5
If you increased 5 to 7, then this is a 40% increase,because 5 increased by 2, 5 + 2 = 7, and 2/5 = 40%
If you increased 5 to x, then 5 was increased by x/5×100%
For example 5 to 9 is a4/5×100%=80% increase

So here 5 increases by 8, 5 + 3 = 8, thus the percentage increase is3/5×100%=0.006

Is 0.07 less than 0.06
Kobotan [32]
No, .007 is not less than .006. Not only is the decimal form evidence of these integers, but writing them as a percentage can also decipher the question.

Since .007 equals to 7% (0.07 = 7/100) and 0.06 equals to 6% (0.06 = 6/100) then 7% is greater than 6%, therefore, answering you question.

Help please thank you and also show the work please
ziro4ka [17]

Answer:

y= -1.4x-6.6

Step-by-step explanation:

(1,-8)

7x+5y=-7

Make the equation into standard form

Subtract 7x from both sides

5y=-7x-7

Divide all by 5

y=-1.4x-1.4

Since they are parrallel, we know the slope is -1.4x

y=-1.4x+b

(1,-8) is one of the points it goes through

Replace the x and y in the equation for the x and y in the incomplete equation

-8=-1.4+b

Add 1.4 to both sides

-6.6=b

Thus the equation is

y=-1.4x-6.6

The table below shows two equations:
VMariaS [17]
| 3x - 1 | + 7 = 2
| 3x - 1 | = 2 - 7
| 3x - 1 | = -5.....no solution because an absolute value cannot equal a negative number.

| 2x + 1 | + 4 = 3
| 2x + 1 | = 3 - 4
|2x + 1 | = -1...same thing...no solution..cannot equal a neg. number

so Eq. 1 and Eq. 2 both have NO SOLUTIONS :)
