30% First find the difference between the two (58.50-45) then divide the difference by the original (13.5/45) and that will give you .30 to make it a percent move the decimal two places to the right :)

Sushilis now 4 times as old as Sunil. 5 years ago Sushilwas 7 times as old as Sunil was then. Find the present ages of each of t
Illusion [34]

Answer:

Sunil = 10 and Sushil= 40

Step-by-step explanation:

Present ages-

Sushil= 4x

Sunil= x

5 years ago-

Sushil = 4x - 5

Sunil = x - 5

4x - 5 = 7(x - 5) = 4x - 5 = 7x - 35

                        = -5 = 3x - 35

                        = 30 = 3x

                        = 10 = x

So substitute the xs for 10-

Present Sushil= 4 x 10 = 40

Present Sunil= 10

Give an example of an addition problem in which you would and would not group the addends differently to add
madam [21]
<span>Changing the grouping of the addends should not change the sum, according to the associative property of addition. You might group them differently with (50 + 3) + 47, so that you have 50 + (3 + 47). You might not regroup them with (16 + 4) + 5 rather than 16 + (4 + 5).</span>

Can someone help me with these last four please please! (24 points)
Vesnalui [34]
For #30 I ended up doing a lot of adding & if I’m correct it would take about 3 to 3 & 1/2 years for Marshall & Jim to end up with the same salary. So if I’m correct the equation would be the salary + the raise. So it would be something like s + r =x. X equals the total amount of the salary + the raise put together.
For #32 I wrote it down multiple times to make sure I get it right. I ended coming up with 46<-8x8<-6x. I tried figuring out the answer to that but I didn’t understand so I went on Socratic & it said there was no solution. Yeah
Sorry I couldn’t help with the other 2. I tried my best here.
