Step-by-step explanation:

I don't have any questions for you to answer but okay.

To find out the percent you just gotta times 980 by 85 and then divide the product by 100:

(980*85)/100=

83,300/100=

833

14.

To find out the percent of calls you need to do this and simplify

= which is 75%

15.

If 570 is 3/5 or 60% then you can use ratios to find out the whole number.

3:5

570:x

x would be:

(570/3)*5=

190*5=

950

950 students in all

16.

15.5% of 1240 is just (15.5*1240)/100 which is 192.2

17.

I don't want to explain anymore:

(1500*82)/100=123000/100=1230

18.

(5720*3)/100=17160/100=171.6

19.

21/50= 42%

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
