three times the sum of a number and 4 is 8 less then one-half the number .write and solve an equation to find the number

Answers

3(x + 4) = x/2 - 8

First, we can multiply both sides by 2:

6(x+4) = x - 16

6x + 24 = x - 16

Isolate x:

5x = -16 - 24

5x = -30

x = -6

45 is 15% of what number

Answers

45 = 15% of number
45 = 15% × n
15% = $(15)/(100)$ = 0.15

45 = 0.15n

$(45)/(0.15)$ = $(0.15n)/(0.15)$
0.15 and 0.15 cancels out

300 = n

15% of 300 is 45

45 is 155 of 300

15% of a number is 45
15% × x = 45
x = 45 ÷ 15%
x = 45 ÷ 15/100
x = 45 × 100/15
x = 4500/15
x = 300

Check:
15% × 300
= 15/100 × 300
= 15 × 3
= 45

45 is 15% of 300.
