3) 2 - 8x + 3x When x = 5
4) 4 - 2x + 5x when x= 4
5) z divided 2 - 4z + 3(z-3) when z =8
GEMDAS!
1:
3 - 7 x 5 + 2 x 4
3 - 35 + 2 x 4
3 - 35 + 8
3 - 27
-24
2:
7 - 2 x 5 + 9 x 3
7 - 10 + 9 x 3
7 - 10 + 27
7 + 17
24
3:
2 - 8x + 3x When x = 5
2 - 8(5) + 3(5)
2 - 40 + 15
2 - 25
-23
4:
4 - 2x + 5x when x= 4
4 - 2(4) + 5(4)
4 - 8 + 20
4 + 12
16
5:
z ÷ 2 - 4z + 3(z - 3) when z = 8
8 ÷ 2 - 4(8) + 3(8 - 3)
8 ÷ 2 - 32 + 24 - 9
4 - 32 + 24 - 9
4 - 8 - 9

Answer: 55/17
Step-by-step explanation: To write a mixed number as an improper fraction, first multiply the denominator by the whole number, then add the numerator.
So here we multiply the denominator (17) by the whole number (3), then we add the numerator which is 4.
Finally, we put our new number over our old denominator and we have our answer 55/17.
Therefore, 3 and 4/17 can be rewritten as the improper fraction 55/17.
to find how many dollars per hour, you must choose one ratio of dollars to hours
24:3
we want to get 3 to 1 so we must divide both numbers by 3
now our new ratio is
8:1
the unit rate is
$8 per hour
