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
-13
I might've did #5 incorrect.... Really really sorry...
Answer:
sub 5 25 - 5 = 20
-5/2a=20
mult 2 by each side to get rid of fraction
-5a=40
divide -5 from 40
a=-8
Answer:
The answer is 8
Step-by-step explanation:
-5/2 x 8= 20 and if you add 5 it is 25.

Answer:
61
Step-by-step explanation:
1 movie ticket= $12
1 popcorn= $5
x(squared)-5x=0
5x(squared)= 4x
These are all separate equations, can somebody solve them?!
