-7 x -3 = 21 that gives you 21 = 5x-24 then you need to add 24 to both sides as it’s negative so 21+24=45. -24+24=0 that gives you 45 =5x. 45/5=9. 5x/5=x. X=9
Answer:
it's B
Step-by-step explanation:
It's definitely B
Using relationship
P(E or F) = P(E)+P(F)-P(E and F)
Substitute
P(E or F)=0.20+0.35-0.10
or
P(E or F)=0.45
8)
3x + 2 = 4x - 3
4x - 3x = 2 +3
x = 5
2y +7 = 4y - 9
4y - 2y = 7+9
2y = 16
y = 2
9)
2x - 2 = x + 2
2x - x = 2+2
x =4
5y - 8 = y+24
5y - y = 24 +8
4y = 32
y = 8
1 mile is equal to 5280 feet
