So 3 bus tickets 3(64) = $192
and 4 train tickets 4(82) =$328
add them together 192+328 =520
it would cost $520 to buy 3 bus tickets and 4 train tickets
Answer:
x < 1
Step-by-step explanation:
2(x-7)<-12
Divide by 2
2(x-7)/2<-12/2
x-7 < -6
Add 7 to each side
x-7+7 < -6+7
x < 1
Answer:
C) $877.50
Step-by-step explanation:
Time t = 4 years
Principal, p = $750
rate, r = 4.25% = 0.0425
Amount that will be in her account in four years =
Simple interest (prt/100) + principal
750 * 4.25* 4 / 100 + 750
127.5 + 750
= $877.50
Answer:
XY = 8 and YZ = 20
Step-by-step explanation:
If XY and YZ are on the one line, we can write
XY + YZ = 28
(2x+2) + (9x - 7) = 28
2x+2 + 9x - 7 = 28
11x - 5 = 28
11x = 33
x = 3
XY = 2x+2 = 2*3 + 2 = 8
YZ = 9x - 7 = 9*3 - 7 = 27 - 7 = 20
Answer:
C: X <= 7
Step-by-step explanation:
Reimagine the inequality as
3 - 1 >= X - 5/7*X
2 >= 2/7*X
1 >= 1/7 * X
7 >= X
