Answer: she has spent $60 dollars and she has 180 more to go
Step-by-step explanation:
Answer:-2.75 x = -233.75
/ -2.75
x = 85.00
plug value of x in (1)
1.00 x + 1.00 y = 150.00
85.00 + y = 150.00
y = 150.00 -85.00
y = 65.00
y = 65.00
x= 85 number of child tickets
y= 65 number of adult tickets
Step-by-step explanation:x= number of child tickets
y= number of adult tickets
Total sold
1.00 x + 1.00 y = 150.00 .............1
Total value
4.75 x + 7.50 y = 891.25 .............2
Eliminate y
multiply (1)by -7.50
Multiply (2) by 1.00
-7.50 x -7.50 y = -1125.00
4.75 x + 7.50 y = 891.25
Answer:
t=0 t = -10/3
Step-by-step explanation:
5|3t+5|=25
Divide each side by 5
5|3t+5| /5=25/5
|3t+5|=5
Now to get rid of the absolute value we get two equations, one positive and one negative
3t+5 =5 3t+5 = -5
Subtract 5 from each side
3t+5-5 =5-5 3t+5-5 = -5-5
3t =0 3t = -10
Divide by 3
3t/3 = 0/3 3t/3 = -10/3
t=0 t = -10/3
