Answer:
Children= 108
Adults= 170
Step-by-step explanation:
<u>First, we structure the two equations:</u>
x= number of tickets for children
y= number of tickets for adults
3.25x + 5y= 1,201
x + y= 278
<u>Now, we isolate x in one equation and substitute in the second one:</u>
x= 278 - y
3.25*(278 - y) + 5y= 1,201
903.5 +1.75y = 1,201
y= 297.5/1.75
y= 170
<u>Finally, we determine the value of x:</u>
x= 278 - 170
x= 108
<u>Prove:</u>
3.25*108 + 5*170= 1,201
170 + 108= 278
Answer:
n + 7 <= 15 or, n + 7 is less than or equal to 15
Answer:
24x^2+78x-60
Step-by-step explanation:
−3(4x + 5)(2x + 4)
-3(4x)+(-3*5)= -12x+-15
(-12x+-15)(2x + 4)
F- -24x^2
o- -48x
i- -30x
l- -60
24x^2+78x-60
I’m pretty sure that is B because friday is 4 times more than monday.
Answer:
x=0;y=-2
Step-by-step explanation:
multiply first equation by 6: 18x-24y=48
Subtract 2nd equation from 1st: -19y=38
y=-2
Sub into 1st equation: 3x-4(-2)=8
3x+8=8
3x=0
Therefore, x=0;y=-2
