Answer:
x=9
Step-by-step explanation:
the large triangle is 3 times bigger so the means that 2x+6=24
then you just solve that and x=9
The correct answer is B, because 65+0.20x140=93. You must multiply 0.20 times 140 first, and get 28 and than add 28+65=93.
t + 7 = 21
---Subtract 7 from both sides
t + 7 - 7 = 21 - 7
t = 14
Hope this helps!! :)
Answer:
$24.50 per each adult ticket
Step-by-step explanation:
$15.50*4=$62
$111.00-62=$49
$49/2=$24.50
For every adult ticket they pay $24.50
We have 4(x^2 - 2x + 4) - 7 = 4x^2 - 8x + 16 - 7 = 4x^2 - 8x + 9;
So, 4x^2 - 8x + 9 = <span>ax^2+bx+c
;
The value of b is -8.</span>
