Answer:
110
Step-by-step explanation:
Set hamburgers<em> </em>as <em>h,</em>
salted pretzels as <em>p</em>,
hot dogs as <em>d.</em>
h+p+d=144
(3.00)h+(2.25)p+(2.00)d=354.25
=>3h+2.25p+2d=354.25
we also know (2.00)d=82 => d=41
We make 3h+2.25p+2d=354.25 => 3h+2.25p=272.25
and h+p+d=144 => h+p=103
Set h=p-103
Substitution
3(p-103)+2.25p=272.25
3p-309+2.25p=272.25
(5.25)p=581.25
p=581.25/5.25=110.7142857
We round down =>110.
N + 7 > (or equal to) 53 is the answer
Answer:
2.99
Step-by-step explanation:The hundredth is the second number after the decimal. it gets rounded up because 5 makes it go up and the answer becomes 2.99
The first step would be to isolate the square root on the left side. √x-6+2 = 6 √x-6 = -2+6 √x-6 = 4We would have to take away the radical on the left and square the equation. (√x-6)2 = (4)2 x-6 = 16Finally, x -22 = 0 x = 22
