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.
Answer:
Equation: -5 + 12
Overall change: 7 yards
Step-by-step explanation:
In the problem, it says "lost 5 yards". "Lost" is another way of saying subtraction or negative. Therefore, our starting number is -5.
The problem also says "gained 12 yards". "Gained" is another was of saying addition or positive. Therefore, our second number is positive 12.
Together, these two numbers look like this: -5 + 12. To add them, go 12 to the right of -5 if on a number line. That would be like this: -5, -4, -3, -2, -1, 0, etc until you get to 7 which should be 12 more than -5.
Therefore, the answer is 7 yards.
Step-by-step explanation:
2/x + 3 = 1/x
2/x - 1/x = -3
1/x = -3
1 = -3x
x = 1/(-3) = -1/3
Answer:
x= 3
y=2
Step-by-step explanation:
Let's solve your equation step-by-step.
2=4x−10
Step 1: Flip the equation.
4x−10=2
Step 2: Add 10 to both sides.
4x−10+10=2+10
4x=12
Step 3: Divide both sides by 4.
4x/4=12/4
x=3
