Answer:
± 5.59
Step-by-step explanation:
We already know the distance and the acceleration, but we're looking for the time.
D = 1/2at²
50 = 1/2 · 3.2t²
50 · 2 = 1/2 · 2 · 3.2t²
100 = 3.2t²
t = ± 5.59
5.59 · 3.2² = 100
14,800=60x+16y
x+y=441
that implies y=441-x so
14,800=60x+16(441-x)
14,800=60x+16*441-16x
14,800-16*441=44x
7744=44x
x=176 kids and 441-176 adults
The error is the sign of Inequality.
For Inequality, when the variable has negative coefficient, moving to another side would cause the Inequality symbol/sign to swap.
Therefore, from x>=-3 as it should be x<=-3
Answer:
The dryer costs $350
Step-by-step explanation:
<u>Step 1: Make a system of equations</u>
<em>w + d = 652</em>
<em>w = d - 48</em>
<em />
<u>Step 2: Plug in the know w into the first equation</u>
d - 48 + d = 652
2d - 48 + 48 = 652 + 48
2d / 2 = 700 / 2
<em>d = 350</em>

Answer: The dryer costs $350
She has 5 ounces of toppings.
The reasoning is you first do 5-2.75 because you must subtract the basic sandwich from the total cost. Then, you must divided 2.25/0.45 because that is the cost of the remaining toppings.
