Answer:
A
Step-by-step explanation:
So we want to convert 59°F to Celsius using the given formula:
Thus, substitute F for 59:
Subtract:
Simplify:
The answer is A
F + 2b = 92
3b + 4f = 212
———————————
You didn’t say you need them solved, but just in case:
f = 92 -2b
3b + 4(92-2b) = 212
3b + 368 -8b = 212
-5b = -156
b = 31.20
f + 2(31.20) = 92
f + 62.4 = 92
f = 29.60
3(31.2) + 4(29.6) = 93.6 + 118.4 = 212
Answer:
(-4, -2).
Step-by-step explanation:
Compare y = (1/2)(x + 4)^2 – 2 to the standard equation:
y = a(x - h)^2 + k whose vertex is at (h, k).
We see that h = -4 and k = -2. Thus, the vertex of the vertex of the given parabola are (-4, -2).
We know that,
Number of scouts = 15
Number of feathers required by each scout = 18
Hence, Total Number of feathers required = 15 * 18 = 270
We also know that Number of feathers in each bag = 12
Hence, number of bags required to decorate picture frames = Total number of feathers required ÷ number of feathers in each bag
⇒ Number of bags required to decorate picture frames = 270 ÷ 12
⇒ Number of bags required to decorate picture frames = 22.5
Since half a bag can't be bought 23 bags would be required.
18x-24+2x
20x-24
You simply multiply the 6 with everything in the fraction and the add the 2 x to it.
