Answer: x=16
Step-by-step explanation:
28= 8x + 12-7x
28= 8x-7x +12
28= x + 12
-12 -12
16= x
Commercial jet's speed = 2x-162 (plug this in the equation below)
Private jet's speed = x
Equation:
10(x) = 8(2x-162)
10x = 16x - 1296
6x = 1296
x = 216 (Private jet's speed)
Take the first equation and plug x value in;
2x-162
2(216) - 162 = 270 ( Commercial jet's speed)
You would have to use the formula, pi(r^2)*h.
0.5*0.5= 0.25
0.25*3.14=0.785
0.785* 2.5=1.9625
Your answer would be 1.9625

Answer: -1410
Step-by-step explanation:
Let's start by subbing in -4 for x
Now we can solve
Answer:
c)
Step-by-step explanation:
−2 = −⅔[5] + b
−3⅓
1⅓ = b
y = −⅔x + 1⅓
Then convert to Standard Form:
y = −⅔x + 1⅓
+⅔x + ⅔x
__________
⅔x + y = 1⅓ [We do not want fractions in our Standard Equation, so multiply by the denominator to get rid of it.]
3[⅔x + y = 1⅓]
* 1⅓ = 4⁄3
