Answer:
C (let me know if I am wrong!)
Step-by-step explanation:
We need to solve the equation.
If 5x+y = -24, then -24 - 5x = y.
x+ 3(-24-5x) = -2
= -14x-72=-2
= -14x-72+72=-2+72
= -14x=70
= -5
If x = -5, then -5 + 3y = -2.
3y = -2+5
3y = 3
y=1
So the answer is C.
X/y = 2 so x = 2y
z/x = 4 so z = 4x but x = 2y so z = 4(2y) = 8y
now you have
x = 2y, z = 8y
x + y + z 2y + y + 8y 11y 11
------------ = -----------------------= ------------- = ----------- = 5 1/2
x 2y 2y 2
answer
C. 5 1/2
<span>m = 4a + 2c
a = 25; c = 5
Replace a with 25. Replace c with 5.
Then evaluate the expression.
m = 4 * 25 + 2 * 5
m = 100 + 10
m = 110
Answer: 110 meatballs are needed.</span>
Answer:
1.length = 15, width = 12, height = 13
2. 13 × 12 × 15 = 2340
Step-by-step explanation:
3 ÷ 1/4 = 12
3 3/4 = 15/4
15/4 ÷ 1/4 = 15
3 1/4 ÷ 1/4 = 13
length = 15
width = 12
height = 13
13 × 12 × 15 = 2340
L=k/r^2,
r^2 is the denominator cause L varies inversely with the square of distance
The answer is B
