Answer:
C
Step-by-step explanation:
Given the sides of cubes in the ratio a : b , then
ratio of volumes = a³ : b³
Here ratio of sides = 2 : 4 = 1 : 2 ( smaller : larger ) , so
ratio of volumes = 1³ : 2³ = 1 : 8
Then the volume of the larger cube is 8 times the volume of the smaller.
1.
( x - 5 ) / x - 1 = ( x + 3 ) / x / · x ( we will multiply both sides by x )
x - 5 - x = x + 3
- x = 3 + 8
- x = 8
x = - 8
Answer: D ) 8
2.
2/(8 x²) = 1/ 8 x / · x
2 / 8 x = 1 / 8
8 x = 16
x = 16 : 8
x = 2
Answer: D ) 2
3.
( x + 4 )/ x + 1 = ( x + 6 ) / x / · x
x + 4 + x = x + 6
x = 6 - 4
x = 2
Answer: B ) 2
4.
1 / 6 = 3 / ( x + 12 )
x + 12 = 18
x = 18 - 12
x = 6
Answer: A ) 6
Answer: $1.83
Step-by-step explanation:
1. Solve this problem: 1+2+4+6+8+10+12+14+16+18+20+22+24+26. There are 15 numbers for 15 days. You want to solve this because each day is doubled. For example: first day is 1 cent, second day is 2 cents, third day is 4 cents, and so on.
2. Answer is 183 cents.
3. Convert 183 cents to dollars.
4. Your answer is $1.83.

Answer:
x = -6, y = 12
Step-by-step explanation:
Equations:
y = 2x + 24
y = -2x
Bring the the equation together and add like terms together:
-2x = 2x + 24
-4x = 24
Divide both sides by -4 to isolate x:
Find y:
y = -2(-6)
y = 12
Verify:
12 =2(-6) + 12
