Answer:
1) 18
2) 6
3) 12
4) 12
5) 7
6) 9
Step-by-step explanation:
1) 2*x = 6^2, 2x=36, x = 18
2) 2*(x+2) = 4^2, 2x+4 = 16, x = 6
3) 10^2 = 5 * (x+8), 100 = 5*(x+8), x = 12
4) The altitude is 4sqrt3 using pythagorean, (4sqrt3)^2 = 4*x, 48 = 4*x, x=12
5) Altitude is sqrt63 using pythagorean, (sqrt63)^2 = 9x, x = 7
6) Altitude is sqrt72, sqrt(72+9) = 9
Answer:
3x + 8
Step-by-step explanation:
Michele's ages is equivalent to x, or 1x. Then you add Kayla's age to Michele's age which now equals 3x. Finally, you add 8, which is Erica's age.
Answer:
$146
Step-by-step explanation:
54.75= 3 hrs
divide both sides by 3
18.25= 1 hr
multiply both sides by 8
$146= 8hrs
Answer:
C. The x-coordinate should be Three-fourths.
Step-by-step explanation:
Since point A is 0.75 units to the right, it is 3/4 if 4/4 is 100.
The number is 200 .
10 is 5% of 200
