Answer:
I think it's D
Step-by-step explanation:
Supplementary means the angels add up to 180 degrees. So 95 + ? = 180. The ? is equal to 85, but how do you get it. Well we know 5x means to multiply a # by 5. So 17 x 5 = 85. So x = 17. Hope this helps!
Answer:
C
Step-by-step explanation:
Direct variation is a special case of first order equations; in both cases, the input is multiplied by a constant which we call the "slope" or "constant of variation." However, no direct variation equation includes a constant ("y-intercept"). So, if a given equation does have a y-intersect, that equation does not represent direct variation; if it does NOT have a y-intercept, that equation represents direct variation.
A) involves a constant term, -2; NOT direct variation
B) involves a constant term, 10; NOT direct variation
C) Here 3y = x, or y = x/3, involves no constant term, so Does represent direct variation
D) involves a constant term -3; NOT direct variation
Answer:
A.) 96 ft/sec
Step-by-step explanation:
to find the average speed of the watermelon's fall in 6 seconds, substitute 6 as t in the equation and then divide by 6: 
If each spoke reaches from the center of the wheel to its rim, then that means that each spoke is as long as the radius.
To calculate radius:
C=2πr
π=3.14
C=42 inches
42=2(3.14)r
2*3.14=6.28
42=6.28r
Divide 42 by 6.28
42/6.28=6.68
length of each spoke is 6.68 inches.
D=3 is the answer for this equation
