Answer:
12
Step-by-step explanation:
4-2x=-18
-4 -4
-2x=-24
-2 -2
x=12
Step-by-step explanation:
the slope is the ratio "y coordinate difference / x coordinate difference".
so,
(2 - 6) / (x - 2) = 4/7
-4 / (x - 2) = 4/7
-1 / (x - 2) = 1/7
-1 / (x - 2) = 1 / -(x - 2) = 1/7
-(x - 2) = 7
-x + 2 = 7
-x = 5
x = -5
so, the point is (-5, 2)
1.
A. This statement is wrong because the prediction is valid, not valid.
B. Refer to A.
C.This statement is valid, yet explains the prediction incorrectly.
[D.] This statement is correct because 50 x 6 = 300, therefore 20% of 300 is 60.
2.
A. This is incorrect because it equals 125%
B. This is also incorrect, it equals 12.5%
C. Refer to B
[D.] This is correct, it equals 1.14%, which is less than 1.25%
Answer:
8:19
Step-by-step explanation:
Ball B: diameter in mm = 9.5 * 10 = 95 mm
Ratio of Ball A to Ball B = 40 : 95
= 8:19 answer
