Answer:
1st answer BD should be the right one because BD bisects angle ABC
Answer:
1. is 275 divided by 5 equals 55 so 55 times 12=660
2. 24 hours in a day that's 6 minutes a day 18 minutes in 72 hours
Step-by-step explanation:
=3.0625/ 1
=30625/10000
(multiply top until the decimal goes. and have to multiply by the same number bottom also, here have multiplied by 10000 both bottom and top)
=6125/ 2000
=49/16 (simplify the both bottom and top)
Answer:
D 4/10 = 2/x
Step-by-step explanation:
2/x represents the ratio of the man's height to the tree's height. The appropriate proportion will be one that ratios the man's shadow (4 m) to the tree's shadow (6+4=10 m).
The correct proportion is ...
4/10 = 2/x
Answer:
4x - 7y = 19
4(-4) - 7(-5) = 19
-16 - (-35) = 19
-16 + 35 = 19
19 = 19
(-4,-5) is a solution to given equation.
4(9) - 7(6) = 19
36 - 42 = 19
-6 ≠ 19
(9,6) is not a solution to given equation.
4(1) - 7(-3) = 19
4 - (-21) = 19
4 + 21 = 19
25 ≠ 19
(1, -3) is not a solution to given equation.
4(-6) - 7(2) = 19
-24 - 14 = 19
-38 ≠ 19
(-6,2) is not a solution to given equation.
