X is the running time for movie A and y the running time for movie B
X = 2y + 33
3y - × = 57
x- 2y = 33
-× + 3y = 57 => y = 90
=> x 33 + 180 = 213
The correct answer is B. Try it out with the following number: 312, 1893, 255, 344, 232. Two of the or not divisible by 3 by the way.
Answer:
together they have 60
Step-by-step explanation:
B= number of balloons billy has
A =adams balloons
Adam had 30 less balloons than Billy
A = B-30
After Billy gave 5 balloons to Adam, the number of Adam's balloons was half of the number of Billy's balloons.
1/2(B-5) = A+5
1/2 (B-5)-5 =A
set the two equations equal A = B-30 equal to 1/2(B-5)-5 = A
B-30 = 1/2(B-5)-5
add 5 to each side
B-30 + 5 = 1/2 (B-5)
B - 25 = 1/2 ( B-5)
multiply by 2
2(B-25) = 2* 1/2 (B-5)
distribute
2B-50 = B-5
subtract B
2B-50 -B =B-B -5
B-50 = -5
add 50
B-50+50 = -5+50
B = 45
Now we need to find out A
A = B-30
A = 45-30
A = 15
Billy has 45
Adam has 15
together they have 45+15
together they have 60
Answer:
8 / sqrt(3)
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan A = BC / AC
tan 30 = BC / 8
8 tan 30 = BC
8 * sqrt(3)/3 = BC
8/3 sqrt(3) = BC
Answer:
2
Step-by-step explanation:
If it ends in an even number, it is divisible by an even number
Hope this helps!!
