4y-17=43
move -17 to the other side
sign changes from -17 to +17
4y-17+17=43+17
4y=43+17
4y=60
divide both sides by 4 to get y by itself
4y/4=60/4
answer:
y=15
Answer:
x = 55°
Step-by-step explanation:
From given figure we have
Two lines parallel
As we know simple straight line maintain an angle of 180°
Third line bisecting the two parallel lines at different position
But hold same same angle form both because lines are parallel.
To find angle = 180 - 125 = 55
5y^2 - 4y - 14 is the correct answer.
Answer:
y = -2x + 10
Step-by-step explanation:
8x + 4y = 40
4y = -8x + 40
y = -2x + 10
Let the number of marbles be M,
then,
M=6a+4 (when shared among 6 students)
M=7b+4 (when shared among 7 students)
M=8a+4 (when shared among 8 students)
thus
M-4=6a
M-4=7b
M-4=8c
That is M-4 is the smallest number which is a multiple of 6, 7 and 8
Thus we need to find the LCM(6, 7, 8)
LCM(6, 7, 8)=LCM(2*3, 7, 2*2*2) = 2*2*2*3*7=8*21=168
The smallest M-4 is 168,
so the smallest M is 168+4=172
Answer: 172
