Answer:
15
Step-by-step explanation:
3x - 2y = ?
3(7) - 2(3) = ?
21 - 6 = ?
= 15
All you have to do is substitute the given values & follow the order of operations! Best of luck.
Part 1:the answer is 1/36
each time we roll the dice, the whole probabilities are 6
if we roll it two times
6*6=36
part 2
it's 1/8
each time we flip a coin, the whole probabilities are 2
if we flip it 3 times
2*2*2=8
good luck
Step-by-step explanation:
you have the formula and the numbers. just calculate !
cost of membership
y = 100 - 0.02x
a)
for x = 2600
y = 100 - 0.02×2600 = 100 - 52 = $48
b)
the reduction element of the cost of membership is the
"- 0.02x" part.
we want to refuse the membership costs by $41, so
0.02x = 41
x = 41/0.02 = $2,050
c)
the same as b)
just now the membership costs need to be reduced to 0.
so, that means we need to reduce by $100 !
0.02x = 100
x = 100/0.02 = $5,000
That is an isosceles right triangle. (Also known as a 45 45 90 triangle).
Answer:
C
Step-by-step explanation:
the distance is 15•6 = 18•5 = 90 feet
so, time needed = 90/30 = 3 second
