The y is going to be 165 if the x is 54 because you need to multiply by 3 each time.
2 5/7 as a decimal is approximately 2.70
We know that the ones place will be a two. That doesn’t change when you convert. Next you need to divide 100 by 7, which equals 14. Then you need to do 14 times 5, which equals 70. So, now you know the values after the decimal point (.70). Combine that with the whole number 2 to get 2.70.
Answer:
20 people
Step-by-step explanation:
Let x be the number of people initially. We can find the amount each of them has to pay at first
2 / x
But when 10 people walk away, the remaining (x - 10) has to pay 10 cents more to get the same total of $2. This would means
From here we can perform cross multiplication
Multiply both sides by 10x:
x = 20 or x = -10
Since x can only be positive we will pick x = 20
Answer:
for 20 the answer is B
Step-by-step explanation:
Answer:
RQ = 9.
Step-by-step explanation:
m < RPQ = 180 - 90 - 75 = 15 degrees
m < PQM = 75 - 60 = 15 degrees.
So triangle PMQ is isosceles so side PM is congruent to side MQ, therefore MQ = 18.
Triangle RQM is a 30-60-90 triangle with RQ the shortest leg (because it is opposite the lowest angle) so that makes RQ = 1/2 of MQ. (The sides in a 30-60-90 triangle are in the ratio 1:sqrt3:2)
RQ = 1/2 * 18 = 9.
