Answer:
He needs to complete a distance of 4,030 yards around the rink to make a total skating distance of 3 miles
Step-by-step explanation:
In this question, we are asked to calculate the number of yards needed to complete 3 miles skating around a rink.
We proceed as follows;
First, we can see he has skated 5 times around a rink that has a distance of 250 yards. His total distance covered would be 250 * 5 = 1250 yards
Now he is looking at completing 3 miles, we need to know the number of yards in 3 miles.
Mathematically, 1 mile = 1760 yards
3 miles = 3 * 1760 = 5,280 yards
To know the number of yards he need to skate more, we simply carry out a subtraction;
5,280 yards - 1250 yards = 4,030 yards
Answer:
x=24 or 25
Step-by-step explanation:
90% is x=24
89.999999 repeat% is x =25
A. 6n+3n+10= 9n+10. Jordan is 9n+10 years old.
B. 6n+9n+10= 15n+10. The total age of Prince and Jordan is 15n+10.
C. 6n-9. Kimberly is 6n-9 years old.
D. (6n+9n+10)+6n-9 = 15n+10+6n-9 = 15n+6n+10-9 = 21n+1. The total age of Prince, Jordan and Kimberly is 21n+1
E. 21•(4)+1=84+1=85. The total age of Prince, Jordan and Kimberly is 85 years.
Answer:
Step-by-step explanation:
A yard of lace costs w cents a yard and fabric costs $.40 more than the lace. This means that the cost of a yard of fabric would be
w + 0.5
Kimberly wants to buy one yard of lace and 2 yards of fabric. This means that the total amount of money that she would have to pay for the lace is is
0.4 × 1 = 0.40
Amount that she would spend on the fabric is 2(w + 0.5) = 2w + 1
Total cost would be
0.4 + 2w + 1
According to my study B (-4, 1) is the answer
