Answer:
Rosaria purchased 50 bracelets and 70 necklaces
Step-by-step explanation:
Let the number of bracelets be b and the number of necklaces be n
b + n = 120 •••••(i)
Secondly;
10b + 11n = 1270 ••••(ii)
Total cost of b bracelets at 10 per 1 is 10b
Total cost of n bracelets at 11 per 1 is 11n
Adding both gives 1270
From i, b = 120-n
Substitute this into ii
10(120-n) + 11n = 1270
1200 - 10n + 11n = 1270
n = 1270-1200
n = 70
b = 120-n
b = 120-70
b = 50
40 Why? 80%x X=50 or 80/100x X=50
The answer choice is B I just took
Your answer is a equation!
Answer:
0.125
0.125x = Distance Traveled in Miles
0.125 * 11 = 1.375 Miles Ran
Step-by-step explanation:
First divide 1 mile by 8 minutes
1 mi / 8 min = 0.125 mi
Then you simply show 0.125 * x (x being the number you insert to find the distance) = How far you ran
0.125x = Distance Traveled in Miles
Finally you insert 11 for x and multiply to find the distance
0.125 * 11 = 1.375 Miles Ran
