I think you add the exponents im not sure haven't done it in long time
we know that
1 yard=3 feet
Multiply (89 yards 2 feet) by 14
(89 yards 2 feet)*14=89*14 yards 2*14 feet-------> 1,246 yards 28 feet
convert 28 feet to yards
28 ft=(28/3) yards=9.33 yards
9.33 yards=9 yards+0.33 yards
0.33 yards=1 foot
so
9.33 yards=9 yards+1 foot
substitute
1,246 yards 28 feet=1,246 yards +9 yards+1 foot----->1,255 yards + 1 foot
therefore
<u>the answer is the option</u>
C. 1,255 yards 1 foot
Answer:
The soda costs 2.20 and the sandwich costs 7.70
Step-by-step explanation:
To find this, set the soda cost as x. We now know that the sandwich cost is 3.5x. Add these together and set equal to 9.90
x + 3.5x = 9.90
4.5x = 9.90
x = 2.20
This is the cost of the soda. Now we can multiply that by 3.5 to get the sandwich cost.
3.5 * 2.20 = 7.70
