Answer: fries=$3.20, burgers=$5.79
Step-by-step explanation:
(f=fries, b=burger)
21.18=2b+3f
29.56=4b+2f
-2(21.18=2b+3f)
-42.36=-4b-6f
<u>29.56=4b+2f</u>
-12.8=-4f
3.2=f
21.18=2b+3(3.2)
21.18=2b+9.6
-9.6 -9.6
11.58=2b
5.79=b
Answer:
Scott will have to do 44 practices
Let X be the number of yards per practice.
Let P = number of practice Scott needs to do.
Multiply 20 yards by 4 sprints
X = 20yards × 4 sprints = 80 yards
Number of yards he had to sprint per practice will be:
1 mile = 1760 yards
Converting from miles to yards
X = 1760 × 2 miles = 3520 yards
Number of practice,P Scott need to do = (3520/80)yards
Number of Practice,P = 44
x= 60
1436
