Answer:
Step-by-step explanation:
1,8
5,7
2,3
12. Make equation and plug in
13. Proportion
14. Finding a constant rate, and then manipulate
12. Where x is miles driven, and y is answer, and z is days
19.95z+0.15x=y
Plug in two values
19.95 x 2 + 0.15 x 250 = y
39.93+37.5 = y
y=77.43
13. 5:2 as 175:x
5/2 = 175/x
x = 70
70+175=245
14. 260:5 = x:1
260/5=x/1
x = 52
52:1 = y:9
52/1 = y/9
y = 468
I hope you understand the process.
Answer:
This means that Alex answered 14 questions correctly
Step-by-step explanation:
<u>Step 1: Find an equation</u>
20 * 0.7 = x
<u>Step 2: Multiply</u>
20 * 0.7 = x
14 = x
Answer: This means that Alex answered 14 questions correctly
Y=9x because if you divided y by x all the numbers will equal to 9 which is proportional
Dividing thirty-two by five we get
x=32/5
=6•4
