A. They are both proportional because they have the same ratio.
b. The two graphs are the same because they have a constant rate of change (50), but they have different y-intercepts.
65 millimeters to meters is .065 and you would know this because there's .001 millimeters in 1 meter so with 65 you would move the decimal up 3 spaces o make .065m
5ax+2a=9a
5ax+2a-2a=9a-2a
5ax =7a
5ax/5a =7a/5a
x=7/5
Answer:
To thirds if I'm not wrong
Step-by-step explanation:
three fourths meaning 3/4 of a number is 1/2
so:
3/4 of number is 1/2
1/4 of number = number ÷ 4
3/4 of number = (number ÷ 4) × 3
(number ÷ 4) × 3 = 1/2
<divide both sides by 3>
number ÷ 4 = 1/6
<multiply both sides by 4>
number = 4/6
<show in lowest term>
number = 2/3
the number is 2/3
Aaron: 166 times in 120 seconds, or 83 times in 60 seconds
Callie; 88 times in 60 seconds
Emma: 48 times in 30 seconds, or 96 times in 60 seconds
Galen: 22 times in 15 seconds, or 88 times in 60 seconds
Callie's and Galen's heart rates are equivalent.
