So if Beth ran the 400 meter dash in 57.2 seconds, and that time was 2.4 seconds faster than her previous time, she would have run a 59.6 second previous time. The equation would be X (current time) + Y (time difference) = Z (Previous time) we can see that her current time is 57.2 seconds, so that would replace X. We now have 57.2+Y=Z. So we can see in the problem that it was 2.4 seconds faster, so that’s the time difference. Our new equation is 57.2+2.4=Z. Now all we have to do is add 57.2 and 2.4 and you get her previous time, which is 59.6 seconds. Hope this helped! :D
Answer:
W = 210
Step-by-step explanation:
What is 35% of 600
Is means equals and of means multiply
W = 35% *600
Changing the percent to a decimal
W = .35 *600
W = 210
Each number goes up by 3. 13-10=6, 19-13=9, 40-28=12, etc. The next number would be 40+15=55
Answer:
1. equation: y = 7x, missing = 35
2. equation: y = x - 5, missing = 1
3. equation: y = 1/2x, missing = 2
4. equation: y = x + 4, missing = 15
Step-by-step explanation:
Equation Format: y = mx + b
<h2>1.</h2>
(m) Slope = 
= 7
14 = 7(2) + b
14 = 14 + b
b = 0
y = 7x + 0
Solve for the missing y:
y = 7(5) + 0
y = 35 + 0
y = 35
-Chetan K
Answer:
A) 1/5
Step-by-step explanation:
Points on the graph: (10, 2) and (20, 4)
Slope:
m=(y2-y1)/(x2-x1)
m=(4-2)/(20-10)
m= 2/10
m = 1/5
