Answer:
a=3/5 or 0.6
Step-by-step explanation:
a-8/5-2/3a=-7/5
Step 1: Multiply both sides
15a-24-10a=-21
Step 2: Combine like terms
5a-24=-21
Step 3: Calculate and divide both sides by 5
5a=3
Solution:
a=3/5 or 0.6
Answer:
y = -x+3
Step-by-step explanation:
Slope intercept form => y = mx+b
To find 'm', the slope, pick 2 coordinates.
(0,3)
(2,1)
Use this equation to find the slope using these 2 coordinates: (y1 - y2)/(x1 - x2)
(3 - 1)/(0 - 2) = -1
m = slope = -1
'b' is the y-intersept, or the point when a line passes through the y-axis. That's (0,3).
b = y-intercept = 3
<em>So the equation will be y = -1x + 3, or y = -x + 3</em>
Answer:
x = 4.2
Step-by-step explanation:
72 + 10x = 114
10x = 114 - 72
10x = 42
x = 42/10
x = 4.2
Answer:
It will take 12 and 30 hours
Step-by-step explanation:
To solve this, you need to divide by <u>distance needed to travel by the speed</u>
600/48 is equal to 12.5 hours.
.5 hours is equal to 30 mins because 60mins times .5 is 30 minutes, therefore <u>the final answer is 12.5 hours</u>
I hope this helps :)
The group rent 11 river rent tubes and 4 cooler tubes.
Step-by-step explanation:
Rent for river rent tube = $20
Rent for cooler tubes = $12.50
Total spent = $270
Total tubes rented = 15
Let,
x be the number of river rent tube.
y be the number of cooler tubes.
According to given statement;
x+y=15 Eqn 1
20x+12.50y=270 Eqn 2
Multiplying Eqn 1 by 20

Subtracting Eqn 2 from Eqn 3

Dividing both sides by 7.5

Putting y=4 in Eqn 1

The group rent 11 river rent tubes and 4 cooler tubes.
