Answer:
6chocolates
Step-by-step explanation:
Given
The total number of chocolate = 15chocolates
If it is divide into ratio 2:3
total ratio = 2+3
Total ratio = 5
Number of chocolate raju receives = 2/5 * 15
Number of chocolate raju receives = 2 * 3
Number of chocolate raju receives = 6chocolates
<span>x - 8y = 46.5
x - 13y = 39.0
subtract the equations to solve for y
5 y = 46.5 - 39
y = 1.5 so he saves 1.5 seconds per step he runs.
sub in y to solve for x
x - 8 (1.5) = 46.5
x - 12 = 46.5
x = 58.5 seconds </span>
Answer:
m=-4
Step-by-step explanation:
5m-10m=-10m+5m=-(10m-5m)=-5m=20
divide by 5 on both sides, -m=4
miltiply by -1 on both sides, m=-4
Inequality: 21d+25≤115
Jim can rent a car for maximum 4 days, therefore, he is not correct in his calculations.
Step-by-step explanation:
Given,
Per day rent = $21.00
Per mile rent = $0.10
Miles to be driven by Jim = 250
Cost of 250 miles = 250*0.10 = $25
Amount Jim can spend = $115.00
Let,
d represent the number of days.
Per day rent*number of days + cost of 250 miles ≤ Total amount to spend
21d+25≤115
Subtracting 25 from both sides

Dividing both sides by 21

Jim can rent a car for maximum 4 days, therefore, he is not correct in his calculations.

First one:
2x + y = -7-1
2x + x + 10 = -8
3x + 10 = -8
3x = -18
x= -6
