Answer:
43
Step-by-step explanation:
3x + 10 = 5x - 12
10 = 2x - 12
22 = 2x
x = 11
check:
33 + 10 = 55 - 12
43 = 43
correct
x = 11 so bring this into 3x + 10
we get 43
Answer:
Equations:
y + 10x = 23
y + 15x = 33
cost of basket with 25 apples = $53
Step-by-step explanation:
A basket with 10 apples cost $23 and a basket with 15 apples cost $33. Note that these costs also include the cost of the basket, which is same in both case. Let the cost of empty basket with "y" and cost of each apple be "x"
Cost of basket and 10 apples is $23. We can transform this statement into an equation as:
y + 10x = 23 Equation 1
Similarly,
Cost of basket and 15 apples is $33. This gives us another equation:
y + 15x = 33 Equation 2
Subtracting Equation 1 from Equation 2 , we get:
y + 15x - (y +10x) = 33 - 23
5x = 10
x = 2
Using the value of x in equation 1, we get:
y + 10(2)= 23
y = 23 - 20
y = 3
This means, cost of basket is $3 and cost of each apple is $2.
Now we can calculate the cost of basket with 25 apples, which will be:
Cost of basket + Cost of 25 apples = Total Cost
3 + 25(2) = 3 + 50 = $53
Answer:
1. y = 2x-4
2 y = -1/2x+3
Step-by-step explanation:
Slope intercept form of the equation is y= mx+b
where m is the slope and b is the y intercept
1. y- 2x = -4
We need to solve for y
Add 2x to each side
y -2x+2x = 2x-4
y = 2x-4
2 y-3 = -1/2 x
We need to add 3 to each side
y-3+3 = -1/2x +3
y = -1/2x+3
