Answer:
x = 0.5
y = -1/4 or -0.25
Step-by-step explanation:
x + 6y = 2
3x + 2y = 10
Multiply a number by any of the equations to get numbers of the same variable
3x + 18y = 6
3x + 2y = 10
3x - 3x = 0
NB: subtract evenly if u subtract down from top make sure u subtract down from top throughout
16y = -4
16y/16 = -4/16
y = -1/4 or -0.25
to find the x value, any where you see y u put in the y value(-0.25)
So u'll pick just one of the equations above
x + 6(0.25) = 2
x + 1.5 = 2
x = 1.5 + 2
x = 0.5
A snack-size bottle of chocolate milk is better because it cost less.
Answer:
w = 
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
w² + 7² = 14²
w² + 49 = 196 ( subtract 49 from both sides )
w² = 147 ( take the square root of both sides )
w =
Distance to the farm is 24 miles
Step-by-step explanation:
- Step 1: Let the speed of Peggy be x mph. Then the speed of Mike is x + 36 mph. Find the equation of distance for Mike and Peggy to the farm.
Time taken by Mike = 0.5 hr
Time taken by Peggy = 2 hrs
Distance is calculated by the equation Distance = Speed × Time
Distance traveled by Mike = (x + 36) × 0.5
Distance traveled by Peggy = x × 2
- Step 2: Equate the 2 distances of Mike and Peggy as they are the same and find x.
(x + 36) × 0.5 = 2x
0.5x + 18 = 2x
1.5 x = 18
⇒ x = 18/1.5 = 12 mph
- Step 3: Find the distance to the farm.
Distance to the farm = 2x = 24 miles
