bisector. Base. In geometry, the base of a shape is the side (usually the bottom) that forms a right (90 degree) angle with the height of the object. Biannual.
We can solve this system of equations using substitution.
2y + 2x = 8
Solve for x.
2x = -2y + 8
Divide all terms by 2.
x = -y + 4
Take the equation x = -y + 4 and substitute it into the second system of equation.
2y - 4x = 2
2y - 4(-y + 4) = 2
Simplify by distributing.
2y + 4y - 16 = 2
Combine like terms.
6y - 16 = 2
6y = 18
y = 3
Now that you know the numerical value of y, substitute y with 3 in both equations to find x.
1) 2y + 2x = 8
2(3) + 2x = 8
6 + 2x = 8
2x = 2
x = 1
2) 2y - 4x = 2
2(3) - 4x = 2
6 - 4x = 2
-4x = -4
x = 1
The value of x is 1, and the value of y is 3.
Solution: B) (1, 3)
5 + (-10) = 5 - 10
= -5 .
5 + (-3) = 5 -3
=2 .
5 + 3 = 8 .
5 + 0 = 5 .
Answer:
Step-by-step explanation:
Part 1
$6.84 + $4.88 + $8.32 + $4.98 = $25.02
The total cost of the steaks comes to $25.02.
Part 2
2 × 20 = 40
40 - 25.02 = 14.98
1.25 is 5% of 25.02
14.98 - 1.25 = 13.73
The family gets $13.73 back in change.
Part 3
6.84 ÷ 12 = 0.57
4.88 ÷ 8 = 0.61
8.32 ÷ 16 = 0.52
4.98 ÷ 6 = 0.83
Part 4
0.83 - 0.52 = 0.31
They should buy larger steaks to share because the larger steaks are $0.31 cheaper than the smaller steaks.
