Answer:
x=4
Step-by-step explanation:
2/3 x + 5/6 = x - 1/2
Multiply each side by 6 to clear the fractions
6(2/3 x + 5/6) = 6(x - 1/2)
Distribute
4x +5 = 6x-3
Subtract 4x from each side
4x+5 -4x = 6x-3-4x
5 = 2x-3
Add 3 to each side
5+3= 2x-3+3
8 =2x
Divide by 2
8/2 =2x/2
4 =x
Answer:
9
Step-by-step explanation:
one angle here is 60 degrees.
7x-3=60
7x=63
x=9

1 serving = 2/3 cup
12 serving = 2/3 x 12 = 8 cups
Answer: 12 servings of muffin would need <u>8 cups</u> of the muffin mix.
(8,5)(-12,-9)
slope = (-9 - 5) / (-12 - 8) = -14/-20 = 7/10
y = mx + b
slope(m) = 7/10
use either of ur points.....(8,5)....x = 8 and y = 5
now we sub and find b, the y int
5 = 7/10(8) + b
5 = 56/10 + b
5 - 56/10 = b
50/10 - 56/10 = b
-3/5 = b
so ur equation is : y = 7/10x - 3/5.....now we put it in standard form
y = 7/10x - 3/5...multiply by 10
10y = 7x - 6.....subtract 7x
-7x + 10y = -6....multiply by -1
7x - 10y = 6
So.....7x - 10y = 3.... IS NOT a good model. Because ur points are not a solution to ur equation.
