6x+15=3x+21
3x=6
x=2
Answer:
C
Step-by-step explanation:
She needs 1/4 c and 1/2 c (or 1/2 and 1/4, it's the same both ways because it is addition)
A shows 1/2 and 1/4
B shows 2/8 (which can be reduced to 1/4) and 4/8 (which can be reduced to 1/2)
C shows 1/2 and 4/8 (which can be reduced to 1/2)
D shows 4/8 (which can be reduced to 1/2) and 1/4
so the only choice that does not show the correct about of butter (1/2 and 1/4) is answer C (the one in the bottom left corner)
Let x equal the larger number
Let y equal the smaller number
x+y=63
x=y+11
Sub the second equation into the first equation and solve for y
y+11+y=63
2y+11=63
2y=63-11
2y=52
y=52/2
y=26
Sub y into the second equation
x=y+11
x=26+11
x=37

The equations classified according to the number of solutions are given as follows:
- No solution: -3(3q + 4) = -6q + 12
- One solution: -2(3n - 4) = -6n - 4
- Infinitely many solutions: 8z - 4 = 8z - 4
<h3>How many solutions does the equation 4(2z - 1) = 8z - 4 has?</h3>
We solve the equation, hence:
4(2z - 1) = 8z - 4
8z - 4 = 8z - 4
Equivalent, hence they have infinitely many solutions.
<h3>How many solutions does the equation -2(3n - 4) = -6n - 4 has?</h3>
-2(3n - 4) = -6n - 4
-6n + 8 = -6n - 4
0 = -12, which is false, hence it has no solutions.
<h3>How many solutions does the equation -3(3q + 4) = -6q - 12 has?</h3>
-3(3q + 4) = -6q + 12
-9q - 12 = -6q + 12
3q = -24
q = -8.
One solution.
