<span>x+y = 23 and 2x+3y=55; The wording of the answer choices were confusing, but both of these come together to make the correct answer. First, you need x (number of bracelets) + y (number of necklaces) to determine how many of each were sold. Then, you add 2x (cost of each bracelet x bracelets sold) and 3y (same as bracelets but for necklaces). This results in the total amount sold.</span>

Value of x for 12(x-2)+3x=1/2(x+6)+2

Damm [24]

Answer:

The value of x = 2

Step-by-step explanation:

Given the equation

$12\left(x-2\right)+3x=\frac{1}{2}\left(x+6\right)+2$

Expand 12(x-2) = 12x - 24

Expand 1/2(x+6) = 1/2x + 3

so the equation becomes

$12x-24+3x=\frac{1}{2}x+3+2$

simplifying

$15x-24=\frac{1}{2}x+5$

$15x=\frac{1}{2}x+29$

multiplying both sides by 2

$30x = x + 58$

subtracting x from both sides

$30x - x = 58 - x$

$29x = 58$

divide both sides by 29

$\frac{29x}{29}=\frac{58}{29}$

simplifying

$x = 2$

Therefore, the value of x = 2

Round 0.978 to the nearest tenth

Setler79 [48]

The answer is one, because the number seven in the hundredths column is greater than five so you round the nine up to 1.0.

The vertex of this parabola is at (-3, 6). Which of the following could be its equation?

12345 [234]

Nice, already in vertex form
y=a(x-h)^2+k
(h,k) is vertex

therfor since (-3,6) is vertex
we are looking for something like
y=a(x-(-3))^2+6 simplified to
y=a(x+3)^2+6

A is ansre
