Solve for x: −34x−1=115 .
krek1111 [17]

Answer:

x = -\frac{64}{45}

Step-by-step explanation:

-\frac{3}{4}x - 1 = \frac{1}{15}

add 1 to both sides:

-\frac{3}{4}x = \frac{16}{15}

multiply both sides by 4:

-3x = \frac{64}{15}

divide both sides by -3:

x = -\frac{64}{45}

A store is selling two mixtures of coffee beans in one-pound bags. The first mixture has 12 ounces of Sumatra combined with 4 ou
ololo11 [35]
We let x as the cost of one ounce of Sumatra and y as the cost of one ounce of Celebes Kalossi. For mixture 1, we have 12x + 4y = 32 and for mixture b, we have 4x + 12y = 40

First, Multiply eq. 1 by 4
4(12x + 4y = 32)4        ⇒    36x + 12y = 96

We now have 
(36x + 12y = 96) – (4x + 12y = 40)
<span>X = 1.75     ⇒ cost of one ounce of Sumatra 
</span>
Substitute x to either equation to get the value of y
12(1.75) + 4y = 324
y = 32-21
4y = 11
Y = 2.75     ⇒ cost of one ounce of Celebes Kalossi
