How do you solve, y - 5 =-8 ?

To solve, you would first take the equation y-5=-8, and add 5 on each sides. (To solve an equation, you need to isolate the variables. Adding 5 on both sides will cancel out the "- 5". in order to do this you must do it to both sides so it will still be even.) You should now have Y = -3. to check this, you can say "-3 - 5 =", and your answer will be -8.

Answer:

$y=2,\:x=\frac{5}{2}$

Step-by-step explanation:

$\begin{bmatrix}x+1\cdot \:x+y=7\\ y=2\end{bmatrix}$

x+1· x+2=7

Simplify x+1· x+2: 2x+2x+1· x+2

Add similar elements: x+1· x=2x=2x+2

2x+2=7[ 2x+2=7 ]

Isolate x for 2x+2=7: x=52 2x+2=7

Subtract 2 from both sides

2x+2−2=7−2

Simplify

2x=5

Divide both sides by 2

2x2 =52 Simplify

Chef Selena is making her special dish that requires pasta, sauce, and onions. She has 5 1/8 pounds of pasta, 6 pounds of sauce,

arlik [135]

Answer:

$\text{Total Weight of Food Made}, x=5\frac{1}{8}+6+4\frac{7}{8}\\\text{Number of Servings}, y=x \div \frac{1}{2}$

Step-by-step explanation:

The Weight of Ingredients to be used by Chef Selena are:

$5\frac{1}{8}$ pounds of pasta,
6 pounds of sauce; and
$4\frac{7}{8}$ pounds of onions.

Total Weight of Food Made, x

$=5\frac{1}{8}+6+4\frac{7}{8}\\=5+6+4+\frac{1}{8}+\frac{7}{8}\\=16 \: Pounds$

Since each serving is $\frac{1}{2} Pounds$

Number of Servings of her dish, y

$16 \div \frac{1}{2}\\ =32 \: Servings$

The two equations needed to solve the problem are therefore:

$\text{Total Weight of Food Made}, x=5\frac{1}{8}+6+4\frac{7}{8}\\\text{Number of Servings}, y=x \div \frac{1}{2}$
