Georgia [21]3 years ago
5 0

Answer:

0

Step-by-step explanation:

33x + 99 = 33x - 99

→ Minus 99 from both sides

33x = 33x - 198

→ Minus 33x from both sides

0x = 198

Answer:

No real solutions

Step-by-step explanation:

If you rearrange the equation:

33x - 33x = -99 - 99

0x = -198

Anything divided by zero is undefined/no real solution

Answer:

Carmen can make 10\frac{5}{16} full servings.

Step-by-step explanation:

Given : Carmen mixes 3\frac{1}{2} cups of water with 3\frac{3}{8}  cups of juice to make punch.

Total quantity of punch Carmen made = total cup of water + cup of juice she mixes

Total quantity of punch Carmen made = 3\frac{1}{2}+3\frac{3}{8}

Solving , we get,

Total quantity of punch Carmen made = \frac{7}{2}+\frac{27}{8}

taking LCM(2,8) = 8 , we get,

Total quantity of punch Carmen made = \frac{28+27}{8}=\frac{55}{8}

Also, given She pours \frac{2}{3} cup servings of punch.

Thus, \frac{2}{3} cup of mixture makes 1 serving cup.

Using unitary method,

In unitary method we first find the value of a single quantity and then multiply it with the desired quantity.

1 cup of mixture makes \frac{3}{2} serving cup.

\frac{55}{8} cup makes = \frac{3}{2}\times\frac{55}{8}

\frac{55}{8} cup makes = \frac{165}{16}=10\frac{5}{16}

Thus, She can make 10\frac{5}{16} full servings.

How many 1/10s in 2 3/5
Umnica [9.8K]

It'd be clearer if you'd write:  "How many tenths are there in 2 3/5?"

2 3/5        13/5

---------- = ---------- = 26

(1`/10)        1/10

There are 26 tenths in 2 3/5.

Please help me with these questions about x and y coordinates.
tatyana61 [14]

Answer:

-10

Step-by-step explanation:

You are asked to tell the y-value of the solution. You can find the whole solution and then report the y-value, or you can just find the y part of the solution. We choose the latter.

This is basically done by eliminating the x-variable. It can be done using the "elimination" method of solving these equations. And it can also be done using the "substitution" method of solving these equations. We choose the latter.

Add 14 to the second equation to solve for x:

... x = y + 14

Substitute this into the first equation.

... 3(y +14) -y = 22

... 2y +42 = 22 . . . . . . simplify

... y +21 = 11 . . . . . . . . divide by 2

... y = -10 . . . . . . . . . .  subtract 21

_____

<em>Comment on additional solution methods</em>

A graphing calculator can show you the solution, as in the attachment. Of the solution (x, y) = (4, -10), we are only interested in y = -10.

Cramer's rule can find just one variable value, too. For that, it is convenient to write the system as ...

  • 3x -y = 22
  • x - y = 14 . . . . . add 14-y to the equation given

Then the solution for y is ...

... y = (22·1 -14·3)/(-1·1 -(-1)·3) = -20/2 = -10
