A number plus itself, plus twice itself, plus 4 times itself is equal to -104

NARA [144]

The scenario will will be represented by: $x+x+2x+4x=-104$

The number will be -13

Step-by-step explanation:

We have to convert the given situation into the mathematical form

Let x be the number

Then

"a number plus itself"

x+x

"plus twice itself"

x+x+2x

"plus 4 times itself"

x+x+2x+4x

"is equal to -104"

$x+x+2x+4x=-104$

This can also be written as:

$x+x+2x+4x=-104\\8x=-104\\Dividing\ both\ sides\ by\ 8\\\frac{8x}{8}=\frac{-104}{8}\\x=-13$

ANSWER

$\frac{ {t}^{2} + 4t - 12}{ {t}^{2} - 4 } = \frac{t + 6}{ t + 2}$
where,
$t \ne - 2$

EXPLANATION

We want to simplify the rational expression

$\frac{ {t}^{2} + 4t - 12}{ {t}^{2} - 4 }$

We can observe that the numerator of the given rational expression is a quadratic trinomial and the denominator is a difference of two squares

We need to split the middle term in the numerator and rewrite the denominator as a difference of two squares to obtain,

$\frac{ {t}^{2} + 4t - 12}{ {t}^{2} - 4 } = \frac{{t}^{2} + 6t - 2t - 12}{ {t}^{2} - {2}^{2} }$

We now factor to obtain,

$\frac{ {t}^{2} + 4t - 12}{ {t}^{2} - 4 } = \frac{t (t+ 6) - 2(t + 6)}{ (t - 2)(t + 2)}$

This implies that,

$\frac{ {t}^{2} + 4t - 12}{ {t}^{2} - 4 } = \frac{(t - 2) (t + 6)}{ (t - 2)(t + 2)}$

We now cancel out common factors to obtain,

$\frac{ {t}^{2} + 4t - 12}{ {t}^{2} - 4 } = \frac{(t + 6)}{ (t + 2)}$

The restriction is that, the denominator cannot be zero.

Thus

$t + 2 \ne0$

This implies that,

$t \ne - 2$

Clarissa bought 3 cartons of milk for y cents each she gave the cashier $10. How much change did she receive? Express your answe

e-lub [12.9K]

Answer:

The amount of change she received was $(10-0.03y)$ dollar.

Step-by-step explanation:

Price of each carton of milk is $y$ cents and she bought 3 cartons of milk.

We know that, <u>1 dollar = 100 cents</u>

So, 1 cent = $\frac{1}{100}=0.01$ dollar.

and $y$ cents $=0.01y$ dollar.

Thus, <u>the total price of 3 cartons of milk</u> $=(0.01y*3)=0.03y$ dollar.

She gave the cashier $10.

So, the amount of change she received $=(10-0.03y)$ dollar.

A: ∠3 and ∠2
