A number, y, is equal to twice the sum of a smaller number and 3. The larger number is also equal to 5 more than 3 times the sma

Anit [1.1K]

The first equation gives:

y = 2 * (x + 3) >>> y = 2x + 6

2x - y = -6

The second sentence gives:

y = 5 + 3x >>> 3x - y = -5

The answer is (A), the first choice.

What is the quotient of -8x∧6 over 4x∧-3 ??

Allushta [10]

Answer:

$-2x^{9}$ is the quotient

Step-by-step explanation:

We have two expression $-8x^6$ and $4x^{-3}$

We need to find quotient of this expression using exponent law.

First we write as quotient form,

$\Rightarrow -\dfrac{8x^6}{4x^{-3}}$

$\Rightarrow -2x^{6-(-3)}$ $(x^m\div x^n=x^{m-n})$

$\Rightarrow -2x^{6+3}$

$\Rightarrow -2x^{9}$

Thus, $-2x^{9}$ is the quotient of $-8x^6$ and $4x^{-3}$ .

Bernie spends $6.50 on ingredients and cups for his lemonade stand. He charges $1.50 for each cup of lemonade. How many cups, x,

siniylev [52]

Answer:

18 cups.

Step-by-step explanation:

We are given that Bernie spends $6.50 on ingredients and cups for his lemonade stand. He charges $1.50 for each cup of lemonade. Inequality that represents this situation: $20\leq 1.50x-6.50$ .

To find number of cups x to make a profit of at least $20 we will use our given inequality.

$20\leq 1.50x-6.50$

$20+6.50\leq 1.50x$

$26.50\leq 1.50x$

$x\geq \frac{26.50}{1.50}$

$x\geq \frac{53}{3}$

$x\geq 17.6666666$

Therefore, in order to make a profit of at least $20 Bernie need to sell 18 cups of lemonade.
