Walter is helping to make cookies for a basketball tournament. He's made 15 cookies so far. His coach asked him to make at least

Hoochie [10]

Answer:

$5\leq x\leq 40$

Here, $x$ denotes the additional cookies that need to be made by Walter besides 15 cookies made by him so far

Step-by-step explanation:

Number of cookies made by Walter so far = 15

He is asked by his coach to make at least 20 cookies but no more than 55.

Let $x$ denotes the additional cookies that need to be made by Walter besides 15 cookies made by him so far.

The inequality is $20\leq x+15\leq 55$

Now solve this inequality.

$20\leq x+15\leq 55\\20-15\leq x\leq 55-15\\5\leq x\leq 40$

The circle graph shows Tommy Blox spent the money he earned last summer. If he spent $80 on entertainment, how much did Tommy ea

Studentka2010 [4]

Answer:

Tommy earned $250 altogether.

Step-by-step explanation:

Let the total earning of Tommy be 'x' dollars.

Given:

Money spent on entertainment = $80

From the circle shown below:

Percent spent on clothes = 19%

Percent spent on food = 25%

Percent spent on other things = 14%

Percent of savings = 10%

Addition of all percents = 100%

⇒ 19% + 25% + 10% + 14% + % Entertainment = 100%

⇒ 68% + % Entertainment = 100%

⇒ % Entertainment = 100% - 68% = 32%

Therefore, as per question:

$32\%\ of\ x=\$80\\\\0.32x=80\\\\x=\frac{80}{0.32}\\\\x=\$250\\$

Hence, Tommy earned $250 altogether.

How do I solve this?

Vladimir79 [104]

Step-by-step explanation:

Substitute the value x for any number, for example x=1, you substitute x for the value 1, so this is the final equation: y= -3(1)+5 and the answer you get is the value of y. Continue substituting x for any value in the graph of course and then write the answer for y which is the number you get by solving the equation. Then plot the graph with the points you got. Hope this helps, let me know if you need more help :)
