What value of x satisfies the equation x/4 + x/2 =9​

Answers

My work for your question

"12" is the correct value of "x" which satisfies the given equation.

The given equation is:

→  [tex]\frac{x}{4} +\frac{x}{2} =9[/tex]

By taking L.C.M, we get

→  [tex]\frac{x+2x}{4}= 9[/tex]

→  [tex]\frac{3x}{4} =9[/tex]

By applying cross-multiplication, we get

→  [tex]3x=36[/tex]

→    [tex]x = \frac{36}{3}[/tex]

→       [tex]= 12[/tex]

Thus the above is the right answer.

Students at Mendel Middle School are planning a fair for their school's fundraiser. Liam volunteers to help plan the event. The first month, he volunteered for x hours. The next month, he volunteered for 1 2/3 times as many hours as he had the first month. If he volunteered for a total of 40 hours, how many hours did he volunteer during the first month? Write an equation to represent the situation and solve.

Answers

Answer:

15 hours

Step-by-step explanation:

[tex]x[/tex] is the number of hours that Liam volunteered in the first month

The next month he volunteered [tex]1\dfrac{2}{3}[/tex] times the time he volunteered the first month.

Total time he volunteered in the two months is 40 hours so

[tex]x+1\dfrac{2}{3}x=40\\\Rightarrow x+\dfrac{5}{3}x=40\\\Rightarrow \dfrac{3x+5x}{3}=40\\\Rightarrow x=\dfrac{40\times 3}{8}\\\Rightarrow x=15[/tex]

Time he volunteered in the first month is 15 hours.

A local school donated canned goods to help the community. Cans were packed into boxes each weighing 16.4 pounds. The volunteers packed 9 boxes. How many total pounds of food did they collect? A. 97.6 B. 147.6 C. 976 D. 1,476

Answers

Answer:

147.6 pounds of food

Step-by-step explanation:

Each box weighed 16.4pounds, if the volunteers packed 9 boxes, we need to calculate the total pounds of food collected. Using the equality postulate;

1 box = 16.4 pounds

9 boxes = x pounds of food

Cross multiply;

1 * x = 9 * 16.4

x = 147.6 pounds of food

Hence the volunteers collected 147.6 total pounds of food
