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.
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.

Write an inequality that has no solution when
solved-- meaning your answer needs to have a
variable in it.
Answer:
3x > 3x+2
Step-by-step explanation:
inequality with no solutions will give you something that is never true like
3 > 5 so for example you can have
3x > 3x+2
Solve the inequality: 1 < x-2<5
O [3,7]

Answer:
3,7
Step-by-step explanation:
Answer:
(3, 7 )
Step-by-step explanation:
Given
1 < x - 2 < 5 ← add 2 to each interval
3 < x < 7
Since x cannot equal 3 or 7 then use parenthesis for limits, that is
solution is (3, 7)
What value of x satisfies the equation x/4 + x/2 =9
"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.

Eight bottles of soda and four bags of chips cost $16. Six bottles of soda and 7 bags of chips cost $14. How much does a bottle of soda cost? How much does a bag of chips cost?
Answer: soda 1.75 dollars and chips is 0.50 dollars
Step-by-step explanation:you have to work out the question like a simultaneous equation so key s=soda and c=chips
8s+4c=16
6s+7c=14 make chips equal
56s+28c=112
24s+28c=56 Take the equations away
32s=56
S=56\32
S=7/4
S=1.75 sub that answer in the first equation
8*1.75=14
14+4c=16
4c=2
C=0.5

Last month you spend $30 on clothing this month you spent 160% of what you spent last minute set up a proportion to model this situation how much did you spend this month
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that last month $30 was spent on clothing and that this month, 160% of what was spent last month.
The equation to to model this situation will be:
= 160% × $30
= 160/100 × $30
= 1.6 × $30
= $48
That means $48 will be spent this month.

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
Answer:
147.6 pounds of foodStep-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
-7(x + 9) = 9(x - 5) - 14x Solve for x. SHOW WORK.
Answer:
x=-9
Step-by-step explanation:
STEP 1: Since x is on the right side of the equation, switch the sides so it is on the left side of the equation.
[tex]9(x-5)-14x=-7(x+9)[/tex]
STEP 2: Simplify 9(x−5)−14x.
[tex]-5x-45=-7(x+9)[/tex]
STEP 3: Simplify −7(x+9).
[tex]-5x-45=-7x-63[/tex]
STEP 4: Move all terms containing x to the left side of the equation.
[tex]2x-45=-63[/tex]
STEP 5: Move all terms not containing x to the right side of the equation.
[tex]2x=-18[/tex]
STEP 6: Divide each term by 2 and simplify.
[tex]x=-9[/tex]
Answer:
x= -9
