-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

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

Step-by-step explanation:
5(1-2x) = -65
5-10x = -65
65+5 = 10x
70 = 10x
7 = x
x = 7
Answer:
X=7/2
Step-by-step explanation:
5(1 - 2x) = -65
5-20x=-65
-20x=-65-5
-20x=-70
Minus sign cancel from both side
So x=70/20
X=7/2

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.
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.

The piece-wise function is defined by:
[tex]f(x) = 1, -3 \leq x < -1[/tex]
[tex]f(x) = 2, -1 \leq x < 1[/tex]
[tex]f(x) = 3, 1 \leq x < 3[/tex]
A piece-wise function is a function that has different definitions, based on the input.
In this graph:
When x is between -3(inclusive, closed circle) and -1(exclusive, open circle), the value is 1, thus, the first definition is:[tex]f(x) = 1, -3 \leq x < -1[/tex]
When x is between -1(inclusive) and 1(exclusive), the value is 2, thus, the second definition is:[tex]f(x) = 2, -1 \leq x < 1[/tex]
When x is between 1(inclusive) and 3(exclusive), the value is 3, thus, the third definition is:[tex]f(x) = 3, 1 \leq x < 3[/tex]
