Mr. Chin asked his class to solve for y in the equation 8(3y - 5) = 9(y - 5) -1. Explain how to solve for y. Then solve.
Answers
Answer:
[tex]\Huge \boxed{\boxed{\bf{y = -\frac{2}{5} }}}[/tex]
Step-by-step explanation:
To solve for [tex]\tt{y}[/tex] in the equation [tex]\tt{8(3y - 5) = 9(y - 5) - 1}[/tex], we'll need to simplify and isolate the variable.
Let's start by distributing the 8 on the left side and the 9 on the right side of the equation:
[tex]\tt{8(3y - 5) = 9(y - 5) - 1}[/tex][tex]\tt{24y - 40 = 9y - 45 - 1}[/tex]Next, we'll combine like terms on both sides of the equation:
[tex]\tt{24y - 40 = 9y - 46}[/tex]To isolate the variable, we'll move all the terms involving y to one side of the equation. Let's subtract 9y from both sides:
[tex]\tt{24y - 9y - 40 = 9y - 9y - 46}[/tex]Simplifying further, we have:
[tex]\tt{15y - 40 = -46}[/tex]To isolate "y," let's add 40 to both sides:
[tex]\tt{15y - 40 + 40 = -46 + 40}[/tex]Simplifying, we get:
[tex]\tt{15y = -6}[/tex]Finally, we can solve for "y" by dividing both sides of the equation by 15:
[tex]\tt{\frac{15y}{15} = \frac{-6}{15}}[/tex]Simplifying the equation, we have:
[tex]\tt{y = -\frac{2}{5} }[/tex]So, the solution to the equation is y = -2/5.

What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
A chef made 150 cups of chili and sold 60% of it. Then the number of cups of chili that he sold will be calculated as,
⇒ 60% of 150
⇒ 0.60 x 150
⇒ 90 cups
The serving size of the chili is 1 ²/₃ cups.
Convert the mixed fraction number into a fraction number, then we have
1 ²/₃ cups = 1 + 2/3
1 ²/₃ cups = 5/3 cups
Then the number of servings of the chili sold will be calculated as,
⇒ 90 / (5/3)
⇒ 90 x (3 / 5)
⇒ 18 x 3
⇒ 54
The number of cups of chili that he sold will be will be 90 cups. Then the number of servings of the chili sold will be 54.

12,455 + x = 23,894
x = 10,560
Step-by-step explanation:
Let's say that the variable 'x' represents the salaries for the second month, so out equation would be:
10,205 + x = 23,894
To solve, we must isolate the variable by subtracting 12,455 from both sides:
10,205 + x = 23,894
-10,205 -10,205
x = 10,560
So, the second month's salary was $10,560
Step-by-step explanation:
Answer: x = $30,560
Step-by-step explanation:
1. Let the second month payment be x
2. The first month + The second month = both of the months
3. So substituting: 10,205 + x = 40,765
4. Subtract 10,205 from both sides: x = 30,560

Which expression can be used to find the surface area of the triangular prism? Will give Brainliest!
Answers
Answer:
C
Step-by-step explanation:
It is usually A= 1/2 B*H which 1/2*3*4 in parentheses would fit this, but im not 100% sure!
• We have two congruent right triangles with bases=3 and heights=4
• 3 Rectangles, which all share the same width: width=2
Since we are dealing with two-dimensional figures, we must use the area formulas for them.
Area of triangle:
A=1/2•B•H
Area of a rectangle:
A=L•W
Because we have two congruent triangles, their areas must be congruent, too. So, we have double the area of one triangle. So, we can modify the formula:
A=2(1/2•B•H)
Because all three rectangles share the same width but have different lengths, we can add their lengths together to form one whole rectangle.
4+3+5=12
So, all three rectangles’ sides have been combined (added) to form one whole rectangle with the dimensions:
12 by 2.
Now, because the surface area is the total area used to form the faces of a 3-D shape, we must add all the areas of the figures together.
Area of a triangle (modified)
A=2(1/2•3•4)
Area of rectangle:
A=12•2
Simplify:
Triangle:
A=2(6)
A=12
Rectangle:
A=12•2
A=24
Now, let’s add the areas together:
12+24=36
So, the surface area is 36ft^2.
Now, to answer the question, option 3.) is correct

Answers
The number of hours that Sam’s Soups is open on Sunday will be 14 hours.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Sam's Soups is open 6 days per week, 76 hours altogether. Its hours are similar consistently, besides on Saturday and Sunday. On those days, it is open 2 hours longer.
Let 'x' be the number of hours spent on Saturday and Sunday. Then the equation is given as,
x + x + (x - 2) + (x - 2) + (x - 2) + (x - 2) = 76
Simplify the equation, then we have
6x - 8 = 76
6x = 84
x = 14 horus
The number of hours that Sam’s Soups is open on Sunday will be 14 hours.

Sam’s Soups is open 6 days a week, 76 hours in all. Its hours are the same every day, except on Saturday and Sunday. On those days, it is open 2 hours longer. How long is Sam’s Soups open on Sunday? Use an equation to solve.
Answers
Answer:
14 hours
Step-by-step explanation:
Let x be the number of hours open on each of the four days (because it is six days per week) that are not Saturday or Sunday. Thus, the total number of hours on those days would be 4x. Then, we are told that Sam's Soups are open 2 hours longer on Saturdays and Sundays, so that would be x + 2. There are two of those days, so that would be 2(x + 2). Since all of these hours total 76, we have our equation:
4x + 2(x + 2) = 76
4x + 2x + 4 = 76
6x = 72
x = 12
Remember, 12 hours is the number of hours that Sam's Soups is open on days that are not Saturday and Sunday. Those days are x + 2. Thus, that is 12 + 2 = 14 hours.
Answer:
14 hours
Step-by-step explanation:
x = hours on day other than saturday and sunday
y = hours on Saturday and Sunday.
Sam's soups are only open 6 days a week, and 2 are weekends, so it is only open on 4 weekdays.
4x + 2y = 76
We know the hours on Saturday and Sunday are 2 hours more than the weekday hours.
So,
y = x + 2
Substituting that back into the original equation,
4x + 2(x+2) = 76
4x + 2x + 4 = 76
6x = 72
x = 12
y = 14
So Sam's Soups is open 14 hours on Sunday.
