Show work ion get it
Step-by-step explanation:
Open the brackets
2t+1-t+9 = -52-8t
Collect the like terms
2t-t+8t = -52-1-9
9t= -62
Divide both sides by 9
t= -62/9

Approximately -6.9
please help! ill give brainlyest! solve the absolute value equation
Answer:
x = [tex]\frac{40}{9}[/tex] , x = - [tex]\frac{56}{9}[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] | [tex]\frac{3}{4}[/tex] x + [tex]\frac{2}{3}[/tex] | - 1 = 1 ( add 1 to both sides )
[tex]\frac{1}{2}[/tex] | [tex]\frac{3}{4}[/tex] x + [tex]\frac{2}{3}[/tex] | = 2 ( divide both sides by [tex]\frac{1}{2}[/tex] )
| [tex]\frac{3}{4}[/tex] x + [tex]\frac{2}{3}[/tex] | = 4
The absolute value always gives a positive result, however, the expression inside can be positive or negative, then
[tex]\frac{3}{4}[/tex] x + [tex]\frac{2}{3}[/tex] = 4 ( multiply through by 12 to clear the fractions )
9x + 8 = 48 ( subtract 8 from both sides )
9x = 40 ( divide both sides by 9 )
x = [tex]\frac{40}{9}[/tex]
-------------------------------------------------------
OR
- ([tex]\frac{3}{4}[/tex] x + [tex]\frac{2}{3}[/tex] ) = 4 , distribute left side
- [tex]\frac{3}{4}[/tex] x - [tex]\frac{2}{3}[/tex] = 4 ( multiply through by 12 to clear the fractions )
- 9x - 8 = 48 ( add 8 to both sides )
- 9x = 56 ( divide both sides by - 9 )
x = [tex]\frac{56}{-9}[/tex] = - [tex]\frac{56}{9}[/tex]

At a hotel 3/4 of 100 rooms are occupied today yesterday 4/5 of 100 rooms were occupied on which day were more rooms occupied in by how much
Answer:
Yesterday 4/5 and by 5 more people
Step-by-step explanation:
Ok so 3/4 of 100 is just 100/4*3, which is 75. 4/5 of 100 is 100/5*4, therefore, equaling 80. So 80 > 75, and when you find by how much more you do 80-75, which is 5. I hope this helps and if you have any questions you can comment them on this answer
Answer:
The answer is 4/5
Step-by-step explanation:
well 3/4 of 100 is 75. 4/5 of 100 is 80.
one fourth is equal to 25. We know that because we divide 100/4 and since there's 3 out of 4 (25x3=75)
one fifth is equal to 20. (100/5 = 20) 4 times 20 equals 80
A cell phone company charges $300 for a new phone and $40 for a monthly plan. If C (t) is a rational function that represents the average monthly cost of owning the cell phone, what is the range of the function?
R: ℝ
R: (0, 300)
R: (40, 340)
R: (–∞, ∞)
Answer:
The $300 charge will last until the new phone is paid off. After that the monthly charge will be $40 only.
The range of the function will be between $40 and $340:
R:[40, 340]Correct choice is C

The width of a rectangle measures (5v-4w)(5v−4w) centimeters, and its length measures (3v+7w)(3v+7w) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
Answer:
P = 2( 8v +3w)
P = 16v +6w
Step-by-step explanation:
P = 2 ( l+w) for a rectangle
P = 2((3v+7w)+ (5v-4w))
Combine like terms
P = 2( 8v +3w)
Distribute
P = 16v +6w

At a school camp there is enough food for 150 students for 5 days.
a How long would the food last if there were only 100
students?
Answer:
6 1/2
Step-by-step explanation:
because we know that for 150 students ther are meals for five days right? now their are only a hundred students and 150 meals, we know that 50+50=100 right? so if we have 100 meals for all of the students that will be enough for 5 days but 50 more meals would mean 6 1/2 days cuss only half of the students will have a meal, their would only be 50 meals for 50 students
please help. i need steps and everything
Answer:
x = 13, y = 24.
Step-by-step explanation:
5x - 8 + 63 + 7x - 31 = 180 (interior alternate angles are equal).
12x + 24 = 180
12x = 180 - 24 = 156
x = 156/12
x = 13.
4y + 27 = 63 + 7x - 31 (interior alternate angles are equal).
4y +27 = 32 +7(13)
4y = -27 +32 + 91
4y = `96
y = 96/4
y = 24.

A teacher has 15 students in his class, 8 girls and 7 boys. He wants to seat them in three rows of five, but knows that if any row has two girls or two boys sitting next to each other, they will talk and won't pay attention. How many seating arrangements can he make that avoid this
Answer:
609638400
Step-by-step explanation:
Answer:
609638400
Step-by-step explanation:
Each row must alternate boys and girls, so every row is either BGBGB or GBGBG, where B denotes a boy and G denotes a girl. Since there are 8 girls and 7 boys, the teacher must have two rows of GBGBG and one row of BGBGB. There are three ways to choose this row, and once this is done, every seat is reserved for either a girl or a boy. There are 8! ways to arrange the girls in their seats, and 7! ways to arrange the boys, so the total number of seating arrangements is 3 * 7! * 8!

15 people fit comfortably in a 6 feet by 6 feet area. Use this value to estimate the size o a crowd that is 30 feet deep on both sides of the street along a 2-mile section of a parade route. (Hint: 1mile= 5,280ft)
158,400 people will fit into an area with a dimension of 30feets by 2 miles.
The area of the street can be calculated thus :
Area = Length × width
Converting the width to feets :
1 mile = 5280 feets
2 miles = x
Cross multiply :
x = 5280 × 2 = 10560 feets
Area = 10560 ft × 30ft = 316800 ft²
Since 15 people fit into an area with dimension which is 6 ft by 6ft
Area = 6 × 6 = 36 ft²
Let x = number of people
15 people = 36 ft²
x people = 316800 ft²
Cross multiply :
x = (316800 × 15) / 36
x = 158,400 people
Hence 158,400 people will fit in.

A shopkeepers bought 500 glass tumblers at rs 40 each . 20 glass tumblers were broken and he sold the rest at rs 45 each. Find his profit or loss percent
if you will solve this questions in copy and send me pictures of the answer then it will be very helpful for me please
500 at 40 each = £20000
To make a profit he needs to make more than £20000
20 broke so he sold 500-20 = 480 at 45 each.
480 x 45 = 21600
Profit = 21600 -20000 = 1600
His profit was £1,600

Answer:
1.06 m²
Step-by-step explanation:
To find the area of the two ends, you need to find the area of the inner circle, then subtract that from the area of the large circle.
As we know, A = πr²
The diameter of the larger circle is 1.8, so the radius is 0.9.
π(0.9)² = 2.54
The diameter of the smaller circle is 1.6, so the radius is 0.8
π(0.8)² = 2.01
2.54 - 2.01 = 0.53 m² (this is for one end)
0.53 x 2 = 1.06 m²
