Answer:
x = 1.75
Step-by-step explanation:
Given
3.5(2.25 + x) = 14 ( divide both sides by 3.5 )
2.25 + x = 4 ( subtract 2.25 from both sides )
x = 1.75

Step-by-step explanation:
A group of 8 friends went to lunch and spent a total of $76, which included the food bill and a tip of $16. They decided to split the bill and tip evenly among themselves.
Which equations and solutions describe the situation? Select two options.
The equation StartFraction 1 over 8 EndFraction (x + 16) = StartFraction 76 over 8 EndFraction represents the situation, where x is the food bill.
The equation StartFraction 1 over 8 EndFraction (x + 16) = 76 represents the situation, where x is the food bill.
The solution x = 60 represents the total food bill.
The solution x = 60 represents each friend’s share of the food bill and tip.
The equation 8 (x + 16) = 76 represents the situation, where x is the food bill.
Answer:
1) The equation 1/8(x+16)=76/8 represents the situation, where x is the food bill.
2) The solution x=60 represents the total food bill.
These both answers are correct.
Step-by-step explanation:
Since there are 8 group of friends, and the total amount spent by them is $76 including the tip i.e $16.
If x is the food bill our equation can be:
(x+16)/8 = 76/8
(x+16)/8 = 9.5
x+16= 9.5*8
x= 76 -16
x= 60
The food bill is x=60.

On a certain hot summers day, 672 people used the public swimming pool. The daily prices are $1.50 for children and 2.50 for adults. The receipts for admission totaled $1289.00. How many children and how many adults swam at the public pool that day?
Water is pumped out of a 500-gallon tank at a rate of 2.5 gallons per second. The inequality 500−2.5t<100 can be used to determine the time t in seconds, after which there will be less than 100 gallons of water remaining in the tank.
Answer:
[tex]160\ \text{s}[/tex]
Step-by-step explanation:
The inequality that represents the situation is
[tex]500-2.5t<100[/tex] where [tex]t[/tex] is the time in seconds
[tex]\Rightarrow -2.5t<100-500[/tex]
[tex]\Rightarrow -2.5t<-400[/tex]
[tex]\Rightarrow 2.5t>400[/tex]
[tex]\Rightarrow t>\dfrac{400}{2.5}[/tex]
[tex]\Rightarrow t>160\ \text{s}[/tex]
So, the time after which there will be less than 100 gallons of water is [tex]160\ \text{s}[/tex].

what conclusions can you give why some students decided not to go to school?
Step-by-step explanation:
There are a number of reasons why some students decide not to go to school. Some of them may be associated with family and psychological problems such as anxiety and depression, which should be investigated by trained professionals at the school if there is any suspicion of these symptoms.
There is also the possibility that students who have decided not to go to school have been victims of bullying and aggression at school, which causes fear of retaliation and psychological trauma that negatively impact the person's life.
It is important that schools provide psychological support and an active policy that combats bullying and is pro-integration of students and diversity.

In PQR, Q= 76, PQ = 18, and QR = 27
Please find angle P, T and PR for 5
Answer:
Step-by-step explanation:
Given:
m<Q = 76°
PQ = r = 18
QR = p = 27
Required:
Find P, T, and PR (q)
Solution:
✔️To find PR(q), apply the Law of Cosines.
Thus:
q² = r² + p² - 2rp×cos(Q)
Plug in the values
q² = 18² + 27² - 2×18×27×cos(76)
q² = 1,053 - 235.148
q² = 817.852
q = √817.852
q = 28.6 (nearest tenth)
✔️Find P by applying the Law of Sines:
[tex] \frac{sin(P)}{p} = \frac{sin(Q)}{q} [/tex]
Plug in the values
[tex] \frac{sin(P)}{27} = \frac{sin(76)}{28.6} [/tex]
[tex] sin(P) = \frac{sin(76)*27}{28.6} [/tex]
[tex] sin(P) = 0.9160 [/tex]
[tex] P = sin^{-1}(0.9160) [/tex]
P = 66.3° (nearest tenth)
✔️R = 180 - (P + Q)
R = 180 - (66.3 + 76)
R = 37.7°

Part I. A New Bike and Skateboard Problem
Uncle Eddie asked McKenna and Lara to order 108 new wheels for the 42
skateboards and bicycles in his repair shop. How many bicycles and how
many skateboards are in Uncle Eddie's shop?
Answer:
Number of bicycles = 30
Number of skateboards = 12
Step-by-step explanation:
Let the number of bicycles = x
Let number of skateboards = y
It is given that there are total bicycles and skateboards = 42
∴ x + y = 42 ........(1)
Now a bicycle has two tires and a skateboard has four tires, this gives an equation :
2x + 4y = 108 .......(2) (Since uncle Eddie asks to order 108 tires)
Therefore, solving equation (1) and (2), we get
2(x+y=42)
2x+4y=108
2x+2y = 84
- (2x+4y = 108)
- 4 y = - 24
or 4 y = 24
or y = 12
Now substituting the value of y in equation (1),
x + 12 = 42
x = 42 -12
x = 30
So number of bicycles = x =30
And number of skateboards = y = 12

Your total at a
restaurant is $50. If you
want to tip the server
15%, what is your
total?
Answer:
tip: $7.50
total: $57.50
Step-by-step explanation:
you change the 15% into a decimal by moving the the decimal point 2 spots to the left so now you have .15
next do .15 * 50 to get 7.5, which is the tip
now to find the total, add 7.5 + 50 to get 57.5
Answer:
your total cost would be $57:50

Only 3% of turtle hatchlings will live to become breeding adults. How many turtles must have been born if the current number of breeding adults is 1,200?
Answer:
116400 I believe not 100% sure tho
The total number of turtles born is 40,000.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, only 3% of turtle hatchlings will live to become breeding adults.
The current number of breeding adults is 1,200
Let the total number of turtles born be t.
Now, 3% of t=1200
3/100 ×t=1200
3t=120000
t=40000
Therefore, the total number of turtles born is 40,000.

Find the measure of the indicated angle to the nearest degree?
Please hurry
Answer:
45 degrees
Step-by-step explanation:
Using the pythagorean theorem, the 3rd side=19. So the triangle is isosceles and therefore the 2 angles we don't know the measure of are congruent. One angle measures 90 degrees. So the last 2 angles must be 90 together, since we know a triangle equals 180 degrees. Therefore the angle we are trying to find is 45 degrees.
