Answer:
[tex]5\dfrac{7}{8} c +7[/tex]
Step-by-step explanation:
The like terms are the ones containing the variable 'c'. They are combined by adding their coefficients.
Working just with the coefficients of c, we have ...
[tex]2\dfrac{3}{4} +3\dfrac{1}{8}=(2+3)+\left(\dfrac{6}{8}+\dfrac{1}{8}\right)=5\dfrac{7}{8}[/tex]
Then the simplified expression is ...
(2 3/4)c +(3 1/8)c +7
= (5 7/8)c +7

Step-by-step explanation:
A band sells tickets to a concert cost either $15 for adults or $10 for students. A total of 150 tickets are sold. If the band made $2000, how many of each ticket are sold? Write and solve a system to find how many adult tickets were sold.
Answers
Answer:
Number of adult tickets sold= 100
Step-by-step explanation:
Giving the following information:
Adults tickets= $15
Student tickets= $10
Number of tickets sold= 150
Total sales= $2,000
First, we determine the systems of equations:
15*x + 10*y= 2,000
x + y = 150
x= number of adults tickets sold
y= number of students tickets sold
Now, we isolate x in one equation, and substitute it in the other one:
x= 150 - y
15*(150 - y) + 10y = 2,000
2,250 - 15y + 10y = 2,000
250 = 5y
50= y
x= 150 - 50
x= 100
Prove:
15*100 + 10*50= 2,000
100 + 50 = 150
Find the value of x.

What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have the following statement Angelo cashed a check for $170, the bank teller gave him 12 bills, some $20 bills and the rest $10 bills
We can write -
20x + 10y = 170
x + y = 12
So, we can write -
y = 12 - x
We can write -
20x + 10(12 - x) = 170
20x + 120 - 10x = 170
10x = 50
x = 5
then -
y = 7
Therefore, he recieved 5 bills of $20 and 7 bills of $10.

Approximately 15% of Americans have a blood type of B. The local blood bank has 80 donors stop by on a given day (which can be considered a random sample from the population). What is the probability that between 15% and 20% of the donors on a given day have a blood type of B?
Answers
Answer: the probability that between 15% and 20% of the donors on a given day have a blood type of B is 0.3944
Step-by-step explanation:
Given that;
Binomial Distribution
n = 80
p = 0.15
q = 1 - p = 0.85
Mean = μ = np = 80 X 0.15 = 12
SD = σ = √(npq) = √(80 x 0.15 x 0.85) = -3.1937
Now; Assumptions in normal distribution to binomial distribution
- The sample size = n = 80 > 30 . Large sample
- np = 80 × 0.15 = 12 > 10
- nq = 80 × 0.85 = 68 > 10
so
80 × 0.15 = 12
80 × 0.20 = 16
To find P(12 < X < 16):
Z = (16 - 12) / 3.1937
= 4 / 3.1937
= 1.2525
Table of Area Under Standard Normal Curve gives area = 0.3944
Therefore the probability that between 15% and 20% of the donors on a given day have a blood type of B is 0.3944

Which inequality represents the situation below, where p is the price of the skateboard before tax:
“Celia has at least $150 to spend on a skateboard, including 6% sales tax”
Answers
Answer:
13
Step-by-step explanation:
2+1=21-13=13
Inequalities are used to represent unequal expressions.
The inequality that represents the situation is [tex]p \ge 150[/tex]
The amount Celia has is at least $150.
The term "at least" in inequalities means "greater than or equal to"
So, the inequality would be:
[tex]p \ge 150[/tex]
Hence, the inequality that represents the situation is [tex]p \ge 150[/tex]

Cole and Bryton went to video Game Land. Cole won 152 tickets. Bryton won 84 tickets. They want to put their tickets together to get a large toy monkey that costs 300 tickets. How many more tickets do they need?
Answers
Answer:
64 tickets
Step-by-step explanation:
First, let's find how many total tickets Cole and Bryton have so far.
Cole has 152 tickets, while Bryton has 84, so adding these yields:
152 + 84 = 236 tickets
In total, they need 300 tickets, so to find how many more they need, we must subtract 236 from 300:
300 - 236 = 64 tickets
Answer:
64 tickets
