What is the largest of the four integers
The integers are 10, 13, 16 and 19 which add up to get a total of 23, 26, 29, 32 and 35
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
The integers are 10, 13, 16 and 19 because:
10 + 13 = 23; 10 + 16 = 26; 10 + 19 = 29
Also;
13 + 16 = 19; 13 + 19 = 32 and 19 + 16 = 35
The integers are 10, 13, 16 and 19 which add up to get a total of 23, 26, 29, 32 and 35

The number of hardcover books will be 3,4, and 8.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Tim is sorting his book collection into groups. He places each group onto bookshelves that can each hold a maximum of 25 pounds. His collection includes hardcover books that weigh 3 pounds each and softcover books that weigh 2 pounds each.
Total weight = 25 pounds
The number of hardcover books which weigh less than 25 pounds is,
3 x 3 pounds = 9 pounds
4 x 3 pounds = 12 pounds
8 x 3 pounds =- 24 pounds
Therefore, the number of hardcover books will be 3,4, and 8.

the shorter piece. What is the length, in feet, of the
longer piece of cable?
F.:.6
G. 13
H. 15
J. 24
K. 26
Answer:
the length of the longer piece of cable is 24 ft
Step-by-step explanation:
shor piece = s
Long piesce = s+9
s + s+9= 39
2s = 30
s = 15
short = 15
15 +9 = 24
long = 24
15+24 = 39
Answer:
24 feets
Step-by-step explanation:
let the shorter cable be x feets
so the longer cable will be 9 plus the shorter cable which is (9 + x) feets
Total length = Longer cable + shorter cable 39 = (9 + x) + x 39 = 9 + 2x2x = 39 - 9 2x = 30[tex]x \: = \: \frac{30}{2} \\ x = 15feets[/tex]

350 people watched a beauty contest. Some paid GH¢20.00 each while others paid GH¢30.00 each. The total amount collected was GH¢8,800.00. Find how many paid the two different rates.
Answer: 170 people paid GH¢20 and 180 people paid GH¢30
Step-by-step explanation:
Let the number of people that paid GH¢20 be represented by x.
Let the number of people that paid GH¢30 be represented by y.
Based on the above information given, we can form an equation which will be:
x + y = 350 ....... i
20x + 30y = 8800 ....... ii
Multiply equation i by 20
20x + 20y = 7000 ...... iii
20x + 30y = 8800 ...... iv
Subtract iii from iv
10y = 1800
y = 1800/10
y = 180
Since x + y = 350
x = 350 - y.
x = 350 - 180
x = 170
Therefore, 170 people paid GH¢20 and 180 people paid GH¢30

Answer:
1,296 cm³Step-by-step explanation:
Now the formula to find the volume of a pyramid is [tex]V=\frac{lwh}{3}[/tex]
We know the length, width and height so let´s get started!
First let´s multiply to find the base. To do so, we will do length × width.
18 × 18 = 324
Now multiply by the height
324 × 12 = 3,888
After you multiply all length, width and height, we need to divide by three.
3,888 ÷ 3 = 1,296
Before we finish, we need to do the last two steps
First we need to add the measurement unit which is centimetres or cm.
We also need to add ³ since it is volume
1,296 cm³ is our final answer

At a concession stand, a pickle and two bags of chips costs a total of $3.25. Three pickles and four bags of chips costs a total of $7.25. To determine the cost of one pickle, Kevin is writing a system of equations. His first equation is shown: x + 2y = 3.25
Which of the following could be the second equation in his system of equations?
3x + 4y = 7.25
4x + 3y = 7.25
3x - 4y = 7.25
(3 + 4)x = 7.25
Answer:
p + 2c = 3.25 Start with these two equations
3p + 4c = 7.25
p = -2c + 3.25 Solve for one variable
3(-2c +3.25) + 4c = 7.25 Substitute
-6c + 9.75 + 4c = 7.25
-2c = -2
c = 1
p + 2(1) = 3.25 Substitute
p + 2 = 3.25
p = 1.25
A bag of chips costs $1
A pickle costs $1.25

Write the equation of the line that is perpendicular to y=2x-7 and passes through the point (6, 5)
A. y=2x-2
B.y= -1/2x+8
C.y=-1/2x-8
D.y=2x=2
Answer:
B
Step-by-step explanation:
we are given a equation of a line
we want to figure out the equation of the perpendicular line passes through the (6,5) points
in order to do so
recall that,
[tex] \displaystyle m_{ \text{perpendicular}} = - \frac{1}{m} [/tex]
we got from our given equation that m=2
because equation of a line is y=mx+b
thus
[tex] \displaystyle m_{ \text{perpendicular}} = - \frac{1}{2} [/tex]
remember that, when we want to figure out perpendicular line or parallel line we should the formula given by
[tex] \displaystyle y - y_{1} = m(x - x_{1})[/tex]
since we got our perpendicular m is -½, [tex]x_1=6[/tex] and [tex]y_1=5[/tex], substitute
[tex] \displaystyle y - 5 = - \frac{1}{2} (x - 6)[/tex]
to get the perpendicular equation you should simplify the above equation to y=mx+b form
distribute -½:
[tex] \displaystyle y - 5 = - \frac{1}{2} x + 3[/tex]
add 5 to both sides:
[tex] \displaystyle y = - \frac{1}{2} x + 8[/tex]
hence,
our answer choice is B

Alyssa is a waitress at a restaurant. Each day she works, Alyssa will make a
guaranteed wage of $20, however the additional amount that Alyssa earns from tips
depends on the number of tables she waits on that day. From past experience, Alyssa
noticed that she will get about $15 in tips for each table she waits on. How much
would Alyssa expect to earn in a day on which she waits on 10 tables? How much
would Alyssa expect to make in a day when waiting on t tables?
Earnings for 10 tables:
Earnings for t tables:
Answer:
$170
20+15t
Step-by-step explanation:
she already makes $20 in a day and then you add the 10 times $15 in tips which makes 170.
for the equation, she makes 20 so you add it to 15 times t which is the hypothetical number of tables
