Answer:
i believe the answer would be 7
Step-by-step explanation:
3 + 20 ÷ 5 = 7
Answer:
5 x (3 + y) = 20
Step-by-step explanation:
The total amount collected is 20, so it goes on the right side of the = sign. There was a total of 5 students and each student had to pay an attendance fee of $3, so you need to multiply 5 by 3 because each student had to pay the fee. The students also need to pay a fee for supplies, but we do not know what that amount is, so we put a variable in its place. We need to put the total amount of money that each student pays together, so we put it in parentheses. We put the 5 outside of the parentheses, which are on the left side of the = sign. When you solve this equation, you would find that the supply cost would have to be $1 each.

Write the equation of the line that passes through the points (2,-6) and (6,-6).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answ
Step-by-step explanation:
Two point slope =-(-6+6)/(6-2) =0
Equation is y+6 = 0(x-2)
y+6=0
y=-6
The point is -6 at y axis which is a horizontal line.
A pound of chocolate costs 8 dollars. Lamar buys p pounds. Write an equation to represent the total cost ċ that Lamar
pays.
Answer:
8p=c
Step-by-step explanation:
The number of pounds Lamar buys multiplied by the cost of a pound which is 8 equals c. 8p=c
squares q,r,t form a right triangle with dimensions as shown in the diagram. what is the area of square Q
Answer:
The area of square Q is 441 m² ⇒ C
Step-by-step explanation:
Let us use the right triangle to find the side of square Q
∵ The length of the side of square T = 29 m
∴ The length of the hypotenuse of the right triangle = 29 m
∵ The length of the side of square R = 20 m
∴ The length of leg1 of the right triangle = 20 m
∵ (leg1)² + (leg2)² = (hypotenuse)² ⇒ Pyathagoras Theorm
∴ (20)² + (leg2)² = (29)²
∴ 400 + (leg2)² = 841
→ Subtract 400 from both sides
∴ (leg2)² = 441
→ Take √ for both sides
∴ leg2 = 21
∵ Leg2 is the side of the square Q
∴ The length of the side of square Q = 21 m
∵ Area of the square = side × side
∴ Area of square Q = 21 × 21
∴ Area of square Q = 441 m²
∴ The area of square Q is 441 m²

Chris labels every lattice point in the coordinate plane with the square of the distance from the point to the origin (a lattice point is a point such that both of its coordinates are integers). How many times does he label a point with the number $25$?
Answer:
4 times
Step-by-step explanation:
A lattice point may be defined as the point of intersection of two grid lines or more than two grid lines that is placed in a regularly spaced points arrays. This is called a lattice point.
In the context, Chris tries to label every lattice point in a coordinate plane with its square of distance from the point to its origin. The lattice points means that the numbers are both the integers. So for number 25, Chris has to label 4 times
i.e. (55),(-5,5),(5,-5),(-5,-5)
James and Ahmik went to a bicycle show. Of the bicycles they saw at the show, 32% were blue, 25% were red, 25% were green, and 18% were black. In ratio form, what percent of the bicycles were red or black?
Answer: 43:100
Step-by-step explanation:
Percentage of bicycles that are blue = 32%
Percentage of bicycles that are red = 25%
Percentage of bicycles that are green = 25%
Percentage of bicycles that are black = 18%
Percentage of bicycles that are red or black = 25% + 18% = 43%
Therefore, 43% will be written in ratio form as 43:100

Can you please explain how I got it wrong and how to get it right (thank you)
Answer:
x = 42°
Step-by-step explanation:
Since (3x+3) and 129 are corresponding angles, we can set them equal to one another and solve for x.
3x + 3 = 129
- 3 - 3
3x = 126
/3 / 3
x = 42°

Benson purchased a $1,800 certificate of deposit that earns simple annual interest. At the end of 1 year, the certificate was worth $1,857.60.
What is the annual interest rate on this certificate of deposit?
Answer:
3.2%
Step-by-step explanation:
Here, we want to calculate the annual interest rate
The interest is = Amount - principal = 1857.60 - 1800 = 57.60
‘Mathematically;
Interest = PRT/100
P is 1,800
r is rate
t is time = 1
57.60 = (1800 * r * 1)/100
100 * 57.60 = 1800r
r = 5760/1800
r = 3.2%
8) The graphical representation of a linear polynomial is
Curve
Straight line
Parabola
Circle
Answer:
Straight line
Step-by-step explanation:
if for a linear polynomial ax + b, a ≠ 0, the graph of y = ax + b is a straight line which intersects the x-axis at exactly one point, namely, (- b/a, 0). Also, this linear polynomial has only one zero which is the x-coordinate of the point where the graph of y = ax + b intersects the x-axis.
Which of these statements about savings is incorrect? *
1 point
People often believe they are saving when they buy products at a listed
discount, even if they didn't need the product in the first place
It is extremely difficult to open a savings account, as you typically need at
least $10,000 for your initial deposit
Without a vehicle to save (like a savings account), it's much easier to spend
and harder to keep track of finances
Billions of dollars is spent on marketing to persuade consumers to spend
money instead of saving it

Alessia uses her bank card to buy lunch 3 times. Each time she buys lunch, it costs $12.50. She then deposits $30 in her bank account. What is the change in her bank balance in dollars as a result of these transactions?
Answer: She has a $-7.50 balance
Step-by-step explanation: A = 3*12.5
A= 37.5
37.5-30= -7.5
Answer:
Her balance will be $7.50 in the red.
Step-by-step explanation:
expenses: (12.50)*3 = 37.50
funds added: 30
$30 - $37.50 = -$7.50
Which statements are correct interpretations of this graph?
Select each correct answer.
6/10 of a page is edited per minute
3 pages are edited every 5 min
1 2/3 of a page is edited per minute
5 pages are edited every 3 min
Answer:
✅6/10 of a page is edited per minute
✅3 pages are edited every 5 min
Step-by-step explanation:
On the graph, there are 3 points given, which are:
(5, 3), which means 3 pages are edited every 5 mins
(10, 6), which means 6 pages are edited every 10 mins.
(15, 9), which means 9 pages are edited every 9 mins.
Pages edited per minute, using the point (10, 6) would be:
y/x = 6/10. This means ⁶/10 of a page is edited per minute
The correct statements that interprets the graph are:
✅6/10 of a page is edited per minute
✅3 pages are edited every 5 min

Select the function that defines the given sequence.
Answer:
D.
Step-by-step explanation:
a1 = -8
a2 = -8 * 2.5
a3 = -8 * 2.5 * 2.5
a4 = -8 * 2.5^3
an = -8 * 2.5^(n - 1)
The first term is -8. Each subsequent term is 5/2 times the previous term.
