Answer:
a) How many of the pets were birds and how many were fish?
Number of birds = x = 28
Number of fish = y = 202
b) Equation for pets?
x + y = 230....... Equation 1
c) Equations for cost?
9x + 4y = 1060...... Equation 2
Step-by-step explanation:
The pet store has an abundance of birds and fish and is selling them at a great price there are 230 of these pets In the store the cost for a bird is $9 and the cost per fish is $4 the store sold all the pets in a weekend blow out sale and made $1060 how many of the pets were birds and how many were fish? Equation for pets? Equations for cost?
Let us represent:
Number of birds = x
Number of fish = y
The pet store has an abundance of birds and fish and is selling them at a great price there are 230 of these pets
x + y = 230....... Equation 1
x = 230 - y
In the store the cost for a bird is $9 and the cost per fish is $4 the store sold all the pets in a weekend blow out sale and made $1060
$9 × x + $4 × y = $1060
9x + 4y = 1060...... Equation 2
We substitute 230 - y for x
9(230 - y) + 4y = 1060
2070 - 9y + 4y = 1060
Collect like terms
- 9y + 4y = 1060 -2070
-5y = -1010
y = -1010/-5
y = 202
Solving for x
x = 230 - y
x = 230 - 202
x = 28
Therefore,
Number of birds = x = 28
Number of fish = y = 202

What are the coordinates of point S?
(2, -2)
(-2, 2)
(2, 2)
(2, 0)
Answer:
A: 2, -2
Step-by-step explanation:
the first two represent the x axis and the negative two shows the y axis
Answer:
(2,-2)
Step-by-step explanation:
A set of points is (x,y)
The x-axis is the horizontal line and the y-axis is the vertical line.
Do you see how the point S is in line with 2 on the x-axis? This means that the x point is 2.
Now look across to the y-axis, do you see how point S is in line with -2? This means that the y point is -2.
Put both points together using (x,y)
(2,-2)

Find the perimeter of the semicircle below. Use 3.14 for
pi.
1.6 ft
Answer:
8.2ft
Step-by-step explanation:
Perimeter of a whole circle = 2*pi*r with radius r
Here we have 1.6ft as the radius so the whole circle's perimeter would be
2 * 3.14 * 1.6 = 10.048
We have half the circle so we half this number to 5.024.
Now we have to add the bottom straight line, which is two radii (two lots of 1.6)
5.024 + 1.6 + 1.6 = 8.224 which is rounded to 8.2ft
Serena paid $194.99 for a game system and then bought two equally price games. If she spent a total of $284.97, what is the price, P, of one game? Right and solve an equation
Answer:
44.99
Step-by-step explanation:
284.97(total cost) - 194.99(system cost) = 89.98(money spent on games) / 2(total games) = 44.99 = 44.99 spent per game.

Your teacher is giving a test that has 5 more four-point questions than six-point questions.
The test is worth 120 points. Which system represents this information?
Answer:
x-y=5
4x+6y=120
Step-by-step explanation:
let x = # of 4-point questions
ley y = # of 6-point questions
# of 4-point questions is 5 more than # of 6-point questions
x=y+5 or x-y=5
now there's the matter of the points. Since each x is worth 4 points and each y is worth 6 points, they total number of points have to add up to 120, therefore:
4x+6y=120
The System of Equation is
x-y=5
4x+6y=120
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let x be number of 4-point questions.
ley y be number of 6-point questions.
as, the 4-point questions is 5 more than 6-point questions
So, x=y+5
or x-y=5.................(1)
Since each x is worth 4 points and each y is worth 6 points, they total number of points is 120.
So, 4x+6y=120....................(2)
