Answer:
5) 2 7) 4
Step-by-step explanation:
3/5 x 25 = 15
15 - 1 = 14 / 7 = 2 = x
25 20
--- = ----
40 7x+4
25 x 4/5 = 20
40 x 4/5 = 32
32 - 4 = 28 / 7 = 4 = x
Renee has a total of 12 cookies in chocolate chip and peanut butter, C + P = 12. The number of chocolate chip cookies is three times the number of peanut butter cookies, C = 3P. How many of each type of cookie does she have?
Answer:
Renee has 9 Chocolate chip cookies and 3 peanut butter cookies.
Step-by-step explanation:
This is a system of equations:
C + p = 12
C = 3P
All you need to do is substitute C for 3P in the first equation.
C + P = 12
3P + P = 12
4P = 12
Divide both sides by 4
4P/4 = 12/4
P = 12/4
P = 3
Now, substitute P for 3 in the first equation.
C + P = 12
C + 3 = 12
Subtract 3 from both sides
C + 3 - 3 = 12 - 3
C = 12 - 3
C = 9
C = 9, P = 3
Set up a system of equations in 2 variables.
Solve the system of linear equations by graphing
y=1/3x+5
y=2/3x+5
What is the solution
Answer:
We have the system of equations:
y=1/3x+5
y=2/3x+5
To solve it graphically, we need to graph both lines and see in which point the lines intersect.
You can see the graph below, and you can see that the lines intersect in the point (0, 5)
Now, we can also solve this analytically.
We can use the fact that for the solution, we need y = y.
Then we can write:
(1/3)*x + 5 = (2/3)*x + 5
First, we can subtract 5 in both equations to get:
(1/3)*x = (2/3)*x
This only has a solution when x = 0.
Replacing x = 0 in one of the equations, we get:
y = (1/3)*0 + 5 = 5
Then the solution is x = 0, and y = 5, as we already could see in the graph.
Triangle ABC has coordinates A(-2, -3), B(1, 1), and C(2, -1). If the triangle is translated 4 units up, what are the coordinates of A'?
Answer:
The coordinates of point A' will be: A'(-2, 0)
Step-by-step explanation:
We know that a translation is basically a transformation that occurs when an object is moved from one place to another place.
Translation does not change the size, orientation, or shape of the original object.
Translating a point P(x, y) 4 units up means we need to add to use P'(x, y+4), that is adding 4 units to the y-coordinate of the point P'(x, y).
Now we have to translate the triangle 4 units up. So, use the formula
P(x, y) → P'(x, y + 3)
Thus, the coordinates of point A' will be:
A(-2, -3) → A'(-2, -3+3) → A'(-2, 0)
Therefore, the coordinates of point A' will be: A'(-2, 0)

The height of 2 ball in meters is given by the quadratic equation y= -5+² +14t +3, where t is the time in seconds. After how many
seconds will the ball hit the ground?
Answer: after 3 seconds
when the ball hit the ground => - 5t² + 14t + 3 = 0
⇔ (5t + 1)(t - 3) = 0
⇔ t = 3 or t = -1/5
but t is a positive integer => t = 3
so the ball will hit the ground after 3 seconds

The volume of vegetable soup in a serving is proportional
to the mass of the serving. A 290 mL serving of vegetable
soup has a mass of 180 g. What is the mass of a 348 mL
serving of soup?
Answer:150
Step-by-step explanation:
The mass of 348mL serving soup is 216 grams
The serving is proportional; so, we have:
[tex]\mathbf{290mL = 180g}[/tex]
[tex]\mathbf{348mL = x}[/tex]
Where x represents the mass of 348mL serving soup.
Cross multiply.
So, we have:
[tex]\mathbf{x \times 290mL = 180g \times 348mL}[/tex]
Cancel out common units
[tex]\mathbf{x \times 290 = 180g \times 348}[/tex]
[tex]\mathbf{x \times 290 = 62640g}[/tex]
Divide both sides by 290
[tex]\mathbf{x = 216g}[/tex]
Hence, the mass of 348mL serving soup is 216 grams
