Eva's new bunny weighted 1 7/8 pounds when she first got him 4 weeks ago. Now he weighs 2 1/4 pounds. How much weight has Eva's dog actually gained
Answers
Answer: Eva's dog actually gained 3/8 pounds ( 0.375pounds)
Step-by-step explanation:
Step 1
Given that
old weight = 1 7/8 pounds
New weight = 2 1/4 pounds
weight gained = New weight - Old weight
Step 2
weight gained = New weight - Old weight
2 1/4 pounds - 1 7/8 pounds
2.25 pounds - 1.875 pounds
0.375pounds = 3/8 pounds

Answers
Answer:
(8, - 5 )
Step-by-step explanation:
Given the 2 equations
3x + 4y = 4 → (1)
- x - 3y = 7 → (2)
Multiplying (2) by 3 and adding to (1) will eliminate the x- term.
- 3x - 9y = 21 → (3)
Add (1) and (3) term by term to eliminate x, that is
0 - 5y = 25
- 5y = 25 ( divide both sides by - 5 )
y = - 5
Substitute y = - 5 into either of the 2 equations and solve for x
Substituting into (1)
3x + 4(- 5) = 4
3x - 20 = 4 ( add 20 to both sides )
3x = 24 ( divide both sides by 3 )
x = 8
solution is (8, - 5 )

Answer:
[tex]y = \frac{1}{2} x + \frac{1}{2} [/tex]
Step-by-step explanation:
equation of line formula:
[tex]y = mx + c[/tex]
m = slope
c = y-intercept
1) find m
slope formula:
[tex]m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1}} [/tex]
take 2 coordinates from the given graph and substitute the values into the slope formula
i) (-1,0)
[tex]x _{1} = - 1[/tex]
[tex]y_{1} = 0[/tex]
ii) (3,2)
[tex]x_{2} = 3[/tex]
[tex]y_{2} = 2[/tex]
substitute the values into the slope formula
[tex]m = \frac{2 - 0}{3 - ( - 1)} [/tex]
[tex]m = \frac{2}{4} [/tex]
[tex]m = \frac{1}{2} [/tex]
2) find the half equation of the line by substituting the value of m into the equation of line formula
[tex]y = \frac{1}{2} x + c[/tex]
3) find c by substituting either coordinate into the half equation
(3,2)
x = 3
y = 2
[tex]2 = \frac{1}{2} (3) + c[/tex]
[tex]2 = \frac{3}{2} + c[/tex]
[tex]2 - \frac{3}{2} = c[/tex]
[tex] \frac{1}{2} = c [/tex]
[tex]c = \frac{1}{2} [/tex]
4) find equation of line by substituting the value of c into the half equation
[tex]y = \frac{1}{2} x + \frac{1}{2} [/tex]

If FE is a midsegment of ABCD, find DF.

Answers
Answer:
C
Step-by-step explanation:
Remark
A midsegment is 1/2 the size of the side that it is parallel to.
Equation
6x - 6 = 2*(x + 3) Remove the brackets
6x - 6 = 2x + 6 Subtract 2x from both sides
6x - 2x - 6 = 6 Combine
4x - 6 = 6 Add 6 to both sides
4x = 6 + 6 Combine
4x = 12 Divide by 4
x = 12 / 4
x = 3

• 12 students want a beef meal. • 8 students want a chicken meal. • 5 students want a pasta meal. Based on the survey results, which of these is the best prediction of the meals wanted by the 200 students?
Answers
Answer: See explanation
Step-by-step explanation:
You didn't give the options but let me help out.
Number of students that want a beef meal = 12
Number of students that want a chicken meal = 8
Number of students that want a pasta meal = 5
Total number of students = 12 + 8 + 5 = 25
The prediction of the meals wanted by the 200 students will be:
Beef meal = 12/25 × 200 = 96
Chicken meal = 8/25 × 200 = 64
Pasta meal = 5/25 × 200 = 40
A Verizon salesman sold $5,750 in sales last week. He made $230 in commission. What percent commission did he make?
Answers
The answer is: 4%
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 5750 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 5750, so we can write it down as 100%=5750.
4. We know, that x% equals 230 of the output value, so we can write it down as x%=230.
5. Now we have two simple equations:
1) 100%=5750
2) x%=230
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=5750/230
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 230 is what percent of 5750
100%/x%=5750/230
(100/x)*x=(5750/230)*x - we multiply both sides of the equation by x
100=25*x - we divide both sides of the equation by (25) to get x
100/25=x
4=x
x=4
now we have:
230 is 4% of 5750
