Diana decided she needed some new friends to play with. She understood that fish were not fun to hang out with, so she bought 3 baby mice and 2 baby pythons for a total cost of $103.50. Mr. Reyes also thought this was a great idea. He bought 3 baby mice and 3 baby pythons for a price of $148.50. Find the price of the mouse and the price of the python.
Step-by-step explanation:
Let m be the price of 1 baby mice
Let p be the price of 1 baby python
Given,
[tex]3m + 2p = 103.50[/tex]
as equation 1.
and
[tex]3m + 3p = 148.50[/tex]
as equation 2
From here we can easily use elimination method
for solving simultaneous equations.
Use Equation 1 - equation 2 to eliminate m to find p.
[tex](3m - 3m) + (2p - 3p) = 103.50 - 148.50 \\ - p = - 45 \\ p = 45[/tex]
Substitute p into equation 1.
[tex]3m + 2(45) = 103.50 \\ 3m + 90 = 103.50 \\ 3m = 103.50 - 90 \\ 3m = 13.50 \\ m = 13.50 \div 3 \\ = 4.50[/tex]
therefore 1 baby mice cost $4.50 and 1 baby python costs $45.
Answer:
Baby python: $45
Baby mouse: $4.5
Step-by-step explanation:
First of all, 3 baby mice and 2 baby pythons cost $103.50. When Mr. Reyes adds a baby python (He bought 3 baby mice and 3 baby pythons for a price of $148.50.) To find the price of a baby snake, you need to subtract both prices. 148.5-103.5=45, so a baby snake costs $45. Now we need to find the price of the baby mice, so we need to remove the snakes. 45*2=90. (2 snakes). 103.5-90=13.5, and 13.5/3=4.5, so a baby mouse costs $4.5.
Thanks

Answer:
C.
Step-by-step explanation:
Though the story is also about A, B, and D, the overall story is about C. The story begins with the enchanter turning the eldest and second eldest brothers into an Eagle and Whale, though the youngest escapes.

A clerical worker takes 3 times as long to finish a job as it does an executive secretary. Working together, it takes them 4 hr to finish the job. How long would it take the clerical worker, working alone, to finish the job?
Answer:
8 hours
Step-by-step explanation:
In 2 hours, the clerical secretary can do 1/4 of the job. (The executive secretary does 3/4 of the job - or 3 times as much - in the same 2 hours.)
Since it takes the clerical secretary 2 hours to do 1/4 of the job, it will take them four times that to do it themselves. 2x4=8.

Step-by-step explanation:
A tool box has the dimensions of 10 in by 4 in by 3 in. If Andrea plans to double one dimension to build a larger tool box, she believes she would double the volume of the tool box. Is she correct?
Answer: Yes
Step-by-step explanation:
Given
Dimension of the toolbox is [tex]10\ in.\times 4\ in.\times 3\ in.[/tex]
suppose the length of the box is doubled, then a new length will be [tex]2\times 10\ in.[/tex]
So, the volume of the box becomes
[tex]\Rightarrow V=2\times 10\times 4\times 3[/tex]
It can also be written as
[tex]\Rightarrow V=2\times (10\times 4\times 3)=2\times (V_{old})[/tex]
i.e. the volume of the toolbox is doubled. Therefore, Andrea is correct.
A rectangular banner covers an area of 2 7/8ft2. The length of the banner is 3/4ft. What is the width of the banner in ft?
Answer:
Width of the rectangular banner is [tex]3\frac{5}{6}[/tex] ft.
Step-by-step explanation:
Area of the rectangular banner = [tex]2\frac{7}{8}[/tex] square feet
= [tex]\frac{23}{8}[/tex] square feet
Area of rectangle is given by,
Area = Length × Width
Length of the banner = [tex]\frac{3}{4}[/tex] feet
From the formula,
[tex]\frac{23}{8}=\frac{3}{4}\times W[/tex]
W = [tex]\frac{\frac{23}{8} }{\frac{3}{4} }[/tex]
= [tex]\frac{23}{8}\times \frac{4}{3}[/tex]
= [tex]\frac{23}{6}[/tex]
= [tex]3\frac{5}{6}[/tex] ft
Therefore, width of the rectangular banner is [tex]3\frac{5}{6}[/tex] ft

Solve the variable in the following equation: 5 + h = 11 − 2h
A. h = −1
B. h = 2
C. h = 5
D. h = 9
Answer: B. h = 2
Step-by-step explanation:
Given
5 + h = 11 - 2h
Add 2h on both sides
5 + h + 2h = 11 - 2h + 2h
5 + 3h = 11
Subtract 5 on both sides
5 + 3h - 5 = 11 - 5
3h = 6
Divide both sides by 3
3h / 3 = 6 / 3
h = 2
Hope this helps!! :)
Please let me know if you have any questions
Answer:
B) h=2
Step-by-step explanation:
5+h=11-2h
5+h-(-2h)=11
5+h+2h=11
5+3h=11
3h=11-5
3h=6
h=6/3
h=2

+1x=+50
Answer:
x=50
Step-by-step explanation:
+1x=50
divide both sides by 1
x=50
Answer:
x = 50
Step-by-step explanation:
If you divide anything by one, it will remain the same.
To isolate the x variable, you need to divide both sides by 1.
+1x/1 = 50/1
x = 50

find the slope between the given two points
Slope can be found using the following equation:
slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
7) Let:
[tex](x_1 , y_1) = (-1 , -11)\\(x_2 , y_2) = (-6 , -7)[/tex]
Plug in the corresponding numbers to the corresponding variables:
m = [tex]\frac{-7 - (-11)}{-6 - (-1)} = \frac{-7 + 11}{-6 + 1} = \frac{4}{-5} = -\frac{4}{5}[/tex]
Slope: [tex]-\frac{4}{5}[/tex]
8) Let:
[tex](x_1 , y_1) = (-7 , -13)\\(x_2 , y_2) = (1 , -5)[/tex]
Plug in the corresponding numbers to the corresponding variables:
m = [tex]\frac{-5 - (-13)}{1 - (-7)} = \frac{-5 + 13}{1 + 7} = \frac{8}{8} = 1[/tex]
Slope: [tex]1[/tex]
9) Let:
[tex](x_1 , y_1) = (-5 , 3)\\(x_2 , y_2) = (8 , 3)[/tex]
Plug in the corresponding numbers to the corresponding variables:
m = [tex]\frac{3 - (3)}{8 - (-5)} = \frac{0}{8 + 5} = \frac{0}{13} = 0[/tex]
Slope: [tex]0[/tex]
10) Let:
[tex](x_1 , y_1) = (3 , -2)\\(x_2 , y_2) = (15 , 7)[/tex]
Plug in the corresponding numbers to the corresponding variables:
m = [tex]\frac{7 - (-2)}{15 - 3} = \frac{7 + 2}{15 - 3} = \frac{9}{12}[/tex]
Simplify the slope. Divide common factors from both the numerator and denominator:
[tex](\frac{9}{12})/(\frac{3}{3} ) = \frac{3}{4}[/tex]
Slope: [tex]\frac{3}{4}[/tex]
11) Let:
[tex](x_1 , y_1) = (-5 , -10)\\(x_2 , y_2) = (-5 , -1)[/tex]
Plug in the corresponding numbers to the corresponding variables:
m = [tex]\frac{-1 - (-10)}{-5 - (-5)} = \frac{-1 + 10}{-5 + 5} = \frac{9}{0} =[/tex] undefined.
Slope: undefined
12) Let:
[tex](x_1 , y_1) = (-4 , -2)\\(x_2 , y_2) = (-12, 16)[/tex]
Plug in the corresponding numbers to the corresponding variables:
m = [tex]\frac{16 - (-2)}{-12 - (-4)} = \frac{16 + 2}{-12 + 4} = \frac{18}{-8} = -\frac{18}{8} = ((-\frac{18}{8})/( \frac{2}{2}) = -\frac{9}{4}[/tex]
Slope: [tex]-\frac{9}{4}[/tex]
