Suppose you receive an allowance of $70 and your friend receives an allowance of $54 at the beginning of
the month. If you spend $5 a day and your friend spends $3 a day, after how many days will you and your
friend have the same amount of money?
Answer:
after 9 days
Step-by-step explanation:
day 1
you: 70
friend: 54
day 2
you: 65
friend: 51
day 3
you: 60
friend: 48
day 4
you: 55
friend: 45
day 5
you: 50
friend: 42
day 6
you: 45
friend: 39
day 7
you: 40
friend: 36
day 8
you: 35
friend: 33
day 9
you: 30
friend: 30
Answer:
8 days
Step-by-step explanation:
x=days
70 - 5x = 54 - 3x
-54 +5
16 = 2x
8 = x
Check:
you friend
70 - 5 x 8 = 30 | 54 - 3 x 8 = 30
70 - 40 = 30 | 54 - 24 = 30
30 = 30 | 30 = 30

#8. Solve: 4x - 5 + 2x = 7
x = 12
x= 1/3
x = 6
x=2
Answer:
x = 2
Step-by-step explanation:
4x - 5 + 2x = 7
6x - 5 = 7
6x -5 + 5 = 7 + 5
6x = 12
6x / 6 = 12 / 6
x = 2

Find the distance between the points with coordinates (-9,8) and (3,6). Round your answer to the nearest tenth.
Answer:
The answer is
12.2 unitsStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x_1 - x_2})^{2} + ({y_1 - y_2})^{2} } \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-9,8) and (3,6)
The distance between them is
[tex]d = \sqrt{ ({ - 9 -3 })^{2} + ({8 - 6})^{2} } \\ = \sqrt{ ({ - 12})^{2} + {2}^{2} } \\ = \sqrt{144 + 4} \\ = \sqrt{148} \: \: \: \: \: \: \: \: \\ = 2 \sqrt{37} \: \: \: \: \: \: \: \: \\ = 12.1655...[/tex]
We have the final answer as
12.2 unitsHope this helps you

given: 6g+4a=7a
prove: g/a=1/2
Answer:
Step-by-step explanation:
6g + 4a = 7a
⇔ 6g = 7a - 4a
⇔ 6g = 3a
Divide both side by 6a
⇒ [tex]\frac{6g}{6a} = \frac{3a}{6a}[/tex] ⇔ [tex]\frac{g}{a} = \frac{1}{2}[/tex]

f(x) = 12x + 5
find f(11)
f(11) =
F(11) means to replace x in the equation with 11
12(11) + 5
12 x 11 = 132
Now you have 132 + 5 = 137
F(11) = 137
a recipe for cookies requires two-thirds of a cup of butter. rama wants to make 3/4 of the recipe. how many cups of of butter should she use to make cookies.
Answer:
[tex] \frac{1}{2} \: cups[/tex]
Step-by-step explanation:
Butter required for one recipe of cookies
[tex]= \frac{2}{3} [/tex] cup
Therefore,
Butter required for [tex] \frac{3}{4} [/tex] recipe of cookies
[tex]= \frac{3}{4} \times \frac{2}{3}\\\\
= \frac{1}{2} \times \frac{1}{1}\\\\
= \frac{1}{2} \: cups[/tex]
the area of a rectangle 54 cm2. and its length =9cm. find :
A) tge widtg of the rectangle.
B) the ratio between the width of the rectangle and its length.
C) the ratio beetween the width of the rectangle and its perimeter.
Answer:
A) 6cm
B) 2:3
C) 1:5
Step-by-step explanation:
A) area of rectangle = width × length
54cm^2 = x × 9
x = 54 ÷ 9
width = 6cm
B) the width = 6cm
the length = 9cm
the ratio between the width and the length
=》6cm : 9cm
if you simplify, it becomes 2: 3
C) the perimeter of the rectangle
= (2 × width) + (2 × length)
= (2 × 6) + (2 × 9)
= 12 + 18
= 30 cm
the ratio between the width and the perimetet
=》 6cm : 30 cm
if you simplify, it becomes 1 : 5

1. At Parker’s Pizza Parlor, the total cost of an order of 5 slices of pizza is $12.37. This price includes $1.12 in sales tax. Let p represent the cost of 1 slice of pizza. (a) Write an equation to represent this scenario. (b) Solve the equation for p to determine the cost of 1 slice of pizza.
Step-by-step explanation:
p = 5 ÷ (12.37 - 1.12)
p = 5 ÷ 11.25
p = 2.25
Answer:
$12.37-1.12=$11.25
let p =1 slice
5(p)=11.25
5p=11.25
=2.25Question 2
Austin needs a total of $350 to buy a new bicycle. He has $35 saved. He earns $15 each week delivering
newspapers. How many weeks will Austin have to deliver papers to have enough money to buy the bicycle?
Answer:
21 weeks
Step-by-step explanation:
Equation: y = 15x + 35
15 is the rate of change and 35 is the starting point
Lets replace y with 350 since that the goal
350 = 15x + 35
Subtract 35 from both sides;
315 = 15x
Divide both sides by 15;
x = 21
He will have to deliver papers for 21 weeks to have enough money to buy a new bicycle.
360 = 37.50x + 60 solve for x

please help me my teacher already mad!!
Answer:
1. D
2. A
3. -1/3
4. 1/2
5. 2/3
Answer(s):
1. C. The graph has a slope of 0. (The slope is the change in the value of y over the change in the value of x--also known as rise over run--and there is no "slope" in this horizontal line. Think of slope like the steepness of a hill. If there is no steepness, then there is no slope.)
2. A. The graph decreases from left to right. (A negative slope is doing down a hill while positive is going up. So, if it's going down, then it's decreasing from left to right. Draw it out to better understand it if you're still confused.)
3. m = [tex]-\frac{1}{3}[/tex] (Slope is rise over run. If the y is going down, it's a negative change. If up, then positive. For the x, if it's going to the right--or forwards, if your think about it, then it's positive and negative when going towards the negative left side. In this graph, the y decreases by one and the x increases by three. x/y would result in -1 over 3.)
4. m = [tex]\frac{1}{2}[/tex] (If there are no plotted points for you, just pick two points from the graph! Find the change in y and the change in x, put it in the format m = y/x and simplify if needed.)
5. m = [tex]\frac{2}{3}[/tex] (Like in no. 4, find the changes in y over x. Then, simplify if needed. For example, the rise over run of two points I found was 4/6, which is 2/3.)

Write a two-column proof. Given: line BD bisects angle CBE. Prove: angle ABD approximately equal to angle FBD.
Answer:
The proof is derived from the summarily following equations;
∠FBE + ∠EBD = ∠CBA + ∠CBD
∠FBE + ∠EBD = ∠FBD
∠CBA + ∠CBD = ∠ABD
Therefore;
∠ABD ≅ ∠FBD
Step-by-step explanation:
The two column proof is given as follows;
Statement [tex]{}[/tex] Reason
[tex]\underset{BD}{\rightarrow}[/tex] bisects ∠CBE [tex]{}[/tex] Given
Therefore;
∠EBD ≅ ∠CBD [tex]{}[/tex] Definition of angle bisector

3) Then the machine is broken
4) It could be a malfunction
5) No, someone messed up the stickers
6) Them the machine is working
Answer:
5. kitkat
6. B4
7. the machine was either switching between snacks or its a malfunction. stickers also may have been messed with
8. possibly? im not sure what the question is exactly asking but i would assume so
9. no it just means snacks are in two different places but sometimes yes it could be a malfunction
10. then it is not a problem. they use the same input and get the same output.
