Answer:
-2
Step-by-step explanation:
Here is a number line:
<-------+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+------>
-6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6
Start at 3, marked with an S below:
<-------+-----+-----+-----+-----+-----+-----+-----+-----+-----S----+-----+-----+------>
-6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6
Since you are adding a negative number, -5, count 5 numbers to the left starting on P which corresponds to 3.
5<---4<---3<----2<---1<---Start
<-------+-----+-----+-----+-----E-----+-----+-----+-----+-----S----+-----+-----+------>
-6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6
You end up at E which corresponds to -2.
Therefore, -5 added to 3 is -2.
I don't know how your teacher can say that 3 + (-5) is not -2 since -2 is the correct answer. Perhaps you should check on the question to make sure it really is 3 + (-5) and not something else.
Three boys cut out hundredths decimal models. Luke shades three fourths of one model. Owen shades four small squares of one model. Jacob shades two full models and nine tenths of another model. What decimal represents the amount each boy shades?
Answer:
Luke = 0.75
Owen = 0.04
Jacob = 2.9
Step-by-step explanation:
A model = 100 small squares
100 small squares = 1
Luke shades three fourths of one model.
Luke = 3/4 of 1 model
= 3/4 × 1
= 0.75
Owen shades four small squares of one model.
Owen = 4/100
= 0.04
Jacob shades two full models and nine tenths of another model
Jacob = 2 + 9/10
= 2 + 0.9
= 2.9
Luke = 0.75
Owen = 0.04
Jacob = 2.9

Answer:
x = 20, y = 110
Step-by-step explanation:
For x:
[tex]5x + 45 + 3x - 25 = 180\\8x + 20 = 180\\8x = 160\\x = 20[/tex]
For y:
[tex]y + 2x - 5 + 3x - 25 = 180\\y + 2(20) - 5 + 3(20) - 25 = 180\\y + 40 - 5 + 60 - 25 = 180\\y + 35 + 35 = 180\\y + 70 = 180\\y = 110[/tex]

W2 = 46
Step-by-step explanation:
W^2 = 46.
We know that 6^2 = 36 and 7^2 = 49.
Therefore W should be between 6 and 7.

Oceanside Bike Rental Shop charges 12 dollars plus 7 dollars an hour for renting a bike. Sandy paid 40
dollars to rent a bike. How many hours did she pay to have the bike checked out?
x = # of hours the bike was rented.
$40 = $12 + $7x
Subtract $12 from both sides.
$28 = $7x
Divide both sides by $7
4 = x
Sandy rented the bike for 4 hours.
which equation shows P=2l + 2w when solved for w?
A. w= 2l/P
B. w= 2l-P/2
C. w=2l - p/2
D. w=p-2l/2
Solving for w by making w the subject of the formula, we would have: D. w = (P - 2l)/2.
Change of Subject of FormulaTo make a variable a subject of the formula, we solve for the variable.
Given the equation, P=2l + 2w, we are required to solve for w.
Thus:
P = 2l + 2w
Subtract both sides by 2l
P - 2l = 2w
Divide both sides by 2
(P - 2l)/2 = w
w = (P - 2l)/2
Therefore, solving for w by making w the subject of the formula, we would have: D. w = (P - 2l)/2.

Sara has $1.30 less than double what Billy does. Sara has $53.72. How much money does Billy have?
Answer:
Billy has $27.51
Step-by-step explanation:
First let's set up an equation to solve this problem.
Assign a variable to Billy's amount. Let's make it x.
Then we just interpret the problem and solve:
2x - 1.30 = 53.72
+1.30 +1.30
----------------------------
2x = 55.02
(Divide by 2 on both sides)
----------------------------
x = $27.51
2x = Billy's amount doubled
2x - 1.30 = Taking away 1.30 from double Billy's amount
53.72 = Sara's amount

What is the value of x in the figure below? In this diagram, AABD - ACAD
Answer:
E. √39Step-by-step explanation:
see attached
From the similar triangles value of x is √39. Therefore, option E is the correct answer.
From the given triangle, CD=13, BD=3 and AD=x.
Given that, ΔABD is similar to ΔCAD.
CD/AD = AD/BD
13/AD = AD/3
39 = AD²
AD = √39 = x
Therefore, option E is the correct answer.

Question 2
64 is 40% of what number?
А
128
B
256
160
D
26
Answer:
answer is 160
Step-by-step explanation:
1. We assume, that the number 40 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 40, so we can write it down as 100%=40.
4. We know, that x% equals 64 of the output value, so we can write it down as x%=64.
5. Now we have two simple equations:
1) 100%=40
2) x%=64
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%=40/64
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 64 is what percent of 40
100%/x%=40/64
(100/x)*x=(40/64)*x
100=0.625*x
100/0.625=x
160=x
x=160
now we have:
64 is 40% 160

Answer:
I also just noticed that is saying construct a segment of the lenght of both of them so after you have both lenght measure them draw AB close point get CD and trace it over start from B and there you have the big segment which is made of both of them AB + CD
:)
Step-by-step explanation:
So basically get your compass and start by these steps
first get the total lenght of AB lets say its 100
when you go to make CD angle all you have to do
its trace same line and there you got both points same sizes
