Determine the answer to 3 + (−5) and explain the steps using a number line and its not -2 because i tried and she said it was wrong my teacher.HELPPP!!!!!!!!!!!

Answers

Answer 1

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.

Oceanside Bike Rental Shop charges 12 dollars plus 7 dollars an hour for renting a bike. Sandy paid 40

Answers

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.

Sara has $1.30 less than double what Billy does. Sara has $53.72. How much money does Billy have?​

Answers

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

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​

Answers

Solving for w by making w the subject of the formula, we would have: D. w = (P - 2l)/2.

Change of Subject of Formula

To 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.

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?

Answers

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

Question 2
64 is 40% of what number?
А
128
B
256
160
D
26

Answers

C: 160 is the correct answer

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

What is the value of x in the figure below? In this diagram, AABD - ACAD

Answers

Answer:

E. √39

Step-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.
