Answer:

a.140

b. -2.6

c. 0

Step-by-step explanation:

a.60-(-80)= 60+80 because two negatives make a positive

=140

b. 2.3+(-4.9)= 2.3-4.9

= -2.6

c. 4.5+(-4.5)=0

Step-by-step explanation:

To estimate the square root of a number, we could start by relating the square to known perfect squares. 125 is between 11 and 12. It is probably closer to 11 since 125 is closer to 121 than to 144.

Answer:

Second option: y = 5(x + 2)

Step-by-step explanation:

Equation that is already graphed: y = 5x - 10

Let's use the second option: y = 5(x + 2)

Since y = 5x - 10,  we substitute 5x - 10 into the equation y = 5(x + 2)

The equation will look like this: 5x - 10 = 5(x + 2)

Now we solve: 5x - 10 = 5(x + 2)

5x - 10 = 5(x + 2)

Distribute

5x - 10 = 5x + 10

Rearrange variables to the left side of the equation

5x - 5x = 10 + 10

Apply the inverse property of addition

0 = 10 + 10

Add 10 and 10

0 = 20

Therefore, there is no solution

Answer:

He rented the bike for 2 hours.

Step-by-step explanation:

Since a bike costs $13 plus $5 per hour, we can write this as:

13 + 5(h)

We used "h" as the variable for hours, since we need to find how many hours he rented the bike for, that he had to pay $23.

And since Pete paid $23, we need to make the other equation equal to 23.

= 23

So the actual equation, would look like this:

13 + 5(h) = 23

Now we just solve for h in the equation:

13 + 5(h) = 23

Step 1: Multipy 5 times "h"

13 + 5h = 23

Step 2: Subtract 13 from both sides

13 + 5h - 13 = 23 - 13

Step 3: Simplify

5h = 10

Step 4: Divide both sides by 5

5h/5 = 10/5

Step 5: Simplify

h = 2

So the number of hours that Pete rented the bike for 2 hours

Answer:

y = 2/3x + 4

Step-by-step explanation:

so we already know the y intercept is 4 so lets put that in the equation

y = mx + 4

now we use the equation y2 - y1 / x2 - x1 to find the slope

lets use the points (-6, 0) and (3, 6)

6 - 0 / 3 - (-6)

6 / 9

2/3

the equation is

y = 2/3x + 4

check:

lets use the point (6, 8)

substitute:

8 = 2/3(6) + 4 ?

8 = 4 +4?

8 = 8

Answer:

20 feet

Step-by-step explanation:

[tex]\frac{80 feet}{40 seconds}[/tex]  = [tex]\frac{x feet}{10 seconds}[/tex]

Simplify [tex]\frac{80}{40}[/tex]

[tex]\frac{80}{40}[/tex] = [tex]\frac{2}{1}[/tex]

Every 1 second, a person will walk 2 feet.

[tex]\frac{x}{10}[/tex] = [tex]\frac{20}{10}[/tex]

X = 20 feet

Answer:

20 feet

Step-by-step explanation:

We can solve this two different ways:

The 1st and easiest way would be to first divide [tex]40/10[/tex] to get [tex]4[/tex], and then divide [tex]80/4[/tex] to get [tex]20[/tex].

This method works well in this situation because all the numbers are easily divisible, but in some situations this method may give you decimals which would make things more difficult.

In a situation like that, you would create a simple equation using this format: [tex]y=m(x)[/tex] in which [tex]y[/tex] represents the total number of feet walked, [tex]m[/tex] represents the number of seconds, and [tex]x[/tex] represents number of feet walked per minute.

You would start by finding out the number of feet walked per minute. You do this by plugging the information you know into the equation. We know that the person walks 80 feet in 40 seconds so the equation would look like this: [tex]80=40x[/tex]

To solve for [tex]x[/tex], you would then divide 40 on both sides to get [tex]2=x[/tex]

Now that we know that the person walks 2 feet every second, we can plug the information into a new equation to find out how far they go in 10 seconds. This equation will look like this: [tex]y=10(2)[/tex] and we can solve it to learn that [tex]y=20[/tex]. This means that the person will walk 20 feet in 10 seconds.

Answer:

Step-by-step explanation:

I'm going to assume it is a rectangle.

P = 2L + 2w = 34

Area = L * w = 60                        Divide by L

w = 60/L                                      Substitute into the perimeter.

P = 2L + 2w = 34                         Put (60/L) for w

P = 2L + 2(60)/L = 34                  Multiply  both sides by L

P = 2L^2 + 120 = 34L                  Subtract 34L from both sides.

2L^2 - 34L + 120 = 0                   Divide everything by 2

L^2 - 17L + 60 = 0                        Factor

(L - 5)(L - 12) = 0

Since L is usually the larger value, use L = 12

L*w = 60

12w = 60

w = 60/12

w = 5

Answer:

D (195,500,000)

Step-by-step explanation:

8.5 mil times 23 equals D

The number of people living in Brazil that year was approximately  195,500,000 people. The answer is the last option 195,500,000 people

From the question, we are to determine the number of people living in Brazil in that year

From the given information,

Brazil land area = 8.5 million square kilometers = 8500000 km²

Brazil population density = Peru population density = 23 people /km²

From population density formula,

[tex]Population\ density = \frac{Number \ of \ people}{Land\ area}[/tex]

Then,

Number of people = Population density × Land area

Therefore,

Number of people living in Brazil = 8500000 × 23

Number of people living in Brazil = 195,500,000 people

Hence, the number of people living in Brazil that year was approximately  195,500,000 people. The answer is the last option 195,500,000 people

Step-by-step explanation:

Answer:

0.2 hours

Step-by-step explanation:

Givens

2/4 mile = 1/2 mile when 2/4 is reduced. 1/2 = 0.5 miles in decimal form.

1/10 = 0.1

0.5 miles        1 mile

Cross multiply

x* 0.5 = 0.1 * 1                        Combine

0.5 x = 0.1                              Divide by 0.5

Answer:

∠ 3 = 35°

Step-by-step explanation:

∠ 5 and ∠ 3 are alternate angles and congruent, thus

∠ 3 = ∠ 5 = 35°

Answer:

24 hours

Step-by-step explanation:

This is because they seem to be stationary about one point on the surface of earth. This is possible when the satellite has the same angular speed as the earth.

This means that it takes the same amount of time to the satellite to take one revolution around the earth as it takes the earth to take one revolution about its axis.

[tex]w=\frac{revolutions}{time}[/tex]

[tex]w_{satellite}=w_{earth}[/tex]

[tex]\frac{N_{satellite}}{t_{satellite}}=\frac{N_{earth}}{t_{earth}}[/tex]

since [tex]N_{satellite}=N_{earth}[/tex]

then, when solving for t we get that:

[tex]t_{satellite}=t_{earth}[/tex]

Answer:

Pigs = 17

Ducks = 6

Step-by-step explanation:

Let there be x pigs and y ducks in the field.

[tex]\implies x + y =23[/tex]

[tex]\implies y =23-x.....(1)[/tex]

Since, there are 80 legs in all.

Each pig has 4 legs and each duck has 2 legs. So, x pigs will have 4x legs and y ducks will have 2y legs.

Total legs = 4x + 2y

Total legs = 80 (Given)

[tex]\implies 4x + 2y =80....(2)[/tex]

From equations (1) & (2), we find:

[tex]\implies 4x + 2(23-x) =80[/tex]

[tex]\implies 4x + 46-2x =80[/tex]

[tex]\implies 2x =80-46[/tex]

[tex]\implies 2x =34[/tex]

[tex]\implies x =\frac{34}{2}[/tex]

[tex]\implies x =17[/tex]

[tex]\implies y =23-17[/tex]

[tex]\implies y =6[/tex]
