Answer:

$40.40

Step-by-step explanation:

1. Round each decimal to the nearest tenth. Keep in mind that the sum is the answer to an addition problem.

$4.28 = $4.30

$21.35 = $21.40

$14.65 = $14.70

2. Now, all we have to do is add up the three decimals to find the answer.

$21.40 + $14.70 + $4.30 = $40.40

Conclusion: Your answer is $40.40

Answer:

Step-by-step explanation:

Question 1: C

1 multiplied by 5 = 5

1 plus 5 = 6

So you get: (x+5)(x+1) which means x = -5 or -1

Question 2: B

2 multiplied by -4 = - 8

2 plus -4 = -2

So you get: (x-4)(x+2) which means x = 4 or -2

Can someone solve 5 + 2x = + 6<br><br> and n - 3n = 14 - 4n<br><br> and 7 ( 5a - 4 ) - 1 = 14 - 8a

professor190 [17]

Answer:

5 + 2x = 6

2x = 6-5

2x = 1

x = 0.5

n -3n = 14 -4n

-2n = 14-4n (since 4n is negative, change the sign to make it positive and then add 4n to both sides of the equation)

2n = 14

n = 7

7 (5a - 4) - 1 = 14 - 8a

35a - 28 - 1 = 14 -8a

35a -29 = 14 - 8a

43a = 43

a = 1

Find Distance (4,6) (-4,-3)

vampirchik [111]

Answer:

$\sqrt{145}$

Step-by-step explanation:

The distance formula states that the distance between two points $(a,b)$ and $(c,d)$ is $\sqrt{(a-c)^2+(b-d)^2}$ .

The two points we have are $(4,6)$ and $(-4,-3)$ . Plugging these numbers into the distance formula, we have

$\sqrt{(4-(-4))^2+(6-(-3))^2$ .

Simplifying with order of operations, first using the distributive property, gives

$\sqrt{(4+4)^2+(6+3)^2$ .

Squaring and adding gives

$\sqrt{(4+4)^2+(6+3)^2}=\sqrt{8^2+9^2}\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\sqrt{64+81}\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\boxed{\sqrt{145}},$

which is the answer in simplest form. This also rounds to about 12.04.
