Let's solve your equation step-by-step.

7x+3+x+55=14x−5+x

Step 1: Simplify both sides of the equation.

7x+3+x+55=14x−5+x

7x+3+x+55=14x+−5+x

(7x+x)+(3+55)=(14x+x)+(−5)(Combine Like Terms)

8x+58=15x+−5

8x+58=15x−5

Step 2: Subtract 15x from both sides.

8x+58−15x=15x−5−15x

−7x+58=−5

Step 3: Subtract 58 from both sides.

−7x+58−58=−5−58

−7x=−63

Step 4: Divide both sides by -7.

−7x

a force of 10 newtons acts in a direction 75 above horizontal moving an object 15 meters from (0,0) to (15,0). What is the work done by the force?
a. 2.59 joules
b. 3.88 joules
c. 38.82 joules
d. 150.00 joules

Answers

Answer:

150 Joules

Step-by-step explanation:

Step one:

Given data

Force F= 10N

the distance is described by the coordinate =  (0,0) to (15,0)

hence the distance = 15m in the x-direction.

Step two:

Required is the work done

we know that work done is expressed as

Wd= Force* Distance

Wd= 10*15

Wd= 150 Joules

What do the differences between the points (as shown on the graph) represent? On a coordinate plane, point B is at (2, 7) and point D is at (4, 14). StartFraction 7 over 2 EndFraction is the unit rate because it compares the change in y-values to the change in x-values of the points on the graph. StartFraction 2 over 7 EndFraction is the unit rate because it compares the change in y-values to the change in x-values of the points on the graph. StartFraction 7 over 2 EndFraction can be used to find the unit rate if one divides 7 by 2 and compares the result to 1. StartFraction 2 over 7 EndFraction can be used to find the unit rate if one divides 2 by 7 and compares the result to 1.

Answers

Answer:

StartFraction 7 over 2 EndFraction can be used to find the unit rate if one divides 7 by 2 and compares the result to 1

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

we have the points

B(2, 7) and D(4, 14)

substitute the values

The unit rate is

therefore

StartFraction 7 over 2 EndFraction can be used to find the unit rate if one divides 7 by 2 and compares the result to 1

The length of a rectangle is four times its width.
If the area of the rectangle is 144 ft, find its perimeter.

Answers

Answer:

y = mx + c

since m = 0

c = 9

Answer: 60

suppose: the width of a rectangle is x (x > 0)

⇒ The length of a rectangle is 4x

because  the area of the rectangle is 144 ft

=> 4x.x = 144

⇔ x² = 144/4 = 36

⇒ x = 6

with x = 6 ⇒ The length of a rectangle is 4.6 = 24

the perimeter of the rectangle is (6 + 24).2 = 60

Answer:

k=-5,5

Step-by-step explanation:

first you calculate (by switching  the -6 to the other side)

|k|<-1+6

second you add the -1+6 and get |k|<5

the other part will be that the |k| will turn to - negative.

now you will have -k<5 then not you have to take the negative of -k to only have, (k<-5), k equalling to -5.

But remeber you always flip the < to > when you have the greater-to-equal sign or less-to-equal sign.

Answers

Answer:

In this problem, we use the formula for volume which is:  

volume=(length*width*height)/3

Since the base of the triangle is a square, we simply know that the length and width is equal.

L = W = 2 ft

H = 6 ft

Solution:

V = (2*2*6)/3V = 8 ft^3

The correct answer is 8 ft^3
