How many solutions does -46+23=46x+23
Slav-nsk [51]

Answer:

x = -1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−46+23=46x+23

(−46+23)=46x+23(Combine Like Terms)

−23=46x+23

−23=46x+23

Step 2: Flip the equation.

46x+23=−23

Step 3: Subtract 23 from both sides.

46x+23−23=−23−23

46x=−46

Step 4: Divide both sides by 46.

46x/46 = -46/46

A shipping company uses an inclined conveyor belt to load or unload packages. The dock is 15 feet above ground. The base of the
alexgriva [62]
Hey there! :D

Think of this like a triangle. The dock is 15 feet above ground. It is the side of the triangle. The line connecting the bottom of the dock to the base of the conveyor belt is 40 feet. This is like the base. 

The conveyor belt itself is at a diagonal, and should be the hypotenuse. 

Use the Pythagorean theorem. 

a^2+b^2=c^2

15^2+40^2= c^2 

225+1,600= c^2

Add the values together. 

1,825= c^2

Find the square root of 1,825. 

c= 42.7 (rounded to the nearest tenth) 

The conveyor belt is 42.7 feet long.

I hope this helps!

Help with this pls?????
Alenkinab [10]

Answer:

83.74 in squared

Step-by-step explanation:

The area of the original rectangle is: 14 * 8 = 112 in squared.

The area of a circle is \pi r^{2}, where r is the radius. In this case, we know the diameter is 6, so the radius is 3. Then, the area of the circle is:

3.14 * 3^2 = 3.14 * 9 = 28.26 in squared.

The remaining area is just the total minus the circle area:

112 - 28.26 = 83.74 in squared
