Step 1: Rewrite the equation

7(x+4)-6(x+3)=x+5

Step 2: Distribute

7(x+4)- 6(x+3) = x+5

7x+28-6x-18 = x+5

Step 3: Combine like terms

7x+ 28 -6x-18 = x+5

x+10=x+5

Step 4: To seclude x, subtract 5 on both sides (we choose 5 instead of 10, to avoid working with negatives)

x+10=x+5
-5 -5
________
x+5=x

Step 4: Subtract x on both sides

x+5=x
-x -x

5=0x

Step 5: Your answer (if I did this correctly) is 0

Hope this is right and it helps :)

Area of circle with diameter of 1 m?
Elena-2011 [213]

Answer:

A = 0.785m²

B = 31400cm²

C = 7850cm²

D = 785,000mm²

Step-by-step explanation:

To solve this question, we'll have to find the area of a circle which is

Area of a circle = πr²

1. The diameter of the circle = 1m

Area of a circle = πr²

r = radius of the circle

π = 3.14

Radius = diameter / 2

Radius = 1 / 2 = 0.5m

Area = 3.14 × (0.5)²

Area = 3.14 × 0.25

Area = 0.785m²

2. Radius = 100cm

Area of a circle = πr²

Area = 3.14 × (100)²

Area = 3.14 × 10000

Area = 31400cm²

3. Diameter = 100cm

Area = πr²

Radius = diameter / 2

Radius = 100 / 2

Radius = 50cm

Area = πr²

Area = 3.14 × (50)²

Area = 3.14 × 2500

Area = 7850cm²

4. Radius = 500mm

Area = πr²

Area = 3.14 × (500)²

Area = 3.14 × 250,000

Area = 785,000mm²

Could the value of x in the figure below be 10?
RSB [31]

Answer:

It cannot

Step-by-step explanation:

The hypotenuse is always the longest side, which in this instance of the left triangle, it is 14

If x were to be 10, this would make line KM to be 15 units long,  (10 + 5)

Despite line LM being unknown, x must have a number below 10 (, and 9) to make it possible
