Explain how to find the sum of 3/10 + 4/100
Neporo4naja [7]

Answer: 17/50

Step-by-step explanation:

First, to add fractions, we must find a common denominator, in this case, 100.

Then, we must make the fractions being added all have the common denominator.

So, we must multiply 3/10 * 10/10, which equals 30/100

30/100 + 4/100

Then, just add across the numerator to get 34/100, which can be simplified to 17/50

Solve the following system of equations.
Elan Coil [88]

Answer:

(2,-3)

Step-by-step explanation:

I am not sure if you meant the first equation to be y or -y.  I solved it as y.

y = x-5                       -x -3y =7

I am going to take the second equation and write it as x =

-x - 3y = 7  Give equation

-x = 3y +7   Add 3y to both sides

x = -3y-7  Multiplied each term in the equation by -1 so that x could be positive

I am going to substitute -3y-7 for x in the first equation up above

y = x - 5

y = -3y -7 - 5  Substitute -3y-7 for x

y = -3y -12  Combined -7-5

4y = -12  Added 3y to both sides

y = -3  Divided both sides by 4.

I now know that y is -3, I will plug that into x = -3y-7 to solve for x

x = -3(-3) -7

x = 9-7   A negative times a negative is a positive

x = 2

can anyone help me and show work for this Find the length of the third side. If necessary, write in simplest radical form.
tiny-mole [99]

Answer:

Step-by-step explanation:

Use Pythagorean theorem

Hypotenuse² = base² + altitude²

                      = 9² + 10²

                      = 81 + 100

                      = 181

hypotenuse = √181

Graph the line with slope 3/2<br> and y-intercept - 7.
Ronch [10]

Answer:

14=3x-2y

y = m x+ c \\ y =  \frac{3}{2} x - 7 \\ y =  \frac{3x - 14}{2}  \\ 2y = 3x - 14 \\ 14 = 3x - 2y \\ therefore \\ 14 = 3x - 2y \: is \: the \: required  \: eqution \: of \: the \: line

it can be wrong also

Hey there!

Here;

Diameter (d) = 13 ft

Radius (r) = 13/2 = 6.5 ft

Now,

Area of a circle= πr²

= (22/7)*(6.5)²

= 132.78 ft²

Therefore, the area is 133 ft².
