The correct answer is 5b + 1 = 3b + 5. In order to find the answer to a system of equations, the two equations must be set equal to each other. For instance, if we had the equations x = y + 1 and x = 3y - 1, we would set the two equations equal to one another to find the answer.

x = y + 1
x = 3y - 1
y + 1 = 3y - 1
1 = 2y - 1
2 = 2y
1 = y

x = y + 1
x = 1 + 1
x = 2

You can use the same procedure with this system of equations.

5b + 1 = 3b + 5
2b + 1 = 5
2b = 4
b = 2

a = 5b + 1
a = 5(2) + 1
a = 10 + 1
a = 11

Hope this helps!

Answer:

C. 5b+1=3b+5

Step-by-step explanation:

We have been given a set of equations as:

Equation A: a=5b+1

Equation B: a=3b+5

We can see that the given set of equations represent system of linear equation.

We will use substitution property of equality, which states when x=y, then x can be substituted in any equation in place of y and y can be substituted in place of x in any equation as well.

To solve our given system of equations we need to equate our given equations as:

5b+1=3b+5

Therefore, option C is the correct choice.

Answer:

(x-1)^2+(y+4)^2=9

Step-by-step explanation:

The equation of a circle is given by:

(x-h)^2+(y-k)^2=r^2

Where (h, k) is the center and r is the radius.

The center of the circle is (1, -4).

And the radius is 3.

Substitute:

(x-(1))^2+(y-(-4))^2=(3)^2

Simplify. Thus, our equation is:

(x-1)^2+(y+4)^2=9

Which expression is equivalent to 5a+20? A: 5(5a+4). B: 5(a+4). C: 5(a+20). D: 5(a+1)
guajiro [1.7K]

Answer:

5(a+4)

Step-by-step explanation:

expression is equivalent to 5a+20

To get the equivalent expression we need to factor the given expression

5a+ 20

5a can be written as 5 * a

20 can be written as 5*2*2

WE can see that common factor is 5 for both 5a and 20

So GCF is 5

Now we factor out GCF 5

WE put 5 outside and write all the left of factors inside the parenthesis

5a +20

5 (a+2*2)

5(a+4)
