First, you have to simplify the equation:
y+3 = 3(x+5)
y+3=3x+15
So you multiply what’s inside the brackets (x+5) by the factor (3). So 3•x=3x, 3•5=15.
Then you rearrange the equation as necessary to convert it into standard form, which is Ax + By = C

Answer:
B SSA
Step-by-step explanation:
Geometric proofs can be used to show that the two triangles are congruent using ASA, SAS and SSS.
However, there is no such thing as SSA in geometry because an angle and two sides can not show congruence of triangles. This is so because the angle is not an included angle.
Answer:
6.25 minutes
Step-by-step explanation:
First, let's simplify it down. We want to find out how many shirts she can fold in 1 minute, then multiply that by 50.
20 shirts in 2.5 minutes
20 shirts = 2.5 minutes
An equals sign is like a see-saw. If you do something to one side, you have to do it to the other side. To get 20 shirts to 1 one shirt, divide by 20. You have to do that to the other side to make it equal.
(20 divided by 20) = (2.5 divided by 20)
1 shirt = 0.125 minutes.
That's how long it takes to fold 1 shirt. To find the time for 50 shirts, multiply that by 50.
0.125 x 50 = 6.25
It will take Carrie 6.25 minutes to fold 50 shirts. Hope this helped =)
