Answer:
The formula for surface area of a right triangle is A = b∙h2 where b is base and h is height.
y=13
Step-by-step explanation:
y=3x-5
y=3(6)-5
y=18-5
y=13
again, we're assuming that both triangles are similar, and thus using proportions.

we do not use the -10, because whatever value "x" may be, can't be negative or even 0.
Answer:
A $2000
Step-by-step explanation:
Let x be the least amount of money the club has to make to get $600 then...
30%x=600
We can convert 30% to a fraction. Any percentage is that number percent over hundred:

Simplify the fraction by dividing it by 10/10. Notice we can only do this since 10/10 is equivalent to 1, so in a sense we are dividing the fraction by 1:

Multiply 10 to both sides

Divide both sides by 3

The club would have to make at least $2000
