Let
x = points that a student needs to score on a test
p = points worth the exam.
to find how many points to student needs to score on a test to get a test score of 78%. it will be given by
x = 0.78 * p
Thus, in a 50-point test, the number of points the student needs to get to get a test score of 78% will be
x = 0.78 * 50 = 39 points.
You get the hypothenuse by doing √a²+b² = c
So....
Square both terms
x² + (3x+3)² = 625
x² + 9x² + 18x + 9 - 625 = 0
10x² + 18x - 616 = 0
x₁,₂ = (-b±√Δ)/2a
Δ = b²-4ac
You call a 10, b 18 and c -616
x1,2 = (-18±√18²-4*10*-616)/2*10
x1,2 = (-18±√324+24640)/20
x1,2 = (-18±√24964)/20
x1,2 = (-18<span>±158)/20
x1 = -18+158/20 = 140/20 = 7
x2 = (-18-158)/20 = -176/20 = -44/5
Pick the first solution
So one leg is 7 and the other is 3(7+1) = 3(8) = 24
Let's verify </span>√24²+7² = √576+49 = √625 = 25

Answer:
y=10.75
Step-by-step explanation:
46 + 1) + y = 5(y - 1) +9
47+y=5y-5+9
47+y=5y+4
Collect like terms
47-4=5y-y
43=4y
Divide by 4
43/4=4y/4
43/4=y
y=10.75
