Step-by-step explanation:
25 questions, 2 points each.
that means there were 25×2 = 50 points in total.
Gideon got 42 out of the 50.
100% = 50
1% = 100%/100 = 50/100 = 0.5
42 is how many % ? as many as 1% (0.5) fits into 42.
so,
42/0.5 = 42×2 = 84%
he scored 84%.
Answer:
Step-by-step explanation:
Multiply the numbers 2 ( x - 11 ) * 2 = 128
4 ( x - 11 ) = 128
Distribute 4 ( x - 11 ) = 128
4x - 44 = 128
Add 44 to both sides 4x - 44 = 128
4x - 44 + 44 = 128 + 44
Simplify - Add the numbers
4x - 44 + 44 = 128 + 44
4x = 128 + 44
- Add the numbers
4x = 128 + 44
4x = 172
Divide both sides by the same factor 4x = 172
4x/4 = 172/4
Simplify
- Cancel terms that are in both the numerator and denominator
4x/4 = 172/4
x = 172/4
-Divide the numbers
x = 172/4
x = 43
Answer:
y-4=-2(x+1)
Step-by-step explanation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(-4-4)/(3-(-1))
m=-8/(3+1)
m=-8/4
m=-2
y-4=-2(x-(-1))
y-4=-2(x+1)
