Laura has 10 more marbles than Kristen
128-188=10
1/2(x+6)=2x
1/2x + 3 = 2x
x + 6 = 4x
3x = 6
x = 2
5-2x+7x-h
5-2(2)+7(2) = h
h = 5 - 4 + 14
h = 1 + 14
h = 15
Answer:
x = 3.873 units
or x =
units
Step-by-step explanation:
Hypotenuse = 4 , x = height of this isosceles triangle.
base is 2,
so Use Pythagorean Theorem.
x^2 + 1^2 = 4^2
x^2 = 4^2 - 1^2
x^2 = 16 - 1 = 15
x = root(15) =
-2.31-(-5.9)= -2.31+5.9= 3.59
