D= difference in height
A= Alex's height (1.6m) N= Noah's height (1.5A)
Step 1:
D=N-A
substitute N= 1.5 A in for N
D= 1.5(1.6) - 1.6
D= 2.4 - 1.6
D= 0.8 m difference in height
Step 2:
Convert meters to centimeters 1 m = 100 centimeters
0.8 x 100-80cm
Noah is 80cm taller than Alex.
Hope this helps! :)
Answer:

Step-by-step explanation:
Using Exterior angle theorem
30+130=160
Step-by-step explanation :
Answer:
a.
b. $37.50
Step-by-step explanation:
To find out how much the 5 were paying in total, we can add the bill and the tip. This gives us x + 10. Since there are 5 people and they are splitting the bill equally, the total amount would be divided by 5 to get the amount each person pays:
. We already know the amount they each paid, as it is given as $9.50. Both expressions represent the same thing, do we can set them equal to each other:

Now, we can solve.
First, we can multiply by 5 on both sides to get:
47.5 = x + 10
And then subtract 10:
x = 37.5
This means the bill before the tip was $37.50
Answer:
JH = 8, GH = 12, and GJ = 10.6
Step-by-step explanation:
According to Midsegment Theorem, a segment that connects the midpoints of two sides of a triangle is half the length of the third side.
GH = ½ DE
JH = ½ DF
GJ = ½ EF
DE is 24, so GH = 12.
JH is half of DF. Since G is the midpoint of DF, DG is also half of DF. So JH = DG = 8.
GJ is half of EF. Since H is the midpoint of EF, HE is also half of EF. So GJ = HE = 10.6.
