Answer:
B. 50
Step-by-step explanation:
AD=AB so 13=AD also.
DE=12 so EB=12 also.
When you add DE and EB together you get DB= 24
There are 2 legs and 1 hypotenuse to a triangle. Your legs are a+b and you hypotenuse is c.
AD=a(13) AB=b(13) DB=c(24)
P= a+b+c
so you add 13 + 13+ 24
If y=12 and x=6 and we substitute this numbers to the equation. 12=6+6 is true and 2 (6)=12 is also true so B is the answer.
If you would like to know Johnathan's average speed in miles per hour, you can calculate this using the following steps:
3 2/3 = 11/3 miles ... 7/8 hour
x miles = ? ... 1 hour
11/3 * 1 = 7/8 * x
11/3 = 7/8 * x
x = 11/3 * 8/7
x = 88/21
x = 4 4/21 miles
The correct result would be 4 4/21 miles per hour.
Answer:
90
Step-by-step explanation:
9 x (3)2 + 9 first do the parenthesis
9 x 9 + 9 I am assuming the 2 was an exponent
81+9
