12^2 +b^2 = 20^2 because of the Pythagorean theorem
144 + b^2 =400
B^2 =256
B=16
Answer:
A.) Eric rode 2 more miles per week than Kim rode
Step-by-step explanation:
A.) Eric rode 2 more miles per week than Kim rode
B.)Kim rode 3 more miles per week than Erick rode
C.) Kim rode 11 more miles per week than Erick rode
D.) Eric rode 17 more miles per week than Kim rode
Kim rode her biyciclye 135 miles in 9 weeks.
Number of miles Kim rode per week = Total miles travelled / number of weeks
= 135 miles / 9 weeks
= 15 miles per week
Eric rode her biciclye 102 miles in 6 weeks
Number of miles Eric rode per week = Total miles travelled / number of weeks
= 102 miles / 6 weeks
= 17 miles per week
The correct answer is
A.) Eric rode 2 more miles per week than Kim rode

28/5= 5 3/5 15/7= 2 1/7 21/4=5 1/4
Step-by-step explanation:
The distributive property states that:
a(b+c)=ab+bc.
or more generally: a(b+c+d)=ab+av+ad.
This is a very useful tool to perform multiplication.
For example, if we want to multiply 7 by 234, we can proceed as follows:
7*234=7(200+30+4)=7*200+7*30+7*4=1400+210+28=1610+28=1638
back to our problem,
4 * 24 = 4(20+4)=4*20+4*4=80+16=96 ($)
So, instead of multiplying 4 by 24, we multiplied 4 by 20 and 4, which is easier, and then added these together.
Answer:
4 * 24 = 4(20+4) [=4*20+4*4=80+16=96 ($)]
