Answer:
Can not be determined
Step-by-step explanation:
regularly, you would +20 to both sides, but without a full =, you cant solve. If the equation is 6x-20=0, x would equal 3 2/6.
Hope this helps!
Answer:
7.2
Step-by-step explanation:
1. Natalie needed 40 minutes to get to school. In hours 40 minutes is 40/60= 2/3 hour (because there are 60 minutes in an hour). so her speed is 14.4/(2/3)= 14.4*3/2= 21.6 mph.
2. Britany needed 40+20= 60 min. 60 min= 1 hour. so she needed 1 hour her speed is 14,4/1= 14.4mph
3. The difference 21.6-14.4=7.2 is the answer .
Whats the question?......................
The answer is x(x+7)=169 because the formula for a right triangle is a^2+b^2=c^2. With that said 13 squared as the hypotenuse is 169. since ether is one side that has to be 7 feet longer than the other side that means you add 7 to the unknown length, x. Then you still have to add x into the equation considering it is still aprat of the problem. HOPE THIS HELPS!!!
