Answer:
the first one
Step-by-step explanation:
angle L congruent to angle P
12x/15-10x/15
=2x/15 is your answer
Answer:
Step-by-step explanation:
Basically you can see it hits -5 as a minimum and that means there is 2 there and then -1 and then hits 4 3 times and then 7
So your answer is x=-5 with multiplicity of 2 x=-1 and x=4 with multiplicity of 3 and x=7 once.
Answer:
20
Step-by-step explanation:
If 36 boys can conplete a task in 4 hours, then 19.35 boys could do it in 2 and a fourth hours.
You can set up an equation
A fourth of an hour is 15 minutes, so,
36 is to 4 as x is to 2.15, or,
36=4 as X=2.15
Multiply 2.15 by 36 (77.4)
77.4 divided by 4= 19.35.
Of course, you cannot have 19.35 boys, so there must be 20.
Hope this helps!
