Answer:
20
Step-by-step explanation:
Let's start by rewriting the second equation in terms of "x":
Subtract y from both sides:
Now, substitute "5-y" for "x" in the first equation:
Note that:
Cancel out like terms:
Subtract 25 from both sides:
Divide both sides by -10
Now, substitute this value back into either of the equations to solve for x.
Add 15/2 to both sides:
Now, find the difference:
10/2.5= 4 the answer is 4 meters because you just divide them.
anaalyze the problem
first term: -1
common difference: +9 (8-(-1) is 9)
so, an=-1+9n-9
answer is an=9n-10, with n bigger or equal to one
sixth term,plug in 9(6)-10=54-10=44
tenth term, plug in 9(10)-10=90-10=80
Answer:
-65/24
Step-by-step explanation:
-26/8 * 5/6 .To divide by a fraction, multiply bhy the reciprocal of that fraction. -13/4 * 5/6. Reduce the fraction with two. multiply -13/4*5/6 and you get -65/24
We know that
applying the Pythagoras theorem
LM²=LV²+VM²
LM is the radius of the circle
LV=5 in
VM=12/2----> 6 in
so
LM²=5²+6²-----> LM²=61------> LM=7.81 in------> LM=7.8 in
the answer is
7.8 in
