Answer:
Step-by-step explanation:
because both equations do not have matching numbers for the x or y variable, and both equations are positive you are going to have to multiply each equation by a number so that there will be at least one variable with the same number but with opposite signs.
it does not matter which variable you choose.
lets use y because 2 and 3 are smaller then 2 and 5.
so lets multiply the first equation by 2 in order to get y equal to 6.
2(2x)+2(3y)=(2)6
(do not forget to multiply what the equation is equal to also)
4x+6y=12
now for the second equation we need y to equal negative 6
-3(5x)+-3(2y)=-3(4)
-15x-6y=-12
now lets put the 2 new equations next to each other and see what we can cancel out
4x+6y=12
-15x-6y=-12
-11x=0
x=0
now plug 0 in for x and solve for y (it does not matter which of the 4 equations you choose to solve.
2(0)+3y=6
3y=6
y=2
so your answer is x=0, y=2
Answer:
10.
Step-by-step explanation:
median means the "middle" number in a set of numbers.
(I always the meaning of median by remembering "middle" because they rhyme).
NOTE: to find the median of a set of numbers you have to arrange that set of numbers in either ascending order (smallest to biggest value) or descending order (biggest to smallest value) .
sooo....
we were given :
11, 17, 7, 4, 15, 19
let's arrange in ascending order
4, 7, 11, 15, 17 , 19
now you can cancel them out ( cancel left number, right number)
i mean....
cancel out 4, cancel out 19
cancel out 7, cancel out 17
and we are left with 2 numbers which <u>are11 </u><u>and </u><u>1</u><u>5</u><u>.</u>
<u>NOTE</u><u>;</u><u> </u><u>(</u><u>when </u><u>you </u><u>have </u><u>two </u><u>numbers </u><u>or </u><u>values </u><u> </u><u>remaining </u><u>instead</u><u> </u><u>of</u><u> </u><u>one </u><u>number,</u><u> </u><u>add </u><u>those </u><u>t</u><u>wo </u><u>numbers </u><u>and </u><u>divide</u><u> </u><u>by </u><u>2</u><u>)</u><u>.</u>
soooo...
11 + 15 = 20
20/2 = 10
median of the set of numbers is equal to 10.
Hope this helps.
Good luck ✅.

Answer:
6
Step-by-step explanation:
6+(6+2)+(6×3)=32
32÷(1+1+3)=6•••••2
So it's 6 and 6+2 and 6 times 3
which is 5 of number 6 plus 2
=6+(6+2)+(6×3)
=6+8+18
=32
