Answer:
They are counting in even numbers, so using my counting skills, the answer is 4.
3s+28=85, take away 28 from both sides of the equals to give you 3s=57, divide by 3 on both side to give you s=19.
Answer:
Number is two
Step-by-step explanation:
First of all we find the closest factors of 864 which are 32 x 27
Simply them we have
32 x 27 = 2^5 x 3³
So
Next we know that to be aperfect cube, each exponent needs to be equally divided by divisible by 3.
So If we multiply 864 x 2 we get
Then
1728 = 2^6 x 3³
So if we finally
Take the cube root of that is 2²* 3^1 = 4 x 3= 12
So 2² x 3^1
So if we equate the powers we have the answer as 2.
Answer:
x=6/31, y=147/31. (6/31, 147/31).
Step-by-step explanation:
y=-22x+9
y=40x-3
-----------------
-22x+9=40x-3
9=40x-(-22x)-3
9=40x+22x-3
9=62x-3
62x=9+3
62x=12
x=12/62
simplify,
x=6/31
-----------------
y=40(6/31)-3=240/31-3=240/31-93/31=147/31
x=6/31, y=147/31.
