Answer:
I'm newbie here
Step-by-step explanation:
Elimination Method.
4x + 6/y = 15 → step 1
6x - 8/y = 14 → step 2
so,
4x + 6/y = 15 |×6|
6x - 8/y = 14 |×4|
24x + 6/y(6) = 90
24x - 8/y(4) = 56
24x + 36/y = 90
24x - 32/y = 56
____________ _
68/y = 34
68 = 34y
34y = 68
y = 2
subsitution y = 2 to..
4x + 6/y = 15
4x + 6/2 = 15
4x + 3 = 15
4x = 12
x = 3
So, for x is 3, and for y is 2
Answer:
$54
Step-by-step explanation:
Since its $0.24 per 1 square inch, you would multiply 0.24 by the total amount of square inches. When we do this, we get 54 as our answer.\
Hope this helps!
Answer:
= a
Step-by-step explanation:
We have to evaluate the expression, 'Radical a squared'.
Now, radical means square root.
So, our expression becomes, 'Square root of 'a' square'.
That is, the expression is .
We know that, the square root of some squared value is the value itself.
So, = a
Hence, the real number for 'radical a squared' i.e. is 'a'.
