Solve simultaneously:
<span>15x-8y=52 and
6x+14y=38
</span>
Let's solve this system thru elimination by addition/subtraction:
Let's get rid of the x terms.
To do this, mult. the first eqn. by -6 and the second by 15. (This is not the only way in which we can do this!!) We get
-90x + 48y = -312
90x +210y = 570
--------------------------
Add all 3 columns together. We end up with:
258y = 258, so y = 1. You can find x by subst. 1 for y in either of the given equations.

Answer: 
Step-by-step explanation:
Given expression, 
= √(4×8)×√(4×7)×√3×√(3×√2)
= √4×√8×√4×√7×√3×√3×√2 ( because √(m×n)=√m×√n)
=√4×√4×√8×√2×√7×√3×√3
=4×√(4×2)×√2×√7×3
=4×√4×√2×√2×√7×3
=4×2×2×√7×3
=48√7
Thus,
=
Answer:
5500
Step-by-step explanation:
5000 + (10 / 100) x 5000 = 5000 + (1/10) x 5000 = 5000 +500= 5500 people visted the book fair in the second week
