Answer: a = 1.75
Explanation :
4a + 7
Using transposition method we move 4 and change its sign
a = 7 / 4
7 / 4 = 1.75
Therefore,
a = 1.75
Let the breadth be x
length=x+8
according to the question
area of the pool = l*b
105=x*x+8
if u solve this equation further u will get the answer
Answer:
∠K =24
∠L =66
Step-by-step explanation:
first you need to find X in order to solve.
since they are Complementary they add together to equal 90 degrees
so we can set them equal to 90
13x-1=90
13x=91
x=7
now we can plug them in!
---
∠K = 3(7)+3 = 24
∠L =10(7)-4=66
1) -3(5x+2y=-3)⇒ -15x-6y=9
⇒ -9x=27
2(3x+3y=9)⇒ 6x+6y=18
2) -9x/-9=27/-9 ⇒ x=-3
3) 3(-3)+3y=9⇒ -9+9+3y=9+9⇒ 3y/3=18/3⇒ y=6
Answer: (-3,6)
Reasoning:
Step 1) In order to eliminate, first I had to multiple the first equation by -3 and the second by 2 so that when combining the equations y would cancel each other out so that I could solve for x. <em>Note: There are many combinations as to how you could multiple the equations so that either the x or y would cancel out.
</em>
Step 2) Once y is eliminated, solve for x.
Step 3) Now plug x back into one of the original equations and solve for y. <em>Note: Plug x back into one of the original equations, not the equations that were changed by multiplication,</em>
