The answer is X=1.5.
3.5(2.5+x)=14
8.75+3.5x=14
8.75+3.5x=14
3.5x=5.25
X=1.5

Answer: so first you want to do 3.5 x the 2.5 and you get 8.75, then do 3.5 x X and you get 3.5x. now the equation is 8.75 +3.5x=14. take 8.75 nnd subtract it from itself and 14 then you are left with 3.5x=5.25. divide 5.25 by 3.5x and you get 1.5. so the answer is x=1.5

Solve the equation: 1/6d+2/3=1/4(d-2)
nlexa [21]

d/6+2/3=1/4(d-2)

d/6+2/3=d-2/4

2d+8=3(d-2)

2d+8=3d-6

8=3d-6-2d

8=d-6

8+6=d

14=d

d=14

HOW DO I FIND QR<br><br> PLEASE HELP
Paul [167]

Solution: For finding QR we need to apply Pythagoras Theorem

What is Pythagoras Theorem ?

ans : Pythagoras Theorem is the sum of square of two sides which is equal to the third side or the hypotenuse. This formula is valid oy incase of Right-Angled Traingle because one of three angles here is 90°

According to this law let's apply it in the diagram shown here.

  • (Hypotenuse)² = (Adjacent)² + (Opposite)²

  • (PR)² = (QR)² + (PQ)²

  • (5x - 2)² = (QR)² + (3x - 1)²

  • (QR)² = (5x - 2)² - (3x - 1)²

After factorising both of them we get

  • (QR)² = 25x² - 20x + 4 - (9x² - 6x + 1)

  • (QR)² = 25x² - 20x + 4 - 9x² + 6x - 1

  • (QR)² = 16x² - 14x + 3

  • QR = √(16x² - 14x + 3)

So, QR is √(16x² - 14x + 3)
