2x-1=3/4x+9<br> Help Me Brainilist to whoever explains the best
alexdok [17]

Answer:

x=8

Step-by-step explanation:

normally it would be 2x-1=\frac{3}{4}x+9 so now we have to combine the x into one fraction which will be 2x-1=\frac{3x}{4}+9 now for my way i will be taking the -1 to the other side and when that happens its going to become positive so now the answer will be 2x=\frac{3x}{4}+10 ok so now we have to have the x's to the same side so i have to drag the fraction to the other side and making it positive which will conclude into 1.25x=10 and now 10 divided by 1.25 is 8 so the answer is x=8 (sorry for the ok nows) hope this helped

The area of a square garden is 50 m3. How long is the diagonal?
katen-ka-za [31]

Answer:

10 m

Step-by-step explanation:

If the area of a square is 50 m2, then the length of each side will be \sqrt{50} m, to get the diagonal length, after dividing the square by joining the points of the diagonal with a line, it forms two right angles with length \sqrt{50} m each.

the diagonal length represent the hypotenuse side of each of the right angle, knowing the pythagoras theorem:

(hyp)^{2} = (opp)^{2}   + (Adj)^{2}, so we have:

(diagonal)^{2}  = 50 + 50

(diagonal)^{2}  = 100

diagonal = 10 m
