Answer:
6( 5 + 2x )
Explanation:
30 = 2 x 3 x 5
12x = 2 x 2 x 3 x X
THE COMMON FACTOR IS 2 & 3
SO this is the answer
Hope this helps :)
I think it is 72.2 percent because 9x5=45k and 45k-32.5k= 12.5k so 32.5 percent of 45 is 72.2 (rounded to the nearest tenth) btw I feel lonely
I’m not sure how to explain why this is the answer because it’s mostly math explanation, but the probability of having 75 in the interval (50,100) will be 1/50
8x+16y = 39 and 40x+8y = 42 are the system of equations that represents in inches the relationship between the length of a blue tile and the length of a white tile.
<u>Step-by-step explanation</u>:
Let 'x' be the inches of a blue tile.
Let 'y' be the inches of a white tile.
8x+16y = 39 -------(1)
40x+8y = 42 -------(2)
Multiply eqn(2) by 2 and subtract it from eqn(1)
8x+16y = 39
(-) <u>80x+16y = 84</u>
<u>-72x = -45 </u>
⇒ x = -45/-72
⇒ x = 5/8
∴ Blue tile is 5/8 inches.
substitute x=5/8 in eqn(1)
⇒ 8(5/8) + 16y = 39
⇒ 16y = 39-5
⇒ y =34/16
⇒ y = 17/8
∴ White tile is 17/8 inches.
