The answer is 27 tiles !
21 white tiles × 3 = the total area it takes up!
21 × 3 = 63
144 - 63 = 81
81 is the area left!
Divide by 3 to find how many black tiles are needed!
81÷ 3 = 27
Hope I Helped !
Answer:
48
Step-by-step explanation:
21 white tiles = 63 cm2
total number is 144
144-63 = 81
81/3 = 27
so 27 black tiles
21+27 = 48 total.

x/2 + 10 = 35 - 2x
x/2 + 2x = 35 - 10
5x/2 = 25
5x = 25.2
5x = 50
x = 50/5
x = 10
The number is 10

For the first one:
The radian of 60º is 1.047. you just have to find one that has the same value, which would be 
/3. (the last choice).
for the second one:
you do it the other way. The answer is 45 degrees.
Answer:
y = 2/3x+1/3
Step-by-step explanation:
2x−3y+1 = 0
Solve for y
Add 3y to each side
2x−3y+1 +3y= 0+3y
2x +1 = 3y
Divide by 3
2/3 x + 1/3 =3y/3
2/3x +1/3 = y
The slope is 2/3 and the y intercept is 1/3
y = 2/3x+1/3
