Answer:-1/6
Step-by-step explanation:
-1/2 + (3/4times4/9)
-1/2 + (3/4 x 4/9)
-1/2 + (3x4)/(4x9)
-1/2 + 12/36
(18 x -1 + 1 x 12)/36
(-18+12)/36
-6/36=-1/6
Answer:
r = 0.1
Step-by-step explanation:
If (x, y) = (14, 1.4) and the quantities are proportional, the constant of proportionality (r) in ...
y = rx
is ...
r = y/x = 1.4/14 = 0.1
The constant of proportionality is 0.1.
Answer:
75 green tiles
Step-by-step explanation:
Green : Blue = 3 : 4
3 : 4 = x : 100
Write as fractions
3/4 = x/100
Cross Multiply (numerator * denominator / numerator * denominator)
300 = 4x
Divide both sides of the equation by 4
x = 75

-4 x 6 = -24
-24 x 6 = -144
-144 / 6 = -24
-24 - 47 = -71
