Answer:
Let's just call the number x. 3/8ths of x and 1 more equals 11.
As an equation, this basically means
If a line is drawn across the shape connecting two of the angles it makes two triangles. The sum of the angles in a triangle is 180 degrees.
Since this shape makes two triangles the sum of the inside angles is 2 * 180 = 360 degrees
(2x - 17) + 90 + x + 59 = 360
combine like terms
3x + 132 = 360
3x = 360 - 132
3x = 228
x = 76
The r% of a quantity x is computed by dividing x in 100 parts, and considering r of such parts. So, the r% of the male is
and similarly, the r% of female is
The number of males decreased by this quantity, so now it is
and the number of female increased by this quantity, so now it is
we know that these two new counts are the same number, so we can build and solve the equality
Subtract 20 and add 0.3r from both sides:
Divide both sides by 0.5 to solve for r:
Let's check the answer
The 20% of 30 is , while the 20% of 20 is 4. So, we are stating that which is true because both expressions evaluate to 24.
C. -5y -4 = -(x+3)^2 -1/2
Hope I am right.
Answer:
Wendy must mix .25 with .75
Step-by-step explanation:
Because 1 is a third of 3 which makes the process for the decimals.
