Given :
There are 50 people at the city swim park today. Everyone in the park was wearing swim suits or sunglasses, some people had both.
38 have swim suits on and 25 have sunglasses.
To Find :
How many people had swim suits on but not sunglasses.
Solution :
Let, A refer swim suits and B refer sunglasses.
∞∪∩
A ∪ B = 50
A = 38
B = 25
We need to find, A - (A ∩ B) .
We know,
(A ∩ B) = A + B - (A ∪ B)
(A ∩ B) = 38 + 25 - 50
(A ∩ B) = 13
So, A - (A ∩ B) = 38 - 13 = 25
Therefore, number of people with swim suits on but not sunglasses are 25.
Answer:
y = 1/3x - 1
Step-by-step explanation:
Given the slope of 1/3, and the point (-3, -2): we can plug these values into the slope-intercept form, y = mx + b where:
m = slope
b = y-coordinate of the y-intercept, (0, <em>b</em>)
y = mx + b
-2 = 1/3(-3) + b
-2 = -1 + b
Add 1 to both sides to solve for b:
-2 + 1 = -1 + 1 + b
-1 = b
The y-intercept is b = -1.
Therefore, given the slope, m = 1/3, and y-intercept, b = -1:
the linear equation in slope-intercept form is:
y = 1/3x - 1

Xp + yp = z....for p
p(x + y) = z
p = z / (x + y)
a = b + cp.....for p
a - b = cp
(a - b) / c = p
Answer:
x=5
Step-by-step explanation:
Move the variable to the left-hand side and change its sign. Move constant to the right-hand side and change its sign.
-8.75x+5.25x = -3.5-14
Collect like terms
-3.5x = -17.5
Divide both sides of the equation by -3.5
x=5
