Here are the equations
x+y=48
x/y=5/8


but here's how I would solve it

5+7=12
48=12units
divide by 12 both sides
4=1unit

males=5 unit
4=1unit
times 5
20=5unit=males

females=7unit
4=1unit
times 7
28=7unit=females

Answer: x+y=48

\dfrac{x}{y}=\dfrac{5}{7}\Rightarrow\ 7x=5y

Step-by-step explanation:

Let x represent the number of males on the ride. Let y represent the number of females on the ride.

As per given , we have ,

x+y=48---(i)

\dfrac{x}{y}=\dfrac{5}{7}\Rightarrow\ 7x=5y---(ii)

From (i) and (ii), the required  two linear equations form a system that you can use to find the number of males and the number of females on the ride are :

x+y=48

\dfrac{x}{y}=\dfrac{5}{7}\Rightarrow\ 7x=5y

How can you decompose the composite??​
zhannawk [14.2K]

Answer:

  as a semicircle, a hexagon, and a rectangle

Step-by-step explanation:

The first attachment shows the decomposition according to the answer choice above. It would make area computation about as simple as it could be.

__

The second attachment shows a decomposition with a circle. It leaves a very odd shape in the middle that is not easily divided into triangles, rectangles, or trapezoids.

The third attachment shows a semicircle, a pentagon, and two triangles. The pentagon is <em>not a regular pentagon</em>, so might require further decomposition in order to determine its area.

If p∨q is true, then what must be true about the truth values of p and q?
kiruha [24]
Switching the hypothesis and conclusion of a conditional statement and negating both. For example, the contrapositive of "If it is raining then the grass is wet" is "If the grass is not wet then it is not raining." Note: As in the example, the contrapositive<span> of any true proposition is also true.

Therefore, the answer would be:

</span><span>If I don't spend money, then I don't have it.</span>

All the fraction that are greater than 1\2
never [62]
Hi There!

Change all the fractions to decimal you do that by dividing numerator by the denominator. Remember \frac{1}{2}   as a decimal is 0.5

A=  \frac{3}{7}  =    0.43

B=  \frac{5}{9}  =    0.60

C=  \frac{8}{10} =   0.8

D=   \frac{5}{12} =   0.42

E=    \frac{3}{5}   =   0.6

Based, on the data above B,C,E are greater than \frac{1}{2} because they all have decimals greater than 0.5, B= 0.6, C= 0.8, E=0.6

So, \frac{5}{9} ,\frac{8}{10} ,\frac{3}{5}  are all greater than \frac{1}{2}

Hope This Helps :)
