Advocard [28]

Answer:

Step-by-step explanation:

i assume x+y=6(1/2)=\frac{13}{2}

$\frac{5}{8}=\frac{x}{y}=\frac{x}{\frac{13}{2}-x}=\frac{2x}{13-2x}\\65-10x=16x \\26 x=65\\2x=5\\x=\frac{5}{2}\\y=\frac{13}{2}-\frac{5}{2}=\frac{8}{2}=4$

25 percent is the same as the decimal 0.25.

Multiply 100 by 0.25 to see what 25% of 100 is.
100x0.25=25

Then, to find the price raised by 25%, add 25 to 100.
100+25=125

The final answer is $125.

Hope this helps!

The solution for the following system of equations is shown on the graph. What is the solution?

Bingel [31]

The solution is (3 , 4) ⇒ 2nd answer

Step-by-step explanation:

The system of equations can be solved by:

Elimination method
Substitution method

The system of equations is:

y = 3 x - 5 ⇒ (1)

y = $\frac{1}{3}$ x + 3 ⇒ (2)

By using the substitution method substitute y in equation (2) by equation (1)

3 x - 5 = $\frac{1}{3}$ x + 3

Subtract $\frac{1}{3}$ x from both sides

$\frac{8}{3}$ x = 8

Divide both sides by $\frac{8}{3}$

x = 3

substitute x by 3 in equation (1)

y = 3(3) - 5

y = 9 - 5

y = 4

The solution is (3 , 4)

Probability help!!!!!

nirvana33 [79]

Let A be the event $A=\{choosing \;an \;odd \;number\}$ and B be the vent $B=\{choosing \;an \;even \;number\}$ . Since the intersection of the events $A\cap B=\phi$ , the events A and B are mutually exclusive.

The number is either odd or even. Since $P(A)+P(B)=1$ , the events are mutually exclusive and exhaustive.

Correct choice is "the number is either odd or even".
