Answer:

The\ value\ of\ x\ is\ \frac{2}{5} .

Step-by-step explanation:

As the proportion given in the equation be

\frac{5}{2x} = \frac{25}{4}

Simplify the above

x = \frac{5\times 4}{2\times 25}

Solving the above

x = \frac{20}{50}

Thus

x = \frac{2}{5}

Therefore\ the\ value\ of\ x\ is\ \frac{2}{5} .

If you graph y=2x+1 and y=x+1 how many times would the two lines intersect
krok68 [10]
Given that they follow the format for straight lines and are therefore straight lines, they would only intersect once and that would be at (0,1) where they both have a y intersect.

Hope this helps :)

HELLP ME PLS QUICK
MAVERICK [17]

Answer:

Both Oscar and Kim will have enough to purchase the book.

Step-by-step explanation:

Oscar takes 30% of the normal price and subtracts it from the normal price. Out of 100% price he takes 30% so the result is: 100-30%= 70% of the normal price. Oscar's first step has the same result as Kim.

Oscar takes 10% of the discounted price (70%) and adds it back. The price will become 70% + 10%*70%= 77% of original price. Kim multiplies the discounted price with 110%, so the price will be: 70% * 110%= 77%. Both also give the same result.

The final price is 77% of the original, it will be: $28.50* 77%= $21.945

Oscar :

28.50 - 0.30(28.50) = 28.50 - 8.55 = 19.95

0.10(19.95) + 19.95 = 2 + 19.95 = 21.95

Kim :

0.7(28.50) = 19.95

1.10(19.95) = 21.95

Transform the equation to isolate x: ax = bx 1. How is the value of x related to the difference of a and b?
cestrela7 [59]

Answer:

The value of x is reciprocal of the difference of a and b.

Step-by-step explanation:

We are given the equation, ax=bx+1

On simplifying, we get,

ax=bx+1

i.e. ax-bx=1

i.e. (a-b)x=1

i.e. x=\frac{1}{a-b}

So, we get,

The value of x is \frac{1}{a-b}.

That is, the value of x is reciprocal of the difference of a and b.
