hjlf

Answer:

Step-by-step explanation:

<h2><u>☼︎</u><u>Answer:</u></h2>

The cost price of cow = Rs.80

Explanation:

<h2><u>☼︎</u><u>Given :-</u></h2>

By selling a cow for Rs 144, there is a profit of the same percentage as its cost price.

The cost price.

The cost price of cow = Rs.x

<h2><u>☼︎</u><u>Solution :-</u></h2>

$\sf x + x \: of \: x\%= 144 \\ \\ \sf \implies x + \frac{x \times x}{100} = 144 \\ \\ \sf \implies {x}^{2} + 100x - 14400 = 0 \\ \\ \sf \implies x(x - 80) + 180(x - 80) = 0 \\ \\ \sf \implies x + 180 = 0 \\ \\ \sf \implies x = - 180 \\ \\ \sf \therefore \: {\boxed{ \sf \pink{x = 80}}}$

<h2><u>Hence: </u></h2>

The cost price of cow =<u>R</u><u>s</u><u>8</u><u>0</u>

A line with a slope of 1 passes through the points (5,w) and (-7,-9). what is the value of w?

sladkih [1.3K]

Slope = difference in y / difference in x
Slope = (w --9) / (5 --7)
Slope = (w +9) / (5 + 7)
12 * slope = w +9
w = 12*slope -9 and since slope = 1,
w = 12 -9
w = 3

Andy and Bob took a test that had 120 problems. Andy got 30 more problems correct than Bob. The number of problems that only And

Vadim26 [7]

Both boys get 14 problems <em>correct </em>of the <em>entire</em> test composed by 120 problems.

<h3>Procedure - Determination of the number of problems that Andy and Bob got correct in a test</h3>

In this question we must determine how many questions Andy and Bob got correct. The total of problems ( $p$ ) is the sum of problems that neither got correct ( $x$ ), problems that only Andy got correct ( $y$ ) and problems that both boys got correct ( $z$ ). Hence, we have the following algebraic expression:

$p = x + y + z$ (1)

And according to the statement, the relationships between the number of problems got correct by Andy and the number of problems that Bob got correct ( $u$ ) is described by the following expressions:
