The sum of two numbers is 66. Two times the smaller number is 15 more than the larger number. What are the numbers? First one wi

Viktor [21]

Answer:

Larger number (y) is 39

Smaller number (x) = 66 - 39 = 27.

Step-by-step explanation:

Let the smaller number be<em> x</em> and the larger number be <em>y</em>.

Sum of two numbers = 66

According to question,

<em>x </em>+<em> y</em> = 66

<em>x</em> = 66 - <em>y</em>.........(1)

Now, since twice of smaller number is 15 more than the larger number, According to question,

2(smaller number) = larger number + 15

2<em>x</em> = <em>y</em> + 15 .........(2)

Now substituting the value of y from (1) in (2)

2 (66 - <em>y</em>) = <em>y</em> + 15

132 - 2<em>y</em> =<em> y </em>+ 15

-2<em>y - y</em> = -132 + 15

3<em>y </em>= 117

<em>y</em> = 117/3 = 39

So the largest number (y) is 39

Smaller number (x) = 66 - 39 = 27.

which of the following equations does the graph show below pls help l give u the branliest answer or wtvr

lesya [120]

Answer:

x - 5y = 5

Step-by-step explanation:

Let's represent the equation of the graph in slope-intercept form, y = mx + b.

We'd need to find slope (m) and y-intercept (b) of the graph.

Slope (m) = ∆y/∆x

Using two points on the line, (0, -1) and (5, 0),

Slope (m) = (0 - (-1)) / (5 - 0) = 1/5

m = ⅕

y-intercept (b) is the point on the y-axis where the line intercepts the y-axis = -1

Therefore, b = -1

To write the equation, substitute m = ⅕ and b = -1 into y = mx + b

Thus:

y = ⅕(x) + (-1)

y = ⅕(x) - 1

Rewrite in standard form:

-⅕x + y = -1

Multiply both sides by -5

-⅕x*-5 + y*-5 = -1*-5

x - 5y = 5

melamori03 [73]

To calculate expected value,
We can add up the probability of all possible events.
The 2 possible events are either winning $50 or losing the prize, which is $ - 50
Expected value =
50 x 40 % + (-50) x 60%
= $-10
So the answer is $-10
