X = (y/2) - 1 Please help me find the answer.

Mathematics
1 answer:
Juliette [100K]3 years ago
4 0

Answer:

Step-by-step explanation:

Well you didn't give directions on what to solve for,

I'm gonna assume you want to solve for y

x = (y/2) - 1 (add 1 to both sides)

x + 1 = y/2 (multiply both sides by 2)

2(x + 1) = y (distribute the 2)

y = 2x + 2

three brothers shared some oranges in the ratio of 6:4:2,if the brother with the largest share had 150 oranges, find the number
Alexus [3.1K]

Answer:

Step-by-step explanation:

The number of oranges with brothers be 6x, 4x , 2x

The brother with the largest share had 150 oranges. So,

6x = 150

x = 150/6

x = 25

4x = 4 * 25 = 100

2x = 2 *25 = 50

the number of oranges shared​ = 150+100 + 50 = 300 oranges

Question 9
timurjin [86]

Answer:

<u>The</u><u> </u><u>requ</u><u>ired</u><u> </u><u>num</u><u>ber</u><u> is</u><u> </u><u>7</u><u>0</u><u>.</u>

Step-by-step explanation:

let the no. be 10y + x where x is unit digit and y is ten's digit.

given , sum of the digit is 7

x + y = 7 ...(1)

also , reversing the no. we get 10x + y ,where x is ten's digit and y is unit digit.

given reversed digit decreases the number by 63 .

so, 10y + x - ( 10x + y ) = 63

9y -9x = 63

( dividing both side by 9 )

y - x = 7 ....(2)

adding 1 and 2 [ refer attachment ]

so the required original number is

10y + x = 10×7+0 = 70

(2xy) to the power of 3
Ymorist [56]

Answer:

8x³y³

Step-by-step explanation:

When the number is in parentheses, it means the exponent goes to all of the variables and numbers inside. So 2 squared is 8 and x squared and y squared are just written like that. I hope this helps clear things up...

Line MN passes through points M4, 3) and M7, 12). If the equation of the line is written in slope-intercept form, y-mx+ b, what
Butoxors [25]

Answer:

<h2>b = -9</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points M(4, 3) and N(7, 12). Substitute:

m=\dfrac{12-3}{7-4}=\dfrac{9}{3}=3

Therefore we have the equation:

y=3x+b

Put the coordinates of the point M to the equation:

3=3(4)+b

3=12+b            <em>subtract 12 from both sides</em>

-9=b

Solve for n: 21k – 3n + 9p &gt; 3p + 12.
Katyanochek1 [597]
21k - 3n + 9p > 3p + 12....for n
-3n > 3p + 12 - 9p - 21k
n < (3p + 12 - 9p - 21k) / -3
n < -p - 4 + 3p + 7k
n < 2p - 4 + 7k <===
