Answers

Answer 1

Answer: Given:
Each morning: 1.2 hours of reading
Each evening: 2.5 hours of reading
Total number of hours spend reading in 8 days.

B. Step 1: Multiply 1.2 by 8. Step 2: Multiply 2.5 by 8. Step 3: Add the two products

1.2 hours * 8 days = 9.6 hours
2.5 hours * 8 days = 20 hours
total 29.6 hours

Solve 7x – 2y = –3
14x + y = 14 a. (4,5/7) b. (4,7/5)
c. (5/7,4) d. (7/5,4)

Answers

The value of x " $(5)/(7)$ " and the value of y is "4".

Linear equation:

Given equation are:

$7x-2y=-3\n\n14x+y=14$

x,y=?

Let

$7x-2y=-3..........................(a)\n\n14x+y=14.........................(b)\n$

solve equation (a)

$\to 7x-2y=-3\n\n\to 7x=-3+2y\n\n\to x=(-3+2y)/(7)................(d)\n$

putting the value of x into equation (b):

$\to 14((-3+2y)/(7)) +y=14\n\n\to 2(-3+2y) +y=14\n\n\to -6+4y +y=14\n\n\to 5y=20\n\n\to y=(20)/(5)\n\n \to y=4$

Putting the value of y into the equation (d):

$\to x=(-3 +2(4))/(7)\n\n\to x=(-3 +8)/(7)\n\n\to x=(5)/(7)\n\n$

Therefore the final value of x is " $(5)/(7)$ " and y is "4".

Multiply the 1st equation by 2 to get:
2x-4y=2
Subtract this result from the 1st equation to get:
3y=18
y=6
Substitute that into the 1st equation to get:
x-2*6=1
x=13
-------
Solution: x=13; y=6

Answer:

13 and 6

Step-by-step explanation:

Let x = larger number

Let y = smaller number

The larger of two numbers is: x =

one more than twice the smaller: 2y + 1

x = 2y + 1 {equation 1}

The sum of the numbers is: x + y =

20 less than three times the larger: 3x - 20

x + y = 3x - 20

This can be simplified. Subtract 3x from both sides.

x - 3x + y = -20

-2x + y = -20 {equation 2}

Since we already know from equation 1 that x=2y+1, substitute that into equation 2

and solve for y:

-2(2y+1) + y = -20

-4y - 2 + y = -20

-3y - 2 = -20

-3y = -18

y = -18/(-3)

y = 6

x = 2y+1 = 2(6)+1 = 12 + 1 = 13

Your numbers are 13 and 6
