10. The sum of two numbers is 6 less than twice the first number. Their difference is 10 less than four times the second number.

Ilya [14]

Answer:

10 and 4.

Step-by-step explanation:

Let x be the first number.

Let y be the second number.

x + y = 2x - 6

x - y = 4y - 10

x = 4y - 10 + y

x = 5y - 10

(5y - 10) + y = 2(5y - 10) - 6

6y - 10 = 10y - 20 - 6

6y - 10 = 10y - 26

6y - 10y = -26 + 10

-4y = -16

y = 4

x - (4) = 4(4) - 10

x - 4 = 16 - 10

x - 4 = 6

x = 6 + 4

x = 10

Solve the system of equations 2y - 3x = -27 5y + 3x = 6 PLEASE EXPLAIN STEPS! (photo included)

Solnce55 [7]

Answer:

(7, -3)

Step-by-step explanation:

Add the two equations to eliminate x:

7y = -21

Then solve 7y = −21 for y:

$\frac{7y}{7}$ = $\frac{-21}{7}$ (Divide both sides by 7)

y = -3

Now that we've found y let's plug it back in to solve for x.

Write down an original equation:

2y - 3x = -27

Substitute -3 for y in 3y - 3x = -27:

(2)(-3) - 3x = -27

-3x - 6 = -27 (Simplify both sides of the equation)

-3x - 6x + 6x = -27 + 6 (Add 6 to both sides)

-3x = -21

$\frac{-3x}{-3}$ = $\frac{-21}{-3}$ (Divide both sides by -3)

x = 7

How can I graph 34+12d>100 on a number line?

marissa [1.9K]

Answer:

d> 5.5

The graph in the attached figure

Step-by-step explanation:

we have

$34+12d>100$

Solve the inequality for d

That means ---> isolate the variable d

Subtract 34 both sides

$12d>100-34\\12d> 66$

Divide by 12 both sides

$d>\frac{66}{12} \\d>5.5$

The solution is the interval (5.5,∞)

All real numbers greater than 5.5

In a number line the solution is the shaded area at right of d=5.5 (open circle)

The value of d=5.5 is not included in the solution

A 50-litre solution is 3 percent salt by volume.

yulyashka [42]

Answer:

Step-by-step explanation:

.03(50) + 0x = (50-x).05 How much 3% salt much be added to zero percent salt to create a mixture that is 5 percent salt.

3(50) = (50 - x)5 I multiplied through by 100 to clear the decimals

150 = 250 - 5x Distribute the 5

-100 = -5x Subtract 100 from both sides of the equation

20 = x divide both sides by -5
