Two numbers have a sum of 7. When the smaller number is subtracted from twice the larger number, the result is 20. Which is the
Katyanochek1 [597]

Answer:

9

Step-by-step explanation:

according to the condition it is possible to make up a system of two equations (if to suppose 'l' - the larger number and the 's' - is the smaller one):

1. 'two numbers have a sum of 7' means s+l=7;

2. 'When the smaller number is subtracted from twice the larger number, the result is 20' means 2*l-s=20.

3. the system of two equations is:

\left \{ {{s+l=7} \atop {2l-s=20}} \right.  \ => \left \{ {{s=-2} \atop {l=9}} \right.

4. the larger number is 9.

Type an inequality statement using the < or > for the inequality symbols solve for x 6x-11-13x<7-5x
lozanna [386]

Answer:

-9 < x

Step-by-step explanation:

6x-11-13x<7-5x

Combine like terms

-11-7x<7-5x

Add 7x to each side

-11-7x+7x<7-5x+7x

-11 < 7+2x

Subtract 7 from each side

-11-7 < 7-7+2x

-18 < 2x

Divide by 2

-18/2 < 2x/2

-9 < x

Point s is between r and t on segment rt . use the given information to write on equation in terms of x. solve the equation. the
Juli2301 [7.4K]
RS + ST = RT
The equation is:
2 x + 10 + x - 4 = 21
3 x + 6 = 21
3 x = 21 - 6
3 x = 15
x = 15 : 3
x = 5
RS = 2 * 5 + 10 = 10 + 10 = 20
ST = 5 - 4 = 1
Answer: Segment RS = 20 and ST = 1

I am thinking of a number. If you multiply my number by 4, add -4 to the product, and then take 1/3 of the sum, the result is -6
Vlad [161]
The easiest way to solve this is to create an equation. Let's let the variable n represent the unknown number.

1/3(4n - 4) = -6

First, we should divide both sides by 1/3, to cancel it out on the left side of the equation.

4n - 4 = -18

Next, we should add 4 to both sides to cancel out the -4 on the left side.

4n = -14

Finally, we should divide both sides by 4, to get the variable n alone on the left side.

n = -3.5

Therefore, the number is -3.5.

You know that this is the answer because if you plug it back into the orginal equation it works.
