Answer:-4(2x - 1) > 5 - 3x

solution:

-4(2x) -4(-1) > 5 - 3x Distribute -4 to get -8x + 4 > 5 - 3x

-8x + 4 > 5 - 3x

+3x + 3x

-5x + 4 > 5

- 4 -4

-5x > 1

÷ -5 ÷ -5

x < - 1/5

Answer:

Step-by-step explanation:

-4(2x - 1) > 5 - 3x

The first step would be to expand the brackets.

-4( 2x ) - 4( -1 ) > 5 - 3x

Distribute the -4 to 2x and -1 to get:

-8x + 4 > 5 - 3x

Tickets for a play cost $3 for children and $10 for adults. A group of 25 people paid a total of $201 for tickets to the play. H

lidiya [134]

Answer: There were 7 children

Step-by-step explanation:

Let's use x to represent the children and y to represent the adults.

We know they combine to make a group of 25 people so x+y=25

We also know that they paid $201 and that there is $3 per child and $10 for adults so 3x+10y=201

I will solve by substitution.

Solve for y in the first equation

$x+y=25\\x-x+y=25-x\\y=25-x$

Sub in our value for y into the other equation and solve for x

$3x+10y=201\\3x+10(25-x)=201$

Step 1) Simplify

$3x+250-10x=201\\-7x+250=201$

Step 2) Subtract 250 from both sides

$-7x+250-250=201-250\\-7x=-49$

Step 3) Divide both sides by -7

$\frac{-7x}{-7} =\frac{-49}{-7}\\x=7$

$\frac{231}{4}$ ✅

Step-by-step explanation:

$\frac{33}{4} \times \frac{21}{3} \\ = \frac{11 \times 21}{4} \\ = \frac{231}{4}$

Note:-

A fraction is said to be written in its lowest form if its numerator and denominator are prime, that is, they have no common factors other than 1.

$\frac{2 |x - 3| }{5} = 6 \\$

$5 \times \frac{2 |x - 3| }{5} = 5 \times 6 \\$

$2 |x - 3| = 30$

$\frac{2 |x - 3| }{2} = \frac{30}{2} \\$

$|x - 3| = 15$

$x - 3 = 15$

$x - 3 + 3 = 15 + 3$

$x = 18$

$x - 3 = - 15$

$x - 3 + 3 = - 15 + 3$

$x = - 12$
