If AB = CD, then 3x+4 is equal to 4x-1

3x + 4 = 4x - 1
Add one to both sides to cancel out.
3x + 5 = 4x
Subtract 3x from both sides to cancel out.
5 = x

Now, substitute the 5 in place of the x in the equation for AB (3x+4)

3(5) + 4
15 + 4
19

Final Answer: B) 19

Evaluate. -|-7 + 3| <br> 4<br> -4<br> -10

agasfer [191]

Your answer is 4

You have to use the distribute property and distribute the - to the -7 and the 3

The -7 will become and the 3 will become -3

Then you add those together and when you add a negative to a positive you basically subtract

So 7+-3 is 4

A is your answer

The ratio of the number of cups of blue paint to the number of cups of red paint that Lara mixed to make a shade of purple paint

Vikki [24]

Answer:

Generally given that the number of cups of blue to that of red paint is 3: 1 then the Lara mixed 3 cups of blue paint with 1 cup of red paint

The number is $x= \frac{1}{3}$

The price is $P = \$ 8$

Step-by-step explanation:

From the question we are told that

The ratio of the number of cups of blue paint to the number of cups of red paint is $r = 3: 1$

Generally given that the number of cups of blue to that of red paint is 3: 1 then the Lara mixed 3 cups of blue paint with 1 cup of red paint

Given that 1 cup of red paint => 3 cups of blue paint

x cup of red paint => 1 cup of blue paint

$x= \frac{1 * 1}{3}$

=> $x= \frac{1}{3}$

Generally the unit price of a cup of blue paint is mathematically represented as

$P = \frac{48}{6}$

=> $P = \$ 8$
