Answer:

x = 27

Step-by-step explanation:

Given

3x - 4y = 65 ← substitute y = 4 into the equation

3x - 4(4) = 65

3x - 16 = 65 (add 16 to both sides )

3x = 81 ( divide both sides by 3 )

x = 27

Saul makes green paint by mixing blue paint and yellow paint.
Mamont248 [21]

Answer:

12 gallons of yellow paint

4 gallons of blue paint

Step-by-step explanation:

saul’s paint ratio is 3b to 1y which makes 4ounces of paint total (3b+1y=4)

So if you want 16 gallons of paint total using the same ratio of colors then you need to figure out how many of the recipe you will need to put in by dividing

16/4=4 so 4 times the original recipe

Now multiply the original paint numbers by 4 since you will do the ratio 4 times

3y*4= 12 gallons of yellow paint and

1b*4= 4 gallons of blue paint


Hope this helps! :)

Please solve, thank you (and show steps):<br><br>Solve for x:<br><br>5x + 22 = 27​
IrinaVladis [17]
Given the equation, 5x + 22 = 27:

The goal is to isolate the variable. Hence, a few mathematical operations are necessary to solve for the value of x.

Start by subtracting 22 both sides:
5x + 22 - 22 = 27 - 22
5x + 0 = 5
5x = 5


Next, divide both sides by 5 to isolate and solve for the value of x:

5x/5 = 5/5

x = 1

In order to verify whether x = 1 satisfies the give equation, we must substitute its value into the given equation:

5x + 22 = 27

5(1) + 22 = 27
5 + 22 = 27
27 = 27 (True statement. This implies that x = 1 is the correct value that satisfies the equation).

Therefore, the correct answer is x = 1.
