Answer:

-12x+16=y

Step-by-step explanation:

Subtract 3 from 11: 8-0.5y=6x

Move 0.5y to the right side: 8=6x+0.5y

Move 6x to the left side: -6x+8=0.5y

Divide both sides by 0.5: -12x+16=y

Carol is painting a four square game court on a school playground. The four small squares are all the same size. If the total ar

Sliva [168]

Given that the total area of the four small squares is 256 ft2, the first thing we are going to do is to divide 256 by 4 and we get 64. So the area of each small square is 64. Now, to find the side length of each small square, we just have to square 64, and the answer is 8. Therefore, the side length of each small square is 8feet. Hope this helps.

The sum of two numbers is 46. The larger number is two less than three times the smaller number. Find the numbers.

melamori03 [73]

Answer: The numbers are: x = 34, y = 12

Step-by-step explanation:

Lets say the numbers are x and y. The two equations are:

x+y=46

x= 3y-2

Next you use substitution for x in the first equation which brings you to

3y-2 + y = 46 which simplyfies to:

4y - 2 = 46

4y = 48

48 / 4 = 12

y = 12

Then you plug back y=12 in either of the equation to solve for x:

x = 3y - 2

x = 3(12) - 2 = 36 - 2 = 34

x = 34, y = 12

Anastaziya [24]

Answer:

16 faults

Step-by-step explanation:

The correct question is

In tennis, a first serve can be an ace, a fault, or it can be returned. In one match, a tennis player hit 24 aces, which was 2/5 of all her first serves. If 1/3 of her first serves were returned, how many of the tennis player's first serves were faults?

Let

x -----> the number of all her first servers

y ----> the number of first services returned

z ---> the number of first services faults

we know that

The number of aces plus the number of returned plus the number of faults must be equal to the number of all her first services

$x=24+y+z$
