The perimeter is
$2(2z+3z-3)=44$
$\Rightarrow 2(5z-3)=44$
$\Rightarrow 10z-6=44$
$\Rightarrow 10z=50$
$\Rightarrow z=5$

The length of AB is
$3z-3=3(5)-3=15-3=12$

Step-by-step explanation:

The slope of the line passing through two points is given by,

$\frac{y2 - y1}{x2 - x1}$

13)

$\frac{(0 - y)}{(0 - 2)} = (\frac{ - 3}{2} )$

$\frac{ - y}{ - 2} = \frac{ - 3}{2}$

$y = - 3$

option D

14)

$\frac{ ( - 3 - y)}{(1 + 5)} = \frac{ - 1}{6}$

$\frac{ - 3 - y}{6} = \frac{ - 1}{6}$

$- 3 - y = - 1$

$- y = - 1 + 3 = 2$

$y = - 2$

option C

15)

$\frac{(y - 4)}{( - 5 + 1)} = \frac{1}{4}$

$\frac{y - 4}{ - 4} = \frac{1}{4}$

$- y + 4 = 1$

$- y = 1 - 4 = - 3$

$y = 3$

option B

16)

$\frac{(y + 3)}{( - 4 - 3)} = \frac{ - 3}{7}$

$- (y + 3) = - 3$

$y = 3 - 3 = 0$

option C

Someone help and please answer it fully

Answer:

No, Matt did not solve the equation correctly

Correct Answer: x = 8

Step-by-step explanation:

4(x + 2) = 30

Step 1: Distribute

4x + 2 = 30 $=>$ This is his mistake, he should completely distribute 4

to x and 2

Step 2: Subtract 2 from both sides/Isolate x

4x = 28 $=>$ This part is done correctly, but wrong because of Step 1

Step 3: Divide both sides by 4

x = 7 $=>$ This is correct, but again, he messed up on Step 1

<h3>Let's find the correct answer to this equation:</h3><h3>4(x +2) = 30</h3>

Step 1: Distribute

Remember to distribute 4 to all terms in the parenthesis.

4(x + 2) = 4(x) + 4(2)

= 4x + 8

4x + 8 = 30

Step 2: Subtract 8 from both sides/Isolate x

Move all the terms that do not belong to x to the other side. We can do this by subtracting 8 from both sides $=>$ (opposite operation of adding 8)

4x + 8 = 30

4x = 30 - 8

4x = 32

Step 3: Divide both sides by 4/Isolate x

Now we want x by itself. Since x is being multiplied by 4, we have to use the opposite operation, dividing by 4, to have x on one side by itself

4x = 32

4(x) = 32

x = 32 ÷ 4

x = 8

Scott and Tom rent a boat at Stow Lake. They start at 10:15 and end at 11:45. The boat rental costs $1.50 for every 15 minutes.

dem82 [27]

Answer:they would pay a total amount of $9

Step-by-step explanation:

Scott and Tom rent a boat at Stow Lake. They start at 10:15 and end at 11:45. The number of hours for which they rented the boat would be

11:45 - 10:15 = 1 hour 30 minutes = 1.5 hours.

Converting to minutes, It becomes

60 + 30 = 90 minutes.

The boat rental costs $1.50 for every 15 minutes. Therefore, the total amount of money that they would pay is

90/15 × 1.5 = $9
