5. 
First plug the value of x into the equation
 2(-2y-12)+y=9
then solve for y
2(-2y)+2(-12)+y=9 \\ -4y+(-24)+y=9 \\ -4y-24+y=9 \\ -3y-24=9 \\ -3y=33 \\ \frac{-3y}{-3}= \frac{33}{-3} \\ y = -11

6. Do the same steps 
5(-y-1)+y=-13 \\ 5(-y)+5(-1)+y=13 \\ -5y+(-5)+y=13 \\ -5y-5+y=13 \\ -4y-5=13 \\ -4y=18 \\ \frac{-4y}{-4}= \frac{18}{-4} \\ y=-4.5

I need step by step explanation for this!!
Naily [24]

Hello! :)

Answer:

\huge\boxed{751}

Let the smallest digit, or the units' digit, be equal to x:

Tens' digit is four more, therefore:

x + 4 represents the tens' digit.

Hundreds' digit is 2 more than the tens' digit, so:

2 + (x + 4), or x + 6 represents the hundred's digit.

These all sum up to 13, so write an expression to represent this:

x + (x + 4) + (x + 6) = 13

Combine like terms:

3x + 10 = 13

Subtract 10 from both sides:

3x = 3

Divide both sides by 3:

x = 1

Find the digits using the rules listed above:

Hundreds' digit: (1) + 6 = 7

Tenths' digit:  (1) + 4 = 5

Units' digit: 1 = 1

Therefore, the number is:

751.

Jessie designed a sculpture that is shaped like a circle. The circumference of the sculpture is 10π meters. Which measurement is
BlackZzzverrR [31]

Answer:

25πm²

Step-by-step explanation:

Circumference of the circular sculpture = πd

d is the diameter

Given

Circumference = 10π metres

Substitute into the formula

10π = πd

10 = d

d = 10m

Area of the sculpture = πd²/4

area of the sculpture = π(10)²/4

area of the sculpture = 100π/4

area of the sculpture = 25π m²

Hence the measurement closest to the area of the sculpture in square meters is 25πm²
