Step-by-step explanation:

Take John's sister's age as "x"

So, so twice his sister's age means = 2x

And 5 years more, means = 2x + 5

So finally John's age = 2x + 5

2-3/4z=1/8z+9 please show your steps!

SashulF [63]

1. 2 - 3z/4 = 1/8z + 9 (simplify 3/4z to 3z/4)

2. 2 - 3z/4 = z/8 + 9 (simplify 1/8z to z/8)

3. 16 - 6z = z + 72 (multiply both sides by 8 (the LCM of 4,8)

4. -6z = z + 72 - 16 (subtract 16 from both sides)

5. -6z = z + 56 (simplify z + 72 - 16 to z + 56)

6. -6z - z = 56 (subtract z from both sides)

7. -7z = 56 (simplify -6z - z to -7z)

8. z = 56/-7 (divide both sides by -7)

9. z = -8. (simplify 56/7 to 8)

So in conclusion your answer to the equation would be -8.

A = 4(187*230/2) + 230²
A = 4*21505 + 230²
A = 86 020 + 52 900
A = 138 920 m²

Hope this helps !

Can someone do this whole page please? I REALLY NEED IT!

nordsb [41]

Answer:

1. A(-8,3) B(-8,-2) C(-4,-2)

2. A'(8,3) B'(8,-2) C'(4,-2)

3. A"(-12,1.5) B"(-12,-3) C"(-6,-3)

4. they give you the coordinates, haha. Just graph and connect the dots.

5. Coordinates of ABC: A(-8,3) B(-8,-2) C(-4,-2)

Coordinates of A'''B'''C''': A'''(-3,10) B'''(-3,5) C'''(1,5)

The correct coordinates for a 90 degree rotation is: A''''(3,8) B''''(-2,8) C''''(-2,4)

Most of these are formulas so I hope you have this memorized in preparation for tests! Good luck!
