Can someone simplify it or expand it please I need it in like 5 mins !
Answer:
5x+6
Step-by-step explanation:
x-3+7x+21-3x-12
5x+6
[tex] =\tt x - 3 + 7(x + 3) - 3x - 12[/tex]
[tex] =\tt x - 3 + 7x + 21 - 3x - 12[/tex]
[tex] =\tt 7x + x - 3x - 3 - 12 + 21[/tex]
[tex] =\tt 8x - 3x - 15 + 21[/tex]
[tex] \color{plum}=\tt\bold{ 5x + 6}[/tex]
▪︎Therefore :[tex]\color{hotpink} =\tt x - 3 + 7(x + 3) - 3x - 12 \color{plum}=\tt\bold{ 5x + 6}[/tex]

There are 250 bricks used to build a wall that is 20 feet high how many bricks will be used to build a wall is 40 feet high?
Answer:
500 bricks.
Step-by-step explanation:
There are 250 bricks used to build a wall that is 20 feet high how many bricks will be used to build a wall is 40 feet high?
To solve e the above question, we have:
20 feet high = 250 bricks
40 feet high = x bricks

20 feet × x bricks = 40 feet × 250 bricks
x bricks = 40 feet × 250 bricks/20 feet
x bricks = 500 bricks
Therefore, 500 bricks will be used to build a wall is 40 feet high.

16/1 = 9/p
Multiply both sides by 1 to get
16 = 9/p
Multiply both sides by p
16p = 9
Divide both sides by 16
p = 9/16

Answer:
A'(-1, 1), B'(-2, 1), C'(-2, 2) and D'(-1, 3).
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation is reflection, rotation, translation and dilation.
Rotation is the turning of an object about a point. If a point A(x, y) is rotated 90 degrees counterclockwise about the origin, the new point would be A'(-y, x)
From the image attached, the coordinates of polygon ABCD is A(1, 1), B(1, 2), C(2, 2), D(3, 1). If polygon ABCD is rotated 90 degrees counterclockwise about the origin, the new vertices would be at A'(-1, 1), B'(-2, 1), C'(-2, 2) and D'(-1, 3).

Answer:
16 eighteens fit into [tex]\frac{8}{9}[/tex]
Step-by-step explanation:
in order to find out how much eighteenths are the in [tex]\frac{8}{9}[/tex]. we just have to divide [tex]\frac{8}{9}[/tex] by [tex]\frac{1}{18}[/tex]. So we get...
[tex](\frac{8}{9}) /(\frac{1}{18}) = (\frac{8}{9})(18) = \frac{144}{9} = 16[/tex]
