Answer:
We will get 4 pizza.
Step-by-step explanation:
Each person will eat 3 slices of pizza and we are expecting 16 people to come.So total number of slices consumed by 16 people will be
16×3 = 48 slices.
Now it is given in the question that each pizza has 12 slices then we have to find out number of pizza to be ordered.
We apply unitary method
∵ 12 slices will be = 1 pizza
∴ 1 slice will be = 1/12 pizza
∴ 48 slices will be = 1/12×48
=48/12
= 4 pizza
So total 4 pizza to be ordered.
Answer:
19
Step-by-step explanation:
When 2 chords intersect then the product of the parts of one chord equal the product of the parts of the other chord, that is
12(x - 7) = 4(x + 3) ← distribute parenthesis on both sides
12x - 84 = 4x + 12 ( subtract 4x from both sides )_
8x - 84 = 12 ( add 84 to both sides )
8x = 96 ( divide both sides by 8 )
x = 12
Thus
12 + x - 7 = 12 + 12 - 7 = 17
4 + x + 3 = 4 + 12 + 3 = 19 ← longer chord
Answer:
y = -3/4x -4
Step-by-step explanation:
3x+4y=-16
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
Subtract 3x from each side
3x -3x+4y=-3x-16
4y = -3x-16
Divide each side by 4
4y/4 = -3x/4 - 16/4
y = -3/4x -4
16 + 4x = 10 + 14
16 + 4x = 24.
4x = 24 - 16
4x = 8
x = 8 ÷ 4
x = 2
8x = 2 × 8
8x = 16
Final answer = 16.
