Answer: 9: c , 10: a ,11 :d 12: a
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
First, solve so that y is alone on its side of the equation by dividing both sides of the equation by 12.
12y=(-24)x
y=(-2)x
Therefore, the slope must be -2.
Answer:
y=17/2 y=5/2

Answer:
Step-by-step explanation:
Measures of angles are,
m∠A = (2x)°
m∠B = (x + 14)°
m∠C = (x - 38)°
By triangle sum theorem,
m∠A + m∠B + m∠C = 180°
2x + (x + 14) + (x - 38) = 180
(2x + x + x) + (14 - 38) = 180
4x - 24 = 180
4x = 204
x = 51
m∠A = 2(51)° = 102°
m∠B = (51 + 14)° = 65°
m∠C = (51 - 38)° = 13°
The formula for this is m = 4a + 2c, where c = number of children; m = number of meatballs; a = number of adults.
m = (4 x 10) + (2 x 5)
simplify,
40 + 10 = 40
The answer to this is 40 meatballs.
