Answer:
x=4
Step-by-step explanation:
-3x + 12x =36
Combine like terms
(-3+12)x = 36
9x = 36
Divide each side by 9
9x/9 = 36/9
x = 4
Answer:
Weight of nuts = 6 pounds.
Weight of cereal squares = 6 pounds.
Step-by-step explanation:
Let the weight of nuts used in the trial mix to be x pounds and the weight of cereal squares used in the trial mix to be y pounds. Total weight of the mixture is 12 pounds. Therefore: x + y = 12. This implies y = 12 - x (Equation 1).
Cost of nuts per pound = $8 and cost of cereal squares per pound = $3. Cost of the mixture per pound = $5.5. Total mixture = 12 pounds. Since x pounds of nuts and y pounds of cereal squares are used, therefore: 8x + 3y = 5.5 * 12.
8x + 3y = 66. (Equation 2).
Put equation 1 in equation 2.
8x + 3(12 - x) = 66.
8x + 36 - 3x = 66.
5x = 30.
x = 6.
Put x = 6 in equation 1.
y = 12 - 6.
y = 6.
Therefore, the weight of nuts used in the trial mix will be 6 pounds and the weight of cereal squares used in the trial mix will be 6 pounds!!!
The answer is C) 7.
In function 1, there is no rate of change.
In function 2, there is a rate of change of 7.
This leaves 7 as the only possible answer.
Answer:
this is an obtuse angle and an isosceles triangle
because angle is greater than 90° and two sides are equal.
