Supplementary means that they add up to 180 degrees. Those 2 angles should add up to 180 degrees. X is the missing angle and 42 degrees is the other angle. If both are added together they equal 180. To find x we can simply subtract 42 from 180 to get the x. 138 is x. The proof is that if 138 and 42 are added together they end up making 180 degrees. Therefore, the answer is 138
Answer:
-2(-2) + (12-9) = 2 + 9 + -2(-2)

Answer:
a) 19 batches
b) $0.18
Step-by-step explanation:
A 4-pound bag of sugar contains 4 54 one-teaspoon servings and costs $3.49. A batch of muffins uses 1/2 cup of sugar.
1 cup = 48 teaspoons
a) How many whole batches can you make if you use as much of the sugar as possible?
1 batch = 1/2 cups of sugar = 24 teaspoons of sugar
Hence,
24 teaspoons of sugar = 1 batch
454 one-teaspoon servings = x
Cross Multiply
24 × x = 1 × 454
x = 454/24
x = 18.9166666667
Approximately to whole batches = 19 batches
b) What is the cost of sugar for each batch?
454 one-teaspoon servings and costs $3.49 = 19 batches
Hence
19 batches = $3.49
1 batch = x
x= $3.49/19
x = $0.18368421052
Approximately = $0.18
Answer:
a) The unit rate of change of d with respect to t is equal to 1.6
b) the graph of the line in the attached figure.
Answer:
B
Step-by-step explanation:
2x + 4y = 6x - y
4y + y = 6x - 2x
5y = 4x
(4,5) when x=4, y=5
5(5) = 4(4)
25 = 16
is a false statement, so not (4,5)
(5,4) when x=5, y=4
5(4) = 4(5)
20 = 20
is a true statement, so yes
