Hey are you good at grade 10 physics?
Answer:
10 and 200
Step-by-step explanation:
the two numbers are x and 18x + 20
x + (18x + 20) = 210
19x + 20 = 210
19x = 190
x = 10
Now substitute x = 10 into 18x + 20 to get the second number.
18(10) + 20
180 + 20 = 200
Answer:
B
Step-by-step explanation:
The opposite sides of a parallelogram are parallel and congruent, thus
SR = PQ , that is
8a - 4 = 6a + 10 ( subtract 6a from both sides )
2a - 4 = 10 ( add 4 to both sides )
2a = 14 ( divide both sides by 2 )
a = 7
In a parallelogram consecutive angles are supplementary, thus
∠ P + ∠ Q = 180, that is
18b - 11 + 9b + 2 = 180, that is
27b - 9 = 180 ( add 9 to both sides )
27b = 189 ( divide both sides by 27 )
b = 7
Thus c = a + b = 7 + 7 = 14 → B
Answer:
[-1,6]
Step-by-step explanation:
As stated from the previous question you asked, the range is the range of the Y values.
You also have to be mindful of the closed circles. Closed circles means it is included in the range.
The range is [-1,6]
