Answer:
Step-by-step explanation:
We know that A and B are complementary angles. So, they must add up to 90°. As an equation:
Since we know their equations, substitute:
Solve for x. Combine like terms on the left:
Subtract 9 from both sides:
Divide both sides by 9:
So, the value of x is 9.
We want to find A. So, let's use the equation for A:
Substitute 9 for x:
Add:
So, the measure of A is 17°.
2x+2≥20
2x≥18
x≥9
closed circle on 9 because of the = in ≥ and the line going off to the right

Answer:
6327
Step-by-step explanation:
2109 bpm. you want to know how many times in minutes
Well all you do is 2109*3=6327
The cross products of the proportion are equal.
According to the question, Sonny's equation can be written as follows.
16/x = 48/15
Now, the variable x is replaced by the constant 5. So the equation can now be written as follows.
16/5 = 48/15
When two fractions are equal to one another as shown above, the constants are cross multiplied with one another in order to form an equation.
16*15= 48*5
The values of both the products are equal which is 240.
Therefore, because the cross products of the proportion are equal.
