Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 10
Answer:
E is equal to 20 and F is equal to 50. 20(E)+50(F)=70
The probability that a two-digit number selected at random has a tens digit less than its units digit is 0.2667 (4/15).

There are 90 two-digit numbers (99-9). Of these, six numbers are divisible by 15 (15, 30, 45, 60, 75, 90). This is also divisible by 5. Therefore, the preferred case is 30-6 = 24. Therefore, the required probability is 24/90 = 4/15.
The probability of an event can be calculated by simply dividing the number of favorable results by the total number of possible results using a probabilistic expression. Whenever you are uncertain about the outcome of an event, you can talk about the probability of a particular outcome, that is, its potential.

I think the correct answer from the choices listed above is option C. The <span>sum of the measures of the interior angles formed by the boundary of this team pennant should be 180 degrees since all triangles has a sum of interior angles which is 180 degrees. Hope this answers the question.</span>
Answer:
Step-by-step explanation:
5x + y = 9
-10x + 7y = 18
10x + 2y = 18
-10x + 7y = 18
9y = 36
y = 4
5x + 4 = 9
5x = 5
x = 1
(1,4)
answer is D
