Thanks, you have a great day and a merry Christmas too
Answer:
3
Step-by-step explanation:
the answer is 3, because you always have to add the numbers in paranthises first. and 5+3= 8. u bring down the -5 and you have -5 + 8 = 3.
Answer:
B. Add 2/5 to both sides
Step-by-step explanation:
Yuu have to add because it says subtract. inverse operations
Problem 1
<h3>Answer: C. lines a and b</h3>
Explanation: Circle or highlight the angles 10 and 15. They are alternate interior angles with line d being the transversal cut. It might help to try to erase line c to picture the transversal line d better. With d as the transversal, and angles 10 and 15 congruent, this must mean lines a and b are parallel by the alternate interior angle theorem converse.
==============================================
Problem 2
<h3>Answer: D. no</h3>
Explanation: The angles at the top are 32 degrees, 90 degrees, and x degrees which is the missing unmarked angle at the top (all three angles are below line m). The three angles must add to 180 to form a straight angle
32+90+x = 180
x+122 = 180
x = 180-122
x = 58
The missing angle is 58 degrees. This is very close to 57 degrees at the bottom. Though we do not have an exact match. This means lines m and n are not parallel. The alternate interior angles must be congruent for m and n to be parallel, as stated earlier in problem 1.
Answer:
5/78 chance to get a Nickel and then a penny without replacing
Step-by-step explanation:
The bag contains a total of 40 coins which show that the probability of getting a Nickel is 5/40 and the probability of getting a penny after taking out a nickel is 20/39. In order to find the Probability of two events together you must multiply the probabilities so
(5/40) * (20/39) = 100/1560 = 5/78
