Helpppp will give brainly
Answer:
y=27.75
x=13.5
Step-by-step explanation:
(5x-17)+(3x-11)=180 (supplementary angle rule)
8x-28=180
8x=180+28
x=108/8
x=13.5
(3x-11)+90+(2y+5)=180 (supplementary angle rule)
29.5+90+2y+5=180 (replace x by 13.5)
2y=55.5
y=55.5/2
y=27.75

Two angles are complementary if their sum is 90°. If the measure of the first angle is x°, and
the measure of the second angle is (3x - 2)°, find the measure of each angle.
Answer:
The first angle is 23°, the second angle is 67°Step-by-step explanation:
x° - measure of first angle
(3x-2)° - measure of second angle
Their sum is 90° so
x + 3x - 2 = 90
+2 +2
4x = 92
÷4 ÷4
x = 23
3x-2 = 3•23 - 2 = 69 - 2 = 67
Checking: 23+67 = 90

Answer:

Step-by-step explanation:
Amy is six years older than her brother Leo. Leo is seven years old. If n stands for Amy's age, which of these sentences could be used to find her age?
Answer:
n = 6+x
Step-by-step explanation:
Given that:
Amy is 6 years old than her brother Leo
Let consider the age of Leo to be x since we are not yet told how old is Leo
Then Amy is 6+x
Now, we know that Leo is seven years old,
i.e x = 7
If n stands for Amy's age,
Then, the algebraic expression showing how old is Amy's age can be expressed as n = 6+x
Amy's age (n) = 6+7
Amy's age (n) = 13
To solve any word problem, we need to define our conditions into system of the equations. Thus, Amy's age is 13 years.
Amy is six years older than her brother Leo.
Leo's age is seven years.
It is given in the question that Amy's age stands for 'n'.
Thus, according to the given conditions from the question.
The expression that defines the age of Amy is given below.
[tex]\rm{Amy's\;Age}=7+\rm{Leo's\;Age}\\n=7+6\\n=13[/tex]
Thus, Amy's age is 13 years.

A computer generates 90 integers from 1 to 5 at random. The results are recorded in the table.
What is the experimental probability of the computer generating a 1?
10%
20%
30%
40%
Outcome Number of times
outcome occurred
1 36
2 11
3 13
4 12
5 18
Answer:
40%
Step-by-step explanation:
36/90 integers are 1, so the experimental probability is ...
p(1) = 36/90 = 0.40 = 40%
Using it's concept, it is found that there is a 0.4 = 40% experimental probability of the computer generating a 1.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
For an experimental probability, these numbers of outcomes are taken from previous trials. In this problem, there have been 90 trials, and 36 resulted in a 1 being generated, hence:
p = 36/90 = 0.4.
0.4 = 40% experimental probability of the computer generating a 1.

Given the original statement "If a number is negative, the additive inverse is positive,” which are true? Select three options. If p = a number is negative and q = the additive inverse is positive, the original statement is p → q. If p = a number is negative and q = the additive inverse is positive, the inverse of the original statement is ~p → ~q. If p = a number is negative and q = the additive inverse is positive, the converse of the original statement is ~q → ~p. If q = a number is negative and p = the additive inverse is positive, the contrapositive of the original statement is ~p → ~q. If q = a number is negative and p = the additive inverse is positive, the converse of the original statement is q → p.
Answer:
A. If p = a number is negative and q = the additive inverse is positive, the original statement is p → q.
B. If p = a number is negative and q = the additive inverse is positive, the inverse of the original statement is ~p → ~q.
D. If q = a number is negative and p = the additive inverse is positive, the contrapositive of the original statement is ~p → ~q.

what are the midpoint between this two points
(-1,-5) and (-5,9)
Hey there! I'm happy to help!
To find the x value of the midpoint, you add the x values and divide by 2.
-1-5=-6
-6/2=-3
For the y value, you add the y values and divide by 2.
-5+9=4
4/2=2
Therefore, the midpoint is (-3,2).
