The property used is B: addition property
Step-by-step explanation:
The addition property of equality states that if you add the same number to both sides of an equation, the equation balances.In this case;
5x-9<91------------performing addition property of equality
5x-9+9<91+9
5x<100----------performing division property
5x/5<100/5
x<20 ------answer

Answer:
-12 3/5
Step-by-step explanation:
-4 3/10 - 8 3/10
The signs are the same so we add and then take the sign
4 3/10 + 8 3/10
Add the whole numbers
4+8 = 12
Add the fractions
3/10 + 3/10 = 6/10
Simplify the fraction
6/10 = 3/5
Put them together
12 3/5
Add the sign
-12 3/5
Y= 1x+ 3
1x is the slope and 3 is the y intercept
I did rise over run to find the slope 3/3=1
Y is 3 because y intercept is when a line go through the y axis and it’s on 3
hope this helps!
Answer:
Probability of having at least 4 Girls
= 0.6875
Step-by-step explanation:
Probability of having at least 4 Girls is 1-probability of having exactly 3 girls
Total number of children= 5 = N
Probability of having a girl p = 0.5
Probability of not having a girl q= 0.5
X= 3
Probability of at least 4 girls is given by
Probability= NCX(p)^x(q)^(N-x)
Probability = 5C3(0.5)^3(0.5)^(5-3)
Probability = 5C3(0.5)^3(0.5)^2
Probability= 5!/3!2!(0.5)^3(0.5)^2
Probability= 10(0.125)(0.25)
Probability= 0.3125
Probability of having at least 4 Girls
= 1- 0.3125
= 0.6875
The solution is x = 36, and the sum of the digits is 3 + 6 = 9.

How to find the value of the number?</h3>
We know that, if we define x as the number, we have:
x + x^2 + √x = 1338
Now we need to find the value of x.
Trivially, we can graph the function:
y = x + x^2 + √x
We can see that the solution of x + x^2 + √x = 1338 is
x = 36
36 + 36^2 + √36 = 1338
Then the sum of the digits of the number is 3 + 6 = 9
