First, you have 3x-1 + 2x+1
Combine like terms and the 1’s cancel each other out. You are left with 5x.
Then, you add x+2 + x+1
Combine like terms and you have 2x+3
Add 5x + 2x+3 and you have 7x +3
I’m bad at explaining, so here are the steps.

Tina is packing for a five-day trip. She has one blue, one red, one white, one green, and one grey t-shirt. Tina will not wear each t-shirt more than once. What is the probability that Tina will wear blue on the first day of her trip and then wear grey on the second day of her trip?

1/25
Answers
The probability of Tina wearing blue on the first day of her trip and then wearing grey on the second day of her trip is 1/20.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The probability of Tina wearing blue on the first day of her trip is 1/5, since she has 5 t-shirts to choose from and only one of them is blue.
After wearing the blue t-shirt on the first day, Tina will have 4 t-shirts left to choose from for the second day. Only one of those t-shirts is grey, so the probability of Tina wearing grey on the second day given that she wore blue on the first day is 1/4.
The probability of both events happening (Tina wearing blue on the first day and then grey on the second day) is the product of the individual probabilities:
P(blue on first day and grey on second day) = P(blue on first day) x P(grey on second day | blue on first day)
P(blue on first day and grey on second day) = (1/5) x (1/4)
P(blue on first day and grey on second day) = 1/20
Therefore, the probability of Tina wearing blue on the first day of her trip and then wearing grey on the second day of her trip is 1/20. So, the correct option is 1/20.

Which value from the set {1/2, 2/3, 4/3, 5/2} is a value of x that will the equation 3/4 ÷ × = 9/8 true?
Answers
Answer:
2/3
Step-by-step explanation:
To find out what x is in this case, divide 3/4 by 9/8.
3/4 / 9/8
Dividing by a fraction is the same as multiplying it's inverse.
3/4 * 8/9
Cross cancellation (3 & 9 (GCF: 3); 4 & 8 (GCF: 4)
1/1 * 2/3
We can remove the 1/1.

2/3 is the value of x that will make 3/4 ÷ x = 9/8 true.
Find the missing angle in a triangle with the given sides.
Answers
Answer:
[tex] \angle[/tex]Z = 1°Step-by-step explanation:
Since the shape is a triangle it means that all it's interior angles sum to 180°
To find the missing angle sum up the known angles and subtract them from 180°
That's
[tex] \angle[/tex]X + [tex] \angle[/tex]Y + [tex] \angle[/tex] Z = 180°
89° + 90° + [tex] \angle[/tex]Z = 180°
[tex] \angle[/tex]Z = 180 - 179°
We have the final answer as
[tex] \angle[/tex]Z = 1°Hope this helps you
Answer:
1°
Step-by-step explanation:
Given angles
<x=89°<y=90°We know that in a triangle
Sum of angles=180°[tex]\rm \mapsto \angle x + \angle y + \angle z = 180 \\ \rm \mapsto89 + 90 + \angle z = 180 \\ \rm \mapsto179 + \angle z = 180 \\ \rm \mapsto\angle z = 180 - 179 = 1[/tex]

A. higher, lower?
B. same as, twice, half?
Answers
Answer: A
Step-by-step explanation: mean in math terms mean everything added together on a graph we now have an 8th grade class and a 7th grade class the 7th-grade class has 67 pets 6+14+15+16+10+6=67 and the 8th-grade class has 121 pets 3+8+21+36+35+18=121 so it would be A.
the mean number of pets for the 8th-grade class is about 1.4 pets higher than the mean number of pets for the 7th grade class. This different is about lower the mean absolute deviation of either group.
