The other person didn’t explain so I will:
Plz give me brainliest.
So if we rotate them to be equivalent
4y-4 = 28
Add 4 to both sides
4y = 32
Divide by 4
Y =8

10x + 65 = 135
Minus 65 from both sides
10x = 70
Divide by 10 from both sides
X=7

If you roll a dice and flip a coin, what is the probability you will land on a number greater than 4 and a heads?

irinina [24]

Answer:

you have a 7/12 chance

Step-by-step explanation:

The sample space has 12 elements:

T1, T2, T3, T4, T5, T6

H1, H2, H3, H4, H5, H6

(From a combinatorics perspective, there are 2 options for the coin and 6 for the die for a total of 2 * 6 = 12.)

There are 6 heads results and one tales result that has a 4 for a total of 7 possibilities that meet your criteria. That makes the probability 7 / 12.

The given in the problem above is an arithmetic sequence with the first term equal to 4 and the common difference is 5. To determine the number of seats on row 23, use the formula,

an = a1 + (n - 1) d

Solving for the 23rd term,

an = 4 + (22) 5 = 114 seats

Therefore, the answer is there are 114 seats on the 23rd row.

Solve 3|x -6| = 12.

Orlov [11]

Answer:

$\boxed{C. \: x = 2}$

Step-by-step explanation:

$= > Solve \: for \: x \: over \: the \: integers: \\ 3 |x - 6| = 12 \\ \\ = > Divide \: both \: sides \: by \: 3: \\ |x - 6| = 4 \\ \\ = > Split \: the \: equation \: into \: two \: possible \: cases: \\ x - 6 = 4 \: \: \: \: \: \: \: or \: \: \: \: \: \: \: \: x - 6 = -4 \\ \\ = > Add \: 6 \: to \: both \: sides: \\ x = 10 \: \: \: \: \: \: \: \: or \: \: \: \: \: \: \: \: x = 2 \\ \\ Answer: x = 10 \: \: \: \: \: \: \: \: or \: \: \: \: \: \: \: \: x = 2$

Two groups went bowling. Here are the scores from each group.

vladimir2022 [97]

Answer:

Group A has greater variability

Step-by-step explanation:

Group A: 80, 100, 190, 110, 70, 90, 130

The variability of group A data :

Taking the range :

Maximum = 190 ; Minimum = 70

Range = Maximum - Minimum ; 190 - 70 = 120

Group B : 50, 110, 100, 120, 107, 140, 150

The variability of group B data :

Taking the range :

Maximum = 150 ; Minimum = 50

Range = Maximum - Minimum ; 150 - 50 = 100

Hence, Group A has greater variability
