Answer:
x = 4.5
Step-by-step explanation:
6x+7=4x+4y
The first step is to simplify the equation by combining the x terms
Subtract 4x from each side
6x-4x +7 = 4x-4x+4y
2x+7 = 4y
We know the y value is 4
Substitute y=4 into the equation
2x+7 = 4(4)
2x+7 =16
Subtract 7 from each side
2x+7-7 =16-7
2x=9
Divide by 2
2x/2 =9/2
x= 4.5
Answer:
74°F
Step-by-step explanation:
In order to find the average of a certain amount of numbers, you add those numbers together and divide by how many numbers there are. In this case, you would reverse that method to find the last number. We know that there were four readings, and we have three of them and the average. Multiply the average (84.75) by the number of readings (4), and you get the sum of all the readings (339). Then you subtract each of the readings that you already know to isolate the last reading. 339 - 112 (first reading) = 227, 227 - 68 (second reading) = 159, and 159 - 85 (fourth reading) = 74. Therefore, the third reading must be 74.

Answer:
7/12
Step-by-step explanation:
When you multiply fractions you just multiply across. 7*6 = 42 and 8*9 = 72. The both of these numbers can be divided by six so 42/6 = 7 as the numerator. 72/6 = 12 for the denominator. 7/12 is the answer.
The answer is Letter C - 1/2,775
The probability of choosing one of them is 2 out of 75 while the probability of choosing the other one is 1 out of 74. 74 band members, not counting the other person (you or your bother).
Computation:
P = 2 / 75 * 1 / 74
= 0.0266... * 0.01351...
= 1 / 2,775
You can also multiply 75 with 74 to get a total of 5,550 then divide it by 2 students to be selected to get 2,775. Meaning one out of 2,775 possibilities.
