Answer:
C
Step-by-step explanation:
Expand the factors and compare the coefficients of like terms.
Given
(mx + 2)(3x - 5) ← expand using FOIL
= 3mx² - 5mx + 6x - 10
Compare to 12x² - 14x - 10
For the 2 to be equal, then the coefficients of like terms must be equal.
Compare coefficients of x² terms
3m = 12 ( divide both sides by 3 )
m = 4 → C

You are testing two scales for accuracy by weighing two different objects.
Use the drop-down menus to complete the statements about the scales' accuracy.
Answers
Answer:
This is because the object on the 1st scale weighs (more) than the object on second scale, each pound of error results in a (lesser) percent error. The first scale was (10) pounds off the second scale,was (3) pounds off, so 1st scale was (10)% off 2nd scale was (12)% off.
Answer:
Because the object on Scale 1 weighs more than the object on Scale 2, each pound of error results in a lesser percent error. Scale 1 was 10 pounds off and Scale 2 was 3 pounds off, so Scale 1 was 10% off and Scale 2 was 12% off.

A ,B and C average is 45 ,b and C average is 40 then find b
Answers
This question is incomplete
Complete Question
The average weight of A, B and C is 45 kg. If the average weight of A and B be 40 kg and that of B and C be 43 kg, then the weight of B is :
Answer:
31 kg
Step-by-step explanation:
From the above question:
A ,B and C average is 45.
Hence, the total values of A, B, C is calculated as:
A + B + C /3 = 45
A + B + C = 45 × 3
A + B + C = 135
Also,
B and C average is 43
The total values of B, C is calculated as:
B + C /2 = 43
B + C = 43 × 2
B + C = 86
A and B average is 40
The total values of A, B is calculated as:
A + B /2 = 40
A + B = 40 × 2
A + B = 80
Hence:
A + B + C = 135
B + C = 86
A + B = 80
Hence, we can solve for A, we substitute 80 for A + B
80 + C = 135
C = 135 - 80
C = 55kg
B + C = 86
B + 55 = 86
B = 86 - 55
B = 31 kg

The ratio of band students to choir students is 4:6. There are a total of 60 students in the band and choir. How many students are in the band?
Answers
Answer:
24
Step-by-step explanation:
Given that:
The ratio of band students to choir students is 4 : 6.
Total number of students in the band and choir combined = 60
To find:
The number of students in the band = ?
Solution:
First of all, let us understand the meaning of the ratio given.
Ratio of 4 : 6 means there are 4 number of band students for every 6 number of choir students.
Also, number of band students will be in the multiples of 4 only and
number of choir students will be in the multiples of 6 only
Let the total number of band students = 4[tex]x[/tex]
Let the total number of choir students = 6[tex]x[/tex]
Total number of students = 60
As per question statement, we can write the following equation:
[tex]\Rightarrow 4x+6x=60\\\Rightarrow 10x = 60\\\Rightarrow x =6[/tex]
Total number of band students = 4 [tex]\times[/tex] 6 = 24

A baseball team has a 20-person roster. A batting order has nine people. How many different batting orders are there
Answers
Answer:
60,949,324,800
Step-by-step explanation:
We solve the above question using Permutation formula
The formula for Permutation =
nPr = n!/(n - r)!
Total Amount in a Set (n) = 20 persons
Amount in each Sub-Set (r) = 9 batting order
Hence:
20P9 = 20!/(20 - 9)!
= 60,949,324,800
Therefore, the different batting orders they would have are: 60,949,324,800
