Answer:
8
Step-by-step explanation:
22-12+4-6 = 8
<h2><u>Solve for x</u></h2>
<h3>what are the steps to solve this?</h3><h3>9+6(x-5)=10-3(x-7)</h3>
<u>Step 1:</u> Apply distributive property.
- 9 + 6(x - 5) = 10 - 3(x - 7)
- 9 + 6x - 30 = 10 - 3x + 21
- -21 + 6x = 31 - 3x
<u>Step 2:</u> Combine all like terms.
- -21 + 6x = 31 - 3x
- -21 - 31 = -6x - 3x
- -52 = -9x
<u>Step 3:</u> Divide both sides of the equation by -9 and simplify.
<u>Answer:</u>
- The value of x is <u>52/9</u>.

Answer:
a) N = 240 ways
b) N = 303,600 ways
c) N = 10 ways
Step-by-step explanation:
a) Given
General course consist of one course from each of 4 groups.
Social Science = 5 options
Humanities = 4 options
Natural sciences = 4 options
Foreign language = 3 options.
Therefore the total number of possible ways of selecting one each from each of the 4 groups is:
N = 5×4×4×3 = 240 ways
b) if four people are chosen from 25 member for four different positions, that makes it a permutation problem because order of selection is important.
N = nPr = n!/(n-r)!
n = 25 and r = 4
N = 25P4 = 25!/(25-4)! = 25!/21!
N = 303,600 ways
c) The number of ways by which 5 tosses of coin can yield 2 heads and 3 tails.
N = 5!/(5-5)!(2!)(3!)
N = 5×4/2
N = 10 ways
Step-by-step explanation:
4 + n + 7m
constants are just the numbers with no variables (letters)
so the constant is 4
coefficients are numbers multiplied by variables (letters)
so the coefficients are : 7 and 1
the error sarah made is forgetting the coefficient of n......because even if it is not written, n is the same as 1n....so basically, there is a coefficient for EVERY variable, even if its not written.
