Answer:
Step-by-step explanation:
54/45 = 1 9/45 = 1 1/5
which is one and one fifth
Answer:
x=9
Step-by-step explanation:
80+6x+16=17x-3
=>17x-3-6x-16=80
=>11x-19=80
=>11x=80+19
=>11x=99
=>x=99/11
therefore
x=9
Answer: 1. 
2. 
Step-by-step explanation:
The given division problems :
By long division (see the attachment)
1. Divisor= 2
Dividend =456
Quotient = 228
Remainder =0
So,
2. Divisor= 7
Dividend = 538
Quotient =76.85
so,
Answer:
(x - 3)(5x - 3)
Step-by-step explanation:
Assuming you require the expression to be factorised.
Given
5x² - 18x + 9
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 5 × 9 = 45 and sum = - 18
The factors are - 15 and - 3
Use these factors to split the x- term
5x² - 15x - 3x + 9 ( factor the first/second and third/fourth terms )
= 5x(x - 3) - 3(x - 3) ← factor out (x - 3) from each term
= (x - 3)(5x - 3) ← in factored form
Answer:
315
Step-by-step explanation:
because 15% of 2,100 is 315
