Answer:
15 or 16. 54 is not listed.
Step-by-step explanation:
pretend that 11 is 0. that means 54 is 43.
then you do 43 divided by 3 or 43/3
but looks like the number 43 isn't divisible. it is 14.33333 repeating decimal.
Same if you really use your time and count. So i dont know if u meant 53 it will be 53 if you meant 56 it will be 16.
Answer:
1
Step-by-step explanation:
We need to find the factors of 18 and 35
Breaking into prime factors
18 = 2*9 = 2*3*3
35 = 5*7
There are no common factors so the greatest common factor is 1
Answer:
14x + 7 = 30
Step-by-step explanation:
Given
7y + 6 = 36 and y = 2x + 1
substitute y = 2x + 1 into 7y + 6 = 36 , that is
7(2x + 1) + 6 = 36 ( subtract 6 from both sides )
7(2x + 1) = 30 ← distribute parenthesis on left side by 7
14x + 7 = 30
Area = length X width
A = L(12 ft) x W(9 ft) but since the cost of carpet is given in square yards not square feet we need to convert
A = (12 ft)(1 yd/3 ft) x (9 ft)(1 yd/3 ft) 1 yard = 3 feet so 1 foot = 1/3 yard
A = 4 yd x 3 yd divide by 3 ft which cancels the original ft and leaves yd's
A = 12 square yards
Cost = Area x price per yard
Cost = 12 sq yd X $35.00/ sq yd multiply and the sq yd's cancel leaving just cost in dollars
Cost = $420.00
Answer:
c
Step-by-step explanation:
let the number be n then multiplied by itself gives n², thus
n² + 7 = 16 ( subtract 7 from both sides )
n² = 9 ( take the square root of both sides )
n = 
= 3
