Answer:
252 = 22 × 32 × 7;
58 = 2 × 29;
Multiply all the prime factors, by the largest exponents.
Least common multiple:
lcm (252; 58) = 22 × 32 × 7 × 29;
lcm (252; 58) = 22 × 32 × 7 × 29 = 7,308
the numbers have common prime factors
Answer:
problem 1: h=a/b problem 2: 5
Step-by-step explanation:
First problem: a=bh
First you have to flip the equation so bh=a
Next you have to divide both sides by b.
bh/b=a/b
so h=a/b
Second problem: 45ft is the area and 9ft is the base so to find the height you have to divide the area by the base
If you only have the base and height you would multiply them to find the area. If you only have area and height you divide area by height to get base.
You have to divide 45 by 9, the answer would be 5.
Hope this helped!
5y=95
y=95/5(vertically opppsite angles)
5x=85
x=85/ 5(vertically opppsite angles)
Answer:
A) 8
Step-by-step explanation:
The average of two numbers is 7.
6 and x have an average of 7.
sum of terms / number of terms = average
(6 + x)/2 = 7
6+x = 14
x = 8
The number is 8.
Answer
She used 6/15 litres of oil in January
Explanation
We are given that, in January, she used 3/5 of the amount of oil she used in February.
