Answer:
The greatest common divisor (gcd) of two or more numbers referst to the largest positive integer that divides each of the integers. Also, two integers are said to be relatively prime, mutually prime, or coprime if the only positive integer that divides both of them is 1. Therefore, If the GCD of 5 and 12 is one, it means that the two numbers are mutually prime.
$4.90 Each cake cost 0.70$ so 7x7=49 add the zero and move decimal one place to left
= 4.90$
Answer:
- 23/13
Step-by-step explanation:
1. Subtract 5/2 from both sides of the equation.
2. Simplify
7/5 = /10 − 23/10
3. Multiply all terms by the same value to eliminate fraction denominators.
7/5 = /10 − 23/10 2 ⋅ 5 ⋅ 7/5 = 2 ⋅ 5( /10 − 23/10)
4. Simplify
14 = − 23
5. Subtract from both sides of the equation.
14 = − 23 14 − = − 23 −
6. Simplify
13 = − 23
7. Divide both sides of the equation by the same term.
13<em>x </em>= −23 13x/13 = -23/13
8. Simplify
= −23/13
The stem and leaf diagram is shown below
There are a total of 48 data
Question a:
The frequency in the stem for 9 to 9.9 is 13 data
Question b:
The location of the first quartile is given by
, where 'n' is the number of data
We have n = 48
Location of the first quartile is at
rounded down to 12
The value of the lower quartile is on the
on the diagram which is 8.7
if this trapezoid is to scale, then the scale factor between the shortest and longest side is 1.5
so, that means that 1.5(2x+6) = 4x+2
so, your equation becomes 3x+9 = 4x+2
if you subtract 2 from each side, you get 3x+7 = 4x
meaning that x = 7
i hope this helps, and i'm sorry if it's wrong!! :)
