Answer:
x = 25
Step-by-step explanation:
4x+50 and 150 are vertical angles which means they are equal.
4x+50 =150
Subtract 50 from each side
4x+50-50 = 150-50
4x = 100
Divide each side by 4
4x/4 = 100/4
x = 25
Answer:
Step-by-step explanation:
a)
x= gourmet pretzels
y= boxes of strawberries
system will be:
b)
a box of strawberries is 6.5
22/7 = 3.142857...
Let's see if we can beat this using a fraction with 113 as its denominator.
-------
3 x 120 = 360
-------
So, let's try out x = 360:
360/113 = 3.185.... (Too high)
How about x=350:
350/113 = 3.097... (Too low)
Let's try out x = 355:
355/113 = 3.14159292 (Calculator value)
--------
Let's now compare 22/7 and 355/113 to pi:
22/7 = 3.142857...
355/113 = 3.14159292 (Calculator value)
π = 3.141592654
-------
As we can see, 355/113 provides us with a better approximation of π. This means that x=355.
Answer:A positive correlation is a relationship between two variables such that their values increase or decrease together.
Step-by-step explanation:
Answer:
39,960 is divisible by all of the listed numbers.
Step-by-step explanation:
The sum of digits is 3+9+9+6+0 = 27, and the sum of those digits is 2+7=9.
This tells you the number is divisible by 3 and 9.
The number is even and ends in 0. Together with divisibility by 3, this tells you the number is divisible by 6. The 0-ending tells you the number is divisible by 2 and 5 and 10.
The last two digits are 60, a number that is divisible by 4, so the number is divisible by 4.
39,960 is divisible by all of the numbers listed: 2, 3, 4, 5, 6, 9, 10.
