the answer is 3 7/15 sorry if this is really late
y varies directly with x.
The constant of variation is k = 7
Step-by-step explanation:
We have to check whether both vary directly with each other or not.
Every pair of x and y will be considered one by one
If y varies directly with x, it should satisfy y = kx or k = yx
So,
For x= -2, y=-14
For
x=3, y=21
For
x=5, y=35
As k is same for all pairs of x and y, it can be concluded that:
y varies directly with x.
The constant of variation is k = 7

Add em up bro, 600+60+14
pretty sure the answer would be 674
it's like counting your money !
Answer:
.64 < 65 % < 2/3 < 7/10
Step-by-step explanation:
To order all the numbers from least to greatest, but all the numbers in the same form (fraction, decimal, or percent). I will put them all in decimal form so that I can compare them.
0.64, .64
2/3 , =.666666repeating
65% = 65/100 = .65
7/10 = .7
.64< .65<.6666repeating<.7
but we need to put them in their original form
.64 < 65 % < 2/3 < 7/10
Answer:
x = 80°
Step-by-step explanation:
Find attached the complete question with diagram. Also find attached the diagram used for solving the question.
There area 3 angles in the diagram:
x + 8, 2x + 12, x + 20
Let the interior angles be labelled a, b, and c
a+ 2x+12 = 180° (sum of angles on a straight line)
a= 180-(2x+12) = 168 -2x in degrees
b+ x+20 = 180° (sum of angles on a straight line)
b = 180-(x+20) = 160 -x in degrees
c+ x+8 = 180° (sum of angles on a straight line)
c = 180-(x+8) = 172-x in degrees
a+b+c = 180° (sum of angles in triangle)
(168 -2x)° + (160 -x)° + (172-x)° = 180°
500 -4x = 180
500-180 = 4x
320 = 4x
x = 320/4
x = 80°
