40/x=100/190 40/x=100/190
(40/x)*x=(100/190)*x
40=0.526315789474*x
(0.56315789474) to get x
40/0.536315789474=x
76=x
x=76 now we have 190% of 76
By converse of isosceles triangle theorem, 5x+5=7x-1
5x+5=7x-1
-5x+5x+5=7x-5x-1
5=2x-1
5+1=2x-1+1
6=2x
6/2=2/2x
X=3
AC=6x+7 when x=3
6x+7=6 (3)+7=18+7=25
AC=25
The slope can be calculated with the following formula:
In this case, you have the following points:
Answer:
3 and -4
Step-by-step explanation:
this is simple but difficult
let the number be x and second number be y
3x + 2y=1
x-y/2=5
from the 2nd equation
x-y/2=5
x=5+y/2
substitute value for x into equation 1
3x + 2y=1
3(5+y/2) + 2y= 1
15 +3y/2 +2y=1
15 + 7y/2=1
7y/2= 1 - 15
7y/2=-14
cross multiply
7y= -28
y= -28/7
y= -4
therefore second number is -4
substitute value for y into 1st equation
3x + 2y=1
3x + 2(-4) = 1
3x - 8= 1
3x= 1+8
3x= 9
x= 9/3
x= 3
therefore first number is 3
therefore two numbers are;
3 and -4
Answer:
2:34
Step-by-step explanation:
24 hours time format will only change 1 pm-12 am, those will change to 13-24 so 2:34 am is just 2:34
