Answer: yes , it is possible
Step-by-step explanation:
Let the first number be x and the second number be y .Then , the sum of the two numbers will be x + y , and their difference will be x - y.
Combining the two , we have :
x + y = 1 ............................... equation 1
x - y = 8 ................................. equation 2
solving the system of linear equation by substitution method. From equation 1 , make x the subject of the formula ,
x = 1 - y ...................... equation 3
Substitute equation 3 into equation 2 ,
1 - y - y = 8
1 - 2y = 8
add 2y to both sides
1 = 8 + 2y
subtract 8 from both sides
1 - 8 = 2y
- 7 = 2y
divide through by 2
y = 
y = - 3.5
substitute y = -3.5 into equation 3 to find the value of x , we have
x = 1 - y
x = 1 - ( - 3.5 )
x = 1 + 3.5
x = 4.5
Let us check :
x + y will be
4.5 + (-3.5) = 1
Also ,
x - y will be
4.5 - (-3.5)
⇒ 4.5 + 3.5 = 8
Answer:
Step-by-step explanation:
Distance between two points 
and 
is given by the formula,
Distance = 
a). A(-6, -4), B(-3, -1)
Distance between A and B = 
= 
= 3√2
= 4.2 units
b). C(3.5, 1), D(-4, 2.5)
Distance between C and D = 
= 
= 7.65
≈ 7.7 units
c). Distance between X(5, -5) and Y(-5, 5)
Distance = 
= 
= 10√2
= 14.14
≈ 14.1 units
Answer:
-459 2/9
Step-by-step explanation:
calculate 34-99= -65
and turn 2 7/9 into a mixed number as 25/9
leaves u with
7(-65)-7+25/9
multiply 7x-65=-455
-455-7+25/9
-462+25/9
get common denomionator and add
-4133/9 or -459 2/9 or -459.2
Answer:
1/4
Step-by-step explanation:
Firstly, we need the numbers that are less than or equal to 17 minutes
These numbers from the data set are;
12 and 16
The count of numbers is;
8
so the fraction we need is simply 2/8
and that is 1/4
The two triangles are right angled Triangles and they have one common angle. so the two triangles are similar to each other.
By using similarity, ratio of their corresponding sides must be equal as well~
