Answer:
-8±10x
Step-by-step explanation:
you will follow BODMAS
B=bracket
O= off
D=division
M=multiplication
A=addition
S=subtraction
2×3=6
7×2=14
[6-14±10x-8]÷[x-2]
14±8=22
6-22=-16
[-16±10x]÷[x-2]=-8±10x
2x + 3y = 23...........................(1)
3x - y = 7 Multiply by 3:-
9x - 3y = 21 Adding this to equation (1):-
11x = 44
x =
Plug this into equation (1):-
2(4) + 3y = 23
3y = 15
y = 5
Answer is x = 4, y = 5
Given:
Point Q is on line segment PR.
QR = 3x, PQ = x + 6, and PR = 5x – 4.
To find:
The numerical length of PQ.
Solution:
Since, point Q is on line segment PR, so by segment addition property, we get
The value of x is 10.
Now,
Putting x=10, we get
Therefore, the numerical length of PQ is 16 units.
Answer:
Scale factor can be used in almost all situations. Scale factor is used in math and can be used when constructing any mini model of a real life design. Scale factor is often utilized in cooking recipes/procedures.
