13/1 because we can divide both sides by 5 and we’ll get 13/1
Answer:
1. Add 6 to both sides, cause that is the inverse of subtraction, so you get 5x = 50 as 6 cancels 6 out.
2. Divide 5 from both sides and get x = 10
Answer:
The values of x and y to the given equations are x=-1 and 
The solution is (-1,
)
Step-by-step explanation:
Given equations are 
and 
to solve the given equations by elimination method :
Adding the given two equations (1) and (2) we get


_______________
4x=-4

Therefore x=-1
Now substitute the value x=-1 in equation(1) we get
(-1)+3y=9
3y=9+1

Therefore the values of x and y to the given equations are x=-1 and 
The solution is (-1,
)
I assume the denominator is (4-√3)
Multiple both top and bottom by (4+√3)
[5(4+√3)]/[(4-√3)(4+√3)]
=[20+5√3]/[4²-(√3)²]
=[20+5√3]/13
Answer:
The Question is Incomplete still What i understood I let you Explain.
x = 78°
Step-by-step explanation:
Let
m∠ A = 78°
m∠ B = 56°
m∠ C = 100°
m∠ D = (x + 48)°
Be angles of Quadrilateral.
To Find:
x = ?
Solution:
Property of a Quadrilateral sum of the measures of the angle is 360°.
∴ m∠ A + m∠ B + m∠ C + m∠ D = 360°
Substituting above given values we get
∴ 78° +56° + 100° + ( x + 48° ) = 360°
∴ x + 282° = 360°
∴ x = 360° - 282°
∴ x = 78° ........... which the required answer
