Answer:
(S - 3) + (X - 3) = B
Step-by-step explanation:
S = amount of shirts
X = amount of jeans
B = total amount she would pay
(S - 3) + (X - 3) = B
One of the properties of triangle is the opposite of the largest angle is the longest leg and the smallest angle is opposite the shortest leg.
Given the three sides of the triangle with its corresponding angle, we have:
(2m+3) = m∠X
(m-3) = m∠Y
(m+8) = m∠Z
assign value for m; let m = 6
2(6)+3 = 15 = m∠X
6 - 3 = 3 = m∠Y
6 + 8 = 14 = m∠Z
As the sides correspond to its angle, therefore, the largest angle is m∠X and the smallest is m∠Y
The correct one is m∠Y < m∠Z < m∠X
Answer:
x = 2
Step-by-step explanation:
Given the 2 equations
2x + y = 3 → (1)
5x - 2y = 12 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the y- term
4x + 2y = 6 → (3)
Add (2) and (3) term by term
(5x + 4x ) +( - 2y + 2y) = 12 + 6 , that is
9x = 18 ( divide both sides by 9 )
x = 2
Answer: -180
work: 0-60-60-60
To solve this problem, you set up the equation 45+(2x-5)=180
Next, subtract 45 from 180 to get the equation 2x-5=135
After that, add 5 to 135 to get 2x=140
Diviode 140 by 2 to get X=70
