Let the total no. of 25 p coins be x
50p coins = 2x
Value of 25 p coins ( in rupees) = 0.25*x =0.25x
Value of 50p coins ( in rupees) = 0.5*2x = x
0.25x+x = 25
1.25x =25
x = 25/1.25 = 20
no. if 25p coins = 20
and 50p coins = 2*20 = 40
Answer:



Step-by-step explanation:
Use the Triangular Interior Angles Theorem to figure this out:
180° = [7x + 1]° + [6x - 6]° + 55°
180° = [−5 + 13x]° + 55°
180° = [50 + 13x]°
-50° - 50°
____________
![\frac{130°}{13} = \frac{[13x]°}{13} \\ \\ 10° = x](https://tex.z-dn.net/?f=%5Cfrac%7B130%C2%B0%7D%7B13%7D%20%3D%20%5Cfrac%7B%5B13x%5D%C2%B0%7D%7B13%7D%20%5C%5C%20%5C%5C%2010%C2%B0%20%3D%20x)
You then plug this back into all three expressions to get 71° as the measure of ∠G and 54° as the measure of ∠T.

A straight horizontal line where the y-intercept is -3
Answer:
(- 3, - 7 )
Step-by-step explanation:
Given the 2 equations
y = 4x + 5 → (1)
y = x - 4 → (2)
Substitute y = 4x + 5 into (2)
4x + 5 = x - 4 ( subtract x from both sides )
3x + 5 = - 4 ( subtract 5 from both sides )
3x = - 9 ( divide both sides by 3 )
x = - 3
Substitute x = - 3 into either of the 2 equations and evaluate for y
Substituting into (2)
y = x - 4 = - 3 - 4 = - 7
solution is (- 3, - 7 )
