This entire expression gives the total number of apples required to make 2 pies and 4 cakes.
x is the number of apples for a cake. 3x would be the number of apples it takes to make a pie. 2(3x) would be the apples for 2 pies and 4(x) would be the number of apples for 4 cakes.
Amy:
8 + 5 + 6 + 11 + 4 + 6 +8 = 48
48 divide by 7 = 6.85
chelsea:
7 + 9 + 5 + 3 + 10 + 5 + 8 = 47
47 divide by 7 = 6.71
amy runs more on average.

Answer:
The value of 'x' is 17.
Step-by-step explanation:
Given:
Δ IJK ≅ ΔPQR
m∠I = 3x + 4
m∠P = 72 - x
To Find:
x = ?
Solution:
Δ IJK ≅ ΔPQR ...........Given
If two triangles are congruent then the corresponding angles of congruent triangles are congruent.
∴∠ I ≅ ∠ P ........corresponding parts of congruent triangle (CPCT)
Substituting the values we get

The value of 'x' is 17.

The solution of the equations is the coordinates of the point where the two lines intersects, so the required solution is :
