1/2(4d-2)=d+5
2d-1=d+5
2d-d=5+1
d=6
Answer:
Elizabith bought 3 lbs of apples at $1.99 per lb.
This means that cost of 3 lbs of apple= $ (1.99×3)
i.e. cost of 3 lbs of apple= $ 5.97
Two loaves of bread at $.89 per loaf.
Cost of 2 loaves= $ (0.89×2)
i.e.
Cost of 2 loaves= $ 1.78
A box of cereal at $3.99 per box.
Cost of one gallon of milk at $3.19 per gallon.
This means that the total cost of his purchase is:
$ (5.97+1.78+3.99+3.19)
= $ 14.93
If Eliza paid with $20.
This means that the change she will receive is:
= $ (20-14.93)
= $ 5.07

The answer is (5, -4) or x= 5, y= -4 making this system have 1 solution.
If you can please make mine the brainliest that would be much appreciated. Thanks!
Answer:
x = 12.68
y = 9.43
Step-by-step explanation:
(refer to attached)
recall that all the internal angles within a triangle sum up to 180°, hence the missing internal angle
= 180° - 62° - 41 °
= 77°
using the law of sines (i.e sine rule)
x / sin 62° = y / sin 41° = 14 / sin 77°
we can thus solve for x and y:
Considering X,
x / sin 62° = 14 / sin 77°
x = (14 sin 62°) / (sin 77)
x = 12.68
Considering y,
y / sin 41° = 14 / sin 77°
y = (14 sin 41°) / (sin 77°)
y = 9.43
Hope this helps!
