Answer:
$25.25-lasagna, $12.25-garlic bread
Step-by-step explanation:
5L+3G=163
- 4L+4G=150
______________
4(5L+3G=163)
-5(4L+4G=150)
_____________
20L+12G=652
-20L-20G=-750
_____________
-8G=-98
-8G/-8 = -98/-8
G=$12.25
now plug that into G in any of the 2 equations at the top and you can solve for L(price of lasagna)
You combine like terms like 8y+13y which gives you 21y and don't forget the -5x so your simplified equation would end up being A. 21 - 5x
This equals 365 i know that is not what you ask but this is what i know
An = a1 + (n - 1)(d)
Where a1 is the first term and d is the common difference.
First find d, the common difference.
24, ____, 32
a3 a4 a5
Subtract 32-24 = 8
Subtract a5 - a3 = 2
Divide 8/2 = 4
d = 4
Use d and one of the values they give us to find a1.
a3 = 24
24 = a1 + (3 - 1)(4)
24 = a1 + 2(4)
24 = a1 + 8
Subtract 8 from both sides
16 = a1
an = 16 + (n - 1)(4)
Can also be written
an = 16 + 4n - 4
an = 4n + 12
