X = larger number, y = smaller number
x + y = 38...because the sum of the numbers is 38
x = 2y - 10....larger one is 10 less then twice the smaller
now we will sub in 2y - 10 for x back into the first equation
x + y = 38
2y - 10 + y = 38
3y - 10 = 38...add 10 to both sides
3y = 38 + 10
3y = 48 ...divide both sides by 3
y = 48/3
y = 16
now sub 16 in for y back into either of the original equations and find x
x = 2y - 10
x = 2(16) - 10
x = 32 - 10
x = 22
so ur numbers are 16 and 22

Answer:
B
Step-by-step explanation:
We require 2 equations in 2 variables
let x be the number of salads sold and y the number of drinks sold, then the 2 equations are
x + y = 209 → (1)
6.5x + 2y = 836.5 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate y
- 2x - 2y = - 418 → (3)
Add (2) and (3) term by term
(6.5x - 2x) + (2y - 2y) = (836.5 - 418) ← simplify
4.5x = 418.5 ( divide both sides by 4.5 )
x = 93
The number of salads sold was 93
Answer:
Your answer for both is 31 degrees
Step-by-step explanation:
Because they are similar we know their angles are the same. If you know the rule about triangles' interior angles always add up to 180, then you can just easily find this out.
First you do
82+67 = 149
Take that answer and minus it by 180
180-149 = 31
