Answer: x= 5-y/2
y= 5-2x
Step-by-step explanation:
2x + y= 5
4x + 2y=10
Addition of the two equations gives:
6x + 3y = 15
6x= 15- 3y
x= 15-3y/6 or simplified to x = 5-y/2
3y= 15- 6x
y= 15-6×/3 or simplified to y= 5-2x
It would be 12 bags
Explanation:
24+3c=5c
24=2c
c=12
Answer:
replicating
Step-by-step explanation:
Answer:
x = 40 1/2
Step-by-step explanation:
The hash marks tell you the triangles are similar and the smaller one is 1/2 the size of the larger one. Then x is half the length of the corresponding segment marked 81.
x = 81/2
x = 40 1/2
___
You may have to write it as 81/2 or as 40.5. Sometimes the answer needs to be in a particular form.
Answer:
The value under the radical is 3
Step-by-step explanation:
9^(2/3) This means 9 squared then find find the cube root of the answer.
9^(2/3)=∛(9^2 )
= ∛81
= ∛(3×3×3×3) = ∛(3)³ ₓ ∛3
= 3∛3
The value under the radical is 3
I hope this now shows clearly the number under the radical is 3.
