Answer:
The value of y by itself in the equation x+2y=10 is
![y=\frac{10-x}{2}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B10-x%7D%7B2%7D)
Step-by-step explanation:
Given equation is x+2y=10 -------- (1)
To find y with given equation as below :
Equation (1) implies that x+2y=10
Subtracting the above equation by x we get
x+2y-x=10-x
x-x+2y=10-x
2y=10-x
Dividing by 2 on both sides we get
![\frac{2y}{2}=\frac{10-x}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2y%7D%7B2%7D%3D%5Cfrac%7B10-x%7D%7B2%7D)
![y=\frac{10-x}{2}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B10-x%7D%7B2%7D)
Therefore the value of y is ![\frac{10-x}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B10-x%7D%7B2%7D)
Therefore the value of y by itself in the equation x+2y=10 is
![y=\frac{10-x}{2}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B10-x%7D%7B2%7D)
Count the boxes each as 1.
Its easier to calculate on y axis.

Answer:
94cm
Step-by-step explanation:
wingspan length
60 meters 70.5 m
----------------- = ----------------
80 cm x
Cross multiply
(60 m)x = (70.5 m)(80 cm)
Solve for x by dividing both sides of equation by 60 m:
x = (70.5 m)(80 cm) / (60 m) = 94 cm
The length of the model is 94 cm.
Answer:
$3.53
Step-by-step explanation:
hot dogs = $1.25 each
2 hot dogs = 1.25 × 2
= $2.50
A serving of onion rings = $2.99
Drink = $0.98
Total amount with Karen = $10.00
how much change will Karen receive?
Total cost = 2 hot dogs + A serving of onion rings + Drink
= $2.50 + $2.99 + $0.98
= $6.47
Karen's change = Total amount with Karen - Total cost
= $10.00 - $6.47
= $3.53
