Answer:
y-1=0
Step-by-step explanation:
To rewrite the equation 5x - 8y + 3 = 5x - 7y + 2, combine like terms across the equal sign using inverse operations.
5x - 8y + 3 = 5x - 7y + 2
5x - 5x - 8y + 3 = 5x - 5x -7y + 2
-8y + 3 = -7y + 2
-y +3 = 2
-y = -1
y- 1 = 0
Hello,
To solve this, we should first write an inequality.
Since we have to pay $109.50 to rent the studio, we will start with that.
Then, we add on 15 per person. Finally, it needs to be under $319.
The inequality is:
109.5 + 15x < 318
Solve it gives:
15x < 208.5
x < 13.9
We have to invite less than 13.9 people. So they most we can invite is only 13.
I hope this helps,

Answer: (1,-6)
Step-by-step explanation:
Answer: the eastbound train had travelled 12 miles
Explanation: using Pythagoras theorem, we know that
X^2 = a^2 + b^2
Where ^ stands for raised to power.
Let
a stand for the train going towards North and
b stands for the train going towards east.
X stands for the total distance between train a and b = 20 miles.
By Pythagoras rule
X^2 = a^2 + b^2
20^2 = 16^2 + b^2
400 = 256 + b^2 so that
b^2 = 400 - 256 = 144
b = √144
b = 12 miles.
Answer:
AB = 41 cm
Step-by-step explanation:
If B is the midpoint of AC, then B splits AC into 2 equal halves: AB & BC.
Therefore, AB = ½ of AC.
Given, AC = 82 cm.
So,
AB = ½ × AC
AB = 82/2
AB = 41 cm
