35x=245
so you would divide both sides by 35
x=7
so it would take her 7 weeks or 1 month and 3 weeks to pay her friend back
Answer:
x = 55
y = 70
Step-by-step explanation:
since it's all sides are equal its an equilateral triangle
each angle of an equilateral triangle is 60°
therefore,
y - 10 = 60 => y = 60 + 10
y = 70
x + 5 = 60 => x = 60 - 5
x = 55
Answer: exactly one solution
Explanation: Because the two lines only cross at one point and will never cross again
For this case we must represent the following expression algebraically, in addition to indicating its result:
"2 plus 9"
So, we have:

By law of the signs of the sum, we have that equal signs are added and the same sign is placed:

ANswer:
