Answer:
x = 5.5
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.



-7 -7

Divide both sides by -1.

Answer:
y - 5 = 3(x - 4)
General Formulas and Concepts:
<u>Algebra I</u>
Point-Slope Form: y - y₁ = m(x - x₁)
Step-by-step explanation:
<u>Step 1: Define</u>
Slope <em>m</em> = 3
Point (4, 5)
<u>Step 2: Write equation</u>
Point-Slope Form: y - 5 = 3(x - 4)
g - 3/7 = 2/7 is an equation.

Answer:
1/4
2 x 1/8 is also 1/8 + 1/8 and that is then 2/8 and after that when you simplify you get 1/4.
Answer:
Step-by-step explanation:
a|c means that c=a*k k is some positive integer. We know that b|c so b| ak and (a,b)=1, so it must be b|k, i.e k=b*r, r is some positive integer number. Now we have that c=abr, so ab| c.
B) if x and x’ are both solution then we have that
mi | x-x’ for every i.
By a) we have that m1m2...mk| x-x’, so x and x’ are equal by mod od m1m2...mk.
