Answer:
10
Step by step explanation:
In general, if we have an equation that has just one variable, such as x, then "solving the equation" means finding the set of all values that can be substituted for the one variable to produce a valid equation.
Isolate "x" on one side of the algebraic equation by adding the negative number that appears on the same side of the equation as the "x." For example, in the equation "x - 5 = 12", rewrite the equation as "x = 12 + 5" and solve for "x."
x + (-6) + (-8) = -4
x + (-6 + -8) = -4
x + (-14) = -4
x + (-14 + 14) = -4 + 14
x = 10
Answer:
9
Step-by-step explanation:
To solve this just take b (in this case 6x) divide it by 2 and then square it
which means that c=9
this will factor to (x+3)²
Answer:
c = 15t
Step-by-step explanation:
Given that:
Unit cost of Ticket = $15
Total cost = unit cost * number of tickets purchased
Total cost = c
Number of tickets purchased = t
C = $15 * t
c = 15t
Answer:
width = let width be w
area = 140
length = 2w-6
Area of a rectangle = l*b
⇒ 2w-6*w=140
⇒ 
Answer:
Step-by-step explanation:
MS = RS - RM
MS = 13 in - 4 in = 9 in
By the rules of crossing chords, ...
MS × MR = PM × QM
(9 in)(4 in) = PM² . . . . . QM = PM
PM = √(36 in²) = 6 in
PQ = PM + QM = 2×PM = 12 in
