Answer:
-2 , -10 & -99
Step-by-step explanation:
1)
⇒ x + 6 = 4
⇒ x = 4-6
⇒ x = (-2)
2)
⇒x - (-4) = -6
⇒ x + 4 = -6
⇒ x = -6-4
⇒ x = -10
3)
⇒2(x-1) = -200
⇒ x - 1 = -200/2
⇒ x - 1 = -100
⇒ x = 1 - 100
⇒ x = (-99)
1.Identify the fractions. Using the distributive property, you’ll eventually turn them into integers.
2.For all fractions, find the lowest common multiple (LCM) -- the smallest number that both denominators can fit neatly into. This will allow you to add fractions.
3.Multiply every term in the equation by the LCM.
4.Isolate variables adding or subtracting like terms on both sides of the equals sign.
5.Combine like terms.
6.Solve the equation and simplify, if needed.
Answer:
$2046
Step-by-step explanation:
Add 1947 and 99 because he is depositing, as in adding, 99 dollars
b = i+12
b-3 = 4( i-3) ------> b-3=4i-12 ----->b=4i-9
b = i+12
b=4i-9
i+12=4i-9
21=3i
i=7
b= i+12
b=7+12=19 Ben is 19 years old now
Answer:
Step-by-step explanation:
m∠P + m∠Q + m∠R = 180 degree
-> m∠R = 180 - ∠P - ∠Q = 180 - 99 - 31 = 50
PQ = 
=8.53
PR = 
=5.74
