Answer:
x=-2
Step-by-step explanation:
Step 1: Subtract 8x from both sides.
5x+6−8x=8x+12−8x
−3x+6=12
Step 2: Subtract 6 from both sides.
−3x+6−6=12−6
−3x=6
Step 3: Divide both sides by -3.
−3x
−3
=
6
−3
x=−2
Answer:
Ray = 19 yrs old
Tom = 25 yrs old
John = 57 yrs old
Explanation:
Let x be the years of Tom
R = x - 6
J = 3R = 3(x - 6)
T = x
R + J + T = 101
x - 6 + 3(x - 6) + x = 101
2x - 6 + 3x - 18 = 101
5x - 24 = 101
5x = 125
x = 125/5 = 25
R = 25 - 6 = 19
J = 3(25 - 6) = 57
T = 25
Total amount of muffins: 3×6= 18 muffins.
Amount of muffins without nuts:
total amount of muffins - muffins with nuts
18-3= 15 muffins without nuts
Answer:
(-2, 4)
Step-by-step explanation:
y = -3x - 2
y = -x +2
=> -3x - 2 = -x +2
-3x + x = 2 + 2
-2x = 4
x = -2
-x + 2 = y
2 + 2 = y
4 = y
Answer:
A-14
Step-by-step explanation:
All the angles of the triangle ABC are 60°.
Therefore it is an equilateral triangle.
All sides of an equilateral triangle are equal.
Hence, AC = 14
