Answer:
<h3>
f(2) = 7</h3>
Step-by-step explanation:
f(x) = 3x + 1 ⇒ f(2) = 3×2 + 1 = 6 + 1 = 7
Answer:
Biggest number = 13
Smallest number = 12
Step-by-step explanation:
x + y = 25... eqn 1
x - y = 1.... eqn 2
subtract equation 2 from 1
x + y = 25
-x - y = 1
---------------
2y = 24
divide both sides by 2
y = 24/2
y = 12
substitute y=12 into equation 2
x - 12 = 1
x = 12+1
x = 13
Answer:
The smallest angle is the angle shown by 3x - 17 which ends up being 49°.
Step-by-step explanation:
The angles of a triangle add up to 180 degrees. We can write an equation and solve for x.
75 + (2x + 12) + (3x - 17) = 180
~Combine like terms
70 + 5x = 180
~Subtract 70 to both sides
5x = 110
~Divide 5 to both sides
x = 22
Using what we found for x, solve for the missing angles.
2x + 12
2(22) + 12
44 + 12
66
3x - 17
3(22) - 17
66 - 17
49
Best of Luck!
Answer:
m< s = 43
Step-by-step explanation:
77 + 2x + 3 = 6x (collect like terms)
80 + 2x = 6x (subtract 2x on both sides)
80 = 4x (divide both sides by 4)
20 = x
PLUG IN TO M<S
2(20) + 3
40 + 3
m<s = 43
Hope this helps ya! Keep smiling!
