F + 0.3 < 1.7 Graph the solution on a number line
2 answers:
So,
F + 0.3 < 1.7
Subtract 0.3 from both sides.
F < 1.4
S = {F | F < 1.4}
Attached please find a number line with the solution.
F + 0.3 < 1.7
Subtract 0.3 from both sides.
F < 1.4
S = {F | F < 1.4}
Attached please find a number line with the solution.
So we can do anything to the equation as long as we do it to both sides
f+0.3<1.7
subtract 0.3 from both sides
f+0.3-0.3<1.7-0.3
f+0<1.4
f<1.4
so f is less than 1.4 not including 1.4
a number line would have a dot that is NOT filled in on 1.4 and then from that dot, it would go in the negative direction forever (normally to the left)

f+0.3<1.7
subtract 0.3 from both sides
f+0.3-0.3<1.7-0.3
f+0<1.4
f<1.4
so f is less than 1.4 not including 1.4

Hi there!
We can solve for x knowing that the sum of interior angles in a triangle is 180°.
The square at the bottom indicates a right angle, or 90°. Therefore:
180 = 90 + x + (x + 10)
Combine like terms:
180 = 100 + 2x
Subtract 100 from both sides:
180 - 100 = 2x
80 = 2x
Divide both sides by 2:
x = 40.
