Answer:
the answer is 16
Step-by-step explanation:
Let Ted be x.
Ed is 7 years older = x + 7
Ed = (3/4)Ted
(x + 7) = (3/4)x
x + 7 = 3x/4
x - 3x/4 = -7
x/4 = -7
x = -28, Ted = -28 years
(x + 7) = -28 + 7 = -21, Ed = -21 years.
Goodness. We had negative numbers for the ages, well does that make sense? No it doesn't.
Our answer is correct. But the sense in the question is lacking. The question has been wrongly set.
We might assume negative ages to mean before they came into the world, before birth!
I believe the equation shown above is an example of:
B. Associative Property of Addition.

The measure of the seventh <em>interior</em> angle of the heptagon is 124°. (Correct choice: C)
<h3>What is the measure of the missing interior angle in a heptagon?</h3>
Heptagons are polygons with seven sides, seven vertices, seven <em>interior</em> angles and seven <em>central</em> angles. Herein we know the value of the sum of six interior angles and we need to know the measure of the seventh <em>interior</em> angle. We can determine the measure of the seven interior angles by using the following expression:
θ = (n - 2) · 180°, where n is the number of sides of the polygon. (1)
If we know that n = 7, then sum of the internal angles in the heptagon is:
θ = (7 - 2) · 180°
θ = 900°
And the measure of the final interior angle is found by subtraction:
θ₇ = 900° - 776°
θ₇ = 124°
The measure of the seventh <em>interior</em> angle of the heptagon is 124°. (Correct choice: C)
