3 1/2 = 3.5
3.5 / 28 = 1 / x......3.5 miles to 28 minutes = 1 mile to x minutes
cross multiply
(3.5)(x) = (28)(1)
3.5x = 28
x = 28 / 3.5
x = 8 minutes <===
They are the same distance from 0
Step 1. Add 72 to both sides
5y = 7 + 5x + 72
Step 2. Simplify 7 + 5x + 72 to 5x + 79
5y = 5x + 79
Step 3. Divide both sides by 5
y = 5x + 79/5
Answer:
100deg
Step-by-step explanation:
you can use this rule: Vertically opposite angles
OR
since all angles in a line are supplementary, the angle beside the 100deg is 80deg (180-100) and so u take 180-100 again to get the ? deg

Answer:
(a) -23
Step-by-step explanation:
The sequence is arithmetic with first term 3 and common difference -2. Then the general term is ...
an = a1 +d(n -1)
an = 3 -2(n -1)
and the 14th term is ...
a14 = 3 -2(14 -1) = 3 -2(13) = 3 -26
a14 = -23
