Answer:
171.85 cm
Step-by-step explanation:
Given data
We are given that the distance = 149 cm 415in
Let us mark the units uniform by converting inches to cm
1 inches = 2.54cm
415 inches= x cm
cross multiply
x= 415*2.54
x= 1054.1 cm
Hence the total distance in cm is 1054.1+149= 1203cm
If in 7 days he travels 1203cm
in 1 day he will travel x cm
cross multiply
7x= 1203
divide both sides by 7
x= 1203/7
x= 171.85 cm
12=2.55 how about 8
8 x 2.55 divided by 12=$1.7
Answer:
C) x ≥ 11 or x ≤ -3
Explanation:
Given following: |x − 4| ≥ 7
Apply absolute rule: If |u| ≥ 0 then u ≤ -a, u ≥ a
Solving stepwise:
⇒ x - 4 ≤ -7, x - 4 ≥ 7
<u>change sides</u>
⇒ x ≤ -7 + 4, x ≥ 7 + 4
<u>add/subtract integers</u>
⇒ x ≤ -3, x ≥ 11
Answer:
Step-by-step explanation:
x^2 + 7x + 5x + 35
7x : II
5x: III
35: IV
