2x + 4 = 12
Step one: subtract 4 from both sides.
2x = 8
Step two: divide both sides by two.
x = 4
I cannot see the entire picture, but I hope this helps.
Answer:
Let 7x be the rent paid for backhoe for seven hours.
Step-by-step explanation:
Keyword: maximum amount, the most
Inequality symbol: ≤
(800 × 5) + 7x ≤ 9,000
4,000 + 7x ≤ 9,000
7x ≤ 9,000 - 4,000
7x ≤ 5,000
7x ÷ 7 ≤ 5,000 ÷ 7
x ≤ 714.29
To the nearest hundreds:
x ≤ 700
ANSWER: The maximum rental fee per hour of backhoe is Php 700.00 (rounded off to the nearest hundreds).
To check if he paid less than 9,000 for the total rent:
(800 × 5) + (700 × 7) < 9,000
4,000 + 4,900 < 9,000
8,900 < 9,000 (True)
We will use the followin property of logarithms:
So, we have
If you multiply both sides by 4, you get
Answer:
120 degrees
Step-by-step explanation:
Since the total degree measure of a circle is 360 degrees, if a part of it is 240 degrees, then the rest is 360-240=120 degrees. Hope this helps!
