[ Explanation ]
- Factor x3 - 7 · 2 - 5x + 25 By Grouping
--------------------------------------------
- Add Similar Elements: 3x - 5x = -2x
-2x - 7 · 2x + 35
- Multiply Numbers: 7 · 2 = 14
-2x - 14x + 35
- Add Similar Elements: -2x - 14x = -16x
-16x + 35
angles in a triangle always equal to 180° so:
1. all the angles are equal to each other
180°÷3=60°
2.
•we know 1 angle, 68°
• straight lines are 180°-> 180°-126°= 54°
180°-68°-54°= 58°
Total number of times rolled = 360
Total number of 2s and 3s = 31 + 49 = 80
P(2 or 3) = 80/360 = 2/9 = 0.22 (nearest hundredth)
Answer: 0.22
Answer:
(9,3)
Step-by-step explanation:
x = 9, y = 3
<h2>
1. FIRST QUESTION.</h2>
M is directly proportional to
Suppose you have two variables, say, . We say that varies directly as or, in other words, is directly proportional to if and only if:
Where is a nonzero constant called the constant of proportionality.
Knowing this, we can solve this problem. Here is directly proportional to . So:
We know that when , hence the constant of proportionality can be found as follows:
So:
<h3>PART A)</h3>
When , then:
<h3>PART B)</h3>
When , then:
<h2>2. SECOND QUESTION.</h2>
M is directly proportional to
We know that when , hence the constant of proportionality is:
So:
<h3>PART A)</h3>
When , then:
<h3>PART B)</h3>
When , then:
