- Terms/Coefficients
- Coordinates (x, y)
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
-4x = y - 42
x = 18 + y
<u>Step 2: Solve for </u><em><u>y</u></em>
- Substitute in <em>x</em>: -4(18 + y) = y - 42
- Distribute -4: -72 - 4y = y - 42
- [Addition Property of Equality] Add 4y on both sides: -72 = 5y - 42
- [Addition Property of Equality] Add 42 on both sides: -30 = 5y
- [Division Property of Equality] Divide 5 on both sides: -6 = y
- Rewrite/Rearrange: y = -6
<u>Step 3: Solve for </u><em><u>x</u></em>
- Define original equation: x = 18 + y
- Substitute in <em>y</em>: x = 18 - 6
- Subtract: x = 12
Answer: 600 members of the club
Step-by-step explanation:
- In a statistical study , a population is a large group of observations by the researcher's point of view regarding the objective of the study.
A sample is a subset of the population that represents the entire population.
Here , we are given that ,
The club surveys 50 of its 600 members.
Clearly , Population = 600 members of the club
Sample = 50 members
Hence, the population of this study is "600 members of the club " .
Answer:
728 m^2
Step-by-step explanation:
There are 5 faces of the square pyramid.
You have to calculate area of each face and add them to find surface area.
Bottom face is a square, so
area = 14^2 = 196 m^2
All the other faces are triangle with same area, so
4 × triangle area
4 × ((1/2)×14×19)
4 × 133
532 m^2
Now add those areas,
(196 + 532) m^2
728 m^2

▹ Answer
<em>X = 24</em>
<em>m = 13/7 or about 1.86</em>
▹ Step-by-Step Explanation
X/3 + 7 = 15
X + 3 * 7/3 = 15
X + 21/3 = 15
X = 24
3.5m - 1.5 = 5
35/10m - 15/10 = 5
5 * 7/2 * 5m - 3 * 5/2 * 5 = 5
m = 13/7 or about 1.86
Hope this helps!
