Answer:
Option B. n
Step-by-step explanation:
we know that
A regular polygon is a convex polygon whose angles are all congruent.The number of lines of symmetry in a regular polygon is equal to the number of sides a regular polygon has.
therefore
the answer is option B. n
Answer:
A.) 20h + 8
Step-by-step explanation:
The answer is 113 degrees because it’s supplementary you know you have to subtract it from 180 so 180-67=113
Answer:
- Sequon has more money after 4 weeks.
- It would take 5 weeks for their savings accounts to be equal.
Step-by-step explanation:
Daniel
Daniel starts with $50 and each week he adds $8. To find out the amount he has in any given week, the following formula would work:
= 50 + 8x
The x is the number of weeks and is multiplied by 8 because the amount of money he has increase by 8 every week.
After 4 weeks he would have:
= 50 + (8 * 4)
= 50 + 32
= $82
Saquon
Applying the same formula:
= 65 + 5x
After 4 weeks:
= 65 + (5 * 4)
= 65 + 20
= $85
Saquon has more money after 4 weeks.
<u>Number of weeks it would take for both of them to have the same amount.</u>
To find this out, equate both formulas and solve for x.
50 + 8x = 65 + 5x
8x - 5x = 65 - 50
3x = 15
x = 15/3
x = 5 weeks
<em>At 5 weeks they will both have:</em>
<em>50 + 8 * 5 = $90</em>
<em>65 + 5 * 5 = $90</em>
(j/2) + 7 = -12 // Given
(j/2) + 7 - 7 = -12 - 7 // Subtraction Property of Equality
(j/2) = -19 // Simplify
(j/2) • 2 = -19 • 2 // Multiplication Property of Addition
j = 38
