If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate.
Answer:
$192.95
Step-by-step explanation:
$35 x 4 pants = $140
$14.50 x 6 shirts = $87
140 + 87 = $227
227(15%) = $34.05
227 - 34.05 = $192.95
The expression in standard form is n⁶ + 7mn⁵ + 14m²n⁴ - 5m³n³ - 6m⁶
<h3>How to express in standard form?</h3>
The expression is given as:
8mn⁵-2m⁶+5m²n⁴-m³n³+n⁶-4m⁶+9m²n⁴-mn⁵-4m³n³
Collect the like terms
8mn⁵ -mn⁵ - 2m⁶ -4m⁶ + 5m²n⁴ +9m²n⁴+n⁶ - 4m³n³ - m³n³
Evaluate the like terms
7mn⁵ - 6m⁶ + 14m²n⁴+n⁶ - 5m³n³
Rewrite in standard form
n⁶ + 7mn⁵ + 14m²n⁴ - 5m³n³ - 6m⁶
Hence, the expression in standard form is n⁶ + 7mn⁵ + 14m²n⁴ - 5m³n³ - 6m⁶

Answer:
15. a, 16. ∠GOH = 26
Step-by-step explanation:
15. A straight angle looks as a line.
16. ∠GOI = ∠GOH + ∠HOI
47 = ∠GOH + 21
∠GOH = 47 - 21 =26
∠GOH = 26
