Step-by-step explanation:
425 - 125 (what shes already saved)
300 divided by 20 (amount shes saving each week)
Result is 15, so 15 more weeks.
Hope this helped :)
If you mean how many weeks total, 125 according to the 20 dollars a week would bring it 22 weeks i think.. since the answer answer is 21.2 weeks exactly when you divide 425 by 20.
If we have a triangle with sides a,b,c then
b-a < c < b+a
describes the restriction of the length of side c, given sides a and b. This is due to the triangle inequality theorem.
a = 6
b = 9
b-a < c < b+a
9-6 < c < 9+6
3 < c < 15
<h3>Answer: The third side is between 3 cm and 15 cm. The third side cannot equal 3 cm, and it also cannot equal 15 cm. </h3>
Nora's speed (5*8)m²/2h= 20 m²/h.
Zack's speed (4*9)m²/3h= 12 m²/h
Together for 1 h they paint (20+12) m²/h=32m²/h
Given area (10*12)m²=120 m²
120m² *1h/32m² = 3.75 h (3h 45 min) to paint 10m*12m together.
