Multiply everything by 2 then combine like terms
Answer:
6 weeks
Step-by-step explanation:
Given that :
Nikki :
Initial amount = $1100 ;
Amount spent per week = $35
Mich:
Initial amount = $520
Amount saved per week = $55
Number of weeks they'll both have the same amount :
Let number of weeks = w
For Nikki who is spending :
1100 - 35w - - - (1)
For Mich who is saving :
520 + 55w - - - (2)
Equate (1) and (2)
1100 - 35w = 520 + 55w
1100 - 520 = 55w + 35w
580 = 90w
w = 580 / 90
w = 6.444
About 6 weeks
Answer:
B) 120
Step-by-step explanation:
m = miles
$98=$80+$0.15m
$98-$80=$80-$80+$0.15m
$18=$0.15m
$18/$0.15=$0.15m/$0.15
120=m
Juliet drove 120 miles for $98.
(this is a good explanation, I guess)
Answer:
Scale using for plan ⇒ 1 m = 4 cm
Step-by-step explanation:
Given:
Actual length of wall = 4 m
Segment of wall = 16 cm long
Find:
Scale using for plan
Computation:
Actual length of wall = Segment of wall
4 m = 16 cm
1 m = 16 / 4 cm
1 m = 4 cm
Scale using for plan ⇒ 1 m = 4 cm
