<h2>answer:</h2>
13/8
alternative forms:
1 5/8, 1.625
<h2>step-by-step explanation: </h2>
2 1/8-1/2
multiply 2 and 8
16+1/8-1/2
add 16 to 1
17/8-1/2
least common multiple of 8 and 2 is 8. Convert 17/8=2.125 and 1/2=0.5 to fractions with denominator 8.
17/8-4/8
subtract numerators and put denominators as only one 8.
--------
13/8
--------
Perimeter=2L+2W
L=W+5, substitute in place of 2L
90=2(W+5)+2W
90=2W+10+2W
90-10=4W
80=4W
80/4=W
W=20, if width is 20 than the length is 20+5=25 cm
It would be the second one because to make a equation perpendicular, you have to flip the fraction (and if it was a whole number like 6 it would become 1/6) and then make it negative.
So your new equation would be y=-6/7x+4
Answer:
Step-by-step explanation:
Let x be the number of flowers. If Group A were to make x flowers alone, it would take them 10 hours to complete the task, then they make 
flowers in an hour. If Group B were to make x flowers alone, it would take them 15 hours to complete the task, then they make 
flowers in an hour.
The groups decided to work together. They can make 
together in an hour and it takes them 
hours. Group B took a break for 1 hour and 40 minutes (
hour), then Group B works
hours.
Thus,
Answer:
93.75 Kg
Step-by-step explanation:
Farmer spreads 25 kg fertilizer over an area of 4000 m square .
So, Over 1 m square , 
kg of fertilizer will be needed
As we know , 1 hectare = 10,000 m square.
So, 1.5 hectare equals 15,000 m square.
So, for 15,000 m square , Fertilizer needed will be equal to ×15,000 = 93.75 Kg
So, 93.75 Kg of fertilizer is needed for 1.5 ha of land.
