Answer:
2 : 1
Step-by-step explanation:
27 total
9 filled
27 - 9 = 18 empty
18 : 9
2 : 1
I suppose we have to find the lengh of the sides.
Area = lenght × width
288 = (3x) × (2x+10)
288 = 3x (2x+10)
288 = 6x + 30x
288 = 36x
288/36 = x
8 = x
therefore the sides are
3x = 3×8 = 24 inches
2x+10 = 2×8 + 10 = 16 +10 = 26 inches
Y= 58x + 55
They charge 58$ per hour therefore 58 should correlate with x and since when don’t know y (the total amount) its y= and then just add 55
- 4/5 (9x-20)-3x=4/5x-6
Solution: x = 2
Answer:
Number of boys = 6
Step-by-step explanation:
It is given that:
Number of girls in school club = 16
Let,
b be the number of boys.
g be the number of girls.
g = 2b + 4
Putting g=16
16 = 2b + 4
16 - 4 = 2b
2b = 12
Dividing both sides by 2
Therefore,
Number of boys = 6
