X=205
y=41
You come across these answers by making an equation or system of equations based on the word problem given. 1. x+y=246 and 2. x÷y=5 . The you would multiply by y on both sides and get x=5y . Then you would substitute for x in the first equation and get (5y)+y=246 . Then you would get 6y=246 . Them you would divide by 6 on both sides and get y=246÷6 . Then you would get y=41. Then you would plug the y value into the first equation. You would get that x+(41)= 246, subtract on both sides and get x=246-41, then you would get an answer of x=205.
Answer:
y= (x+4)(x+4) is the answer
Step-by-step explanation:
Identity used= (a+b)²= a²+2ab+b²
Step-by-step explanation:
1 m = 100 cm So
48 × 100 = 4800 cm
1m = 1000mm
456 mm into m
= 456 ÷ 1000
= 0.456 m
Answer
- DE= 3x + 20 = 86
- EF= 2x + 40=84
Step-by-step explanation:
DE: 3x + 20
EF: 2x + 40
DE+ EF= DF
3x+20 +2x + 40 = 170
5x + 60 =170
5x= 110
x= 22
- DE= 3x + 20 = 86
- EF= 2x + 40=84
Okay so if
4cm:9ft
Than
8cm:18ft
2cm:4.5ft
1cm:2.25ft
Okay so
1•11=11
2.25•11=24.75
The answer is 24.75ft
