X,y - two numbers (x > y)
(1) x + y = 67 ⇒ x = 67 - y
(2) x - 4 = 2y
subtitute (1) to (2)
67 - y - 4 = 2y
63 - y = 2y |add y to both sides
63 = 3y |divide both sides by 3
y = 21
subtitute the value of y to (1)
x = 67 - 21 = 46
Answer: 21 and 46.
4^2+4×11
16+44
60 is the answer to the question
1) area of a cicular pool
area of a circle=πr^2 d=2.5 then r=2.5/2
A=3.14 *(2.5/2)^2
A=4.906m^2 A=4.9m^2
2) arae of a coin
<span>(if i read it right d=15mm?)
</span>A=πr^2 d=15 then r=15/2
A=3.14*(15/2)^2 =176.6mm^2
Rest all are same problems u try to solve it
Answer: i dont see the answer listed. The answer is 29 ²/₃m
Step-by-step explanation:
89m long piece of rubber is cut into 3 pieces. In other words, divided into 3 pieces.
89m ÷ 3 = 29.66666666m
Which concerts to 29²/₃m
Answer:
Equation = X*(2/3) = 3/20
Solve for X = 0.23
Step-by-step explanation:
Let, the number be "X"
According to the question,
X*(2/3) = 3/20..........(i)
From equation (i), we can get,
X = (3/20)/(2/3)
or, X = 0.15/0.66
or, X = 0.23
Alternative way,
Let, the number be "X"
According to the question,
X*(2/3) = 3/20..........(i)
From equation (i), we can get,
X = (3/20)/(2/3)
or, X = (3/20)*(3/2)
or, X = 9/40
or, X = 0.23
