Answer 1

Answer:

Solution :- x is 92 and y is 23

Step-by-step explanation:

Let them be x and y respectively

so given

\begin{gathered}x - y = 69 \\ \end{gathered}x−y=69

and

\begin{gathered} \frac{x}{y} = 4 \\ so \: x = 4y(cross \: multiplication)\end{gathered}yx=4sox=4y(crossmultiplication)

so we can write

x - y = 69x−y=69

as

\begin{gathered}4y - y = 69 \\ 3y = 69 \\ y = 69 \div 3 \\ y = 23\end{gathered}4y−y=693y=69y=69÷3y=23

now y is 23

so putting in any equation will give the value of x

so

\begin{gathered}x - y = 69 \\ = > x - 23 = 69 \\ x = 69 + 23 \\ x = 92\end{gathered}x−y=69=>x−23=69x=69+23x=92

x is 92 and y is 23

Hope it helps

Answer 2

Answer: a)92

b)20,21,22

c)3/5

d)15/22

Step-by-step explanation:

a)x-y

x/y--->x= 4y

Subtract into the first 4y-y=69

3y=69

y= 69/3

y=23

then,x=4(23)=92

b) let x,x+1 ,x+2 are three consecutive Integers

sum of three numbers=63 (given)

=>x+x+1+x+2=63

=>3x+3=63

=>3x=63-3

=>3x=60

=>x=60/3

=>x=20

Therefore,the three consecutive Integers are

X=20

X+1=20+1=21

X+2=20+2=22

c)7/11-1/3x=24/55

21-11x/33=24/55

21-11x/3=24/5

105-55x=72

-55x=72-105

-55x=-33

x=-55/-33

x=3/5

d) let the fraction be p/q

so q=p+7

p+17/q-6=2

=>p+17/p+7-6=2

=>p+17/p+1=2

=>p+17=2p+2

=>p=15

=>q=15+7=22

so,p/q=15/22
