Question

help me to solve this questions​

Answer 1

Answer:

Q.5

1)

5 more than 15 is 20

given eq is

(X/4)=20

so X =80

2)

ACC to given condition

6x-5=7

so 6x =12

and x=2

3)

Riya has X marbles

So Rohan has 12 more than Six times I've

6x+12 marbles which is 42

so 6x+12=42.

6x=30

X =5

4) let equal Base angles be X so by addition property of ttiangle.,

X+X+60=180

2X=120

and X=60.

This is a Isoceles as well as equilateral triangle

5)

by Given condition

(X+15)/6= 6.

so X+15=36 and

X = 21.

Answer 2

Step-by-step explanation:

suppose the one fourth of a no. is x/4

then 5 more than 15 =20

x/4= 20

x =20 multiply 4

its become

x = 80
