Question

1. Form a linear equation from the given statement: When 5 is added to twice a number.it
gives 11.
2. Verify that x = 2 is the solution of the equation 4.4x -3.8 = 5.
3. The angles of a triangle are in the ratio 2:3:4. Find the angles of the triangle.
4. The sum of two numbers is 11 and their difference is 5. Find the numbers.
5. If the sum of two consecutive numbers is 11. find the numbers.​

Answer 1

Answer:

I don't know the answer sorry

Answer 2

Step-by-step explanation:

• 1》5+2x=1
• 2》4.4x-3.8=5
• 4.4x=5+3.8
• 4.4x=8.8
• x=8.8/4.4=2
• so hence verified
• 3》let the angels =2x,3xand4x
• so sum of all the angles of triangle =180°
• do 2x+3x+4x=180
• 9x=180
• x=180/9=20
• 2x=40,3x=60,4x=80
