3 (y - 0.5) = 2 (y + 1) + 4.5 Distribute the 3 into (y + 0.5)

3y - 1.5 = 2 (y + 1) + 4.5 Distribute the 2 into (y + 1)

3y - 1.5 = 2y + 2 + 4.5 Combine like terms (2 and 4.5)

3y - 1.5 = 2y + 6.5 Add 1.5 to both sides

3y = 2y + 8 Subtract 2y from both sides

y = 8

The sum of the first three terms of A.P is 18 if the first term is 4 find their product

Nataly_w [17]

Answer:

192

Step-by-step explanation:

The sum of the first 3 terms of the A. P is

a + a + d + a + 2d = 18, that is

3a + 3d = 18 ← substitute a = 4

12 + 3d = 18 ( subtract 12 from both sides )

3d = 6 ( divide both sides by 3 )

d = 2

Thus the first 3 terms are

4, 6, 8 and their product = 4 × 6 × 8 = 192

The value pi/24 is a solution for the equation 4 cos^4 (4x)-3

MatroZZZ [7]

Answer:

False

Step-by-step explanation:

4 cos^4 (4x)-3 = 0

Substitute into the equation

4 cos^4 (4pi/24)-3 = 0

4 cos^4 (pi/6)-3 = 0

Take the cos pi/6

4 ( sqrt(3)/2) ^4 -3 =0

Take it to the 4th power

4 ( 9/16) -3 =0

9/4 -3 =0

9/4 - 12/4 = 0

-3/4 =0

False
