1/4x + 2/5x = 39 0.6x + 0.5 = 2.9
3/5x = 9
whoever can give me the answer with work will get branliest please help asap

(a)

(b)

(c)

Step-by-step explanation:

Solving (a):

Take LCM

Multiply through by 20

Solve for x

Solving (b):

This gives:

Solve for x

Solving (c):

Multiply both sides by

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
