Answer: The plumber worked 3.42 hours

Step-by-step explanation:

25h+50=135.50 (minus 50 to both sides)

25h=85.50 (divide 25 to both sides)

h=3.42

Check:

25(3.42)+50=135.50

85.50+50=135.50

135.50=135.50

Answer:

Looking at the question and goin step by step

we get to know that equation formed wud be ->

product of nine and a number - 9*x = 9x

added to 6 => 9x+6

gives us 24

so

9x + 6 = 24

now 9x = 18 and x = 18/9 = 2

and now keeping x value = 9 *(2)+6 we get 18+6 = 24

so lhs = rhs = 24

9x+6=24 option a

mixer [17]

Answer:

226

Step-by-step explanation:

Area of rectangle:

x+6=17

x=11

11+6=17

11+3=14

17×14=238

Area of triangle:

\frac{1}{2}  \times b \times h

Use phytagoras theorem to find the base of the triangle:

c²=a²+b²

5²=4²+b²

25=16+b²

b²=25-16

b²=9

b=√9

b=3 (only the half)

b=6 (the whole base)

\frac{1}{2}  \times 6 \times 4

3×4

12

Shades region:

238-12
