Value of the expression for x = 3 1/3 is 29.
Step-by-step explanation:
- Step 1: Simplify the expression 3(2x+6)−(3x+1)
⇒ 3(2x+6)−(3x+1) = 6x + 18 - 3x + 1 = 3x + 19
- Step 2: Find the value of the expression for x=3 1/3
⇒ x = 3 1/3 = 10/3
⇒ 3x + 19 = 3 × 10/3 + 19 = 29
Answer:
84
Step-by-step explanation:
reach triangle area is 1/2bh so
1/2(6)(4) = 12
there are 4 of them so
12x 4 = 48
then the square is 6x6 = 36
add the square to the triangle totals
48+38 = 84

Define their age
---------------------------------------------------------------------------------------
Let Jim be x years old
Jim = x
Father = x + 31 ← Jim is 31 years younger than the father
Grandfather = x + 70 ← Grandfather is 70 years older than Jim
---------------------------------------------------------------------------------------
Combined age is 137, find x
---------------------------------------------------------------------------------------
x + (x + 31) + (x + 70) = 137
x + x + 31 + x + 70 = 137
3x + 101 = 137
3x = 137 - 101
3x = 36
x = 12
---------------------------------------------------------------------------------------
Find their age
---------------------------------------------------------------------------------------
Jim = x = 12
Father = x + 31
Father = 12 + 31
Father = 43
Grandfather = x + 70
Grandfather = 12 + 70
Grandfather = 82
---------------------------------------------------------------------------------------
Answer: Jim = 12 ; Father = 43 ; Grandfather = 82
