Answer:
1/5x - 12 = -7
Step-by-step explanation:
The first thing says 12 less THAN. Normally, when you see something in word problems like "less than" it means you need to switch the places.
So rather than 12 - 1/5, it's 1/5 - 12.
1/5 of a number means you are multiplying that number by 1/5. we'll use x (or any letter really, doesn't matter) to represent the unknown number.
Remember that if a variable and number is written together, it means multiplication.
So, 1/5x - 12 = -7.
The answer would be 3,712.5 feet im prettyyyy sure
Answer:
Expression for perimeter of triangle = 5x+8
Step-by-step explanation:
Given that:
Length of bottom of triangle = b = x
Length of other side = a = 3x + 5
Length of last side = c = x + 3
Perimeter of triangle = a + b + c
Perimeter = (3x+5)+x+(x+3)
Perimeter = 3x+5+x+x+3
Perimeter = 5x + 8
Hence,
Expression for perimeter of triangle = 5x+8
