<span>P = 3r + 2s
2s = P - 3r
s = (P - 3r)/ 2
s = P/2 - 3/2(r)
hope it help</span>
Answer:
8meters
Step-by-step explanation:
Perimeter of the square ribbon = 4L
L is the side length of the table
Given
L = 2 meters
Substitute
Perimeter of the square ribbon = 4(2)
Perimeter of the square ribbon = 8meters
Hence she will need 8meters of ribbon to decorate the square
Answer:
Treat the lesser than sign as an equal sign. What you do to one side, you do to the other. Isolate the variable x. Do the opposite of PEMDAS.
PEMDAS = Parenthesis, Exponents ( & roots), Multiplication, Division, Addition, Subtraction.
<u>Solve -6x + 14 < -28</u>
First, subtract 14 from both sides:
-6x + 14 (-14) < -28 (-14)
-6x < -42
Next, divide -6 from both sides to isolate the variable x. Note that when you divide (or multiply) by a negative number, you must flip the greater than or less than sign.
(-6x)/-6 < (-42)/-6
x > (-42)/(-6)
x > 7
x > 7 is your answer.
<u>Solve 3x + 28 < 25</u>
First, subtract 28 from both sides.
3x + 28 (-28) < 25 (-28)
3x < -3
Isolate the variable x. Divide 3 from both sides. Note that because you aren't dividing by a negative number (rather a positive 3), you do not flip the sign.
(3x)/3 < (-3)/3
x < (-3)/(3)
x < -1
x < -1 is your answer.

Answer:
The answer is 1 3/5
Step-by-step explanation:
- 2÷5 = 0.4
- 0.4×4 = 1.6
- 1.6 = 1 3/5
Answer:
C(m) = $(40+3m)
Step-by-step explanation:
In this question, we are asked to write an equation representing the total cost of renting a truck by Makayla.
We proceed as follows;
Form the question, we can deduce that there is an initial cost of $40 and a rental fee of $3 per mile driven.
Now, we were made to know that she had driven m miles. We now calculate the rental fee for this m miles she has driven. Mathematically, we only need to find the product here. The rental fees for the m Miles traveled would be m * 3 = $3m
Now the total cost C(m) would be = $40 + $3m or simply C(m) = $(40+3m)
