Find the width of a rectangle with a perimeter of 90 and a length of 15
A. 90
B. 15
C. 45***
D. 30
I hope you weren't just guessing.
1.
3p + 3q = p
2p = -3q
p = -3q/2
The way you typed the answers, none are valid
2.
d = rt
d/t = r , all you have to do is divide both sides by t
3.
2L + 2W = P
30 + 2W = 90
2W = 60
W = 30
0 for 3 , looks like somebody has some work ahead
so what are the answers
To solve for p in the equation 3(p + q) = p, we'll follow these steps:
Step 1: Distribute the 3 to both p and q, to get 3p + 3q = p.
Step 2: Group like terms, which means subtracting p from both sides of the equation, giving us 3p - p + 3q = 0.
Step 3: Combine like terms, simplifying the equation to 2p + 3q = 0.
Step 4: Isolate p by subtracting 3q from both sides, resulting in 2p = -3q.
Step 5: Finally, divide both sides by 2, giving us p = -3/2q.
Therefore, the correct answer is D. p = -3/2 = q.
To solve for r in the equation d = rt, we'll use the following steps:
Step 1: Divide both sides of the equation by t to get r = d/t.
Hence, the correct answer is B. r = t/d.
To find the width of a rectangle with a perimeter of 90 and a length of 15, we'll use the following steps:
Step 1: The formula for the perimeter of a rectangle is P = 2(l + w), where P represents the perimeter, l represents the length, and w represents the width.
Step 2: Plug in the given values into the formula: 90 = 2(15 + w).
Step 3: Simplify the equation: 90 = 30 + 2w.
Step 4: Isolate the variable by subtracting 30 from both sides of the equation: 60 = 2w.
Step 5: Divide both sides of the equation by 2 to solve for the width: w = 30.
Therefore, the correct answer is D. 30.
