Answer:
80 miles per hour
Step-by-step explanation:
(66✖️578) ➗ 3368=55➗77
P parentheses
E exponents
M multiplication
D division
A addition
S subtraction
You would do (66✖️578) first since it is in parentheses
66✖️578=38,148
38,138➗3368=55➗77
Since there are no exponents or multiplication you would do division
38,138➗3368= 11.3236342
55➗77=0.7
11.32 does not equal 0.7
So this equation would be false
Hope this helps! :3
Yea it’s B because I did the mathhhhhh
Answer:
The area of the rectangle is 1222 units²
Step-by-step explanation:
The formula of the perimeter of a rectangle is P = 2(L + W), where L is its length and W is its width
The formula of the area of a rectangle is A = L × W
∵ The length of a rectangle is 5 less than twice the width
- Assume that the width of the rectangle is x units and multiply
x by 2 and subtract 5 from the product to find its length
∴ W = x
∴ L = 2x - 5
- Use the formula of the perimeter above to find its perimeter
∵ P = 2(2x - 5 + x)
∴ P = 2(3x - 5)
- Multiply the bracket by 2
∴ P = 6x - 10
∵ The perimeter of the rectangle is 146 units
∴ P = 146
- Equate the two expression of P
∴ 6x - 10 = 146
- Add 10 to both sides
∴ 6x = 156
- Divide both sides by 6
∴ x = 26
Substitute the value of x in W and L expressions
∴ W = 26 units
∴ L = 2(26) - 5 = 52 - 5
∴ L = 47 units
Now use the formula of the area to find the area of the rectangle
∵ A = 47 × 26
∴ A = 1222 units²
∴ The area of the rectangle is 1222 units²
