If the width of a rectangle with periemter is P is 6 units what is its length
Hoochie [10]

Answer:

L = \frac{P - 12}{2}

Step-by-step explanation:

Since perimeter is 2L + 2W, and width is 6, then P = 2L + 2*6, and solving for L gives you (P - 12)/2

Hopefully this helps- let me know if you have any questions!

WLL GIVE. BRAINLIEST IF YOU ANSWER PLEASE

This would be easiest with a graphing calculator.

I recommend changing the mixed fractions to improper ones (so change 2 and 5/6 to 17/5, 1.75 to 7/4, 2 and 1/3 to 7/3, 1.1 to 11/10 and lastly 1.6 to 8/5) If you wish to change .14 to 14/100 and then reduce it to 7/50, then do so.

Your answer should be 1.21.

On a calculator, type in ((17/50+(7/4)x(7/50)). Hit enter. Then input ((7/3)x(11/10)/(8/5)). Hit enter. Then divide the top number and the bottom number.

The sum of two numbers is 2490 and if 6.5 percent of one no. is equal to 8.5 percent of the other, then numbers are ?? Make sure
lions [1.4K]

Answer:

The two number are :

x = 1411

y = 1079

Step-by-step explanation:

Let the two numbers = x and y

The sum of two numbers is 2490

x + y = 2490..... Equation 1

If 6.5 percent of one no. is equal to 8.5 percent of the other,

Hence:

6.5% of x = 8.5% of y

0.065x = 0.085y

Make x the subject of the Formula

x = 0.085y/0.065

x = 1.308y

We substitute 1.308y for x Equation 1

x + y = 2490..... Equation 1

1.308y + y = 2490

2.308y = 2490

y = 2490/2.308

y = 1078.8561525

y = 1079

x + y = 2490..... Equation 1

x = 2490 - y

x = 2490 - 1079

x = 1411
