a rectangle has a perimeter of 76 cm. Its length is 5 more that twice its width. The system of equation below can be use to fine
Juliette [100K]

Answer:

l=27cm and w=11cm

Step-by-step explanation:

the perimeter of a rectangle is given by the following equation:

p=2(l+w)=2l+2w

if a rectangle has a perimeter of 76cm and its length  is 5 plus the double of its width we can use a system of equations to find the length l, and the width w.

For the perimeter of the rectangle

2l+2w=76 where l is its length, and  w is its width, 76 is the perimeter of the rectangle in cm.

We know that the lengh of the rectangle is 5 plus the double of its width, writing the equation:

l=5+2w

Substituting the equation above in 2l+2w=76

2(5+2w)+2w=76\\10+4w+2w=76\\6w=76-10\\w=66/6\\w=11

We got that the rectangle width is w=11cm

Substituting w in the equation 2l+2w=76

2l+2(11)=76\\2l+22=76\\l=(76-22)/2=54/2\\l=27

We got that the rectangle length is l=27cm

Verifying the values ​​obtained

2l+2w=76 with l=27 and w=11

2(27)+2(11)=76

54+22=76

Satisfying the equation

melamori03 [73]
You want 3/8 to equal 12/20. You can multiply the 3 by 4. That gets you 12 cherry halves. In order to keep the fractions the same you must also multiply the 8 by 4. Now you have. 12/32

32-20 = 12. So you have to add you need to add 12 white grapes
