Answer:12

Step-by-step explanation:

Perimeter of a square =4L

Perimeter of larger square is twice the perimeter of square =2x4L=8L

Wire length =18ft

Wire length =sum of the two perimeterr

18=4L+8L

18=12L

L=18/12

L=1.5

Perimeter of larger square=8L

Replace Lwith 5

Perimeter of larger square =8x1.5

Perimeter of larger square =12ft

Answer:

12

Step-by-step explanation:

18/3=6

If one piece is twice as large as the other, than 18 needs to be divided by 3, making it exact.

PLS ANSWER THESE QUESTIONS. I WILL GIVE 20 POINTS AD BRAINLIEST.
erastova [34]

Answer:

1. 3x + 6

2. \frac{99}{14} or 7.071

3. -\frac{1}{2}

Step-by-step explanation:

1. 3 consecutive even integers

If the first is x, the 2nd is x+2, and the 3rd is x+4

x + (x+2) + (x+4)

= 3x + 6

2. The equation for circumference is

C=2\pi r

If the diameter is 1\frac{4}{5} = \frac{9}{5}

The the radius is half of that.

So the circumference is

\pi * \frac{9}{4} *\frac{1}{2} * 2\\= \pi * \frac{9}{4}\\=\frac{22}{7} * \frac{9}{4}\\= \frac{198}{28}\\ =\frac{99}{14} \\=7.071

3. To divide we multiply by the reciprocal.  So flip the fraction that we are dividing by.

\frac{1}{7} / -\frac{2}{7}\\ = \frac{1}{7} * -\frac{7}{2} \\= -\frac{1}{2}

Ellen went to the store and bought 4 oranges and 5 apples for $4.00. Jessie bought 2 oranges and 3 apples for $2.20. How much is
Anastasy [175]

Answer:

1 apple= $0.4

Step-by-step explanation:

Let o=orange

Let a=apple

4o+5a=4

2o+3a=2.20

2o=2.20-3a

o=2.20-3a/2

Let's go balk to the the first equation

4o+5a=4

4(2.20-3a/2)+5a=4

4.4-6a+5a=4

4.4-a=4

-a=-0.4

a=0.4

Apple=$0.4
