Answer:

<em>The numbers between -5 and 5</em>

Step-by-step explanation:

Intersection of Intervals

Given the intervals A,B,C,etc. The intersection of them all is the set of all values that are common to all the intervals.

We must find

$\{x | x > -5\} \bigcap \ \{x | x < 5\}$

which is the intersection between the intervals x > -5 and x < 5. The intersection represents all the numbers greater than -5 and less than 5. It can also be said The numbers between -5 and 5 (non inclusive), third option

Use greatest common factor and the distributive property to write equivalent expressions in factored form for the following expr

Nitella [24]

Answer:

a. 4(d+3e)

b. 6(3x+5y)

c. 7(3a+4y)

d. 8(3f+7g)

Step-by-step explanation:

In each case we find the greatest common factor of the numbers. That is the greatest number that goes into both the numbers. Then we factor it out in front and inside parentheses we divide each original term by the greatest common factor:

a. 4d+12e, GCF: 4

$\displaystyle4\left(\frac{4d}{4}+\frac{12e}{4}\right)=4(d+3e)$

b. 18x+30y, GCF: 6

$\displaystyle6\left(\frac{18x}{6}+\frac{30y}{6}\right)=6(3x+5y)$

c. 21a+28y, GCF: 7

$\displaystyle7\left(\frac{21a}{7}+\frac{28y}{7}\right)=7(3a+4y)$

d. 24f+56g, GCF: 8

$\displaystyle8\left(\frac{24f}{8}+\frac{56g}{8}\right)=8(3f+7g)$

5. Sally is shopping for diapers and sees a box with 216 diapers for $39.98 and a box with 88

Leya [2.2K]

Answer:

The option with the best deal is 216 diapers for $39.98

Step-by-step explanation:

Sally is shoping for diapers

Sally first sees a box which contains 216 diapers at $39.98

She also sees a second box with 88 diapers for $24.99

To know which option that has the best deal for diapers we have to calculate the amount of 1 diapers in each of the boxes

Box 1

216 diapers= $39.98

1 diaper= x

Cross multiply

216x= $39.98

x= 39.98/216

= 0.19 cents for 1 diapers

Box 2

88 diapers= $24.99

1 diaper= x

Cross multiply

88x= $24.99

x= 24.99/88

= 0.28 cents for 1 diaper

Hence the option with the best deal is 216 diapers for $39.98, this is because it is more cheaper.
