rugs Emporium installs carpet for $80 plus $9.50 per square yard of carpet carpets 4 U charges $120 for installation and $7.50 p

mihalych1998 [28]

The area of the carpet must be greater than 20 square yards for which Rugs Emporium charges more than Carpets 4U.

Explanation

Suppose, the number of square yards of carpet is $x$

Rugs Emporium charges $80 plus $9.50 per square yard of carpet. So, the total charge for $x$ square yards of carpet $= (80+9.50x) dollar$

Carpets 4U charges $120 for installation and $7.50 per square yard of carpet. So the total charge for $x$ square yards of carpet $=(120+7.50x) dollar$

If the Rugs Emporium charges more than Carpets 4U , then the inequality will be.....

$80+9.50x>120+7.50x\\ \\ 9.50x-7.50x>120-80 \\ \\ 2x>40\\ \\ x>20$

So, the area of the carpet must be greater than 20 square yards for which Rugs Emporium charges more than Carpets 4U.

Mice21 [21]

Answer:

0 is the probability that Tim will select a card labeled with a number 6.

Step-by-step explanation:

We are given the following in the question:

Number of cards = 4

Cards with labels:

1,3,5,7

Tim will select one card from the box. We have to find the probability that Tim will select a card labeled with a number 6.

Formula:

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

$\text{P(Label 6) = }\dfrac{0}{4}= 0$

0 is the probability that Tim will select a card labeled with a number 6. Thus, it is an impossible event.

Help me substitution method define variables

Rina8888 [55]

$\left \{ {{S=14+L} (I) \atop {S+L=124}(II)} \right.$

Substitute (I) into (II), we have:
 $S+L=124$
$(14+L)+L=124$
$14 + 2L = 124$
$2L = 124 - 14$
$2L = 110$
$L = \frac{110}{2}$
$\boxed{L = 55}$

Replace (II) in (I), we have:
 $S=14+L$
$S = 14+ 55$
$\boxed{S = 69}$

Answer:
each student sell:
Lori = 55 pizzas
Steve = 69 pizzas
