A grocery store clerk put only packages of flour tortillas and packages of corn tortillas on a shelf. The ratio of the number of
Mazyrski [523]

Answer:

9

Step-by-step explanation:

Let corn tortillas be represented by c, flour tortillas be represented by f and the total number of packages be t

such that

t = c + f     .... eq 1

ratio of c to t = 7 : 16 = 7/16

Therefore, t = 16,    c = 7

substitute the value of t in eq 1

16 =  7 + f

f = 16 - 7

f = 9

If AC=18x-7,find the x. Round to the nearest hundredth if necessary <br>AB=7x+29 <br>BC=30​
Margaret [11]

Answer:

x=6

Step-by-step explanation:

AC = AB + BC

18x-7=(7x+29)+30

18x-7=7x+29+30

18x-7=7x+59

Add 7 to both sides:

18x-7+7=7x+59+7

18x=7x+66

Subtract 7x from both sides:

11x=66

Divide both sides by 11:

\frac{11x}{11}=\frac{66}{11}

x=6

Find the most important variable in the problem.
natali 33 [55]

Answer:

A

Step-by-step explanation:

Let

x = the number of phone available

If it would require 8 more phones, then the total number of phones will be x + 8.

A company hired an additional 12 employees, and every employee needed a phone, then

x + 8 = 12

x = 4

This means 4 phones were available (and 8 more needed to total in 12 phones for 12 new employees)

Hence, correct option is option A.
