-3 = -3

You're question is: x/7 < -3

Simplify it. Isolate the x. Multiply 7 to both sides

x < (-3)(7)

Simplify, multiply.

x < -21

x < -21 is your answer

String a is 35 centimeters long.string b is 5 times as long as string a .both are necessary to create a decorative bottle .find
yulyashka [42]
First you convert centimeters to meters which will be 35 centimeters-> 0.35 meters

Once you have that, you multiply String A's length (0.35 m) by 5 to find String B's length which will be 1.75 meters.

Now that you have the two lengths you multiply each by 17.
 
17 x 1.75 = 29.75 and 17 x 0.35 = 5.95

Now you just add 29.75 and 5.95 and you get your answer which is

A retail store sells two types of shoes, sneakers and sandals. The store owner pays $8 for the sneakers and $14 for the sandals.
soldier1979 [14.2K]

Answer:

134 sneakers and 66 sandals

Step-by-step explanation:

Sneakers= x, sandals= y

Profit rate:

  • sneakers: (10-2)/8= 25%
  • sandals: (17-14)/14= 21.4%

Sneakers are more profitable, so it should be maximized.

Cost:

8x+14y≤2000

x+y≤200

if we assume the maximum of 200 shoes stocked, then:

x= 200-y

8(200-y)+14y ≤ 2000

1600 - 8y +14y ≤ 2000

6y≤400

y≤66 and x=134 is the best option

Jess takes a board that is 50 inches long and cuts it into two pieces, one of which is 16 inches longer than the other. How long
sergey [27]
Let x = the length of the shorter piece
x+x+16=50in
2x=50-16
2x=34
x=17

Then

x+16=17+16
x+16=33
Subtract 16 from both sides

The lengths are 17in and 33in
