Answer:

8 x + 25y ≥100

x+y ≤ 14

Step-by-step explanation:

Hi, to answer this question we to write a system of inequalities.

First inequality:

The product of the earnings per hour working at culvers (8) and the number of hours worked there, plus the product of the earnings per hour mowing lawns (8) and the number of hours mowing must be greater or equal to $100.

Second inequality:

The amount of time he works at culvers (x) plus the amount of time he works mowing lawn (y) must be less or equal to 14 hours.

8 x + 25y ≥100

x+y ≤ 14

Where:

x = number of hours worked at Culvers

y= number of hours worked Mowing lawns

$- x + 1 = 4x - 14 \\ - x - 4x = - 14 - 1 \\ - 5x = - 15 \\ x = 3$

Substitute x = 3 in any given equations. I will do in y = - x + 1

$y = - x + 1 \\ y = - 3 + 1 \\ y = - 2$

Therefore the answer is (3,-2)

Help!

Andru [333]

Answer:

21 Students played string instruments

Step-by-step explanation:

58 - 16 = 42, 42 ÷ 2 = 21 so 21 + 21 + 16 = 58. because there are sixteen more wind instruments that means you need to have the wind and string equal and then add 16 more winds which is what i did, if you have 21 string instruments and (21+16) 37 wind instruments then you have 58

Pizza Palace and Saucy Sam’s both offer food delivery. Both have a deal for large pizzas. You have to buy a lot of pizzas for yo

pochemuha

Answer:

Now lets add up how much it would cost for a SINGLE pizza at both pizza places, which I am rounding up to the next dollar for this.

Step-by-step explanation:

Pizza Palace:

5 + 9 = 14

Meaning, if you were to get many pizzas, just a single one delivered costs 14 bucks, but all you have to do to add more pizzas to it is:

5 + 9p = ?, where p is the number of pizzas ordered

Saucy Sam's:

5 + 12 = 17

Meaning, if you were to get many pizzas, a single one delivered costs 17 bucks, but all you have to do to add more pizzas to it is:

5p + 12 = ?, where p is the number of pizzas ordered

BUT, heres where it tricks you, lets take both equations and choose a number that equals P. We can choose........ 10.

5 x 10 + 12 = 62

This means, that 10 pizzas of Saucy Sam's costs 62 dollars

5 + 9 x 10 = 95

This means, that 10 pizzass of Pizza Palace costs 95 dollars.

Saucy Sams has the best price.

A town planner wants to build two new streets, Elm Street and Garden Road, to connect parallel streets Maple Drive and Pine Aven

Advocard [28]

Answer:

72°

Step-by-step explanation:

From the information given:

A town planner wants to build two new streets, Elm Street and Garden Road, to connect parallel streets Maple Drive and Pine Avenue.

We are also told that there is a Trapezoid EFGH with EH as the Pine avenue and EF as the Elm street.

However, side FG and EH are parallel.

∠G = 108°

From the property of parallel lines :

since FG || EH

Then ∠G = ∠H = 108° (i.e corresponding angle will also be equal)

The required angle between Elm Street and Pine Avenue would be interior angles + 180° given that alternate angles are also equal.

The required angle between Elm Street and Pine Avenue = 180° - 108°

The required angle between Elm Street and Pine Avenue = 72°
