A ticket to a baseball game costs $32. Each soda at the game costs $4. Shawn may spend no more than $50. He buys 1 ticket and x
leonid [27]

Answer:

32 + 4x ≤ 50

Step-by-step explanation:

Cost of tickets = $32

Cost of soda = $4

Total spent = $50

When we say "no more than", we mean less than or equal to (≤)

He buys 1 tickets and x sodas

32 + 4x ≤ 50

4x ≤ 50 - 32

4x ≤ 18

Divide both sides by 4

x ≤ 18 / 4

x ≤ 4.5

Shawn can buy more than 4 sodas

Which graph shows the solution to the following inequality?<br>4d- 6 &lt; 18 <br>PLEASE HELP​
kenny6666 [7]

Answer:

answer a

Step-by-step explanation:

4d-6 < 18

  • Let's isolate d on one side of the equation. Ignore the inequality for now. We'll deal with that later.

4d-6=18\\4d-6+6=18+6\\4d=24\\\frac{4d}{4}=\frac{24}{4}\\ d=6

  • Now, I'm going to bring back the inequality or < symbol. I only removed it when simplifying and isolating d, but if this confuses you, just do your math and keep the inequality there.

d < 6

  • On a number line, this would include every number <em>less than </em>6, due to the < (less than) symbol. This disqualifies answers b and d because they are showing every number <em>greater than </em>6. But, how do we decide between answers a and c?
  • If a line has point at its beginning, 6, then that means that every number <em>less than or equal to</em> [ ≤ ] 6 is being shown, but our equation just says <em>less than </em>[ < ] 6, so answer a is our correct answer.

Can someone help me with number nineteen
garik1379 [7]

Answer:  \frac{15}{52}, Less

<u>Step-by-step-explanation:</u>

This year: \frac{Day 4}{Day 1 + Day 2 + Day 3 + Day 4} = \frac{15}{13+12+12+15} = \frac{15}{52}

Last year: \frac{Day 4}{Day 1 + Day 2 + Day 3 + Day 4} = \frac{15}{10+8+10+12} = \frac{12}{40}  = \frac{3}{10}

Compare this year's with last years by converting the fractions to decimals:

This year: \frac{15}{52} = 0.288

Last year: \frac{3}{10} = 0.300

This year (0.288) is less than last year (0.300)

locksmith larry charges $90 for a house cal plus $20 per hour. Locksmith Barry charges $50 for a house call plus $30 per house.
nadya68 [22]

Answer:

<u>4 hours</u>

Step-by-step explanation:

Equations :

Larry : <u>y = 20x + 90</u>

Barry : <u>y = 30x + 50</u>

Equate both to find the number of hours at which they both charge the same :

  • 20x + 90 = 30x + 50
  • 30x - 20x = 90 - 50
  • 10x = 40
  • x = <u>4 hours</u>
