Sally's soccer team played 25
games and won 17 of them.

What percent did the team LOSE?

Step-By-Step explanation please, I need to get this finished by tonight at 11:59 p.m!​

Answers

The team lost 32% of the games.

The team won 17/25 games. To find the number of games they lost, we would have to subtract 17 from 25. 25 - 17 = 8. This means the team lost 8/25 games. There are two ways I can think of. You can simply multiply 8/25 by 4/4 because 25 times 4 would equal 100. This would give you the percentage of 32. Another way is to write it like this: 8/25 = x/100. You would cross cancel to get 800 = 25(x) and divide both by 25. This would also give the answer of 32.

5. Alani paid $8.50 to get in the movies. Before she left home her parents
gave her $20 to spend. If she bought candy that cost $3 each, how many
pieces of candy can she buy without going over the $20?

Answers

Answer:

3 peices

Step-by-step explanation:

Answer:

she can buy 3 pieces of candy

Step-by-step explanation:

1. subtract the price of the ticket from $20

  20 - 8.5 = 11.5

2. she has $11.50 left. divide that by the price of a piece of candy

  11.5 / 3 = 3.83

she cannot buy 0.83 of a piece of candy, so you round down to the nearest whole number, which is 3.

Can someone plz explain how to find the slope in a graph. I don't care if yall pick different numbers i just need to understand to find the slope. I learned this last year, but eng is making me learn it again this year, and i forgot how to find stuff. And im too dumb to know how to do it.

Answers

Answer:Using the Slope Equation

Pick two points on the line and determine their coordinates.

Determine the difference in y-coordinates of these two points (rise).

Determine the difference in x-coordinates for these two points (run).

Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).Step-by-step explanation:

The slope equals the rise divided by the run: Slope =riserun Slope = rise run . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it.

7,13,19,25 write an equation to find the nth term of each sequence. Then find a24

Answers

Answer:

[tex]\boxed {a_{24} = 145}[/tex]

Step-by-step explanation:

According to the following pattern sequence ([tex]7, 13, 19, 25[/tex] ), it is Arithmetic Sequence, because every number is added by [tex]6[/tex]. So, to find the 24th term, you need to use the Arithmetic Sequence Formula and solve to find the 24th term:

[tex]a_{n} = a_{1} + (n - 1) d[/tex]

[tex]a_{n}[/tex]: nth term in the sequence

[tex]a_{1}[/tex]: 1st term

[tex]n[/tex]: term position

[tex]d[/tex]: Common difference

-Apply to the formula:

[tex]a_{24} = 7 + 6 (24 - 1)[/tex]

[tex]a_{n} = a_{24}[/tex]

[tex]a_{1} = 7[/tex]

[tex]n = 24[/tex]

[tex]d = 6[/tex]

-Solve:

[tex]a_{24} = 7 + 6 (24 - 1)[/tex]

[tex]a_{24} = 7 + 6 (23)[/tex]

[tex]a_{24} = 7 + 138[/tex]

[tex]\boxed {a_{24} = 145}[/tex]

Therefore, the 24th term is [tex]145[/tex].

The 24th term of the sequence is 145

7, 13 , 19, 25

The sequence is an arithmetic progression. Therefore, let's use arithmetic progression formula for nth term to find the 24th term.

Arithmetic progression:aₙ = a + (n - 1)d

where

a = first term

d = common difference

n = number of term

Therefore,

d = 13 - 7 = 6

a = 7

a₂₄ = 7 + (24 - 1)6

a₂₄ = 7 + (23)6

a₂₄ = 7 + 138

a₂₄ = 145

Therefore, the 24th term of the sequence is 145

Step-by-step explanation:

let the smaller number = x, let the larger number = y

then...

x + y = 64

5x + 2y = 20

use substitution:  y = (64 - x)

5x + 2(64 - x) = 20

3x = 20 - 128 = - 108

x = - 36
