2/5(5x-3)+3/5=4x-1/5​

Answers

Answer:

x=-1/5

Step-by-step explanation:

[tex]\frac{2}{5} (5x-3)+\frac{3}{5} =4x-\frac{1}{5}[/tex]

Multiply both sides by 5:

2(5x-3)+3=20x-1

Distribute:

10x-6+3=20x-1

Simplify Like-Terms:

10x-3=20x-1

Add 3 to both sides:

10x=20x+2

Subtract 10x from both sides:

0=10x+2

Subtract 2 from both sides:

10x=-2

Divide by 10:

x=-2/10

or

x=-1/5

How many integers are there that consist of four digits (from 1000 to 9999) where the first digit is a 5 or an 8 and the third digit is not 5 or 8

Answers

Answer:

1600 integers

Step-by-step explanation:

Since we have a four digit number, there are four digit placements.

For the first digit, since there can either be a 5 or an 8, we have the arrangement as ²P₁ = 2 ways.

For the second digit, we have ten numbers to choose from, so we have ¹⁰P₁ = 10.

For the third digit, since it neither be a 5 or an 8, we have two less digit from the total of ten digits which is 10 - 2 = 8. So, the number of ways of arranging that is ⁸P₁ = 8.

For the last digit, we have ten numbers to choose from, so we have ¹⁰P₁ = 10.

So, the number of integers that can be formed are 2 × 10 × 8 × 10 = 20 × 80 = 1600 integers

Kristen is making accessories for the soccer team. She uses 595.56 inches of fabric on headbands for 39 players and 3 coaches. She also uses 343.59 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?

Answers

Answer:

22.99 inches

Step-by-step explanation:

According to problem, given data are as follows:

Fabric used for headband = 595.56 inches

Number of headbands made = 39 + 3 = 42

So, Fabric used per headband = 595.56 ÷ 42 = 14.18 inches per headband

Similarly, Fabric used for wristband = 343.59 inches

Number of wristbands made = 39

So, Fabric used per wristband = 343.59 ÷ 39 = 8.81 inches per wristband

So, Fabric used for each player = 14.18 inches + 8.81 inches

= 22.99 inches

help plz solve these equations by completing the square

x square + 12x =1

Answers

Answer:

x = - 6 ± [tex]\sqrt{37}[/tex]

Step-by-step explanation:

Given

x² + 12x = 1

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(6)x + 36 = 1 + 36

(x + 6)² = 37 ( take the square root of both sides )

x + 6 = ± [tex]\sqrt{37}[/tex] ( subtract 6 from both sides )

x = - 6 ± [tex]\sqrt{37}[/tex] ← exact solutions
