Answer:

Exact response: Use the associative property to move the parentheses, and the expression becomes (d + 8d) + 1 + 7. Combine like terms, and the expression becomes 9d +8. Use the commutative property to change the order of the terms, and the expression becomes 8 + 9d.

Find the value of x if y=2.5 on the graph of 2x-1=y
Romashka-Z-Leto [24]

Answer:

2x - 1 = y

2x - 1 = 2.5

Use inverse operations

2.5 + 1 = 3.5

3.5 / 2 = 1.75

2 x 1.75 - 1 = 2.5

x = 1.75

Please help me solve this problem
Alla [95]

Answer:

Option B , D and E are correct.

Step-by-step explanation:

We set the denominator equal to zero to find the number to put in division box

So, if 3 is in the division box then the denominator will be

x-3 = 0 => x=3 is the root.

So, Option E is correct

2x^2-2x-12 ÷ x-3 = 2x+4 is correct.

because after division the result given is 2x+4 which is correct.

So, Option B is correct

x-3 is a factor of 2x^2-2x-12 because because when the term is divided we get the remainder 0.

So, Option D is correct

So, Option B,D and E are correct.

Calculate 6¾% tax on $2,305 a.$15.56 b.$145,22 c.$146,14 d.$155,59.
skad [1K]
Hello! 6 3/4 is equivalent to 6.75. So basically, you would be paying 6.75% tax. To find the amount of tax, multiply the price by the percentage rate. 2,305 * 6.75% (0.0675) is 155.5875 or 155.59 when rounded to the nearest hundredth. You would pay $155.59 in tax. The answer is D.
