Choose the symbol to make the following statement true. 4 yd. ___12 ft. A. C . =

Answers

Answer:

C. =

Step-by-step explanation:

Note the conversion for Yard to Feet.

1 yard = 3 feet.

In this case, it is given to you that there are 4 yards. Multiply 4 with 3 to get the amount of feet:

4 yd x 3 ft per yd = 12 feet per 4 yd.

12 ft. = 12 ft., ∴ 4 yd. = 12 ft.

(4y+8) ÷6-12

which is the variable?

what is the sum?

what is the quotient?

which is the coefficient?

Answers

Answer:

variable- y  this is it can vary on what number it is

sum- 4y+8

quotient- (4y+8) / 6

coefficient- 4

simplified it would be y+2-6-12

the answer to this problem is y+4

The variable, sum, quotient and coefficient in the equation 4y+8) ÷6-12 are y, 4y + 8, (4y + 8) ÷ -6 and 4 respectively.

Quotient

Quotient is the result obtained when a divisor is divided by a dividend.

Given:

(4y+8) ÷ 6 - 12

The variable is y

The sum is 4y + 8

Quotient = (4y + 8) ÷ (6 - 12)

= (4y + 8) ÷ -6

Coefficient = 4

The veterinarian told Hector that his 8-inch puppy would get no taller than 24 inches.

What inequality can you use solve to find how much more Hector's puppy may grow?

Answers

Less than or equal to. I don’t have the symbol but it is < with a _ under it. If his puppy can grow up to 24 inches but not more, then that symbol fits the answer. Hope this helps!

The inequality to find how much more Hector's puppy may grow is 8 -x ≤ 24.

What is Inequality?

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

The veterinarian told Hector that his 8-inch puppy would get no taller than 24 inches.

let the present height of Puppy be x.

So, 8 -x ≤ 24

Hence, the inequality to find how much more Hector's puppy may grow is 8 -x ≤ 24.
