The total cost of ears of corn at the grocery depends upon how many ears of corn you buy.Five ears cost $1.50, and 8 ears cost $

Gre4nikov [31]

It would be ‘F’, because 0.30 times 8 is 2.40, and 0.30 times 5 is 1.50, so the constant rate would be 0.30 cents per corn

Solve for x (picture is included below)

Anna11 [10]

Solve for x:

1.

4x - 7 = 3

Add 7 to both sides

4x = 10

Divide both sides by 4

x = 10/4

Simplify:

x = 5/2

Answer for question 1: x = 5/2

2.

13 + 2x/3 = 15

Multiply both sides by 3

39 + 2x = 45

Subtract 39 from both sides

2x = 6

Divide both sides by 2

x = 3

Answer for question 2: x = 3

3.

10x + 7 = 15

Subtract 7 from both sides

10x = 8

Divide both sides by 10

x = 8/10

Simplify

x = 4/5

Answer for question 3: x = 4/5

Which of the following expressions are equivalent to (6.2+6.2)+9.4(6.2+6.2)+9.4left parenthesis, 6, point, 2, plus, 6, point, 2,

ELEN [110]

Answer:

6.2 + (6.2 + 9.4) ⇒ A

6.2 - (-6.2 - 9.4) ⇒ E

Step-by-step explanation:

* Lets revise some definitions to solve the problem

- Associative property states that you can re-group numbers and you

will get the same answer [(a + b) + c = a + (b + c)]

- Additive inverse of a number means reverse the sign of the number

the additive inverse of x is -x

- The expression is (6.2 + 6.2) + 9.4

- We want to find which of the following expressions are equivalent

to this expression

- By using associative property we can write the expression as

6.2 + (6.2 + 9.4)

∴ (6.2 + 6.2) + 9.4 = 6.2 + (6.2 + 9.4)

- Multiply (-) by the additive inverse of number is the number itself

If a number is x and its additive inverse is -x, then (-) × (-x) = x

∵ -6.2 is additive inverse of 6.2

∵ (-)(-6.2) = 6.2

∵ -9.4 is additive inverse of 9.4

∵ (-)(-9.4) = 9.4

∴ 6.2 - (-6.2 - 9.4) = 6.2 + 6.2 + 9.4

∴ (6.2 + 6.2) + 9.4 = 6.2 - (-6.2 - 9.4)

* The answers are A and E

Please help me. I desperately need to pass Math T-T

Ad libitum [116K]

Answer:

60 degrees

Step-by-step explanation:

C = 2(pi)r

The radius is 12 cm. We can find the circumference of a circle with radius 12 cm.

C = 2(pi)r = 2(3.14)(12 cm) = 75.36 cm

The length of the arc of the sector is 12.56 cm.

We can find the fraction this length is of the full circumference.

(12.56 cm)/(75.36 cm) = 1/6

The length of the arc of this sector is 1/6 the length of the circumference of the entire circle.

That means the angle of the sector is 1/6 the angle of an entire circle.

An entire circle has a central angle of 360 degrees.

1/6 * 360 degrees = 60 degrees
