Which expression is equivalent to the expression below?

Answers

To answer this problem, we group the first the like terms, in this case, the terms 3/m2 and 16/m2. The difference between these two terms -13/m2. Hence, the overall expression is m - 13/m2 - 9/m + 4.

are these ratios equivalent? 45/75 and 3/5

Answers

Answer: Yes, 45/75 simplifies to 3/5
Yes, because if you multiply 45 and 5, it is 225. If you multiply 75 and 3, it is also 225. Just multiply right numerator with left denominator, then multiply left numerator with right denominator.

The measure of an angle is 7°. What is the measure of its supplementary angle?

Answers

Answer:

173

Step-by-step explanation:

supplementary means adding up the 2 angles make 180

7+173=180

Answer:

173 degrees

Step-by-step explanation:

Supplementary angles are angles that form 180 degrees. So subtract 7 from 180 to get the measure of the other angle (which would be 173 degrees).

which answer choice is equivalent to the expression (x+2)^2 - 6x+2?
a. x^2 - 2x+8x
b. x^2 - 2x+6
c. x^2 - 6x+4
d. -5x^2 +6

Answers

Answer:

(x+2)^2 - 6x+2

(x+2)^2 = (x+2).(x+2)

            = x(x+2) + 2(x+2)

           = xx + x2 + 2x +4 ( x2 = 2x)

           = x^2+ 4x +4

(x+2)^2 - 6x+2

x^2+ 4x +4- 6x+2

x^2+ 4x - 6x+2 +4

x^2- 2x+2 + 6 (b)

Another company charges $8 per month and $0.03 per minute used. Which equation below best respresents the total cost for the month, c, for m miuntes used?

Answers

Answer: c = 8 + 0.03m

Step-by-step explanation:

From the question, we are informed that a company charges $8 per month and $0.03 per minute used.

The equation that best respresents the total cost for the month, c, for m miuntes used will be:

c = 8 + (0.03 × m)

c = 8 + (0.03m)

c = 8 + 0.03m

For example if 10 minutes was used, the cost will be:

c = 8 + 0.03m

c = 8 + (0.03 × 10)

c = 8 + 0.3

c = $8.3

What does y=?? 10 POINTS
y = [ ? ]
5y-20
2y+25

Answers

Answer:

1st one)

y = 4

2nd one)

y = -12.5

Step-by-step explanation:

5y - 20 = 0

add 20 on both sides:

⇒ 5y - 20 + 20 = 0 + 20

⇒ 5y = 20

divide 5 on both sides

⇒ [tex]\frac{5y}{y} = \frac{20}{5}[/tex]

⇒ y = 4

2y + 25 = 0

subtract 25 on both sides

⇒ 2y + 25 - 25 = 0 - 25

⇒ 2y = -25

divide 2 on both sides:

⇒ [tex]\frac{2y}{2} = \frac{-25}{2}[/tex]

⇒ y = -12.5

the opposite of f is 96 and the hypotenuse is 100

so [tex]sinF=\frac{96}{100} or.96[/tex]

find sin g

the opposite of g is 28 and the hypotenuse is 100

Answer:

x ≈ 7.1

Step-by-step explanation:

The circumference of this circle is 2πx.

65/360 of that circumference is said to be 8

so we can solve x from

65/360 · 2πx = 8

which can be simlified to

2πx = 8 · 360/65

πx = 288/13

x = 288 / (13π) ≈ 7.1
