Answer:

C

Step-by-step explanation:

simplifying c gives us 5/8x + 2.5 = 5/8x + 1.5 , which then gives us

2.5=1.5 , which is impossible, so it must be c

Standard form must have a single digit number x10 to the power of a number.

Here, we had to move the decimal point three times to the left, therefore it will be a power of positive three for the 10.

Answer:

Negative

Step-by-step explanation:

The slope is negative because as the x values increase, the y values decrease. If the line was going upward as the x values increase, it would be positive. If the line would be straight accross, it would be zero because the x values increase and the y values decrease.

Answer:

Refute/Disagree

Step-by-step explanation:

My answer(I did the test): I refute the authors claim. The chart clearly shows that at the end 16 year olds and 17 year olds are both at the same rate if likeness of committing a moving violation. The least likely to commit a moving violation during the first 8 months is the 16 year old and 6 month drivers. You can find a more accurate answer by adding up all the percentages for each age and then divide it by 8 (months), this number is the overall percentage for the 8 months.

Answer:

5.99

Step-by-step explanation:

height of sign = x

length of sign shadow = 7m

For sign:-

[tex]tan \theta = \frac{p}{b} = \frac{height}{shadow} = \frac{x }{7} [/tex]

height of man = 1.6m

length of man shadow= 4m

For man :-

[tex] \tan\theta = \frac{p}{b} = \frac{height}{shadow} = \frac{1.6}{4} [/tex]

tanθ is same bez sun is at same level (angle) for both of them

So according to questions :-

[tex] \tan( \theta) = \frac{x}{7} = \frac{1.6}{4} \\ \frac{x}{7} = \frac{ \cancel{1.6}^{ \: \: 0.4} }{ \cancel4} \\ x = 7 \times 0.4 \\ x = 2.8m \: [/tex]

so we can say height of the sign = x = 2.8 m

Answer:

a sandwich = $30

Reason why is because when it added 2 more sandwiches it added 70 with 30 2 times which equals 130.

Answer:Bill did

Step-by-step explanation:

12.5x10=125

Convert to x in terms of y.

3x + 6y = 12

Divide by 3.

x + 3y = 4

Subtract x.

3y = -x + 4

Divide by 3.

y = (-1/3)x + 4

The slope is -1/3 here. A parallel line would have the same slope.

So the slope of the parallel line is -1/3

(A.) If a polygon is a pentagon, then it has five angles.

The inverse of the conditional statement "If a polygon has five angles, then it is a pentagon" is "If a polygon does not have five angles, then it is not a pentagon."

Option C is the correct answer.

A pentagon is a polygon that has five sides and five angles.

The sides and angles of a pentagon are not all equal unless it is a regular pentagon.

A regular pentagon has five equal sides and five equal angles.

We have,

The inverse of a conditional statement is formed by negating both the hypothesis and the conclusion.

In this case, we negate the statement "a polygon has five angles" to "a polygon does not have five angles," and negate the statement "it is a pentagon" to "it is not a pentagon."

Thus,

The inverse of the conditional statement "If a polygon has five angles, then it is a pentagon" is "If a polygon does not have five angles, then it is not a pentagon."

Answer:

(2)3 • (2x - y)3

Step-by-step explanation:

Put the exponent aside and simplify the base by pulling out like factors

4x-2y  =  2 • (2x-y)

Remember the 4th law of exponents : (a • b)m= am• bm

Retract the exponent and apply the 4th law to the simplified base: ( 2 • (2xy) )3 =  (2)3 • (2x-y)3  

Answer:

7≥t

Step-by-step explanation:

The tank already has 13litres of water in it.

Keisha plans on increasing the quantity of the water to 41 litres. Hence,

41 litres - 13litres = 28litres

The above implies that she needed 28litres to be added to the fish tank.

She adds 4 litres per minute

Now, the question can now be reframed as how many minutes will be needed to add 28litre.

Considering to proportion method

4litres = 1 minute

28litres = t minutes

4litres × t minutes = 28litres

t = 28/4

t = 7 minutes

Hence, at least 7 minutes will be needed to increase the quantity of the tank water from 13litres to 41litres

But since we are to write the answer in an inequality form.

41≥ 13+4t

Solve for t

41≥13+4t

41-13≥4t

28≥4t

Divide both sides by 4

28/4≥4t/4

7≥t

Hey there!

In order to factorise an expression, we need to factor out the greatest common factor (divide all the terms in the expression by the greatest common factor):

6ac-4ad

In this case, the greatest common factor is 2a.

Put it outside the parentheses:

2(3c-2d)

That's the answer.

Hope everything is clear.

Answer:C =$65 + $30G

Step-by-step explanation:

Given that :

Base fee charge = $65

Overage charge = $30 / per gigabyte for data that exceeds 2 gigabyte

C = cost ; G = total amount of gigabyte

Equation to represent plan; if more than 2 gigabyte are used :

Cost (C) = Base charge + (average charge * amount of gigabyte)

C = $65 + ($30 * G)

C =$65 + $30G
