Answers

Answer: Choice b) [tex]x \ge 120[/tex]

The graph will involve a closed filled in circle at 120, with shading to the right.

See the diagram below.

============================================

Explanation:

The phrasing "at least" means "that amount or more".

Saying "at least 120" is the same as "120 or more".

Therefore, x = 120 is the smallest x can be. That's why we go for [tex]x \ge 120[/tex] which says that either x = 120 or x > 120.

Visually, we'll plot a closed filled in circle at 120 on the number line. The shading will aim to the right to indicate all values larger than 120. The closed/filled in circle is to represent we include 120 (as opposed to an open circle where we exclude it).

Due to the fact that your teacher gave you a blank number line, the placement of 120 doesn't really matter.

Number the lines by 60’s. The numbers on the left are negative and the numbers in the right are positive. Also, put a middle dot i t eh middle. Now, go two lines down (60, 120). when it has the line under it, it means at least basically. This brings it down to two answers. The answer is B. x can be equal to or larger than 120 which means at least 120. Finally, put the dot on the second line on the right.

Answers

Answer:

3(x-5)+1=2+x

3x-15+1=2+x

3x-x=2+15-1

2x=16

x=8

Answer:

x=8

Step-by-step explanation:

3(x-5)+1=2+x

Subtract 1 from both sides.

3(x-5)=1+x

Distribute the 3

3x-15=1+x

Add 15 to both sides.

3x=16+x

Subtract x from both sides.

2x=16

Divide both sides by 2.

x=8

The mayor knows the area needed for a flower garden in the park. She wants the base to be a certain length. How can she determine the necessary height to get the correct area of the flower garden? Explain.

Answers

Answer:

Answer:The formula for the area of a parallelogram is A = bh, and the formula for area of a triangle is A = 1/2bh. Since a triangle is half of the area of a parallelogram with the same base and height, the only difference in the formula is 1/2.

Step-by-step explanation:

Maria would determine the height by dividing the area of the garden by the base

From the question, she has the area and the base.

Also, the garden has the shape of a parallelogram

The area of a parallelogram is the product of the base and the height.

So, when the area is divided by the base, she gets the height

A bookshop has some fiction and non books. 2/5 of the books are fiction books. Of these, 1/5 are mystery stories. 1/3 of the non fiction books are mystery stories too. What fraction of all the books in the shop are mystery books?

Answers

Answer:

1/3 of all of the books

Step-by-step explanation:

5/5 - (2/5 +1/5) =2/5

2/5(1/3) = 2/15 nonfiction mystery books

2/15 + 1/5 = mystery books

1/5 = 3/15

2/15 + 3/15 = 5/15

5/15 = 1/3

1/3 out of all the books

y = 3x + 5

Step-by-step explanation:

Based on the table, as x increases by 1, y increases by 3. Moreover, when x = 0, y = 5. Therefore, the slope is 3 and the y-intercept is (0, 5).

Substitute the information for the variables in the slope-intercept form equation.

Answers

Answer:

Step-by-step explanation:

You are to assume in both problems that the two triangles are similar. That is a very dangerous assumption -- especially in later math classes. But in this case, there is no other way to do the problem. The two sets of triangles look like they are proportional. So set up two ratios that are = to each other

On the left

long side small triange / long side large triangle = base small triangle / base large triangle

On the right

hypotenuse/longest leg = hypotenuse / longest leg.

Problem A

Set up the similar Proportion

5/40 = x/20 Cross Multiply

40x = 20*5

40x = 100 Divide by 40

x = 100/40

x = 2.5

Problem B

Again set up the similar triangle proportion

15/10 = x/2 Multiply by 2

15*2/10 = x

3 = x

for the first one x=2.5
for the second one x=3
