I need help with this please because I don’t know how to do it and I never learned it before.

Answer:

1) 21

2a) -23/30

2b) 6/55

Step-by-step explanation:

1) 3(x + 2) + 5x + 7

expand the brackets:

= 3x + 6 + 5x + 7

collect like terms:

= 8x + 13

when x = 1, (just substitute 1 for x)

8(1) + 13

= 8 + 13

= 21

2a)

-9/10 + 2/15

put both fractions on the same denominator (often we can just multiply each denominator by the other one):

so -9/10 * 15/15

= -135/150

and 2/15 * 10/10

= 20/150

now they're both on the same denominator and we can add the numerators:

-135 + 20 = -115

so our answer is:

-115/150

which we can simplify to:

-23/30

2b)

3/11*2/5

Multiplying fractions is very simple, as it doesn't require to have the same denominators. We can just multiply the numerators by each other and same for the denominators:

3*2 = 6

11*5 = 55

therefore, our answer is:

6/55

A)

3(x+2) + 5x + 7

3x + 6 + 5x + 7

3x + 5x + 6 + 7

put x = 1

3(1) + 5(1) + 6 + 7

3 + 5 + 6 + 7

21

B)

a)

[tex]\sf \rightarrow -\dfrac{9}{10} + \dfrac{2}{15}[/tex]

[tex]\sf \rightarrow -\dfrac{9(15)}{150} + \dfrac{2(10)}{150}[/tex]

[tex]\sf \rightarrow -\dfrac{135}{150} + \dfrac{20}{150}[/tex]

[tex]\sf \rightarrow \dfrac{-135+20}{150}[/tex]

[tex]\sf \rightarrow \dfrac{-115}{150}[/tex]

[tex]\sf \rightarrow \dfrac{-23}{30}[/tex]

b)

[tex]\sf \rightarrow \dfrac{3}{11} \ * \ \dfrac{2}{5}[/tex]

[tex]\sf \rightarrow \dfrac{3*2}{11 *5}[/tex]

[tex]\sf \rightarrow \dfrac{6}{55}[/tex]

Answer:

D

Step-by-step explanation:

Letter D is the only answer that gets the transformation of triangle ABC correct, since it is the only answer that describes a reflection across line p.

Letter A describes a reflection across the y-axis, which is incorrect because the triangle on the right is farther away from the y-axis than the triangle on the left.

Letter B describes a reflection across the x-axis, which is incorrect because the topmost triangle is farther away from the x-axis than the bottommost triangle.

Letter C once again describes a reflection across the y-axis, which is incorrect for the same reason as to why letter A is incorrect.

Therefore, the answer must be letter D.

Answer: 13.8

Step-by-step explanation:

Answer:

72 ounces.

Step-by-step explanation:

Convert all the fractions to denominator of 24

9/24 4/24 10/24 = 23/24

23/24 = 69/1 so you can cross multiply ( i think)

Then you get 1656 / 23 which equals 72.

If this is wrong I am so sorry

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

Explanation:

He uses 3/8 of the amount to make bread, 1/6 of the amount to make pancakes, and 5/12 of the amount to make jam.

Add up those fractions. But first let's make each fraction have the LCD (lowest common denominator) of 24

3/8 = 9/24 .... multiply top and bottom by 3

1/6 = 4/24 .... multiply top and bottom by 4

5/12 = 10/24 .... multiply top and bottom by 2

Now we can add the fractions:

(3/8) + (1/6) + (5/12)

(9/24) + (4/24) + (10/24)

(9+4+10)/24

23/24

So in total, Wayne used up 23/24 of all the blueberries he bought.

Let's make this unknown amount x

x = amount of blueberries he bought, in ounces

Multiplying the sum we got (23/24) by x leads to the amount of blueberries he used, which is 69 ounces

So,

(fraction used)*(amount he bought) = (amount he used)

(23/24)*x = 69

23x = 69*24 .... multiply both sides by 24

23x = 1656

x = 1656/23 ... divide both sides by 23

x = 72

He bought 72 ounces of blueberries.

------------------------------

Let's check that answer

A = 3/8 of 72 = (3/8)*72 = 27 = amount used for bread

B = 1/6 of 72 = (1/6)*72 = 12 = amount used for pancakes

C = 5/12 of 72 = (5/12)*72 = 30 = amount used for jam

A+B+C = 27+12+30 = 69 = total amount used

This confirms our answer.

Answer:

  58. 2 real roots; see attached for a graph

  59. -6, 3

Step-by-step explanation:

58. A graphing calculator graphs this easily. The graph is shown in the attachment. There are 2 x-intercepts, hence 2 real roots.

__

59. The x-intercepts are (-6, 0) and (3, 0), so the x-values x=-6 and x=3 satisfy the equation y = 0.

Angles 2·x + 2, and x + 50, formed by the transversal are alternate

exterior angles, which gives, x = 48°, the correct option is therefore;

A) 48

From the position of the angles image showing two parallel lines having

a common transversal we have;

Angle 2·x + 2 and angle x + 50 are alternate exterior angles

The alternate exterior angles formed by two parallel lines that have a

common transversal are equal, therefore;

2·x + 2 = x + 50

Which gives;

2·x - x = 50 - 2 = 48

x = 48°

Step-by-step explanation:

The aquarium would have a volume of 103950 cubic inches. Its dimensions are shown  in the image attached.

An aquarium is a container, often made of glass or acrylic, in which aquatic plants and animals are kept for display or research purposes. It can also be a building or room that houses such tanks.

We have been told that the volume of the water that can be held by the aquarium is 450 gallons of water. If we convert the gallons to cubic inches we would obtain 103950 cubic inches. The dimensions of the aquarium must therefore be such that it would a volume of 103950 cubic inches.

Answer:

53712.4

Step-by-step explanation:

[tex]53.7124 * 10^{3}[/tex] This is the scientific notation, and since we do not have a negative exponent, we can assume that the decimal is going to move to the right, because when it's negative, the decimal will move to the left, making a smaller number.

So, when we move the decimal 3 times to the right, we find it sitting at 53712.4

Answer:

n < - 0.6

Step-by-step explanation:

- 4n + 0.3 > 2.7

- 4n > 2.7 - 0.3

- 4n > 2.4

[tex]\frac{-4n}{-4}[/tex] < [tex]\frac{2.4}{-4}[/tex]

n < - 0.6

n ∈ ( - ∞ , - 0.6 )

-4n+0.3 > 2.7

-4n+0.3 -3.2 > 2.7-3.2 (Subtract 0.3 from both sides)

-4n > 2.7 - 0.3

-4n > 2.4

-4n/-4 > 2.4/-4 (Divide both sides by -4)
