Answer:

x = −1/13 and y = 33/13 or 2 7/13

Step-by-step explanation:

x+2y=5

x+2(6x+3)=5

x+12x+6=5

13x+6=5

-6        -6

13x= -1

/13     /13

x= -1/13

y=6x+3

y=6(-1/13)+3

y= 33/13

y= 2 7/13

Answer:

7:8

Step-by-step explanation:

First, convert their times to common units. You'll want to put it in seconds:

5 minutes and 50 seconds = 350 seconds

- multiply 5 minutes by 60 to get it into seconds and then add the other 50 seconds to it

- for Elizabeth's time, multiply 6 by 60 seconds and add 40 to it

To get the ratio of their times, divide Alison's time by Elizabeth's time:

350 ÷ 400 = 7:8

Answer:

a) 7:8

Step-by-step explanation:

Alison: 5 minutes and 50 seconds = 355 seconds

Elizabeth: 6 minutes and 40 seconds = 400 seconds

355:400, reduces to 71:80 or 7:8

Answer:

(d)

Step-by-step explanation:

Given

See attachment for [tex]\triangle BCD[/tex] and [tex]\triangle B"C"D"[/tex]

Required

The transformations

Using B and B"" as points of reference, we have:

[tex]B = (1,4)[/tex]

[tex]B"" = (5,-1)[/tex]

The transformation is as follows:

First, reflect across y axis.

The rule is:

[tex](x,y) \to (-x,y)[/tex]

So, we have:

[tex]B(1,4) \to B'(-1,4)[/tex]

Next, translate 6 units right.

The rule is:

[tex](x,y) \to (x + 6,y)[/tex]

So, we have:

[tex]B' (-1,4) \to B"(-1 + 6,4)[/tex]

[tex]B' (-1,4) \to B"(5,4)[/tex]

Lastly, translate 5 units down

The rule is:

[tex](x,y) \to (x,y-5)[/tex]

So, we have:

[tex]B"(5,4) \to (5,4-5)[/tex]

[tex]B"(5,4) \to (5,-1)[/tex]

Hence; (d) is correct

The Perimeter of the polygon is 48 cm.

A polygon is a closed figure made up of three or more line segments connected end to end.

From the given diagram;

Perimeter of the polygon = AB + BC+ CD + DA

Perimeter of the polygon = 5 + 6 + 6 + 7 + 7 + 6 + 6 + 5

Perimeter of the polygon = 11 + 13 + 13+ 11

The perimeter of the polygon = 48

Hence the Perimeter of the polygon is 48 cm.

This is a rectangular prism,

Here length = 16 m

Width = 6 m

Height = 3 m

Surface area of rectangular prism = 2( bl + lh + hb )

Where,

b – base length of the rectangular prism.

l – base width of the rectangular prism.

h – height of the rectangular prism.

Putting these values, surface area = 2(16×6 + 16×3+ 3×6)

= 2( 96+48+18) = 2×162 = 324m

hope you get it well :)

Answer:

3 and 4

Step-by-step explanation:

The number of hardcover books will be 3,4, and 8.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Tim is sorting his book collection into groups. He places each group onto bookshelves that can each hold a maximum of 25 pounds. His collection includes hardcover books that weigh 3 pounds each and softcover books that weigh 2 pounds each.

Total weight = 25 pounds

The number of hardcover books which weigh less than 25 pounds is,

3 x 3 pounds = 9 pounds

4 x 3 pounds = 12 pounds

8 x 3 pounds =- 24 pounds

Therefore, the number of hardcover books will be 3,4, and 8.

Answer:

Step-by-step explanation:

There are 3 bags to be shared among 7 people.

Therefore each person will get 3/7    bags.

I couldn't think of a way of explaining the question in terms of bags when I wrote my answer. Suppose you try this.

Weigh each bag separately.

Add the weights (or masses) together.

Divide by 7

Another way is to weigh each bag separately. There are three bags and seven people. Each person will get 3 parts of the total divided by 7.

This will solve the problem in a practical manner. Give the Brainliest to the other responder who did a much better job of explaining it than I have.

Answer:

[tex]\frac{7}{3}[/tex] or 2[tex]\frac{1}{3}[/tex] of a bag of trail mix

Step-by-step explanation:

To find the fraction of trail mix each friend will get, divide the number of friends by the number of bags of trail mix:

Since there are 7 friends and 3 bags of trail mix, the fraction will be [tex]\frac{7}{3}[/tex]

This can also be simplified to a mixed fraction, 2[tex]\frac{1}{3}[/tex]

So, each friend will receive [tex]\frac{7}{3}[/tex] or 2[tex]\frac{1}{3}[/tex] of a bag of trail mix.

Number of cookies sold is 2000 and number of cupcakes sold is 1500

Step-by-step explanation:

Let number of cookies be [tex]x[/tex]

and number of cupcakes be [tex]y[/tex] so

[tex]x+y=3500[/tex]

Cost of one cookie is $0.75

Cost of one cupcake is $2

[tex]0.75x+2y=4500[/tex]

[tex]x+y=3500[/tex] [tex]\times 2[/tex]

[tex]2x+2y=7000[/tex]

[tex]-1.25x=-2500\\\Rightarrow x=\dfrac{2500}{1.25}\\\Rightarrow x=2000[/tex]

[tex]y=3500-x=3500-2000\\\Rightarrow y=1500[/tex]

Number of cookies sold is 2000 and number of cupcakes sold is 1500.
