Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65. If Hugh bought

3 magazines, how many books did he buy?
The equation that models the problem is 3.95m + 8.95b = 47.65, where m is the number of magazines and b is the number of books.

Answer:

4 books

Step-by-step explanation:

Our problem here is:

(3.95)3+8.95b=47.65

So we have to find B, and that will be our answer (the number of books).

1. Simplify the expression

3.95\cdot 3+8.95x=47.65

Combine like terms:

11.85+8.95x=47.65

2. Group all constants on the right side of the equation

11.85+8.95x=47.65

Subtract  from both sides:

11.85+8.95x-11.85=47.65-11.85

Group like terms:

8.95x+11.85-11.85=47.65-11.85

Simplify the arithmetic:

8.95x=47.65-11.85

Simplify the arithmetic:

8.95x=35.8

3. Isolate the x

8.95x=35.8

Divide both sides by 8.95:

\frac{8.95x}{8.95}=\frac{35.8}{8.95}

Simplify the arithmetic:

x=\frac{35.8}{8.95}

Simplify the arithmetic:

x=4

<h2>Hence, the number of books is 4</h2>

You are cycling around Europe with friends.
Dmitrij [34]

Options are:

Impossible

Certain

Likely

Unlikely

Answer:

Unlikely

Step-by-step explanation:

A ferry is a large ship that carries passengers and loads on water.

A ferry rarely sinks. Infact, the United States experience very low cases of shipwreck yearly. According to wikipedia in 2018, not more than 200 shipwrecks happened all over the world compared to a great number of operations that year.

Therefore, based on statistics, the ferry is unlikely to sink.

I NEED HELPP PLZ Which equation best represents the relationship shown in this graph?
Dafna11 [192]

Answer:

y = 2x

the formula for linear equations are y = mx+c,

where m is the gradient,

and c is the y-intercept

to find m (the gradient):

1. pick to points on the graph (eg. -2,-4 and 2,4)

2 substitute the values into the formula for gradient y2-y1/x2-x1.

m = y2-y1/x1-x2

= -4 -4/-2-2

= -8/-4

= 2

to find c (y-intercept):

- the y-intercept is where the graph cuts the y axis

- in this graph, the y-intercept is 0

hence,

c = 0

substitute m = 2 and c = 0 to y = mx+c,

y = 2x + 0

y = 2x

hence, the equation that best represents the relationship shown in the graph is y = 2x.

Supplementary angles add up to 180°

-> The measure of an angle that is supplementary to a 71° angle is 180° - 71° = 129°
