Step-by-step explanation:

Hi the answer to this is super easy what you have to do is to substitute x with the number given by the chart and you will get y
So if we want to do the first one it will be

Y = 4 x (1) - 3
Y = 4 - 3
Y = 1

For the second one we got x = 6
So we do the same thing but with 6 and say
Y = 4 x (6) - 3
Y = 21

It seems confusing at first but I’m sure you’ll get the hang of it

Answer:

404

Step-by-step explanation:

Simplify = 8 + 30 x 13 + 6

Left to right = 8 + 390 + 6

Result = 404

Leave a brainliest if this helped.

Answer:

404

Step-by-step explanation:

do the equation inside the brackets first (BIDMAS) - 5 x 6 = 30

48 / 6 = 8

8 + (30 x 13) + 6 = 38

30 x 13 = 390

8 + 390 + 6 = 404

The computer monitor to the right has a length of 44 inches and
a width of 38 inches. Find the length of the diagonal. Round your
answer to the nearest hundredth.

Answers

Answer:

58.14 inches

Step-by-step explanation:

Pitagoras:

Diagonal² = length² + width²

Diagonal² = 44² + 38²

Diagonal² = 1936 + 1444

Diagonal² = 3380

√Diagonal² = √3380

Diagonal = 58.137 = 58.14inches

At a local print shop, 4 copies can be made for $2. At this rate, how how many copies could be made for $12?

Answers

Answer:

Step-by-step explanation:

$2 divided by 4 equals 50 cents

50 cents per copy

$12 will get you 24 copies

Answer:

24 copies

Step-by-step explanation:

$2 ----- 4 copies

$1 ----- 4 ÷2= 2 copies

$12 ----- 2(12)= 24 copies

Alternatively, we can present our working this way:

For every $2, 4 copies can be made.

Number of sets of $2 in $12

= $12 ÷$2

= 6

Since there are 6 sets of $2 and each set of $2 can make 4 copies,

number of copies

= 6(4)

= 24 copies

The mean length of time, per week, that students at a certain school spend on their homework is 24.3 hours, with a standard deviation of 1.2 hours. Assuming the distribution of study
imes is normal, what percent of students spend more than 25 hours per week on homework?
Round
your answer to the nearest hundredth.

Answers

Answer:

21.1%

Step-by-step explanation:

(25 - 24.3) / 1.2 = 0.5833 z score = 78.9%

You need the percent that spend more than 25 hrs per week, so 100 - 78.9 = 21.1%

Iqbal and Sachin have bookshelves of the same size and holding books of the same sizes. Iqbal's shelf is 7/8 full and Sachin's shelf is 12/15 full. If 351 more books of the same size are distributed among them, then they can fill their shelves completely. How many books does Sachin have now?
a)
864

b)
865

c)
800

d)
850

Answers

Answer:

540 books

Step-by-step explanation:

It is given that Iqbal's shelf is 7/8 full ..

→ That Means we can say that, iqbal's shelf is (1 - 7/8) = 1/8 is Empty .....

Similarly,

Sachin's shelf is 12/15 full.

→ That Means we can say that, sachin's shelf is (1 - 12/15) = 3/15 is Empty.....

→ Both total Empty = (1/8 + 3/15)

Taking LCM of denominator ,

→ (15+24 /120)

→ 39/120

→ 13/40 part is Empty in both .

Now, it has been said that, when 351 more books are distributed among them , both shelves filled completely .

So, we can say that :----

→ 13/40 part ---------------- 351

→ 1 part ---------------------- 351*40/13 = 1080 = Total Books in Both Selves .

__________________

Now, since bookshelves of the same size and holding books of the same sizes ,,

→ Both have Books in Each = 1080/2 = 540 books .

can you please help me find X in this problem it is so confusing

Answers

Answer:

x = 25°

Step-by-step explanation:

There are different ways to get there.

The unmarked angle at bottom left is an alternate interior angle with the one at the top marked 50°. So, it is congruent to 50°.

That makes the angles along the line at the bottom be ...

50° +x° +105° = 180° . . . . . the measure of a linear angle

x° = 180° -155° = 25°

The unmarked angle at top right is a same-side interior angle relative to the one at bottom marked 105°. As such it is supplementary to 105°, and has measure ...

180° -105° = 75°

This angle (upper right) is an exterior angle to the triangle. As such, it is equal to the sum of the two "remote" interior angles of the triangle—the ones marked 50° and x°.

75° = 50° +x°

25° = x° . . . . . . . subtract 50°

The unmarked interior angle of the triangle is an alternate interior angle with the one marked 105°. So, it is congruent to 105°. The sum of the triangle interior angles is 180°, so you have ...

x° +50° +105° = 180°

x = 180° -155° = 25° . . . . as we had with our first approach

Make x the subject of the formula: y=x^{2} + 5

Answers

First, multiply both sides by (x - 5), so you end up with:

(x-5)y = x + 2

Which can be expanded to give you:

xy - 5y = x + 2

Now add 5y to both sides to obtain:

xy = x + 2 + 5y

Now subtract x from both sides:

xy - x = 2 + 5y

Factorise x out:

x(y - 1) = 2 + 5y

Divide both sides by (y - 1):

x = 2 + 5y/y - 1

There you go, x is now the subject.

Complete each statement to adjust the ingredients for each new situation if Sherry uses this recipe.

To make 18 bags of snack mix, Sherry needs _ cups of almonds.

Sherry needs 6 cups of granola to make _ bags of the snack mix.

If Sherry uses 1 cup of cranberries, she will need to use _ cups of raisins.

The recipe will make _ bags of the snack mix if Sherry uses only 1 cup of granola.

Answers

Answer:

4.5 cups, 12 bags

Step-by-step explanation:

If she uses 6 cups of granola she is using twice as much so she could make 12 bags.

y = 3x + 6

Step-by-step explanation:

Since the line is parallel, it has the same slope -- 3

y = 3x + b, sub point (1, 9)

9 = 3(1) + b

9 = 3 + b

b = 9 - 3

b = 6

y = 3x + b -- y = 3x + 6

Answer is y=3x+6

The slope remains the same as it’s parallel. Then replace the x and y with the coordinates (1,9) —> 9=3(1)+b and solve for b. B will equal to 6 and you just put it in y=Mx+b format.
