Answer:

Kaleb took the additive inverse of the first integer.

Step-by-step explanation:

The subtraction: 6 - 17, can be changed to: 6 + (-17), adding the additive inverse (the minus sign of the subtraction changes to a plus sign, and 17 changes to its additive inverse, -17).

Kaleb transforms: 6 - 17, into: -6 + 17. He took the additive inverse of the first integer, instead of the second one.

The equation representing this situation is 25 + 5x = 40, where x represents the price of each pair of socks.

To determine the price of each pair of socks, we can set up an equation based on the given information.

Let's assume that the price of each pair of socks is represented by x.

Andrea bought 5 identical pairs of socks, so the total cost of the socks is 5x.

Additionally, she bought a pair of shoes for $25.

Considering the total amount spent at the shoe store is $40, we can write the equation as follows:

25 + 5x = 40.

This equation represents the total cost of the shoes and socks equaling the amount Andrea spent.

To find the price of each pair of socks, we solve the equation for x.

First, subtract 25 from both sides:

5x = 40 - 25,

5x = 15.

Then, divide both sides by 5 to isolate x:

x = 15 / 5,

x = 3.

Therefore, each pair of socks costs $3.

The length of the hypotenuse in the given triangle is A. 15 units.

This type of question makes a right-angled triangle that can be solved by Pythagoras's theorem.

In a right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.

Given, the base of the triangle is 12 units and the height is 9 units.

∴ x² = 9² + 12².

x² = 144 + 81.

x² = 225.

x = + 15 units.

So, the length of the hypotenuse is 15 units.

Answer:

n = 18 cycles

Step-by-step explanation:

To know how many times does the current oscillates in the given time, you take into account that the number of oscillation can be calculated by using the following expression:

[tex]n=ft[/tex]         (1)

f: frequency of the oscillation of the current

t: time = 0.30s

The frequency is the number of cycles per second, that is, f = 60 cycles/s

You replace the values of f and t in the equation (1):

[tex]n=(60\frac{cycles}{s})(0.30s)=18\ cycles[/tex]

In 0.30s the current oscillates 18 times

Solution of the system of equations will be (6, 6).

Step-by-step explanation:

Table for the first equation,

[tex]y=\frac{1}{2}x+3[/tex]

x          0          2         4         6         8      

y          3          4         5         6         7

(x, y) (0, 3)    (2, 4)   (4, 5)    (6, 6)   (8, 7)

We have got the values of y by substituting the values of x in the given equation for the table.

Similarly, for the other equation,

y = 2x - 6

x           0          2         4           6           8

y          -6         -2         2           6          10  

(x, y)  (0, -6)   (2, -2)  (4, 2)   (6, 6)    (8, 10)

By analyzing both the tables we find (6, 6) is a common point in both the tables.

That represents the points of intersection of both the lines.

Therefore, solution of the system of equations will be (6, 6)

Answer:

The correct option is:

The graph passes through the point (0, 4), and for each increase of 1 in the x-values, the y-values increase by a factor of 1.5.

Step-by-step explanation:

The function given to us is:

f(x) = 4(1.5)ˣ

Substitute x = 0 in the given function:

f(0) = 4(1.5)⁰

f(0) = 4(1)

f(0) = 4

Which means that the graph pass through the point (0,4)

Now Substitute x = 1 in the given function:

f(1) = 4(1.5)¹

f(1) = 6

Substitute x =2 in the given function:

f(2) = 4(1.5)²

f(2) = 9

Divide the consecutive values:

f(2) / f(1) = 9/6 = 1.5

f(1) / f(0) = 6/4 = 1.5

Hence the values of y increase by the factor of 1.5

Answer:

B The graph passes through the point (0, 4), and for each increase of 1 in the x-values, the y-values increase by a factor of 1.5.

So all I did was go through trial and error and I went and saw what 20% of number like 450 and 420 were and then I added them to the price to see if it would get to £480. So when I checked 20 percent of 400 I got 80 which added to 400 gives the market price of £480.

Answer: 65 grams

Step-by-step explanation:

If 130 grams of a gold alloy (a mixture of gold and one or more other metals) containing 85% pure gold, that means the percentage of other metals will be;

100 - 85 = 15 %

You should first calculate the amount of gold that makes up this percentage.

That is, 85% of 130 grams.

85/100 × 130 = 110.5

Then, let X be what will be added to the above value to make 90%. So,

(110.5 + X) / ( 130 + X ) × 100 = 90

Divide both sides by 100

(110.5 + X) / ( 130 + X ) = 90/100

(110.5 + X) / ( 130 + X ) = 0.9

Cross multiply and open the bracket

110.5 + X = 117 + 0.9X

Collect the like terms

X - 0.9X = 117 - 110.5

0.1X = 6.5

Divide both sides by 0.1

X = 6.5/0.1

X = 65 grams

Therefore, the amount of pure gold that should be added is 65 grams
