Answer:

I believe it would be the 3rd answer.

Step-by-step explanation:

That answer is the only one where not only do one of the systems have that point but they both do. That is where they intercept. Plus when you fit in the x and y points in the equations they match up. Hope that helps!

Answer:

1) $x=\dfrac12$

2) $n = -3 \ \ \textsf{and} \ \ m = -4$

3) see below

4) A: 0 = 1

Step-by-step explanation:

<u>Question 1</u>

$15-0.5(4x-2)+4x=17$

$\implies 15-2x+1+4x=17$

$\implies 2x+16=17$

$\implies 2x=1$

$\implies x=\dfrac12$

<u>Question 2</u>

$\textsf{rearrange} \ n=m+1 :$

$\implies -m=-n+1$

$\textsf{add equations} \ -m=-n+1 \ \textsf{and} \ m=2n+2:\\$

$\implies0=n+3$

$\implies n=-3$

$\textsf{substitute} \ \ n=-3 \ \ \textsf{into} \ \ m=n-1:$

$\implies m=-3-1$

$\implies m=-4$

<u>Question 3</u>

subtract the second equation from the first

divide both sides by -4

substitute found value for y into first equation

solve for x

<u>Question 4</u>

$3j=k$

$k=3j+1$

$\textsf{rearrange} \ 3j=k :$

$\implies -k=-3j$

$\textsf{add equations}\ -k=-3j \ \ \textsf{and}\ \ k=3j+1:$

$\implies 0=1$

Solution = A

Noel has rowing lessons every 5 days and guitar lessons every 6 days. If he had both lessons on the last day of the previous mon

bixtya [17]

Answer:

Since every 30 days he wil have both lessons on the same day , and he already had both lessons on the last day of the previous month, that means that the day 30 the current month he wil have both lessons on the same day (It may be the last day if the month has 30 days or it may not be the last day if the month has 31 days)

Step-by-step explanation:

Lets find the least common factor of 5 and 6

Multiples of 5

5 10 15 20 35 30 35 40......

Multiples of 6

6 12 18 24 30 36

LCF of 5 and 6 = 30

Every 30 days he wil have both lessons on the same day

Area of square = 135 mm²<br> Perimeter of square=

11Alexandr11 [23.1K]

Answer:

About 11.62 by 11.62

A square had equal sides so you find the square root of 135 and that is rounded to 11.62.

So the perimeter would be about 46. But 46.48 exactly.

Aysha has 40 cubes in a bag.

marissa [1.9K]

Given:

Total number of cubes = 40

Red cubes = 18

Blue cubes = 13

Yellow cubes = 9

Aysha adds some more red cubes into the bag.

The probability now that she will take a red cube is 0.5.

To find:

The probability that she will take a yellow cube.

Solution:

Let Aysha adds x red cubes into the bag. Then,

Number of total cubes = 40+x

Number of red cubes = 18+x

Probability of getting a red cube is:

$P(Red)=\dfrac{18+x}{40+x}$

The probability now that she will take a red cube is 0.5. So,

$\dfrac{18+x}{40+x}=0.5$

$18+x=0.5(40+x)$

$18+x=20+0.5x$

$x-0.5x=20-18$

$0.5x=2$

Divide both sides by 0.5.

$x=\dfrac{2}{0.5}$

$x=4$

It means Aysha adds 4 more red cubes into the bag.

Now, the total number of cubes int he bag is:

$40+4=44$

Probability of getting a yellow cube is:

$P(Yellow)=\dfrac{\text{Number of yellow cubes}}{\text{Total number of cubes}}$

$P(Yellow)=\dfrac{9}{44}$

Therefore, the required probability is $P(Yellow)=\dfrac{9}{44}$ .
