Which of the following is the solution to the system of equations?

drek231 [11]

Answer:

B (3/4,5/4)

Step-by-step explanation:

y = 2- x

$\frac{5}{4} = 2 - \frac{3}{4}$

y = 3x - 1

$\frac{5}{4} = 3 \times \frac{3}{4} - 1$

$\frac{5}{4} = \frac{9}{4} - \frac{4}{4}$

Hope this helps ^-^

How many 5 digit numbers have the property that all their digits are ascending.

sertanlavr [38]

Answer:

So, for the ascending order, there are only 9 digits to choose from, and hence, there are 9C5 ways to choose the 5 digits. So, there can be 9C5=126 5-digit no.s with their digits in an ascending order.

There are 10 marbles in a bag. Four are blue, 3 are black and 2 white and 1 red. If the marbles are not replaced once they are d

stich3 [128]

Given:

Given that there are 10 marbles in a bag. 4 are blue, 3 are black, 2 are white and 1 is red.

The marbles are selected by not replacing the drawn ones.

We need to the probability of selected a black marble and then a white marble without replacement.

Probability:

Let B denote the black marble.

Let W denote the white marble.

The probability of selecting a black marble is $P(B)=\frac{3}{10}$

The probability of selecting a white marble without replacement is $P(W)=\frac{2}{9}$

The probability of selecting a black marble and then a white marble without replacement is given by

$P(B \ and \ W)=P(B) \cdot P(W)$

Substituting the values, we get;

$P(B \ and \ W)=\frac{3}{10} \cdot \frac{2}{9}$

$P(B \ and \ W)=\frac{6}{90}$

$P(B \ and \ W)=\frac{1}{15}$

Thus, the probability of selecting a black marble and then a white marble without replacement is $\frac{1}{15}$

Any help?? I’ve tried this for a hour and couldn’t figure anything out

Effectus [21]

Answer:

3. PR=51

4. FE=28

Step-by-step explanation:

3. since the two triangles are similar, set up a proportion:

x+8/3x-9=24/28

*cross multiply*:

28(x+8)=24(3x-9)

28x+224=72x-216

44x=440

x=20

to find PR:

PR=3x-9

PR=3(20)-9

PR=51

4. same here:

39/4x+2=42/5x-2

39(5x-2)=42(4x+2)

195x-78=168x+84

27x=162

x=6

to find FE:

FE=5x-2

FE=5(6)-2

FE=28

Andy wrote the following statement:

olasank [31]

I believe it would be B. Because, an isoceles triangle is a triangle with 2 equal sides and 1 is not equal ... SO, more than one triangle could be drawn from this information. Because, 55 could be the uneven side for many triangles. So, B. Andy is incorrect, because more than one triangle can be drawn from the given info. :)

B. Hope it helps!!! :)
