Answer:

y = 5 − 2x

4x + 2y = 10

(Infinite solutions)

x = 26 − 3y

2x + 6y = 22

(No solution)

5x + 4y = 6

10x − 2y = 7

(Single solution)

x + 2y = 3

4x + 8y = 15

(No solution)

3x + 4y = 17

-6x = 10y − 39

(Single solution)

x + 5y = 24

5x = 12 − y

(Single solution)

There are 7 cherries and 3 grapes in a bag. What is the pobability of selecting 2 grapes at random without replacement?
dlinn [17]

Answer:

1/15

Step-by-step explanation:

7+3 = 10 items in the bag

P(grape) = grapes/total

                3/10

No replacement

7 cherries 2 grapes = 9 items

P(grape) =  grapes/total

                    2/9

P(grape, no replacement, grape) = 3/10*2/9

                                                       =1/15

Answer it pls option c
Troyanec [42]

Answer:

x = \frac{1}{4}

Step-by-step explanation:

\frac{x}{2} +\frac{3}{4} =\frac{7}{8}

→ Find the LCM of the denominators (2,4 and 8)

LCM = 8

→ Multiply the whole equation by 8 to get rid of the fractions

4x + 6 = 7

→ Minus 6 from both sides to isolate 4x

4x = 1

→ Divide both sides by 4 to isolate x

x = \frac{1}{4}
