Answer:

Step-by-step explanation:

5(a-1) -15 = 3(a+2) +4, distribute multiplication over subtraction and addition

5a -5 -15 = 3a +6 + 4, isolate the variable on one side

5a -3a = 6 +4 +5 +15, combine like terms

2a = 30, divide both sides by 2

a= 15

What is the probability of drawing an even numbered card, keeping it, and then drawing another even numbered card from a stack o

Oksanka [162]

Answer: 1/4

Step-by-step explanation:

In a stack of 24, the 2 mediums are odd and even cards in this question. This means that 1/2 the cards are even and 1/2 are odd. To get a even card once is a 1/2 chance, then to get it again is 1/2 x 1/2 chance or 1/4 chance. This is what I think.

Alvin takes pictures with his smartphone. Of the pictures 5/6 are animals. 3/4 of the animals are dogs. What fraction of the pic

ollegr [7]

Answer:

$\dfrac{5}{8}$

Step-by-step explanation:

Alvin takes pictures with his smartphone.

Of the pictures $\frac{5}{6}$ are animals.

$\frac{3}{4}$ of the animals are dogs.

To find which fraction of all pictures are pictures with dogs, you can simply multiply two fractions:

$\dfrac{5}{6} \times \dfrac{3}{4} =\dfrac{15}{24} =\dfrac{5}{8}$

<u>Another way</u> to solve this question:

Let the number of all pictures be 24 (divisible by both 4 and 6).

Then the number of pictures with animals is

$\dfrac{5}{6} \times 24=5\times 4=20$

and the number of pictures with dogs is

$\dfrac{3}{4} \times 20=3\times 15$

Hence, the fraction of pictures with dogs of all pictures is

$\dfrac{15}{24}=\dfrac{5}{8}$
