Solve the proportion<br>17/3 = y/6
cricket20 [7]
To solve a proportion, you can either use cross products or basic multiplication.

To do cross products, you would multiply 17 (1st numerator) by 6 (2nd denominator). 

Do the same with the other diagonal angle, 3 times y.

You'll end up with 3y = 102.

To solve for y, you divide both sides by 3.

102 ÷ 3 = 34

y = 34

The other way you could solve this is to see that 6 is 2 times as large as 3, so you would multiply 17 by 2 to get an equal proportion.

3 × 2 = 6
17 × 2 = 34

Your final answer is y = 34. Hope this helps! :)

MAVERICK [17]

Answer:

the simplest form of the given expression is -1\frac{4}{35}

Step-by-step explanation:

Given;

2 \times  \frac{1}{7}  -  1\frac{2}{5}

The above expression can be simplified as follows;

2 \times  \frac{1}{7}  -  1\frac{2}{5} \\\\=\frac{2}{7} - \frac{7}{5} \\\\= l.c.m \ of \ 7 \ and \ 5 \ is \ 35\\\\= \frac{5(2) - 7(7)}{35} \\\\= \frac{10 - 49}{35} \\\\= -\frac{39}{35} \\\\= - 1\frac{4}{35}

Therefore, the simplest form of the given expression is -1\frac{4}{35}

Event A has a 0.3 probability of occurring and event B has a 0.4 probability of occurring. A and B are independent events. What
Ipatiy [6.2K]
There is a 99.3 chance that neither occur cause you would add 0.3 and 0.4 together and get 0.7 then you would subtract 100 and 0.7 and get 99.3. So your answer is 99.3. Hope this helped :D
