The figure is a parallelogram.<br> Solve for x.
lions [1.4K]

Answer:

x = 7

Step-by-step explanation:

Adjacent angles of a parallelogram are supplementary.

\therefore \: (14x + 2) \degree + 80 \degree = 180 \degree  \\  \\  \therefore \: (14x + 2) \degree = 180 \degree   - 80 \degree \\  \\ \therefore \: (14x + 2) \degree = 100 \degree \\  \\ 14x + 2 = 100 \\ 14x = 100 - 2 \\  \\ 14x = 98 \\  \\ x =  \frac{98}{14}  \\  \\ x = 7

If 0.142857142857......is expressed in the form m/n, then what is the value<br>of (2m + n)?​
frosja888 [35]

Answer:

The value will be: 1,285,713

Step-by-step explanation:

We have the number:

N = 0.142857...

Such that we have 6 decimals after the decimal point that repeat infinitely.

Then let's start by multiplying our number by 1,000,000 (same number of zeros as decimals after the decimal point)

Then we get:

1,000,000*N = 142,857.142857...

Now let's subtract N from both sides:

1,000,000*N - N =  142,857.142857... - 0.142857...

999,999*N = 142,857

Now let's isolate N

N = 142,857/999,999

Here is our number expressed in the form m/n, where:

m = 142,857

n = 999,999

Then the value of (2*m + n) is:

(2*142,857 + 999,999) = 1,285,713

What is the length x of PQ
Bas_tet [7]

Answer:

11.2

Step-by-step explanation:

If the rectangulars are similar then we can use similarity ratio to calculate value of x

CD is similar to RS and AB is similar to QP

4/6.4 = 7/x cross multiply expressions

4x = 44.8 divide both sides by 4

x = 11.2
