Since those are consecutive interior angles, we can conclude:

$\begin{gathered} 4x+6x=180 \\ _{\text{ }}add_{\text{ }}like_{\text{ }}terms\colon \\ 10x=180 \\ _{\text{ }}solve_{\text{ }}for_{\text{ }}x\colon \\ \frac{10x}{10}=\frac{180}{10} \\ x=18 \end{gathered}$

If 4 : 9 is equivalent to (5x+13) : 63, then what is the value of x?

Aleksandr [31]

$\large{\underline{\underline{\pmb{\sf{\color{yellow}{Answer:}}}}}}$

The value of x is 3

Step-by-step explanation:

$\textsf{\underline{\large{To find :-}}}$

The value of x

$\textsf{\underline{\large{Given :-}}}$

4 : 9 = (5x + 13) : 63

$\textsf{\underline{\underline{\large{Solution :-}}}}$

we can write this as

$\sf \frac{4}{9} = \frac{(5x + 13)}{63}$

Now we will cross multiply the values

$\sf 4 \times 63 = 9(5x + 13) \\ \\ \sf 252 = 45x + 117 \\ \\ \sf 252 - 117 = 45x \\ \\ \sf 135 = 45x \\ \\ \sf \frac{135}{45} = x \\ \\ \sf \orange {3 = x}$

When I multiply 9x9 how would I go about counting by 9s?

11111nata11111 [884]

Answer:

If you're looking for a shortcut, I usually find the number 1 less than what you are multiplying 9 by, this case 8, and then add a number that gets to 9.

So 9x6 would be:

5+4=9

Step-by-step explanation:

When multiplying by 9s the product's two numbers added together =9.

Sorry if this is confusing. Hope this helps though.
