Answer:

x= 42

y= 23

Step-by-step explanation:

Set up a system of equations like this:

(4y-9)=(3x-43)

(2x+13)=(4y+5)

when two lines cross like this they form vertical angles, and vertical angles are always equal.

calculate the system of equations and you'll get x=42 and y=23

To find the measure of any of the angles just put x or y into the equation.

Help pls! simplify -6 x^{2} ÷ 12 - 2(-7) a. -17 b. 35 c. -35 d. 11

Mariana [72]

Answer:

Step-by-step explanation:

Given: $\frac{-6^{2}}{12} -2(-7)$

Using PEDMAS rule to solve it.

Now, simplifying:

We first open parenthesis which is (-7) = -7

= $\frac{-6^2}{12}-2\times -7$

Now, we evaluate the exponent which is $-6^2=-36$

Next, we divide -36 by 12 to get -3

= $\frac{-36}{12}-2\times -7 \\= -3 -2\times -7$

Next, we multiply -2 and -7 to get 14

= $-3 + 14$

Lastly, we add -3 and 14 to get 11

= $11$

∴ Answer is 11

Which ratio is equivalent to 3/7? A) 6 to 10 B) 9:12 C) 12/35 D) 7 to 3

Leona [35]

we are ratio as

$=\frac{3}{7}$

It will be equivalent to only those terms which would be multiple of this term

so, we will multiply top and bottom term by 5

and we get

$=\frac{3\times 5}{7\times 5}$

$=\frac{15}{7\times 5}$

$=\frac{15}{35}$

so, it is very similar to 12/35

so, it will be equivalent to 12/35

so, option-C.......Answer
