a = 2x + 6xz

a = x(2 + 6z) <em>factored out "x" on right side</em>

a/(2 + 6z) = x <em>divided both sides by (2 + 6z)</em>

Answer: x = $\frac{a}{2 + 6z}$

What is the length of the hypotenuse for a right triangle with legs of length 9 and 40?

Step2247 [10]

Answer:

$c = 41$

Step-by-step explanation:

${c}^{2} = \sqrt{ {a}^{2} + {b}^{2} }$

$c = \sqrt{ {a}^{2} + {b}^{2} }$

$c = \sqrt{ {9}^{2} + {40}^{2} }$

$c = \sqrt{81 + 1600}$

$c = \sqrt{1681}$

$c = 41$

Johanna has to solve the system of equations using substitution. She isolates x in the second equation. Which should be her next

olganol [36]

Answer: A) 3(10 - 5y) + 6y =12

Step-by-step explanation:

As per the question , the given system of linear equation :

$3x+6y=12---(i)\\\\ x+5y=10---(ii)$

Here , To solve the system of equations using substitution , Johanna isolates x in the second equation and writes

$x=10-5y$

As per the substitution method , the next step is to substitute the isolated value of 'x' in first equation , thus the next step will become

$3(10-5y)+6y=12$

Hence, the correct option is A) 3(10 - 5y) + 6y =12
