Answer:
175°
Step-by-step explanation:
Since, [tex] \overrightarrow{BD} [/tex] is in the interior of [tex] \angle ABC[/tex]
[tex] \therefore m\angle ABC = m\angle ABD + m\angle CBD\\
\therefore (14x + 21)\degree = (2x + 3)\degree + 150\degree \\
\therefore (14x + 21)\degree = (2x + 153)\degree\\
\therefore 14x + 21 = 2x + 153\\
\therefore 14x - 2x = 153 - 21\\
\therefore 12x = 132\\
\therefore x = \frac{132}{12}\\
\therefore x = 11\\\\
m\angle ABC = (14x + 21)\degree\\
m\angle ABC = (14\times 11+ 21)\degree\\
m\angle ABC = (154+ 21)\degree\\
\huge\red {\boxed {m\angle ABC = 175\degree}} \\[/tex]

Answer:
∠B = 156°
Step-by-step explanation:
A line intersects two parallel lines this means that their opposite angles are transversals specifically the angles, A and B. And transversal angles are congruent so I can make this claim below:
[tex]∠A = ∠B \\ 8x +78 = 2x +144[/tex]
Solving for x:
[tex]8x +78 = 2x +144 \\ 8x -2x +78 = 2x -2x +144 \\ 6x +78 -78 = 144 -78 \\ 6x = 66 \\ \frac{6x}{6} = \frac{66}{6} \\ x = 11[/tex]
Solving Angle B if x = 11.
[tex]∠B = 2x +144 \\ ∠B = 2(11) +144 \\ ∠B = 22 +144 \\ ∠B = 166[/tex]
which value for x makes the sentence true? 1/40 + x = 1/8
Answers
Answer:
x = 1/10
Step-by-step explanation:
1/40 + x = 1/8
Subtract 1/40 from each side
1/40-1/40 + x = 1/8-1/40
x = 1/8 - 1/40
Get a common denominator
x = 1/8 *5/5 - 1/40
x = 5/40 - 1/40
x = 4/40
Simplify
x = 1/10

f(g(x)) = 3(x-2) + 10
f(g(0)) = 3x - 6 + 10
f(g(0)) = 3(0) - 6 + 10
f(g(0)) = 0 - 6 + 10

Savannah's balance in her checking account was –$638.57. She deposited two checks, each in the amount of $298.40. What is Savannah’s new checking account balance after the deposits?
Answers
Answer:
$-41.77
Step-by-step explanation:
$298.40 multiplied by 2 is $596.8, since Savannah added 2 deposits.
Now we add that to the current balance, -$638.57, to get an answer of $-41.77
Answer:
-41.77
Step-by-step explanation:
Multiply $298.40 by 2 OR add $298.40 + $298.40
either gives you $596.80
Savannah deposited $596.80
You add that to -$638.57

Add like terms
Step-by-step explanation:
You want to combine the squared, the variables, and the constants.
Combine -2x^2 and 7x^2 to get 5x^2
Then combine 8x and 4x which is 12x
Then combine -9 and +2 which is -7.
You should get 5x^2 + 12x - 7.
Keep in mind you can only combine like terms that are in the same equals barrier
For example: You can combine 8x + 3 + 2x = 0
but not 8x +3 = 2x +0 because they are on different sides of the equal sign.
