if DF=78, DE=5x-9, and EF=2x+10 Find EF
Answer:
EF = 32
Step-by-step explanation:
DE + EF = DF
5x - 9 + 2x + 10 = 78
5x + 2x + 10 - 9= 78
7x + 1 = 78
7x = 78 - 1
7x = 77
x = 77/7
x = 11
[tex]EF=2x+10 = 2 \times 11 + 10 \\ EF=22 + 10 \\ \huge \red { \boxed{EF=32}}[/tex]
Express using algebra: The number that is b less than 10
Answer:
x=b-10
Step-by-step explanation:
any is in a word problem means = and less than means subtract. I am only 90% sure this answer is correct but using my logic this is what I got.
The number that is b less than 10 will be given in the mathematical form as n = b - 10.
What is the value of the expression?When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Express using algebra: The number that is b less than 10. Let the number be n. Then the equation is given as,
n = b - 10
The number that is b less than 10 will be given in the mathematical form as n = b - 10.

If EC bisects BED, find m BED.
A. 128°
B. 130°
C. 134°
D. 136°
Answer:
19x+22
Step-by-step explanation:
Answer:
D. 136°
Step-by-step explanation:
[tex]\because \overrightarrow{EC} \:bisects \: \angle BED. \\
\therefore m\angle BEC = m\angle DEC\\
\therefore (11x+2)\degree = (8x+20)\degree \\
\therefore 11x + 2 = 8x + 20\\
\therefore 11x - 8x = 20-2\\
\therefore 3x = 18\\
\therefore x = \frac{18}{3}\\
\therefore x = 6\\\\
\because m\angle BED= m\angle BEC + m\angle DEC\\
\therefore m\angle BED= (11x+2)\degree + (8x+20)\degree\\
\therefore m\angle BED= (19x+22)\degree \\
\therefore m\angle BED= (19\times 6+22)\degree \\
\therefore m\angle BED= (114+22)\degree \\
\huge \purple {\boxed {\therefore m\angle BED= 136\degree}} \\[/tex]

what is the solution for x in 12x-4=5x+24
Answer:
x = 4Step-by-step explanation:
12x - 4 = 5x + 24
First subtract 5x from both sides
That's
12x - 5x - 4 = 5x - 5x + 24
7x - 4 = 24
Add 4 to both sides
That's
7x - 4 + 4 = 24 + 4
7x = 28
Divide both sides by 7
We have the final answer as
x = 4Hope this helps you
Answer:4
Step-by-step explanation:First, add 4 to both sides of the equation. Then subtract 5x from both sides. Finally, divide both sides by 7.
