Answer:
∴ x= 17
Step-by-step explanation:
the total of angel in 90°
∴ 2x+3+3x+2 =90
∴ 5x +5 =90
5x=90-5
5x = 85 (divide both side by 5)
∴ x= 17
Lets get started :)
2 + 2 + x - 7 = 21
11 + x = 21
We have to subtract 11 on both sides to isolate x
11 ( - 11 ) + x = 21 ( - 11 )
11 and 11 cancels out
x = 10
Answer:
five and eight hundredths
Step-by-step explanation:
I was taught to reserve the word "and" to mark the decimal point when the number has a fraction. The integer part is "five." The fractional part is "eight hundredths." Together, the word form might be ...
five and eight hundredths.
__
If I were reading this to someone, including myself, I might say it as ...
"five point oh eight".
_____
<em>Comment on ambiguity</em>
The reason for being particular about marking the decimal point is so you don't get into trouble with something like ...
1000.13 . . . . . one-thousand and thirteen hundredths
which is different from ...
1013/100 . . . . one-thousand thirteen hundredths
Some folks will pronounce 1013 as "one-thousand and thirteen." Doing so will get you in trouble in the above situation, where you have 1013/100.

Answer:
y = - 3x + 11
Step-by-step explanation:
the altitude is a line from the vertex A drawn perpendicular to the opposite side BC
calculate the slope of BC using the slope formula
m = 
with (x₁, y₁ ) = B (- 7, 3 ) and (x₂, y₂ ) = C (- 1, 5 )
= 
= 
= 
= 
given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= - 3
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept ) , then
y = - 3x + c ← is the partial equation
to find c substitute A (4, - 1 ) into the partial equation
- 1 = - 12 + c ⇒ c = - 1 + 12 = 11
y = - 3x + 11 ← equation of altitude from A
