Answer:
The unknown angle = 126°
Step-by-step explanation:
From angles in a triangle.
The total sum of angles in a triangle = 180°
Let the unknown angle be x
27 + 27 + x = 180
X = 180-27-27
X= 180-54
X = 126°
Answer:
Step-by-step explanation:
Let b represent the number of black
ink pens that John wants to buy.
Let r represent the number of red
ink pens that John wants to buy.
John wishes to buy 20 pens. This would be expressed as
b + r = 20
The store sells black ink pens for $5 and red ink pens for $4. John doesn’t wish to spend more than $92. The inequality to show this information would be expressed as
5b + 4r ≤ 92
Answer:
Ten thousandths
Step-by-step explanation:
The 4 is in the ones place, so the 5 is in the tenths, the 0 in the hundredths, the 1 in the thousandths, so the 2 is in the ten thousandths.
Answer:
i'm SORRY but where is the linear model
Step-by-step explanation:
Answer:
Step-by-step explanation:
complete the square:
Take a quadratic equation : ax²+bx+c and turn it to
a(x+d)²+e
d=b/2a and e=c-b²/4a
y=x^2 - 14x + 48
a=1 , b=-14 , c=48
d=-14/2=-7
e= 48-14²/4
e= 48-49
e=-1
complete the square for y=x²-14x+48
y= (x-7)²-1
