Answer: The original number was 18.25 or 18 1/4
18.25 plus 6 is 24.25
24.25 times 2 is 48.5
Step-by-step explanation:
mark as brilliant answer
F(x)=ax^2+4 thus
a=(f(x)-4)/x^2=(5-4)/(-1)^2=1
Answer: a=1.
Answer:
x =8
The angles are
3x= 24
7x+4 = 60
13x-8 =96
Step-by-step explanation:
The sum of the angles of the triangle is 180
3x+ 7x+4 + 13x-8 =180
Combine like terms
23x -4 = 180
Add 4 to each side
23x -4+4 =180+4
23x =184
Divide by 23
23x/23 = 184/23
x =8
The angles are
3x= 3*8 =24
7x+4 = 7*8+4 = 56+4 = 60
13x-8 = 13*8-8 =104-8=96
Answer:
400 yd
Step-by-step explanation:
There are 2 ft of ribbon for 1 doll.
For 600 dolls,
Ribbon = 600 × 2/1
Ribbon = 1200 ft
=====
Convert feet to yards
1 yd = 3 ft
Ribbon = 1200 × 1/3
Ribbon = 400 yd
