One fifth of a number plus three times the number is equal to 42 Moré than twice the number. Whats the number
riadik2000 [5.3K]

Answer:

35

Step-by-step explanation:

Let number = x

(1/5 of x) + (3 * x) = 42 + (2 * x)

x/5 + 3x = 42 + 2x

1/5x + 3x - 2x = 42

1 1/5x = 42

6/5 x = 42

x = 42 ÷ 6/5

x = 42 * 5/6

x = 210 / 6

x = 35

The number is 35

The figure shows trapezoid ABCD on a coordinate plane.
docker41 [41]

Answer:

121 unit^2.

Step-by-step explanation:

The area = height/2 * ( sum of the opposite parallel  lines)

= h/2(BC + AD

h = BF = 14 - 3 = 11 units.

BC   = 13 - 5 = 8 units.

AD = 16 - 2 = 14 units.

Area = (11/2)(8 + 14)

= 5.5 * 22

= 121 unit^2.

What is the general form of the equation of a circle with center at (a, b) and radius of length m?. A. x2 + y2 − 2ax − 2by + (a2
drek231 [11]
\bf \textit{equation of a circle}\\\\ 
(x- h)^2+(y- k)^2= r^2
\qquad 
center~~(\stackrel{a}{ h},\stackrel{b}{ k})\qquad \qquad 
radius=\stackrel{m}{ r}
\\\\\\
\boxed{(x-a)^2+(y-b)^2=m^2}\\\\
-------------------------------\\\\
(x^2-2ax+a^2)+(y^2-2yb+b^2)=m^2
\\\\\\
x^2-2ax+a^2+y^2-2yb+b^2-m^2=0
\\\\\\
x^2+y^2-2ax-2yb+(a^2+b^2-m^2)=0
