Brittany is asked about her age. She answers as follows. "My age is 10 more than twice the age of my younger brother." How old i

blagie [28]

Answer:

Step-by-step explanation:

x will be the age of her younger brother

34 = 2x + 10

She is ten more than twice his age

34 = 2x + 10

- 10 - 10

Then she twice his age

24 = 2x

÷2 ÷2

So his age is 12

x = 12

Help!!!!!!!!!!!!!!!!!!!!

Well... the segment FG = 4x + 3, the segment GH = 7x - 12, now, the

segment FH = FG + GH, those two fellows added up, and we know that FG and GH are both equal halves because G is the midpoint.

thus, FG = GH
or

$\bf 4x+3=7x-12\implies 3+12=7x-4x\implies 15=3x
\\\\\\
\cfrac{15}{3}=x\implies \boxed{5=x}\\\\
-------------------------------\\\\
thus\qquad 
\begin{cases}
\overline{FG}=4x+3\\
4(5)+3\\
23\\
------\\
\overline{GH}=7x-12\\
7(5)-12\\
23
\end{cases}\impliedby equal\ halves
\\\\\\
\overline{FH}=23+23\implies \overline{FH}=46\implies 6y-2=46
\\\\\\
6y=46+2\implies y=\cfrac{48}{6}$

and fairly sure, you know how much that is.

Write an expression to represent the sum of three consecutive even numbers. Let C represent the first number in the series

Anna [14]

Let, the first number = C
second number will be = C + 2 ['cause next will be odd so we can't include that]
Third number = C + 4

Now, their sum would be:
C + C+2 + C+4 = 3C + 6

In short, Your Answer would be 3C + 6

Hope this helps!
