Answer:

B.12 weeks

Step-by-step explanation:

Sam already has $50 dollars saved.

He wants to get $30 each week.

The cost is $410.

If he already has 50 you should subtract this from 410(it equals 360)

Then you multiply each answer by 30

The correct answer is B.12

30*12=360

(sorry if that is confusing my brain works weird)

In a family, each brother has as many sisters as brothers, but each sister has twice as many brothers as she has sisters. How ma

daser333 [38]

Answer:

4 brothers and 3 sisters

Step-by-step explanation:

Let x be the number of brothers and y be the number of sisters in the family.

1. Each brother has x-1 brothers and y sisters. If each brother has as many sisters as brothers, then

$x-1=y.$

2. Each sister has y-1 sisters and x brothers. If each sister has twice as many brothers as she has sisters, then

$2(y-1)=x.$

3. Solve the system of two equations:

$\left\{\begin{array}{l}x-1=y\\ \\2(y-1)=x\end{array}\right.\Rightarrow 2(y-1)-1=y,\\ \\2y-2-1=y,\\ \\2y-y=2+1,\\ \\y=3.$

Then

$x=y+1=3+1=4.$

A square has a diagonal length of 5 cm. The area of the squareiscm2. Round answer to the nearest tenths ifneeded.

Whitepunk [10]

$\begin{gathered} \text{Diagonal}=5\operatorname{cm} \\ \text{Area}=\frac{D^2}{2} \\ \\ \text{Area}=\frac{(5cm)^2}{2} \\ \\ \text{Area}=\frac{25\operatorname{cm}^2}{2} \\ \\ \text{Area}=12.5\operatorname{cm}^2 \\ \text{The area of the square is 12.5 cm }^2 \end{gathered}$

Solve the system of linear equations. 3x−2y=1 9x−6y=3

irakobra [83]

Get the y by itself

-2y= -3x + 1

Divide -2 to everything

y= 3/2x - 1/2

Other equation (get y by itself)

-6y= -9x + 3
y=3/2x - 1/2

Use substitution

3/2x-1/2=3/2-1/2

0=0

All real numbers (any value of x makes the equation true)
