Answer: Boys = 1024

Girls = 972

Step-by-step explanation:

Let the number of boys = x ...... ( 1 )

Therefore the number of girls = x - 52 ..…... (2 ) ( x < 52 )

X + x - 52 = 1996

2x - 52 = 1996

2x = 1996 + 52

2x = 2048

X = 2048/2

X = 1024

Substitute for x in equation ...( 2 ) to get the number of girls

1024 - 52 = 972

Now , number of boys = 1024

And number of girls = 972

What is the value of y? Y Y 60 O A. 120° B. 60° C. 40° O D. 30°

Grace [21]

Answer:

B. 60°

Step-by-step explanation:

1. The measure of all angles in a triangle sum up to 180°. This means that y + y + 60 = 120.

2. (Solving)

Step 1: Simplify both sides of the equation.

$(y+y)+(60)=180$
$2y + 60 = 180$

Step 2: Subtract 60 from both sides.

$2y + 60 - 60 = 180 - 60$
$2y = 120$

Step 3: Divide both sides by 2.

$\frac{2y}{2}=\frac{120}{2}$
$y = 60$

Step 4: Check if solution is correct.

$(60)+(60)+60 = 180$
$120 + 60 = 180$
$180 = 180$

Therefore, the answer is B. 60°.

A system of linear equations is graphed. Which ordered pair is the best estimate for the solution to the system? (12, 0) (1, 1)

GuDViN [60]

Line 1--------- >(0,2) (1,-1)
y=mx+b m=(-1-2)/(1-0)=-3
2=(-3)*(0)+b----- > b=2
y1=-3x+2

Line 2--------- >(0,-1) (2,2)
y=mx+b m=(2+1)/(2-0)=3/2
-1=(3/2)*(0)+b----- > b=-1
y2=(3/2)x-1

using a graphic tool
see attached figure

the best estimate solution for the system is (1, 1)
because is the only one within the range of the x axis (-5,5) and the y axis (-5,5)
