Amanda [17]
X=number of boys.
y=number of girls.
we suggest this system of equation
x/y=9/7
x=y+116
We solve this system of equation by substitution method.
(y+116)/y=9/7
7(y+116)=9y
7y+812=9y
9y-7y=812
2y=812
y=812/2=406

x=y+116
x=406+116=522

answer: At the school there are 522 boys and 406 girls.

to chek.
522/406=1.2857...
9/7=1.2857...

The number of boys (522) is equal to 406+116=522.

Roy and Sam start solving the equation as follows.
denpristay [2]

Answer:

The correct option is D.

Step-by-step explanation:

The given equation is

-3x+4=5x-6

According to the addition property of equality a=b and a+c=b+c are equivalent equations.

Use addition property of equality, add 3x on both the sides.

-3x+4+3x=5x-6+3x

4=8x-6

Therefore Sam's work is incorrect because he make calculation mistake.

According to the subtraction property of equality a=b and a-c=b-c are equivalent equations.

Use subtraction property of equality, subtract 5x from both the sides.

-3x+4-5x=5x-6-5x

-8x+4=-6

Therefore Roy's work is correct because he used subtraction property.

Option D is correct.

Find the total perimeter of the kite shown below. round to the nearest tenth . pleas use step by step instructions.
guapka [62]

Answer: B. 25.2 units

Step-by-step explanation:

The kite consists of 4 right angle triangles. The two smaller right angles are equal. Also, the two bigger right angles are equal.

To determine the hypotenuse of each triangle, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Considering the smaller triangle,

Hypotenuse² = 4² + 3² = 16 + 9 = 25

Hypotenuse = √25 = 5

Considering the smaller triangle,

Hypotenuse² = 7² + 3² = 49 + 9 = 58

Hypotenuse = √58 = 7.616

The perimeter of the kite is the sum of the length of each side. Therefore,

Perimeter = 5 + 5 + 7.616 + 7.616 = 25.2 units to the nearest tenth
