Hey there!☺

$Answer:\boxed{y>x+5}$

$Explanation:$

Solve for y | $-3x+3y>15$

In step 1, we will add 3x to both sides:

$-3x+3y+3x>15+3x\\3y>3x+15$

In our second/last step, we will divide both sides by 3:

$\frac{3y}{3}>\frac{3x+15}{3}\\ y>x+5$

y>x+5 is your answer.

Hope this helps!☺

Maricella solves for x in the equation 4x-2(3x-4)+4=-x+3(x+1)+1. She begins by adding –4 + 4 on the left side of the equation an

Elodia [21]

Maricella’s strategy is incorrect as the values added on the left and right side of the equation changes the original equation $4x-2(3x-4)+4=-x+3(x+1)+1$ to $4x-2(3x-4)+4=-x+3(x+1)+3$ .

Further explanation:

Maricella begin by adding $-4+4$ on the left side of the equation and $1+1$ on the right side of the equation $4x-2(3x-4)+4=-x+3(x+1)+1$ .

The value added on the left is equal to zero so it does not change the equation but the value added on the right is 2, a non-zero digit so it changes the equation as shown below.

$4x-2(3x-4)+4-4+4=-x+3(x+1)+1+1+1\\4x-2(3x-4)+4+0=-x+3(x+1)+1+2\\4x-2(3x-4)+4=-x+3(x+1)+3$

Therefore, the strategy used by Maricella will change the equation and so the solution of the equation will be incorrect.

One way of solving such a linear equation is by adding or subtracting the required value on each side of the equation. and then simplifying the further equation.

Similarly, the other way to solve any linear equation is by separating the variable terms on one side of the equation and constant terms on the other side of the equation.

After this simplify the linear equation to obtain the solution of the equation for $x$ .

Whereas Maricella’s strategy fails to solve the equation $4x-2(3x-4)+4=-x+3(x+1)+1$ since the values added and subtracted in the equation changes the original equation completely.

Two students from a group of eight boys and 12 girls are sent to represent the school in a parade.

Deffense [45]

<u>Answer</u>

c. 62/95

<u>Explanation</u>

Probability is the chance of an event happening.

Probability = (favorable outcome)/(total outcome)

P(girl) = 12/20 × 11/19

= (12×11)/(20×19)

= 132/380

= 33/95

P( not a girl) = 1 - 33/95

= 62/95

What is the measure of BC⏜ ? Enter your answer in the box. ° Circle with inscribed angle B D C. Angle B D C is 65 degrees.

Zigmanuir [339]

Answer:

Minor arc BC - 130° (arc at which inscribed angle is subtended)

The major arc BC - 230°

Step-by-step explanation:

Angle BDC is inscribed angle subtended on the arc BC.

The measure of the angle BDC is 65°.

The Central Angle Theorem states that the central angle from two chosen points B and C on the circle is always twice the inscribed angle from those two points.

By the central angle theorem, the measure of central angle BOC (O is the center of the circle) has the measure of

$2\cdot 65^{\circ}=130^{\circ}$
