Given:

Two parallel lines are cut by a transversal and form a pair of alternate interior angles.

One angle measures (6x + 5)° and the other measure (7x - 4)°

We need to determine the measure of each angle.

Value of x:

Since, the two angles are alternate interior angles, then the two angles are congruent.

Thus, we have;

$6x+5=7x-4$

$-x+5=-4$

$-x=-9$

$x=9$

Thus, the value of x is 9.

Measure of each angle:

The measure of each angle can be determined by substituting $x=9$ in the measures of each angle.

Thus, we have;

$(6x + 5)^{\circ}=(6(9) + 5)^{\circ}=59^{\circ}$

$(7x - 4)^{\circ}=(7(9) - 4)^{\circ}=59^{\circ}$

Thus, the measure of each angle is 59°

There are many ways to produce crooked dice. To load a die so that 6 comes up too often and 1 , which is opposite 6 , comes up t

Andreas93 [3]

Answer:

1 2 3 4 5 6

2 ÷ 15 1 ÷ 6 1 ÷ 6 1 ÷ 6 1 ÷ 6 1 ÷ 5

Step-by-step explanation:

As it is mentioned in the question that the probability of faces like 2,3,4,5 are not affected so in this case

P(2) = P(3) = P(4) = P(5) = 1 ÷ 6

And, P(6) = 0.2

As we know that

P(1) + P(2) +P(3) +P(4) +P(5) +P(6) = 1

This results P(1) = 2 ÷ 15

So,

1 2 3 4 5 6

2 ÷ 15 1 ÷ 6 1 ÷ 6 1 ÷ 6 1 ÷ 6 1 ÷ 5

Hence, the correct option is 2nd

Use a separate sheet of paper to solve the system of inequalities by graphing. Use the graph to decide if the point (1, –1) is i

Lena [83]

Answer:

The answer is no though, the point (1,-1) is below both.

Step-by-step explanation:

So the two inequalities are y≤-3x+3 and 3x+8y≥3

With inequalities you have to know a few things. First, when you graph you may have to use non solid lines. for instance, if you had x<5, 5 would not be part of the answer because it is only answers less than 5. so you represent this by making a dashed line that says "you cannot include values on this line". Second, with algebra, if you multiply both sides by a negative it flips the inequality. for instance -y > 54 you would multiply (or divide) by -1 and it would change to y < -54. Third, when graphing an inequality, treat it like an equation and graph the line as if it were said equation(with solid or dashed lines as needed) then, if it is y > f(x) you shade in the section above the line and y < f(x) shades in below. The shaded part is your answer basically. Now lets get into yours.

y≤-3x+3

It is already in the form y = f(x) so grapht he line 3x + 3 with a solid line since it is y is less than or equal to, then shade below that line.

3x+8y≥3

First get it so y is by itself

3x+8y≥3

8y≥3 - 3x

y ≥ 3/8 - 3/8 x

Now grapht his line with a solid line and shade the area above it.

Now, the shaded area below between y ≥ 3/8 - 3/8 x and y≤-3x+3 and the lines are your answer, so you need to check if the point (1, -1) is in this shared shaded area or on one of the lines.

The answer is no though, the point (1,-1) is below both.

Geoff likes to go bowling. He has $225.00 and would like to buy a bowling ball and use the rest of the money to pay for games of

You have to minus 225 from 55 then divide it by 3.50 which would be 48.5 games
