What is the value of x in the equation 4x+8y=40 when y=0.8
GREYUIT [131]
Substitute in 0.8 for y.

4x+8y=40 \\ \\ 4x + 8(0.8) = 40 \\ \\ 4x + 6.5 = 40 \\ \\ 4x = 40 - 6.4 \\ \\ 4x = 33.6 \\ \\ x = 8.4 \\ \\

The final result is: x = 8.4.

you have a bag with 20 marbles 2 yellow 5 green 12 red and 1 blue which of the following statements are true? Select all that ap
NNADVOKAT [17]
  1. An event has probability 1 if you're certain that it will happen. You are sure to pick a marble that's either yellow, green, red, or blue. So, this probability is 1.
  2. There are more yellow marbles than blue marbles, so it's actually more likely that you'll pick a yellow one, rather than the blue one.
  3. The probability of picking a green marble is given by the number of green marbles divided by the total number of marbles. Compute this ratio and see what you get.
  4. Similarly, the probability of picking a black marble is given by the number of black marbles divided by the total number of marbles. There are no black marbles, so...

Please Help!<br> The following is an isosceles trapezoid, find m &lt; J
ra1l [238]

Answer:

<em>The measure of angle J is 44°</em>

Step-by-step explanation:

<u>Isosceles Trapezoid</u>

The isosceles trapezoid has its non-parallel sides of the same length, thus the angles they form with their respective parallel sides are congruent.

It means: Angle J is congruent with angle K and angle M is congruent with angle L

The sum of angles in a trapezoid is 180*(4-2)=360°

Thus:

m\angle J+m\angle K+m \angle M+m\angle L = 360^\circ

7x+2+7x+2+25x-14+25x-14=360

Joining like terms:

64x-24=360

Adding 24:

64x=384

Dividing by 64:

x=6°

Thus:

m\angle J = 7*6+2=44^\circ

m\angle M = 25*6-14=136^\circ

The measure of angle J is 44°
