Answer:

1/4

Step-by-step explanation:

Distribute.

7 - 7y = -3y + 6

Get all ys on one side

7 = 4y + 6

Get constants all on one side.

1 = 4y

Divide

1/4 = y

find the probability of drawing a diamond 8 through 10 on the first draw, replacing it, and drawing a black card on the second d

Montano1993 [528]

Drawing an 8, 9 or 10 of diamonds would be 3/52 ( cards out of 52 total cards)

Drawing a black card would be 1/2 ( half the deck is black)

The probability of both happening is 3/52 x 1/2 = 3/104

–0.2(x – 20) = 44 – x

GarryVolchara [31]

$-0.2(x-20)=44-x\qquad\text{use distributive property}\\\\-0.2x+4=44-x\qquad\text{subtract 4 from both sides}\\\\-0.2x=40-x\qquad\text{add x to both sides}\\\\0.8x=40\qquad\text{divide both sides by 0.8}\\\\x=\dfrac{40}{0.8}\\\\x=\dfrac{400}{8}\\\\\boxed{x=50}$

Given: measure of angle KJ = 124°, measure of IC =38°<br><br> Find: m∠CQJ, m∠LIJ.

VLD [36.1K]

Answer:

Part 1) $m$

Part 2) $m$

Step-by-step explanation:

Part 1) Find the measure of angle CQJ

we know that

The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite.

$m$

$arc\ IK+arc\ CJ=360\°-(arc\ IC+arc\ KJ)$

substitute the values

$arc\ IK+arc\ CJ=360\°-(38\°+124\°)=198\°$

$m$

Part 2) Find the measure of angle LIJ

step 1

Find the measure of angle IJL

we know that

The inscribed angle is half that of the arc it comprises.

$m$

substitute the values

$m$

step 2

Find the measure of angle ILJ

we know that

The measurement of the external angle is the semi-difference of the arcs it encompasses.

$m$

substitute the values

$m$

step 3

Find the measure of angle LIJ

Remember that the sum of the interior angles of a triangle must be equal to 180 degrees

In the triangle LIJ

$m$

substitute the values

$m$

$m$
