<em><u>Answer:</u></em>
x = 8
<em><u>Step-by-step explanation:</u></em>
Okay, so with the info here, we know that angle RXS is 4x + 1, angle SXT is x + 9, and angle RXT is 50.
Angle RXT is angle RXS + angle SXT because it's on the diagram. So from
RXT = RXS + SXT, we can creat the equation:
50 = (4x + 1) + (x + 9) [Because we plug in the values]
So from here, we have to solve the equation:
50 = (4x + 1) + (x + 9)
First, we want to simplify everything so:
50 = 5x + 10
Then we want to isolate the variable so:
50 - 10 = 5x + 10 - 10
40 = 5x
40/5 = 5x/5
8 = x
<u>x = 8</u>
3/4 / 2/1
Keep, Change, Flip
3/4 * 1/2 = 3/8
5/4 / 2/1
Keep, Change, Flip
5/4 * 1/2 = 5/8
Answer: 3/8 and 5/8
<h3>Radius of circle is 2.5 feet</h3><h3>Diameter of circle is 5 feet</h3>
<em><u>Solution:</u></em>
Given that,
Circumference of circle = 15.7 feet
<em><u>The formula for the circumference of a circle is:</u></em>
Where, "r" is the radius of circle
Given that,
C = 15.7 feet
Therefore,
Thus radius of circle is 2.5 feet
Also,
Diameter = 2( radius )
Diameter = 2 (2.5) = 5
Thus diameter of circle is 5 feet
3(5z - 7) + 2(9z - 11) = 4(8z - 7) - 111
15z - 21 + 18z - 22 = 32z - 28 - 111
33z - 43 = 32z - 139
33z - 32z = -139 + 43
z = - 96
Answer: x= -8.5
Step-by-step explanation:
-4x+8=42
-8 -8
-4x=42-8
-4x=34
x=-34/4
x=-17/2
x= -8.5
