Given:
m∠D = 5x - 10
m(ar EC) = 60°
m(ar RB) = 13x + 7
To find:
The value of x.
Solution:
<em>If two secants intersect outside a circle, then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.</em>



Multiply by 2 on both sides.


Add 53 on both sides, we get

Subtract 10x on both sides, we get

Divide by 3 on both sides, we get

The value of x is 11.
Answer:
Option A will be correct option which represent the equation y = -8x + 50 Step-by-step explanation:
Answer:
$2.73 per gallon.
Step-by-step explanation:
Divide 18 from 49.10 to find the unit rate.
49.10/ 18 = 2.7277... <em>The seven is continued.</em>
2.7277... is the unit rate.
The cost per gallon is $2.73
Equation 1: 3x + 2y + 4z = 12
Equation 2: x + y + 2z = 6
Substituting x = 0, y = 4 and z = 1 into equation 1 and equation 2 and if the answer equals to 12 and 6 then the two lines intersect at the given point
Equation 1 ⇒ 3(0) + 2(4) + 4(1) = 0 + 8 + 4 =12
Equation 2 ⇒ 0 + 4 + 2(1) = 4 + 2 = 6
We have the answer of 12 and 6, hence the two lines intersect at the given point
-------------------------------------------------------------------------------------------------------------
Equation 1: -2x - 4y + z = 8
Equation 2: 4x + 2y = -5
Given point: x = -2, y = 0, and z = 3
Equation 1 ⇒ -2(-2) - 4(0) + 3 = 4 - 0 +3 = 7
Equation 2 ⇒ 4(-2) + 2(0) = -8 + 0 = -8
The answers are not 8 and -5 hence the lines don't intersect at given point
4.55 because u just divide them together do all the work and thats what u get
