Solve the equation <br> 14(3x-1)=2x-23

irina1246 [14]

Answer:

$x=\frac{-9}{40} \\$

Step-by-step explanation:

Given Equation:

$14(3x-1)=2x-23$

Solving the bracket on L.H.S

$(14)(3x)-1(14)=2x-23$

$42x-14=2x-23$

Taking the terms of 'x' to one side and the constants to other side

$42x-2x=-23+14\\\\40x=-9\\\\x=\frac{-9}{40} \\$

The value of 'x' after solving the equation is:

$x=\frac{-9}{40} \\$

Find the value of x.

koban [17]

Answer:

x = 110°

Step-by-step explanation:

The Outside Angle Theorem states that the measure of the angle formed by two secants or a secant and tangent from a point outside of a circle is half the difference between the two arcs.

This means that ½ (210 – x) = 50.

½ ( 210 – x ) × 2 = 50 × 2

210 – x = 100.

210 – x + x = 100 + x.

210 = 100 + x.

100 + x = 210.

100 + x – 100 = 210 – 100.

x = 110.

This value must be true because:

½ ( 210 – 110 ) = 50.

½ ( 100 ) = 50.

50 = 50.

Evaluate this expression for x=-5 and y=-5

Talja [164]

Answer:

$x - 2y=5$

Step-by-step explanation:

Given

$x = -5; y=-5$

$x - 2y$ --- missing from question

Required

Evaluate

We have:

$x - 2y$

Substitute for x and y

$x - 2y=-5 - 2*-5$

$x - 2y=-5 +10$

$x - 2y=5$
