If –8x + 2y = -4 is a true equation, what would be the value of 40x – 10y?

Answers

Answer 1
If u need to find the values for X & Y I believe this is the right answer

X = 1 —— Y = 2
-8x + 2y = -4
-8(1)+ 2(2) = -4

40x - 10y
40(1) - 10(2)
40 - 20 = 20

Answers

Answer:

If this is a parallelogram:

∠y = 112°

corners opposite the 112° corners = 68°      [(360° - 112° - 112°)/2 = 68°]

∠z = 68° - 40° = 28°

∠x = ∠z = 28°

Answer:

x = 28°, y = 112°, z = 28°

Step-by-step explanation:

suppose it's a parallelogram,

in a parallelogram, opposite angles are congruent: y = 112°

40 + 112 + x = 180

=> x = 28°

If 2 lines are cut by a transversal, then the alternate interior angles are congruent: x = z => 28° = z

A photographer shines a camera light at a particular painting forming an angle of 40° with the camera platform. If the light is 58 feet from the wall where the painting hangs, how high above the platform is the painting?

Answers

Answer:

Let y be the height above the camera platform of the painting.

tan (40degrees) = y/58

y = 58[tan(40)] = 58(0.8391) = 48.67 feet.

y = 48.67 feet

which is the solution to 4/5(n-3)=n-2

Answers

Answer:

-2 = n

Step-by-step explanation:

Multiplying both sides by (5/4) quickly isolates (n - 3):

(5/4)(4/5)(n - 3) = (5/4)(n - 2), or

n - 3 = (5/4)(n - 2)

Let's eliminate fractions by multiplying both sides by 4:

4n - 12 = 5n - 10

Combining like terms, we get -2 = n

Harrison ,Tad and dale ride their bikes to school Harrison rides 3/4 mile,Tad rides 3/8 and dale rides 3/6 mile. Compare and order and distances the boys ride from least the greatest

Answers

Answer:

3/8 , 3/6. 3/4

Tad drove the least miles because the miles ridden is less than both 3/6 and 3/4 miles

Dale rode the second greatest mile because the miles ridden is greater than 3/8 but less than 3/4

Harrison rode the greatest mile because the miles ridden is greater than both 3/6 and 3/8

Step-by-step explanation:

to order the miles ridden , convert the fraction to decimals. to do this, divide the numerator by the denominator

3/4 = 0.75

3/6 = 0.5 miles

3/8 = 0.374

Find m < ABC.

Answers

Answer:

m<ABC=51°

Step-by-step explanation:

The inscribed angle is half the measure of the intercepted arc. This means that angle ABC=1/2 arc AC

Using this, let's make an equation

5x+11=(1/2)(16x-26)

5x+11=8x-13

11=3x-13

24=3x

x=8

Now go back to angle ABC and substitute for x

5(8)+11=51

m<ABC=51°

Answer:

m<ABC = 51

Step-by-step explanation:

m<ABC = 1/2 arc AC

(5x + 11) = 1/2(16x-26)

x=8

Plug it in

5(8) + 11 = 51

Imagine two lines intersect. How can the properties of linear pairs and vertical angles help to determine the angle measures created by the intersecting lines? Explain

Answers

when 2 lines intersect ,4 angles are formed.in that vertically opposite angles will be equal. adjacent angles will be found using linear pair{sum of linear pair of angles will be 180degree}

Answer:

If you know the measure of one angle in a linear pair, you can find the measure of the other because the sum of the measure of the two angles is 180 degrees. If you know the measure of one angle in a pair of vertical angles, you can find the measure of the other because they are congruent.

Answers

Answer:

9 sides

Step-by-step explanation:

Each interior angle of a regular polygon is 100 degrees larger than the exterior angle determine the number of sides of the polygon

Interior angle + exterior angle =

180°

Let x be the exterior angle.

Exterior angle = 180-x = 100 + x

= 180 - 100 = x + x

80 = 2x

x = 80/2

x = 40

Number of sides of the polygon =

= 360°/Exterior angle

Exterior angle = 40°

= 360/40 = 9 sides
