Find the value of x (6x + 7)° (8x - 17)°

<h3>Answer:  x = 12</h3>

Explanation:

The two angles shown are vertical angles. This occurs whenever you have an X shape like this, and whenever the angles are opposite one another. Vertical angles are always congruent.

6x+7 = 8x-17

6x-8x = -17-7

-2x = -24

x = -24/(-2)

x = 12

Answer:

160 sq cm

Step-by-step explanation:

Since the two trapezoids are similar, you can use a ratio to find the area.

If we use x to represent the area of ABCD, then the ratio will look something like:

5/20 = 40/x

which then we can solve x to be 160 sq cm.

Can someone answer this
bezimeni [28]

Answer:

Step-by-step explanation:

x         6         a

8       48        c  

-4        b       20

Let the unknown numbers of the multiplication grid are a, b and c.

1). 6 × 8 = 48

2). (-4)×6 = b

    b = -24

3). (-4) × a = 20

   a = -5

4). 8 × a = c

    8 × (-5) = c

    c = -40

Therefore, missing in the given multiplication grid are,

x         6        -5

8       48       -40  

-4      -24       20

Neil has 3 partially full cans of white paint.They contain 1/3 gallon,1/5 gallon,and 1/2 gallon of paint.About how much paint do
Wittaler [7]

Answer:

  less than 1 1/2 gallons

Step-by-step explanation:

1/3 + 1/6 = 1/2, so the sum of the three cans is more than 1 by the difference between 1/5 and 1/6. That difference is 1/30 gallon. The sum is 1 1/30 gallons, which is less than 1 1/2 gallons.

__

A suitable common denominator is 2·3·5 = 30. Then the sum of the fractions is ...

  1/3 + 1/5 + 1/2

  = 10/30 + 6/30 + 15/30

  = 31/30 = 1 1/30 . . . . . less than 1 1/2

In decimal, 1/3 ≈ 0.333, 1/5 = 0.200, 1/2 = 0.500, so the sum is ...

  0.333 +0.200 +0.500 = 1.033

which is less than 1.5.
