Find <ABC =2x and <CBD=3x-10​

Mathematics
1 answer:
Romashka-Z-Leto [24]3 years ago
3 0

Answer:

x = 20

Step-by-step explanation:

m<ABC and m<CBA are complementary angles which means their sum is 90 degrees:

2x + 3x - 10 = 90 add like terms

5x - 10 = 90 add 10 to both sides

5x = 100 divide both sides by 5

x = 20 to find the angles replace x with 20

m<ABC = 40 and

m<CBA = 50

There are 81 red, blue and yellow
wel

Step-by-step explanation:

Here Given

Total counters = 81

red counters are 9 more than the yellow ones.

And Yellow counter = blue counter

So let the Yellow counter be x and as blue counter and yellow counter are same then blue counter will be also x

And by the question

Red counter = 9 + x

Now

9 + x + x + x = 81

9 + 3x = 81

3x = 81 - 9

3x = 72

x = 72 / 3

Therefore x = 24

Now

Red counters = 9 + 24 = 33

Blue counters = 24

Yellow counters = 24

Hope it helped :)

The piecewise function h(x) is shown on the graph.
Artemon [7]

Step-by-step explanation/Answer:

<u><em>The value for h(3) is 1.</em></u>

<u><em>Coordinate (3,1)</em></u>

The value on h(3) is located in the last part of the piecewise function, which starts at (1,3) until (4,0). To know the exact image of h(3), we can find the function that belongs to that piece of line, and then calculated the asked value.

So, to calculate the equation, we first have to find the slope with its definition, and then we'll use the point-slope formula to find the equation:

<u><em>Therefore, the coordinates is (3,1), that is, the value for h(3) is 1.</em></u>

The Ratio of red jackets to blue jackets is 3 to 4. If there were 36 blue jackets in the closet, how many red jackets would be t
oksian1 [2.3K]

Answer:

27

Step-by-step explanation:

The 4 part of the ratio refers to 36 blue jackets.

Divide 36 by 4 to find the value of one part of the ratio

36 ÷ 4 = 9 ← value of 1 part of the ratio, then

3 parts = 3 × 9 = 27 ← number of red jackets
