What is the value of x?
Mariulka [41]

Answer:  x = 7

`Step-by-step explanation:

Because the figure shows two triangles that are similar. we can write and solve an equation of ratios:

 9 cm       72 cm

----------- = -----------

3x - 20      56 cm

Cross-multiplying, we get (3x - 20)(72 cm) = (9 cm)(56 cm) = 504 cm²

Dividing both sides by 72 cm, we get:

3x - 20 = (504 cm²) / (72 cm) = 7

Then 3x - 20 = 7, and 3x = 27.  Then x must be 9.

What is the solution to the linear equation? 2/5 + p = 4/5 + 3/5p ​
masha68 [24]

Answer:

p=1

Step-by-step explanation:

2/5 + p = 4/5 + 3/5p

Multiply each side by 5 to clear the fractions

5(2/5 + p) = 5(4/5 + 3/5p)

2 +5p = 4 + 3p

Subtract 3p from each side

2+5p-3p = 4+3p-3p

2+2p = 4

Subtract 2 from each side

2+2p -2 = 4-2

2p =2

Divide by 2

2p/2 = 2/2

p=1

What is the product of 1 and 1 3rd and 7/10
Dmitrij [34]
The correct answer is 14/15. To answer this problem, it would help to change the mixed number into an improper fraction.

1 1/3
4/3   Multiply 3 by 1, and then add 1 and put 4 over 3.

4/3 x 7/10   Now, multiply both numbers by each other. Since we're multiplying, we don't need to find a least common denominator.
28/30   4 x 7 = 28; 3 x 10 = 30
14/15   Since 28 and 30 are divisible by 2, we need to simplify the answer.

The correct answer is 14/15.

Hope this helps!
