Answer:

-9

Step-by-step explanation:

-9  * -9 = 81

-9 + -9 = -18

Answer: -9

Answer:

12

Step-by-step explanation:

Since this is a right angle triangle, and we have two lengths already found, we can use pythagoras to find x.

We know that

a²+b²=c²

Where a, and b are the smaller lengths (the adjacent and opposite), and C is always the longest one (the hypotenuse).

We want to find x, which in this case is c. So,

to solve for c, we get

c=[tex]\sqrt{a^2+b^2 }[/tex]

So, after plugging in the values, we get

[tex]c=\sqrt{10.6^2+6.1^2}[/tex]

[tex]c=12.23\\\\=12 (rounded)[/tex]

x² = (10,6)² + (6,1)²

x² = 112,36 + 37,21

x² = 149,57

x = 12,22mi✔

Answer:

When y = 20 ,x is −5

Step-by-step explanation:

Answer:

420 seconds is equal to 7 min

So 7 to 10 or 7 : 10

pls brainliest

These are the steps that you should follow in order to make the necessary calculations to convert 420 Seconds to Minutes. In order to convert from [s] to [min], we have to devide the amount of Seconds by 60.

Then the second step, is to substitute the amount of Seconds with the value of 420 and calculate the division. After successfuly calculating it the result should for 420 Seconds to Minutes should be 7

So 7 to 10 or 7 : 10

Hope this helped!

Have a great day

Option B is correct

The ratio of apples to oranges, written as a fraction If Keenan makes a basket with 6 apples, is 5 / 4.

Only verbal descriptions of a portion of the whole were used to write fractions in ancient Rome. The numerator and denominator of fractions are first written in India with one number above the other but without a line. The line used to divide the numerator and the denominator were only added by Arabs.

Given:

For every 4 oranges, there are 5 apples,

Keenan makes a basket with 6 apples,

Calculate the number of oranges as shown below,

The number of oranges = 4 / 5 × 6 = 24 / 5

Calculate the fraction of apples to oranges as shown below,

Ratio = The total number of apples / The number of oranges

Ratio = 6 / 24 / 5

Ratio = 30 / 24

Ratio = 5 / 4

Thus, the ratio is 5 / 4.

Answer:

no solution

Step-by-step explanation:

4(9x + 4) = 36x - 7 ← distribute parenthesis on left by 4

36x + 16 = 36x - 7  ( subtract 16 from both sides )

36x = 36x - 23 ( subtract 36x from both sides )

0 = - 23 ← False statement

This indicates the equation has no solution
