What is the variable for -7.8 = 4.4 + 2r

Mathematics
1 answer:
balandron [24]3 years ago
6 0

Answer:

r = -6.1

Step-by-step explanation:

-7.8 = 4.4 + 2r

To get r, you need to isolate the variable

Subtract the 4.4 from both sides

-7.8 - 4.4 = 4.4 + 2r - 4.4

4.4 cancels out on the right

-12.2 = 2r

Divide both sides by 2

-12.2/2 = 2r/2

-6.1 = r

5 + 14 x y = 9 x y - 5
Anon25 [30]

Answer:

xy = -2

Step-by-step explanation:

To solve:

5 + 14xy = 9xy - 5

=> First subtract 9xy from each side of "="

5 + 5xy = -5

=> Now, subtract 5 from each side:

5xy = -10

=> Finally divide 5 on each side:

xy = -10/5

xy = -2

Hope this helps!

Find the value of X round your number to the nearest tenths<br><br><br> Explain it please
Anarel [89]

In this case, we must use trigonometry to find the value of x:

        tan(\alpha )=\frac{side-opposite-angle}{side-beside-angle} \\tan(70) = \frac{x}{3} \\3*tan(70) = x\\x = 3*tan(70)\\x = 8.24

Thus the value of x rounded to the nearest tenth is <u>8.2</u>

<u></u>

Hope that helps!

▹ Answer

<em>y = 15, -15</em>

▹ Step-by-Step Explanation

This is considered a 'square root' since we have to find y^2.

15 * 15 = 225

-15 * -15 = 225

Both of these values work for y, so the answer is 15, -15.

Hope this helps!
