x= first odd integer 
x+2 = second odd integer
x+4= third intenger

The sum of the trhree integer is 195, so:

x + (x+2) + (x+4) = 195
3x = 195 - 4 - 2
3x=189
x= 63

Tan39= x/68<br> Plz help. Will give brainliet
lesya [120]

Answer:

\huge\boxed{x \approx 55}

Step-by-step explanation:

We need to note that this is an equation, in which we can solve for x.

tan(39) = \frac{x}{68}

We can use a calculator to find the tangent of 39 - we type 39 into the calculator then press the "TAN" button to find it's tangent. We find that to be around 0.81.

We now have the formula simplified down to 0.81 = \frac{x}{68}. To solve for x, we want to isolate it on one side, so we can multiply both sides by 68 to get rid of the fraction.

We know have 0.81 \cdot 68 = x

0.81 \cdot 68 = 55.08 \approx 55, so x is approximately 55.

Hope this helped!

James earned $816 each year. He earned x dollars less per month than Matt, who earned $80 per month. Equation: 12(80 – x) = 816
Nataly_w [17]

Answer:

see below

Step-by-step explanation:

12(80 – x) = 816

Divide each side by 12

80-x = 816 /12

80-x = 68

Subtract 80 from each side

80-x-80 = 68-80

-x = -12

Multiply each side by -1

x = 12

James earned 80-12 = 68

Yuri [45]
The equation is
y = $10,000+ $225x


<em>$225 (6) + $10,000 = y</em>

<em>$1,350 + $10,000 = y</em>

<em>$11,350 = y</em>

He will have saved $11,350 dollars in six months.
