it would be equation c, since you are you going upstream and the current would be going down stream

20 POINTS PLEASE ANSWER<br> Use the relationships between the angles to find the value of x
WARRIOR [948]

Answer:

x = 25 degrees

Step-by-step explanation:

So we know that the 4x, 2x + 10°, and x - 5° and the measures of the three interior angles of the triangle. The sum of the interior angles of a triangle is 180°.

Using this, we can conclude that the sum of 4x, 2x + 10°, and x - 5° is equal to 180°.

We can write this information as the equation:

4x + (2x + 10) + (x - 5) = 180

We can use this equation to find the value of x. To find the value of x by using the equation, we need to solve for x (put the equation into the form x = _).

Solve for x:

4x + (2x + 10) + (x - 5) = 180

4x + 2x + 10 + x - 5 = 180

Combine like terms.

7x + 5 = 180

Subtract 5 from both sides to get rid of the +5 on the left side.

7x = 180 - 5

Simplify.

7x = 175

Divide both sides by 7 to get rid of the coefficient of 7 on the left side.

x = 175 ÷ 7

Simplify.

x = 25.

x would be equal to 25°.

x = 25 degrees

I hope you find this helpful. :)

Given that a<span>n artist uses 8 orange beads, 3 red beads, 4 green beads and 1 string for making a special tricolored bracelet.

Given that there are </span><span>15 orange beads, 86 red beads, 92 green beads, and 17 pieces of string</span>, the number of special tricolored bracelets that can be made is 1.

This is because, since 8 orange beads is needed for the special tricolored bracelets and there are only 15 orange beads the available, there will only be 7 orange beads left for the second tricolored bracelet.
