1. Solve for x.<br> 55°<br> (3r + 23)<br> 75°
Mnenie [13.5K]

Answer:

The value of x is 9.

Step-by-step explanation:

55°

(3 x + 23)

75°

The sum of all the angles of triangle is 180°.

55 + 3 x + 23 + 75 = 180

3 x = 27

x = 9

So, the value of x is 9.

Please help I will give you Brainlest and 10 point's ​
Luba_88 [7]

a) To find the volume of a cube, you cube the side length.

So, that will be V = 9/2³ = 729/8 in³.

b) To find the volume of a rectangular prism, you multiply the length by the width by the height.

So, that is V = 18 * 9 * 9/2 = 729 in³.

c) To find how many times the smaller box can go into the larger one, you divide the larger one's volume over the smaller one's.

That is <em>729/(729/8) = 729*8/729 = </em><em>8 boxes</em><em>.</em>

In the diagram below, line d is parallel to line c.
My name is Ann [436]

Answer:

85° = ∠x {corresponding angles}

∠x = ∠1 {vertically opp. angles}

And, ∠2 + 103° = 180° ( co-interior angles)

∠2 = 180° - 103°

∠2 = 77°

Now, m∠1 + m∠2 = 85° + 77°

= 162°

Hemce, option A. is the right answer.

A student has $350.00 in her account and withdrew 3/5 of it . how much money , in dollars, remains in the account
Burka [1]

a whole, fraction wise, is always 1, so in this case we're looking at a whole of 5/5 = 1, and she withdrew 3/5, so what remained is 2/5

\cfrac{5}{5}\qquad \qquad \cfrac{5}{5}-\cfrac{3}{5}\implies \cfrac{5-3}{5}\implies \cfrac{2}{5}~\hfill 350\left( \cfrac{2}{5} \right)\implies \boxed{140}
