The answer is going to be y=-1.75 hope this helps!!
The number of milligrams of aluminum is 400 times the number of milligrams of gold in the body.
<u><em>Explanation</em></u>
Lets assume, the number of milligrams of aluminum is
times the number of milligrams of gold in the body.
The body of a 154 pound person contains approximately 4 × 10⁻¹ milligrams of gold and 16 × 10¹ milligrams of aluminum.
So the equation will be...

So, the number of milligrams of aluminum is 400 times the number of milligrams of gold in the body.
Answer:
<h3>Q1</h3>
- This is acute angle since 75° < 90°
<h3>Q2</h3>
- This is an isosceles triangle
<h3>Q3</h3>
<u>Exterior angle is the sum of non-adjacent interior angles:</u>
- 4x + 7 + 6x - 9 = 118
- 10x - 2 = 118
- 10x = 120
- x = 12
m∠L = 4*12 + 7 = 48 + 7 = 55°
<h3>Q4</h3>
<u>The triangles are congruent and corresponding sides are equal:</u>
- 3x - 5 = 2x + 1
- 3x - 2x = 1 + 5
- x = 6
<u>Side lengths are:</u>
In a 30°-60°-90° triangle, the ratio of the legs is

So if the shorter leg is

, then the longer leg is
