Answer:
Correct answer is: 7. y = 28° and x = 29° 8. y = 7 and x = 5
Step-by-step explanation:
7.
In the parallelogram, adjacent angles are supplementary and the opposite angles are the same.
According to this:
(3 y - 20) + (4 y + 4) = 180 => 7 y - 16 = 180 => 7 y = 180 + 16 => 7 y = 196
y = 196/7 = 28° => y = 28°
4 x + (2 x + 6) = 180 => 6 x + 6 = 180 => 6 x = 180 - 6 => 6 x = 174
x = 174/6 = 29° => x = 29°
8.
At the parallelogram, the diagonal is split into two equal parts.
According to this:
3 y - 3 = 2 y + 4 => 3 y - 2 y = 4 + 3 => y = 7
x - 1 = 2 x - 6 => 2 x - x = 6 - 1 => x = 5
God with you!!!
<em>x = - 2</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>5x - 6 = - 16</em>
<em>5x = - 16 + 6</em>
<em>5x = - ( 16 - 6)</em>
<em>5x = - 10</em>
<em>x = - 10 : 2</em>
<em>x = - 2</em>

Answer:
33.6 grams
Step-by-step explanation:
Rate 1;
8 hours = 1.6 g
24 hours = 24 × 1.6/8 = 4.8 hours
Rate 2;
4 hours = 1.6 g
72 hours = 72 × 1.6/4 = 28.8 g
Total grams of Drug A that the patient receive
altogether = 28.8 + 4.8 = 33.6 g
Answer:
7x
Step-by-step explanation:
4x ( linear function) + 3x ( linear function) = 7x
Answer:
? = 30
Step-by-step explanation:
If the triangles are similar, then the only way I see this working is the sides measuring 63 and 54 are corresponding. The sides measuring 56 and 48 are corresponding. That leaves the sides measuring 35 and ? corresponding.
Set up a proportion.
63/54 = 35/?
63? = 54 * 35
63? = 1890
? = 30
