Answer:
a) 21m - 0.87 = m
b) m = 0.0435 mg
21(0.0435) - 0.87 = 0.0435
0.9135 - 0.87 = 0.0435
0.0435 = 0.0435
True statement, so correct
c) 21m - 0.87 = m
20m = 0.87
m = 0.87/20
m = 0.0435 mg
The value of x is 13
<h3>How to determine the value</h3>
From the diagram shown, we have that the line segments as;
NK = NM + ML + LK
Where;
- NK = 23
- NM = x - 6
- ML = 9
- LK = 2x - 19
Substitute the values into the equation
(x - 6) + 9 + 2x - 19 = 23
collect like terms
x + 2x -6 + 9 - 19 = 23
Add like terms
3x - 16 = 23
3x = 23 + 16
3x = 39
Divide both sides by 3
x = 39/ 3
x = 13
Thus, the value of x is 13

3. 7
5. 13
6. -9

10. -27.2
11. 22 * 2 + 7 * 0 - 5 * 1 = 39
Answer:
y = -27
Step-by-step explanation:
- Multiply the entire equation by 6

2*(y + 1) - (3y - 1 ) = 30
- Multiply (y +1) by 2 and (3y - 1) by (-1)
2y + 2 - 3y + 1 = 30
- Isolate y term by taking the constant term to RHS
2y - 3y = 30 - 2 - 1
-y = 27
y = -27
Answer:

Step-by-step explanation:
we know that
The lateral area of the figure is given by

where
P is the perimeter of the base (larger faces)
h is the height
Find the perimeter of the base P

we have

substitute in the formula of lateral area
