Answer:
3a - b = 1
Step-by-step explanation:
a = (2-3)
b = (1-5)
Substitute the values of a and b to the 3a-b.
3(2-3) - (1-5)
6-9 - (-4)
6 - 9 + 4
-3 + 4
= 1
Therefore, 1 is the answer.
Answer:
A) 85x=5865
x=69 Width
B)2(57)+2x=286
114+2x=286
2x=172
x=86

Answer:
The answer to your question is 75 cm
Step-by-step explanation:
Data
Student calculator Demonstration calculator
width = 15 mm width = 4.5 cm
height = 250 mm height = ?
Process
1.- Convert the width of the demonstration calculator to mm
10 mm ---------------- 1 cm
x ---------------- 4.5 cm
x = (4.5 x 10) / 1
x = 45 mm
2.- Use proportions to find the height of the demonstration calculator
250 / 15 = x / 45
- Solve for x
x = (250 x 45) / 15
-Simplification
x = 11250 / 15
-Result
x = 750 mm
3.- Conclusion
The height of the demonstration calculator is 750 mm or 75 cm
Answer:
22.5^3
Step-by-step explanation:
V=length*width*height=2*2.5*4.5=22.5 m^3
Firstly,we need to understand the properties of a parallelogram:
-Opposite sides are parallel by .
-Opposite sides are congruent.
-Opposite angles are congruent.
-The diagonals bisect each other.
Therefore in this case:
XW must be congruent to YZ.
WZ must be congruent to XY.
Hope it helps!
