5 times 1/10 is 5/10 or 1/2 of a kg. This equals 0.5 kg. You can do 3 experiments (use up until 4.5 kg)
A parallelogram has two pairs of opposite equal angles.
ABCD so
A = C and B = D
A = 2x + 35
C = 3x - 5
2x + 35 = 3x - 5
35 + 5 = 3x - 2x
40 = x
A = (2 x 40) + 35 = 115
A = C = 115
Sum of angles of a quadrilateral = 360
Angles B and D are equal
So
B = (360 - (115 + 115))/ 2
= 130/2
= 65
B = D = 65
Answer: -1
Step-by-step explanation:
− 0.25(−8+12) = -0.25 x 4 =-1
Answer:
The number is 6
Step-by-step explanation:
We let the number be x. If we subtract -2 from x we obtain the following result;
x - (-2)
This can be simplified to yield the following result;
x - (-2) = x + 2
we use the rule that negative multiplied by negative yields a positive sign.
We are further informed that the result of the above operation is 8, therefore;
x + 2 = 8
Solving for x yields;
x = 8 -2
x = 6
