To do the multiplication, we multiply 0.63 by each of the digits & decimal places of 0.24 (and align the products that we get) then add them together.
0.63 x 4 = 2.52, therefore the first missing spot is a 2.
0.63 x 2 = 1.26, therefore the second missing spot is a 2 (the 0 is so that the decimal point can be aligned for the result.)
Answer:
B) 3.16 pounds
Step-by-step explanation:
Accuracy is how close a measured value is to the actual or true value. The balance is accurate to the nearest 1/100 pound; thus, the highest level of accuracy appropriate to the limitations of the balance.
Answer:
Putting the value of x= 2 in the first equation,
6(2)+y= 17
y= 17-12 = 5
This value is same as the value for y given in the question.
Therefore, it satisfies the equation.
Again, putting the value of x= 2 in the second equation,
3(2)+14y= 16
14y= 16-6 = 10
y= 10/14 = 5/7
It doesn't satisfies the 2nd equation
Hence, (2,5) is not the solution to this system.
Answer:
C
Step-by-step explanation:
We can solve simultaneous equations using substitution method, elimination method or graphical method. But for this purpose, we will be using the elimination method.
3x+4y=8 Equation 1
2x+y=42 Equation 2
Multiply Equation 1 by 2 and equation 2 by 3, so as to get the same coefficient for x
2(3x+4y=8)= 6x+8y=16 Equation 3
3(2x+y=42)= 6x+3y=126 Equation 4
Subtract equation 4 from 3, to eliminate x
6x-6x=0
8y-3y= 5y
16-126= -110
We now have 5y=-110
Divide both sides by 5,
y= -110/5
= -22
Substituting for y in equation 2
2x+(-22)= 42
2x= 42+22
2x=64
x= 64/2
= 32
(x, y)
(32, -22)
