Answer:
0.35 is one thousandth of 350
Step-by-step explanation:
Let
x ----> the number
we know that
The number multiplied by one thousandth must be equal to 0.35
so
The linear equation that represent this situation is
solve for x
Multiply both sides by 1,000
therefore
0.35 is one thousandth of 350
Answer:
30
Step-by-step explanation:
We require to calculate the volume of 1 brick
V = lbh ( l is length, b is breadth and h is height ), that is
V = 14 × 8 × 5 = 560 cm³
Now divide the volume of concrete available by the volume of 1 brick.
number of bricks made = = 30
The equation y= 2 has one real root and that is x=-1.
What is real roots of the equation?
We are aware that when we resolve a linear or quadratic equation, we always arrive at the value variable of the equation, or, to put it another way, we always locate the equation's solution. This "solution" is what we refer to as the real roots. For instance, when the equation -7x+12=0 is solved, the actual roots are 3 and 4.
Here given,
=> y = 2
Take y=0 then,
=> 2=0
=> =0
=>(x+1)=0
=> x=-1
Hence the given equation has one real root and that is x=-1.
