Can u be specific pls , so can u send the picture of the task
Hey there! :)
70 million = 70,000,000
7 million = 7,000,000
All you have to do is divide
70,000,000 ÷ 7,000,000 = 10
Answer ⇒ 10 times greater

Given:
Q = 0.0764 kJ = 764 J, heat input
W = -830 J, useful work done
From the 1st Law of Thermodynamics, the change in internal energy is
δE = Q - W
= 764 - (-830)
= 1594 J = 1.594 kJ
Answer: 1.59 kJ (two sig. fig.)
<u>Answer:</u>
<em>Equation is 4x-6(6x-1) = -11
</em>
<u>Step-by-step explanation:</u>
<em>The set of equations given are
</em>
<em>6x-y=1
</em>
<em>4x-3y=-11
</em>
A pair of linear equations in <em>two variables x and y is given</em> in the set of equations. If there are two variables we require two equations to find the <em>value of variables</em>. Substitution is one among the methods used to solve pair of linear equations in two variables.
Here we have to <em>determine the value of y</em> from the first equation and then substitute it in the second equation.
<em>6x-y=1
</em>
<em>y=6x-1
</em>
<em>Substituting this value in second equation 4x-6y=-11 </em>
<em>we get </em>
<em>4x-6(6x-1) = -11
</em>
