Answer:
-6
Step-by-step explanation:
3*x/3=-2*3
^-- times both sides by the denominator (3)
the threes on the left side of the equal sign will cancel themselves out. you are thn left with
x=-2*3
-2*3=-6
so
x=-6
Answer:
0.4032
Step-by-step explanation:
1. We assume, that the number <em>72 is 100%</em> - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If <em>72 is 100%</em>, so we can write it down as <em>72=100%</em>.
4. We know, that x is <em>0.56%</em> of the output value, so we can write it down as <em>x=0.56%</em>.
5. Now we have two simple equations:
1) <em>72=100%</em>
2) <em>x=0.56%</em>
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
<em>72/x=100%/0.56%</em>
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
Answer:
Step-by-step explanation:
There are 3 boxes. The formula for volume is lxhxw, (length x height x width)
90+44+(3n-5)=180
134+(3n-5)=180, subtract 134 from both sides
3n-5=46
3n=51
n=17
To check: 90+44+(3x17-5)=180
