30/100=3/10
3 divided by 21 = 7
7*10 = 70!
The anwser is $70 I hoped that helped :3
Answer:
-(18/49)=n or approximately n=-0.367
Step-by-step explanation:
our equation is: m(nx²-y)/z=5n in order to find n we need to substitute the values given in the question. when we substitute we get:
6*(n*(-2)²-(-3))/(-5)=5n
6(4n+3)/(-5)=5n (we distribute the 6 in the numerator)
24n+18/-5=5n (we multiply both sides by (-5))
24n+18=-25n (we subtract 24n from both sides)
18=-49n (divide both sides by (-49))
-(18/49)=n or approximately n=-0.367
Answer: x = 10.3 ÷ 4
Step-by-step explanation: if we were to work this out forgetting about the equation it can be worked out by dividing the 10.3 by 4 to find the length of the pieces so, now to express it as an equation, we have to add x into our sum 4 × ? = 10.3 : 4x = 10.3. The answer for x would be x = 2.58.
Answer: 4/-2
Step-by-step explanation:
rise/run
it rises up 4 which is positive and then it goes left 2 which makes the 2 negative since its going to the left
