Answer:
the answer to the question is 50 m.
It is a linear simple equation for one unknown, lets solve it!
-4.2x + 31.5 = -65.1
we can easily get rid of decimals if we multiply the whole equation times 10:
<span>-42x + 315 = -651
</span>-42x = -651 - 315 = -966
x = 966/42
x = 23
that is the solution
Answer:$17,260 is how much more he will have to earn to pay for his degree!
Step-by-step explanation:First you have to multiply 7,215 with 4 and you get 28,860.Next you multiply 1,350 by 4 and you get 5,400.Then you add 5,400+4,200+2,000 and you get 11,600.Last but not least,you subtract 11,600 with 28,860 and you get $17,260!
Answer:
The last one is the answer.
Answer:
9,11
Step-by-step explanation:
let the numbers be x, x+2 (since consecutive odd integers have a difference of 2)
therefore;
x(x+2)= 99
x²+2x=99
I usually solve the sum like this,
we need to find the nearest square number ( number smaller than the number on the R.H.S)
here, it is 81, whose square root is 9. therefore the solution is 9
verification:
(9)²+2*9=99
81+18=99
99=99
hence, 9 is the solution. therefore the positive odd consecutive integers are
x=9
x+2=9+2= 11
verification:
9*11=99
99=99
L.H.S=R.H.S
