<em>(-4/9)*3×(-27/20)*4=</em><em> </em><em>7</em><em>.</em><em>2</em>
Answer:
The estimate is reasonable.
Step-by-step explanation:
Jamie's estimate seems reasonable.
We can see that there is (-24/27) in the bracket, first of all there is negative sign so there will be negative sign in the answer. Moreover, 24 is near to half of 27 so fraction will result in -0.5XXXXX and multiplying it with 1.4 will increase it around -0.75.
We can solve the given fraction for confirmation,
So,
which is near to -0.75 so the estimate of Jamie was right ..
Answer:
1/5
Step-by-step explanation:
start with 40/200 and simplify it. they can both be divided by 40, so 40 divided be 40 is 1 hence the numerator, and 200 divided by 40 is 5, the denominator. Hope this helps !! :)
I don't understand your question but:
(x + 5)(x + 2)
= x^2 + 5x + 2x + 10
= x^2 + 7x + 10
Answer:
The first is 3 and the second is 18
Step-by-step explanation:
Let the first number be x and the second number be 6x
The sum of the two is 21 which means
x+6x= 21
7x=21
Divide both sides by 7
X=3
And the second number is six times the first which means
6(3)=18
Therefore,the first number is 3 and the second number is 18
