Answer:

z = 49

Step-by-step explanation:

z - 42 = 7

z - 42 = 7

   +42  +42

z = 49

1. add 42 to both sides (adding because its - 42)

2. that leaves us with 7+42 = 49 so z=49

to check your answer u can always plug in 49.

49 - 42 = 7

yup. 49-42 does equal 7.

1. Round this number to the nearest hundred.
navik [9.2K]

Answer:

1. 320   2. 580

Step-by-step explanation:

when you round 320, it is 320 because the hundredths place is 0, which is under 5 so the numbers wouldn't change.

When you round 579, the hundredths place is a 9, which is over 5 so you add 1 to seven to get 8.

Look at picture. Does anybody know the answer I’m lost?

Let x,y be the dimensions of the rectangle. We know the equations for both area and perimeter:

A=xy=36

P=2(x+y)=36 \iff x+y=18

So, we have  the following system:

\begin{cases}xy=36\\x+y=18\end{cases}

From the second equation, we can deduce

y=18-x

Plug this in the first equation to get

xy=x(18-x)=-x^2+18=36

Refactor as

x^2-18x+36=0

And solve with the usual quadratic formula to get

x=9\pm3\sqrt{5}

Both solutions are feasible, because they're both positive.

If we chose the positive solution, we have

x=9+3\sqrt{5} \implies y=18-x=18-9-3\sqrt{5}=9-3\sqrt{5}

If we choose the negative solution, we have

x=9-3\sqrt{5} \implies y=18-x=18-9+3\sqrt{5}=9+3\sqrt{5}

So, we're just swapping the role of x and y. The two dimensions of the rectangle are 9+3\sqrt{5} and 9-3\sqrt{5}
