Construct 3 linear equation starting with qiven solution z = 1/3

Andreyy89

Answer:

(a) $9z+2=5$

(b) $21z-11=-4$

Step-by-step explanation:

We are required to construct 3 linear equations starting with the given solution z = 1/3.

Equation 1

$z=\frac{1}{3}$

Multiply both sides by 9

$9z=\frac{1}{3}\times 9\\9z=3$

Rewrite 3 as 5-2

9z=5-2

Add 2 to both sides

Our first equation is: $9z+2=5$

Equation 2

$z=\frac{1}{3}$

Multiply both sides by 21

$21z=\frac{1}{3}\times 21\\21z=7$

Rewrite 7 as 11-4

21z=11-4

Subtract 11 from both sides

Our second equation is: $21z-11=-4$

Equation 3

$z=\frac{1}{3}$

Multiply both sides by 6

$6z=\frac{1}{3}\times 6\\6z=2$

Rewrite 6z as 4z+2z

4z+2z=2

Subtract 2z from both sides

Our third equation is: $4z=2-2z$

Simora [160]

$\huge\boxed{10}$

$\sqrt{100}$ means that you are looking for the number that, when multiplied by itself, produces $100$ . That number is $10$ , because $10\cdot10=100$ , meaning that $\sqrt{100}=10$ .

How many stones are needed to trade for 10bricks ?

lianna [129]

You need 10 logs for 1 brick. To get 10 bricks you need 100 logs. You are collecting stones and 1 stone gets you 4 logs. That means to get 100 logs you’ll need 25 stones. That indirectly means that 25 stones gets you 10 bricks.
