Question

Frame the equations and solve them
ii. If z is multiplied by 8 the result is 16​

Answer 1

Answer:

z*8=16

i.e. z8= 16

so here we can see that 8 is in multiply form so if we move 8 from lhs to rhs then it will be 16 divide by 8 so when we will solve it will 2. so therefore, z is replaced by 2 so 2*8=16

$\huge\bold\red{Question}$

• Frame the equations and solve them
• ii. If z is multiplied by 8 the result is 16

$\huge\bold\pink{Answer}$

$\implies$$\small\bold{z×8=16}$

• Hey mate! As it's written to frame the equation so you need to know that framing an equation means writing the sentence in numerical form.

• So as it's given that 'Z multiplied' we get that we have to multiply z with the given number '8' by puting (×) sign between z and 8.

• Then it's given that when they both are multiplied they give 16 as their product. So we have to put an 'equal to' sign between z×8 and 16.

• Which will finally make it z×8=16.

Now solving the equation!

• $\implies$z×8=16
• $\implies$z=16/8
• $\implies$z=2

Varifying!

• $\implies$2×8=16
• $\implies$16=16
• $\implies$0=0

$\text\color{red}{What \: is \: an \: expression?}$

• $\implies$An expression is a combination of constants,variable and mathematical operations.

$\text\color{red}{Constants-}$A fixed value i.e.,any number , such as 1,2,56,100 are all constants because their values are fixed.

$\text\color{red}{Variable-}$A non-fixed value i.e., any letter such as 'a,b,x,n' , etc are variable.
