patriot [66]
You will have to divide 353 millimeters by 4:

353 ÷ 4 = 88.25

now we have to multiply 88.25 by 9 (5+4), the total millimeters of only one portion of this drug

88.25 x 9 = 794.25

So he will make 794.25 millimeters of drug (that is if he has the part a too)

(If you should round 88.25 to 88, the answer would be 88 x 9 = 792)

<h2>Answer:</h2>

  • option (c) = -19 + x = -21

<h2>Step by step explanation:</h2>

<u>Question</u> : A number added to -19 is -21

<h3><u>Solution</u> ↓</h3>

First of all to make equation

Equation means LHS = RHS

For eg we take :-

50 - 20 = 10 + 20

30 = 30

Therefore, LHS = RHS

<h3>According to the question :</h3>

  • Which number would we add in -19 to get -21 and we get LHS = RHS

Make an equation

-19 + x = -21

x = -21 + 19

x = -2

Add -2 in the variable of x

Variable means any unknown value we used in maths. For eg :- x,y,z,a,b,c,p,q,r etc.

-19 + (-2) = -21

-19 - 2 = -21

-21 = -21

Therefore, LHS = RHS.
