Question

WILL GIVE FAN AND MEDAL! Tell whether the given number is a solution of each equation.
74. 9 = 2a + 3; 3 76. 4.4r – 2.8 = 1.6; 1

Answer 1

Please help! @mathmale

Answer 2

they are 2 different equations

Answer 3

Next time, please type in only one problem at a time.
Do you mean
74. 9 = 2a + 3; 3?

Answer 4

Yes. :)

Answer 5

for each question plug in the given value in place of the variable and see if both sides are equal
and yeah post each question separately...

Answer 6

Then please substitute the value 3 for the letter a.
Is the resulting equation true or false?

Answer 7

Is 9 = 2(3) + 3 true or false?

Answer 8

both are correct

Answer 9

OK. Is 3 a solution of the first equation?

Answer 10

What? 9 is

Answer 11

No. think what "solution" means. You are substituting the value 3 for the variable 'a' in the first equation. When you do that, you find that the equation is true. We say that 3 is a ... ? of the equation.

Answer 12

yes

Answer 13

Please provide the missing word. The first equation is true if we substitute a = 3. We therefore call a = 3 a " ....................... " of the equation.

Answer 14

variable

Answer 15

a is a variable, yes. But what do the instructions for this problem as you to do?

a = 3 is a particular value of the variable 'a'. since the equation is true when a = 3, we call that a = 3 a " ................ " of the equation. Go back and read the problem statement, please.

Answer 16

given number

Answer 17

solution

Answer 18

Yes. Take my word for this: you have to understand that word "solution" as you will see it again and again in math.

Answer 19

r = 1 is a " ............... " of ..... ?

Answer 20

What happens when you substitute r = 1 into the second equation?

Answer 21

whatttttttttttttttt

Answer 22

Same thing as before. If you substitute r=1 into the second equation, the equation is true. That's what you yourself told me. Therefore, we call r = 1 a ' ................ ' of ... what ... ?

Answer 23

i give up

Answer 25

Please substitute r =1 into 4.4r – 2.8 = 1.6. (You have done this before.) Is the equation now true or false?

Answer 26

When you respond, I will also. Since you're not responding at the moment, I'm leaving this problem temporarily to look at problems posted by others.
