Identify the property of equality that makes the Equation 1 and Equation 2 equivalent

Mathematics
1 answer:
Otrada [13]3 years ago
6 0

Step-by-step explanation:

<u>To make both equivalent</u>.

For equation (I) multiply all through by 4

Now, from

x - 1/2 = x/4 + 3

it becomes

4(x) - 4(1/2) = 4(x/4) + 4(3)

--> 4x - 2 = x + 12.

This is your new equation (I) or you can call it equation (iii).

For equation (ii) multiply all through by 1 to make it equivalent to your new equation (I) or eqn (iii) if you wish.

Now from

4x - 2= x + 12

it becomes

1(4x) - 1(2) = 1(x) + 1(12)

--> 4x - 2 = x + 12

This is your new equation (ii) or you can call it equation (iv)

Therefore;

Equation 1 has to be multiplied by 4 and Equation 2 by 1 to make both equivalent.

New equation 1 is 4x-2=x+12

New equation 2 is 4x-2=x+12.

Bottle A contains 4 ounces of water, which is 25% of the amount of water in Bottle B. How much water is there in Bottle B?
sveticcg [70]

Answer:

B=16 ounces

C=24 ounces

B=1/0.75=133%

Step-by-step explanation:

we have that

A≡0.25B (25%), if A=4 ounces  then B=4/0.25 = 16 ounces

C=1.5B (150%), if B=16 ounces then C=1.5*(16 ounces) = 24 ounces

D≡xB (?%), if D=12 ounces then x=12/16 = 0.75 ≡ 75%, but xB≡D ⇒ B≡D/x →

B≡12(1/0.75)= B=12*(1.333)→ B≅133%D

An average of 20 apples were sold from Monday to Friday. After the sales on Saturday and Sunday, the average apples sold per day
avanturin [10]
131 apples were sold on Saturday and Sunday.

Work:
Monday - Friday : 5 days
20 x 5 = 100 apples

Monday - Sunday: 7 days
33 x 7 = 231 apples

231 - 100 = 131

How do I do this? 50 points, please answer
xz_007 [3.2K]

Check the picture below.

now, the midsegment of a triangle, besides being half the base, we have to bear in mind that is a "mid" segment, is a segment that lies half-way along the segments it touches.

so for the triangle above, well, the midsegment DE is cutting the segment BC it two equal halves, BE and EC, that means that \stackrel{x}{BE}~~ = ~~\stackrel{8}{EC}.

7.) Nate has $267 in bills. None of the bills is greater than $10. He has eleven $10 bills. He has seven fewer $5 bills than $1
slavikrds [6]
Just set up 2 equations. 

267 = 10(11) + 5(x) + 1(y) 
x = y - 7 

you can plug the second into the first and get 

267 = 110 + 5(y - 7) + y 
157 = 5y - 35 + y 
6y = 192 
y = 32 
x = 32 - 7 = 25 

thus, 32 $1's and 25 $5's
