Consider this equation.


7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)



Mia solved the equation and determined that m = 2. Is she correct?

She is incorrect because when substituting 2 for m the result was a true statement.

She is incorrect because when substituting 2 for m the result was a false statement.

She is correct because when substituting 2 for m the result was a true statement.

On Monday morning Sergio Pappas had $14.78 in cash.
During the week he earned $45.00 for cutting lawns
and $35.75 for yard work, and he spent $25.23 on food
and $22.12 on gas.
# Problem Solution
a. What were Sergio's total earnings for the week?
b. What total amount did he have to spend during the week?
c. What was his balance at the end of the week?

( please do not comment if you do not know the answer, would be appreciated )

Answers

Answer:

Step-by-step explanation:

a-As he had earned $45.00 for cutting lawns and had earned $35.75 for yard work during the week and had not earned more than that, in order to find the total amount of money he earned during the week, we have to add $45.00 and $35.75 together which will be $80.75. So we can say that he had earned $80.75 during the week.

b- Since he had spent $25.23 on food and $22.12 on gas, we have to add them to get the total amount of money spend during the week. So after adding the amount of moneys spent, we will get $47.35.

c- Finally, to find out how many money he was left with, we have to subtract the amount of moneys spent from the total amount of earnings for the week. So, after subtracting $47.35 from $80.75 he is left with $33.4.

Tap A fills 10/11 of a bottle in a minute. Tap B fills 3 4/5 times as many bottles as Tap A in a minute. Find the number of bottles Tap B fills in a minute.

Answers

Answer:

  3 5/11

Step-by-step explanation:

Tap A's rate is (10/11) bottle/min.

Tap B's rate is 3 4/5 = 19/5 times that of tap A. Then tap B's rate is ...

  (19/5)(10/11) bottles/min = 38/11 bottles/minute

Tap B fills 3 5/11 bottles in a minute.

An angle measures 143.4° less than the measure of a supplementary angle. What is the measure of each angle?

Answers

Given :-

Measure of an angle = x

Measure of another angle = x - 143.4

Each angle is the supplement of the other angle .

Which means :-

[tex]x + x - 143.4= 180[/tex]

[tex]2x - 143.4 = 180[/tex]

[tex]2x = 180 + 143.4[/tex]

[tex]2x = 323.4[/tex]

[tex]x = \frac{323.4}{2} [/tex]

[tex]\color{hotpink}x = 161.7[/tex]

Then :-

Measure of the first angle :-

[tex]\color{hotpink} = 161.7°[/tex]

Measure of the second angle :-

[tex] = x - 143.4[/tex]

[tex] = 16.7 - 143.4[/tex]

[tex]\color{hotpink} = 18.3°[/tex]

As the sum of the measure of each angle adds up to 180° (161.7+18.3=180) , we can conclude that we have found out the correct value of each of the angles .

Therefore , the measure of the first angle is = 161.7° and the measure of it's supplementary angle is = 18.3° .

The suspect was spotted riding the swings earlier in the day. Each swing can hold a maximum weight of 500 pounds. In order to reach the maximum weight, you would have to double the weight of the suspect and add 20 pounds less than the weight of George. Write and solve an equation to represent the suspect's weight.

Answers

Answer:

2y + ( x- 20)= 500

y= 520-x/2

Step-by-step explanation:

Let the weight of George be x and the weight of the suspect be y .

The swing can hold a maximum of 500 pounds .

Twice the weight of suspect added with 20 pounds less than the weight of George equals 500.

2y + ( x- 20)= 500

or

2y+x- 20 = 500

adding 20 to both sides

2y+x -20 +20= 500+ 20

or

2y +x = 520

Subtracting x from both sides

2y+ x-x = 520-x

or

2y = 520-x

Dividing by 2 on both sides

y= 520-x/2

The suspect's weight is y= 520-x/2

Answer:

s = 260 - g/2

Step-by-step explanation:

Given the following :

Maximum weight swing can hold = 500 pounds

Let suspect's weight = s

George's weight = g

To reach maximum weight :

Double weight of suspect + (George's weight - 20)

Hence, equation:

2s + (g - 20) = 500

2s + g - 20 = 500

2s + g = 500 + 20

2s + g = 520

2s = 520 - g

Divide through by 2

s = 260 - g/2
