Two trains, train a and train , weigh a total of 466 tons. Train A is heavier than train b. The difference of there weights is 326 tons. What is the weight of each train

Answers

Answer 1

Answer: A = 396 tons

B = 70 tons

Step-by-step explanation:

From the question,

Weight of A + Weight of B = 466

Weight of A - Weight of B = 326

A + B = 466 ......... i

A - B = 326 ..........ii

Subtract equation ii from I

2B = 140

B = 140/2

B = 70 tons

A = 466 - 70

A = 396 tons

Do i need to flip my sign 3x>12

Answers

Answer:

divide three from both sides to get x > 4

Answer:

No

Step-by-step explanation:

You only need to flip your sign when dividing by a negative. 3x > 12 = x > 12/3 = x > 4. If the equation were -3x > 12, then it would be x < 4.

) Your father uses text messaging to communicate with his employees. If he sends an average of 19 text messages each day, how many more text messages does he send than you? Write an equation and solve for the unknown value. (2 points)

Answers

Answer:

father sends 7 more

Step-by-step explanation:

19-12=7

The equation representing the situation is x = 19 - 12 and the value of x is 7.

What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that,

Number of text messages that your father sends a day = 19

Number of text messages that you sends a day = 12

The equation that represents how many more text messages father sends than you is,

x = 19 - 12

where, x represents the number of text messages that your father sends more.

Solving this, we get,

x = 7

Hence father send 7 more messages than you.

please help solve for y

Answers

Answer:

[tex]y = \frac{-3}{4}[/tex]

Step-by-step explanation:

[tex]\frac{y}{2} + \frac{1}{4} = \frac{y}{6}[/tex]

Lets take all the variable terms in L.H.S & all the constant terms in R.H.S.

(While taking a term from one side to another side , it's sign changes )

⇒ [tex]\frac{y}{2} - \frac{y}{6} = -\frac{1}{4}[/tex]

Now in L.H.S. , lets solve the fractions and reduce its numerator and denominator .

⇒  [tex]\frac{3y - y}{6} = -\frac{1}{4}[/tex]

⇒  [tex]\frac{2y}{6} = -\frac{1}{4}[/tex]

⇒  [tex]\frac{y}{3} = -\frac{1}{4}[/tex]

Lets multiplying 3 on both the sides .

⇒  [tex]\frac{y}{3} \times 3 = -\frac{1}{4} \times 3[/tex]

⇒  [tex]y = \frac{-3}{4}[/tex]

Given the function below, evaluate h(c) for c = 5
h(c) = 6c² - 76 - 2

Answers

Answer:

72

Step-by-step explanation:

Substitute c = 5 into h(c) , that is

h(5) = 6(5)² - 76 - 2 = 6(25) - 78 = 150 - 78 = 72

Plug in five to the equation, for example: h(5)=6(5) squared -76-2 5 squared is 25 6x25=150 ... 150-76-2=72.... h(5)=72 divid both sides by 5 to find the value of “h” (h=14.4)

Jason purchased three different sizes of candy at the store. The
medium candy was twice as expensive as the small candy. The large
candy was $5 more than the medium candy. He spent a total of $30 on
candy. Write and solve an equation to determine the cost of the small
candy.

Answers

Answer: $5

Step-by-step explanation:

Let the small candy be represented by x.

The medium candy was twice as expensive as the small candy. This will be: = 2×x = 2x

The large candy was $5 more than the medium candy. This will be: = 2x + 5

Since Jason spent a total of $30 on

candy, the cost of the small candy will be:

x + 2x + 2x + 5 = 30

5x + 5 = 30

5x = 30 - 5

5x = 25

x = 25/5

x= 5

The small candy cost $5
