A company’s profit at the end of the year was -$98.75. Which of these statements must be true?
Hitman42 [59]
The company lost a little less than $100.

Since the number is negative, we know that they lost money. If it was positive, it would've indicated they made money. If they made no money, they would've broken even. This narrows it down to the last two. Since 98 < 100, we know they lost less than $100, which leaves us with the last one.

Chen’s house is 53 years old. This is 5 more than twice the age of Sunny’s house, h.
tankabanditka [31]

Answer:

The Equation which shows the equality is 53 = 2 h + 5 ,

The age of Sunny's house is 24 years old

Step-by-step explanation:

Given as ;

The age of the house of Chen's is 53 years old

Let the age of of the house of sunny = h years old

So, according to question

Chen's house age is 5 years more than twice the age of sunny's house

I.e Chen's house age = 2 × sunny's house age + 5

Or, 53 = 2 × h + 5

or,  2 × h = 53 - 5

so . 2 × h = 48

∴    h = \frac{48}{2} = 24 years

Hence The Equation which shows the equality is 53 = 2 h + 5 , And The age of Sunny's house is 24 years old .  Answer

1/3 + 1/4 + 1/6<br> PLEASE SHOW WORK, thank you
Dovator [93]

Answer:

3/4

Step-by-step explanation:

1/3 + 1/4 + 1/6

notice that the denominators consists of the numbers 3, 4 and 6 and that the lowest common multiple for all 3 numbers is 12, hence all these fractions can be expressed with a denominator of 12

i.e

1/3 = 4/12

1/4 = 3/12

1/6 = 2/12

hence,

1/3 + 1/4 + 1/6

= 4/12 + 3/12 + 2/12

= (4+3+2) / 12

= 9/12  (simply)

= 3/4

What are the intercepts of the equation 4x-6y-5z=60
Annette [7]
To find the intercept of a variable in a equation with more than one variable, you need to equal the others variables to zero.

-> 4x -6y -5z = 60

-> X-Intercept:
To find the X intercept, equal the Y and Z values to 0.
(Y = 0; Z = 0)

4x -6(0) -5(0) = 60
4x = 60
x = 60/4
x = 15

-> Y-Intercept:
To the Y intercept it's the same thing, equal the another variable values to 0.
(X = 0; Z = 0)

4(0) -6y -5(0) = 60
-6y = 60
-y = 60/6
-y = 10        x(-1)
y = -10

-> Z-Intercept:
(X = 0; Y = 0)

4(0) -6(0) -5z = 60
-5z =60
-z = 60/5
-z = 12         x(-1)
z = -12

Answer: The intercepts for this equation (15,-10,-12).
Or: x = 15, y = -10, z = -12.
