joja [24]3 years ago

Step-by-step explanation:

Let, 1st number be x and 2nd number be y

Then,

equation 1

x = 16+y

equation 2

x + y = 120

or, y = 120 - x

now,

x = 16 + y

or, x= 16 + 120 - x (putting the value of y from equation 2 )

or, x + x = 136

or, 2x =136

or, x= 136/2

or, x =68

Then,

y = 120-x

or, y= 120- 68 (putting the value of x)

or, y= 52

Hence, the two numbers are 68 and 52.

William sold half of his comic books and then bought 14 more he now has 24 with how many did he have in the beginning
Lera25 [3.4K]
Let the number of comic books be X
if we add 14 to X = 24
so we will find the value of X to get half initial number of comic books William had.
14+X=24
X=24-14
X=10
so the total innitial number of comic books William had is 10+10=20 books.

Wilson began watering his garden with a watering can that was completely full. The amount of water in the can as Wilson was wate
givi [52]

Answer:

Option B is correct, i.e. The amount of water originally in Wilson's can was 2.5 gallons.

Step-by-step explanation:

Given is the graph of Amount of water (in gallons) v/s Time (in seconds).

It is a linear graph whose general equation is given as follows:-

y=mx+b.

Where y = Amount of water, x = Time, m = slope, b = y-intercept (when time is zero).

Finding slope of line, m = (2.3 - 2.5)/(1 - 0) = -0.2 gallons per second.

Finding y-intercept of line, b = 2.5 gallons (at t=0).

Hence, option B is correct, i.e. The amount of water originally in Wilson's can was 2.5 gallons.

Which equation does not represent a function? Why? A) y = x2; There are two outputs for each input. B) y2 = 4x; There are two ou
natita [175]

Answer:

B) y² = 4x; There are two outputs for each input

Step-by-step explanation:

For an equation to be called a function, the input values for x must only result in a single output for y.

Based on this definition if a function, the functions y = x², y = -x and y = x are all functions because for any value of x imputed in them, we can only get one equivalent value of y.

The only exception is the function y²= 4x

For this function, for any value of x, there will be more than one output for y. Take x = 1 for example

y² = 4(1)

y² = 4

y = ±√4

y = ±2

This shows that y = 2 and -2

Also if x = 4

y² = 4(4)

y² = 16

y = ±√16

y = ±4

y = 4 and -4

No matter the value of x imputed, the output value y will always be two (a positive and a negative value)

Hence, option B is correct.

*Will give brainliest* A ladder, leaning against a wall, makes an angle of 20° with the ground. The foot of the ladder is 3 m fr
Fantom [35]

Answer:

The answer is 3.64m

This is because if you draw a diagram, and label all the sides of the triangle (opp, hyp, adj), the adjacent angle is 3m. You can now use the sine rule to find the hypotenuse (length of ladder) by doing: cos 30= 3/h. You divide cos 30 by 3 and you get the answer of 3.64m rounding to 2 decimal places.
