A number, one-fourth of that number, and one-third of that number are added. The result is 38. What is the original number?

Hatshy [7]

Answer:

Step-by-step explanation:

Let 12x represent the original number.

One fourth of that number can be represented by 3x, and one third of the number can be represented by 4x.

Create an equation that sets this equal to 38, and solve for x:

12x + 3x + 4x = 38

19x = 38

x = 2

The original number is represented by 12x, so plug in 2 as x:

12(2)

= 24

So, the original number is 24.

Please help will give brainly Given h of x equals 2 times the square root x minus 5 end root, which of the following statements

RoseWind [281]

Answer:

The function h(x) is increasing on the interval (5, ∞)

Step-by-step explanation:

$h(x)=2\sqrt{x-5}$

Since we cannot take a square root of a negative number, the domain of this function is restricted to x ≥ 5

If the domain is restricted to x ≥ 5, then the function is always increasing,
since h(x) ≥ 0

Therefore:

The function h(x) is increasing on the interval (5, ∞)

Rectangle ABCD was dilated to create rectangle A'B'C'D. Triangle A B C D is dilated to form triangle A prime B prime C prime D.

MArishka [77]

Answer:

AB=6 Units

Step-by-step explanation:

Given the following lengths of rectangle ABCD and its dilation A'B'C'D' respectively

A'B' = 15 Units
B'C' = 9.5 Units
BC = 3.8 units

We are to determine the length of AB. To do this, we first determine the dilation factor.

$D$ilation Factor =\dfrac{B'C'}{BC} =\dfrac{9.5}{3.8} =2.5$

Therefore:

$\dfrac{A'B'}{AB} =2.5\\\\\dfrac{15}{AB} =2.5\\$Cross multiply \\ 2.5 AB =15 \\AB=15 \div 2.5\\$Therefore, AB=6 Units$
