Answer:

1.3

Step-by-step explanation:

BC is the distance between B and C.

BC = x − (-0.4)

BC = x + 0.4

AB is the distance between A and B.

AB = -0.4 − (-1.25)

AB = -0.4 + 1.25

AB = 0.85

Substitute into the equation.

BC = 2AB

x + 0.4 = 2(0.85)

x + 0.4 = 1.7

x = 1.3

use the distance formula to find the distance, to the nearest tenth, between each pair of points (4,5) and (0,2)

Pavlova-9 [17]

Let us use the formula with the point (4,5) and (0,2)

$\begin{gathered} d=\sqrt[]{(x_1-x_2)^2+(y_1-y_2)^2}=\sqrt[]{(4-0)^2+(5-2)^2} \\ =\sqrt[]{16+9}=\sqrt[]{25}=5 \end{gathered}$

A number is 5 more than 3 times another number. The sum of the two numbers is 33. As an equation, this is written x + 3x + 5 = 3

Cloud [144]

Answer:

x=7, so the smaller number is 7 and the larger number is 21.

Step-by-step explanation:

x=3x+5=33

Let x=3:

(3)+3(3)+5=3+9+5=17, not 33, so x is not 3

Let x=5:

(5)+3(5)+5=5+15+5=25, not 33, so x is not 5

Let x=7:

(7)+3(7)+5=7+21+5=33, so x=7

Let x=9:

(9)+3(9)+5=9+27+5=41, not 33, so x is not 9

Therefore x=7. Because x represents the smaller number, and the larger number is 3 times the smaller number, the smaller number is 7 and the larger number is 3(7)=21.

Please help!!!

trasher [3.6K]

When an answer to a question uses the greater than symbol, that means any number above the number used is a possible answer to the equation. However, when it's just a simple "x = 2", then 2 is the only possible answer to that equation. Think about it as if it were on a graph. In the attached file I have a graph that is displaying the equation "x > 4". The entire shaded area to the right of 4 could be a possible answer.

Hope this helps.
