5( 5X – 10) = 15 solve it

olga55 [171]

5(5x-10)=15
5x-10=3
5x=10+3
5x=13
Divide both sides by 5-5 and 5 cancel out to leave you with x 13/5 =2.6
X=2.6

$\text {Hey! Let's Solve this Equation!}$

$\text {The Only Step is to Divide 10:}$

$\text {10y/10=1000/10}$

$\text {Your Answer would be:}$

$\fbox {y=100}$

$\text {Note: When dividing a number by 10 all you gotta do is remove a 0}$ $\text { when it comes to dividing numbers like 1000}$

$\text {Best of Luck!}$

For the line segment whose endpoints are X(1, 2) and Y(6, 7), find the x value for the

finlep [7]

Answer:

3) 2.7

Step-by-step explanation:

The distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ can be determined by:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Since the points are X(1, 2) and Y(6, 7). The distance between the two points is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=\sqrt{(6-1)^2+(7-2)^2}=\sqrt{50}$

the x value for the point located 1/3 the distance from X to Y,

$x=\frac{x_2-x_1}{3}=\frac{6-1}{3}=1.7$

The x value = $x_1+1.7 = 1+1.7 = 2.7$
