Step-by-step explanation:
7x = 2x + 5
7x - 2x = 5
5x = 5
x = 1

Step-by-step explanation:
The statement is 3 multiplied by 2/3. Here, the first no of 3 and the other one is 2/3.
It can be written as follows :
![3\times \dfrac{2}{3}](https://tex.z-dn.net/?f=3%5Ctimes%20%5Cdfrac%7B2%7D%7B3%7D)
3 is present at the numerator as well as the denominator. It will cancel out.
So,
=2
So, 3 multiplied by 2/3 equals 2.
Answer:
$6,750
Step-by-step explanation:
5% × $135,000 = 5/100 × 135,000
= $6,750
Consider this option:
1. given: n(A;B;C)=n(-5;-4;-1) and A(-1;-5;-2)=A(x₀;y₀;z₀).
Common view of equation for a plane is Ax+By+Cz+D=0, where A,B,C,D - numbers.
2. from another side using coordinates of A and normal vector it is possible to make up the equation: A(x-x₀)+B(y-y₀)+C(z-z₀)=0 ⇒ -5(x+1)-4(y+5)-(z+2)=0; ⇒ -5x-4y-z-27=0 or 5x+4y+z+27=0.
