x + 7 = 2(3x - 4) Remove the brackets
x + 7 = 2*3x - 4*2
x + 7 = 6x - 8 Subtract 7 from both sides.
x + 7 - 7 = 6x - 8 - 7
x = 6x - 15 Subtract 6x from both sides
x - 6x = - 15
-5x = - 15 Divide by -5
-5x/-5 = -15/-5
x = 3
Answer:
($0.5 x 2) + ($1.25 x 3) + ($0.75 x 3) = $7
Answer= 18
Explanation: you have to graph it on a grid paper first then make. Also trust me it’s the answer
Answer:
C
Step-by-step explanation:
The vertex form of the equation of a circle is 
where (h,k) is the center of the circle and r is the radius. This means that for the circle with center (-3,1) and radius 5 substitute into the vertex form these values. Substitute h = -3, k= 1, and r = 5. The equation becomes 
. This simplifies to 
. The solution is C.
