Answer:
There is 1 solution.
Step-by-step explanation:
0.5(x - 3) = 3x - 2.5
0.5x - 1.5 = 3x - 2.5
-2.5x = -1
x = 0.4
There is 1 solution.
Answer:
x=122/3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6(x+1)(3)−10=740
18x+18+−10=740(Distribute)
(18x)+(18+−10)=740(Combine Like Terms)
18x+8=740
18x+8=740
Step 2: Subtract 8 from both sides.
18x+8−8=740−8
18x=732
Step 3: Divide both sides by 18.
18x

Answer:
x= 122/3
X-4y=-12
4x-y=12
eliminate y's
multily 2nd equaiton by -4 and add to top one
x-4y=-12
<u>-16x+4y=-48 +
</u>-15x+0y=-60
-15x=-60
divide both sides by -15
x=4
sub back
x-4y=-12
4-4y=-12
minus 4 both sides
-4y=-16
divide both sides by -4
y=4
x=4
y=4
(x,y)

The area of a triangle is base x height/2,
so all you have to do is multiply 6x20 to get 120 and then divide that by 2 to get 60 m squared!! :)
Answer:
8x-20
Step-by-step explanation:
Distribute:
=(6)(2x)+(6)(−3)+(−2)(2x)+(−2)(1)
=12x+−18+−4x+−2
Combine Like Terms:
=12x+−18+−4x+−2
=(12x+−4x)+(−18+−2)
=8x+−20
Answer:
=8x−20
