Answer:
x = -7
Step-by-step explanation:
5(x-2)=3x+4(x+1)
First, multiply the 5 with the x and the 5 with the -2. You are using the distributive property.
5x -10 = 3x + 4 (x+1)
Then multiply the 4 with the x and the 4 with the 1 on the other side. Again, you are using the distributive property.
5x-10=3x+4x+4
Next, combine like terms. So you're going to combine the 3x and the 4x on the right side.
5x-10=7x+4
Then, subtract 5x from both sides. Also, subtract the 4 from both sides. You do this in order to get all of the x's on one side of the equation.
-14 = 2x
Finally, divide 2 from both sides. You do this because right now, the equation says 2 times x, and you need to get the x alone.
-7 = x
You are finished
Answer:
2:7
Step-by-step explanation:
If 2 of the puppies are brindle that leaves 7 that are not out of the nine making the ratio 2:7.
Twelve and nine thousandths
Step-by-step explanation:
here,,
a=3,b=10,C=120°
c^2=a^2+b^2-2ab cos120°
=(3)^2 +(10)^2 _2 (3)(10)(-1/2) [cos120°=-1/2]
=9+100-(-30)
=109+30
=139
c=(139 )1/2=11.79
c=12
It is the graph of p is steeper than the graph of q.
