17. (x^2-x+3)(4x+1)
18.(x+2)(x) - (7)(3)
Step-by-step explanation:
Let's simplify step-by-step.
16−3+3q−1.7+−13p+4
=16+−3+3q+−1.7+−13p+4
Combine Like Terms:
=16+−3+3q+−1.7+−13p+4
=(−13p)+(3q)+(16+−3+−1.7+4)
=−13p+3q+−0.533333
Answer:
=−13p+3q−0.533333
Set the two "y='s" to each other and then solve for x.
To start it off you would do this: 6x-2=-6x+6
Then you would isolate x and get your answer.
In the second equation:
Subtract 8x from both sides.
2z = 22 - 8x
Divide 2 on both sides.
z = 11 - 4x
Plug this into the first equation.
-66 - 2(11 - 4x) = -196
-66 - 22 + 8x = -196
Combine like terms.
-88 + 8x = -196
Add 88 to both sides.
8x = -108
Divide 8 on both sides.
x = -13.5
Put this into the second equation.
8(-13.5) + 2z = 22
-108 + 2z = 22
Add 108 to both sides.
2z = 130
Divide 2 on both sides.
z = 65
and
x = -13.5
Hope this helps!
Answer:
27.75₁₀
Step-by-step explanation:
Convert binary 11011.110 to base 10
11011.110 = 1*2^4 + 1*2^3+0*2^2 + 1*2^1 + 1* 2^0 + 1*2^-1 + 1* 2^-2 + 0
11011.110 = 16+8+0+2+1+1/2+1/4
11011.110 =27 + 3/4
11011.110 = 27.75₁₀
Hence the binary number to base 10 is 27.75₁₀
