Answer:
x = 35768.595041
Explanation:
0.043x − 0.0116x+0.007x + 0.01x = 1731.2
Simplify both sides of the equation
0.043x − 0.0116x + 0.007x + 0.01x = 1731.2
0.043x - 0.0116x + 0.007x + 0.01x = 1731.2
(0.043x − 0.0116x + 0.007x + 0.01x) = 1731.2(Combine Like Terms)
0.0484x = 1731.2
0.0484x = 1731.2
Divide both sides by 0.0484
0.0484x / 0.0484. = 1731.2/0.0484.
x = 35768.595041
Step-by-step explanation:
we cannot "solve" it, as we don't know anything about y or k, by we can "simplify" it.
as multiplication is commutative, we can split the whole expression into multiplication factors, simplify each factor, and then out the results back together as one large multiplication.
and remember for the simplification of exponents, multiplying terms with the same base means adding the exponents, dividing terms with the same base means subtracting the denominator exponent from the numerator exponent.
and a^-b = 1/(a^b).
so, we could see the main expression as
(-4/-8)×(y⁶/y⁹)×(k²/k⁵)
(-4/-8) = 1/2
(y⁶/y⁹) = y^-3 = 1/y³
(k²/k⁵) = k^-3 = 1/k³
because e.g.
y⁶/y⁹ = (y×y×y×y×y×y)/(y×y×y×y×y×y×y×y×y) = 1/(y×y×y)
putting the results back together gives us
1/2 × 1/y³ × 1/k³ = 1/(2y³k³)
The answer is x=40.
you subtract 80 from 180 to get the sum of y and 60, which is 100. because y doesn’t include the 60 degrees, you subtract 60 from 100.
then, you get 40 for y. because x is a vertical angle of y, you get 40 for x as well since they’re congruent to each other.
