Answer: 48 minutes
I just took the test and got it right.
Answer:
Step-by-step explanation:
Sum of all angles of triangle = 180°
15x + 3 + 3x - 1 + 52 = 180
15x + 3x + 3 - 1 + 52= 180
Combine like terms.
18x + 54 = 180
To find the vlaue of x, we have to islolate x
<u>Step1:</u> Subtract 54 from both sides
18x = 180 - 54
18x = 126
<u>Step2:</u> Divide both sides by 18
x = 126/18
x = 7
Answer:
4 2/6 = 3 8/6
Step-by-step explanation:
Convert the given mixed fractions to improper fractions.
( 4 × 6 ) + 2 ) / 6 = 26/6
( 3 × 6 ) + 8 ) / 6 = 26/6
Therefore, these are equivalent.
Answer:
That is a quadratic equation and they always have TWO solutions.
And the zeroes occur at:
x = -0.58579 and x = -3.4142
