Solve the two-step equation.-0.45x + 0.33 = -0.66What is the solution?x = -2.2x = -1.4x = 1.4x = 2.2f
Softa [21]

Answer:

x = 2.2

Step-by-step explanation:

-0.45x + 0.33 = -0.66

Subtract .33 from each side

-0.45x + 0.33-.33 = -0.66-.33

-.45x = -.99

Divide each side by -.45

-.45x./-.45 = -.99/-.45

x = 11/5

x = 2.2

Find the value of x in the isosceles triangle shown below
egoroff_w [7]

Answer:

x = 10

Step-by-step explanation:

if there 2 same triangle then they are right triangle

By using Pythagorean theorem for 1 of right triangle, we have

\sqrt{74} ^{2} = 7^{2} + (\frac{x}{2}) ^{2}

74 = 49 + \frac{x^{2}}{4}

74 - 49 = \frac{x^{2}}{4}

25 = \frac{x^{2}}{4}

therefore, x = \sqrt{25*4} = \sqrt{100} = 10
