3.9x + 1.4 = 17 what is the steps​

Mathematics
1 answer:
Vedmedyk [2.9K]3 years ago
6 0

Answer:

x=4

Step-by-step explanation:

3.9x + 1.4 = 17

Having a decimal is not very nice to deal with, so we multiply all sides by 10 to get rid of the decimals.

3.9x*10+1.4*10=17*10

39x+14=170

Subtract 14 from both sides:

39x+14-14=170-14

39x=156

Divide both sides by 39:

\frac{39x}{39}=\frac{156}{39}

x=4

In the figure, we can consider that the base is the side that mesures 12 in and that the height is the side that measures 15 in, since that sides are perpendicular. So, we just need to use the given formula:

A = \dfrac{bh}{2}\Longrightarrow A = \dfrac{12\cdot15}{2}\Longrightarrow A=6\cdot15\Longrightarrow \boxed{A = 90~\text{in}^2}

Hence, the area of the triangle is 90 in² (B).

If triangle RST and triangle XYZ are similar, which of these equations must be true?
Delicious77 [7]

Answer: A

Step-by-step explanation:

If they are similar, that means the proportions for corresponding sides will be the same.

          I personally ignore the picture and use the labels of "triangle RST and triangle XYZ" that the problem gives <em>because</em> the XYZ picture is not lined up with the similarity it has with RST.

(A) says that side ST is corresponding with side YZ,

          [] Triangle R<u>ST</u> and triangle X<u>YZ</u>

          -> Correct

(A) also says that side RT is corresponding with size XZ,

          [] Triangle <u>R</u>S<u>T</u> and triangle <u>X</u>Y<u>Z</u>

          -> Correct

               This means that option A is the correct answer.
