7 0

Answer:

A, C and D

Step-by-step explanation:

Given

\frac{3}{5}a + 10

Required

Select 3 equivalent expressions

\frac{3}{5}a + 10

Express 3 as 2 + 1

\frac{2 + 1}{5}a + 10

Rewrite as:

\frac{2a + a}{5} + 10

Split

\frac{2a}{5} + \frac{a}{5} + 10 ----- Option (A)

\frac{3}{5}a + 10

Express 10 as 14 - 4

\frac{3}{5}a + 14 - 4

Rewrite as:

14+\frac{3}{5}a  - 4 --- Option (C)

\frac{3}{5}a + 10

Factor out 1/5

\frac{1}{5}(3a + 50) --- Option D

B(1)=16 <br> b(n)=b(n-1)+1 <br> Find the second term in the sequence
anyanavicka [17]

Answer:

17

Step-by-step explanation:

b(n)=b(n-1)+1 means a term can be found by taking it's previous term and adding 1 to it.

So if b(1)=16, the next term b(2)=16+1=17.

Find the measure of the third angle of a triangle given the measure of two angles are 86º and xº.
astra-53 [7]
The total degrees in a triangle is 180. if you add the angles up, it should equal. if we say that the angle of the third angle is y, our equation looks like this
y+x+86=180
if we solve for y, we get
y=180-86-x, which you can solve for for your answer

Un fabricante de ventanas cuadradas cobra a razón de 3 euros por cada metro de marco y 12 euros por el cristal, sean cuales sean
lesya [120]

Answer:

Givens

  • The cost of the square windows is 3 euros per meter, and 12 euros for the crystal.

<h3>If a window has 2 meters side, how much would it cost? (A)</h3>

Notice that the window is a square, that means all four sides are congruent, so it has 8 meters in total, which would cost 24 euros plus the crystal. Therefore, the total cost of a window with 2 meters side is 24+12 = 36 euros.

Specifically, the function of the cost is: C(x)=3x+12, where x represents meters of sides. (C)

<h3>If we paid 60 euros, the dimensions are (B)</h3>

60=3x+12\\60-12=3x\\x=\frac{48}{3}=16

The window has 16 meters between the four sides, which gives 5 meters per side.

The graph of the function is attached.
