Select the three expressions that are equivalent to 3/5a + 10

Sonbull [250]

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

In the triangle below, y= . Round to the nearest tenth

horsena [70]

Use cosine.

$cosine={adjacent}{hypotenuse}$

We have:

adjacent = 9cm and hypotenuse = 17 cm

$\cos x=\dfrac{9}{17}\approx0.5294\to x\approx58^o$

I need help finding missing angles

Citrus2011 [14]

Answer:

1 = 128 degrees

2 = 52 degrees

3 = 47 degrees

4 = 133 degrees

5 = 81 degrees

Step-by-step explanation:

angle 2 and 52 degrees are corresponding angles so they are equal.

angle 3 and 47 degrees are corresponding angles so they are equal.

angles 1 and 2 are supplementary angles so their sum is 180 degrees.

angles 3 and 4 are supplementary angles so their sum is 180 degrees.

angle 5 = 180 - 52 - 47 = 81 degrees
