They aren't equivalent

<h2>Explanation:</h2>

In order to determine whether the expression:

$(5x-20)-(4x-8)$

is equivalent to:

$x$

Genevieve needs to follow these steps:

Step 1. Get rid parentheses

$5x-20-4x+8$

Step 2. Combine like terms

$5x-4x-20+8$

Step 3. Solve

$x-12$

So:

$x\neq x-12$

Therefore, these two expressions aren't equivalent.

Answer:

(a) 8.3 x 4.9 = 40

(b) 12.1 x 2.95 = 36

(c) 60.94 ÷ 5.7 = 10

(d) 32.79 ÷ 3.1 = 11

Step-by-step explanation:

Here, the given expressions are:

Now, here 8.3 can be approximated as 8

4.9 can be approximated as 5.0

So, 8.3 x 4.9 ≈ 8 x 5 = 40

Hence, the suitable estimated product for 8.3 x 4.9 = 40

Now, here 12.1 can be approximated as 12.

2.95 can be approximated as 3.0

So, 12.1 x 2.95 ≈ 12 x 3 = 36

Hence, the suitable estimated product for 12.1 x 2.95 = 36

Now, here 60.94 can be approximated as 61.

5.7 can be approximated as 6

So, 60.94 ÷ 5.7 ≈ 61 ÷ 6 = 10 . 16

Hence, the suitable estimated quotient for 60.94 ÷ 5.7 = 10

Now, here 32.79 can be approximated as 33.

3.1 can be approximated as 3.

So, 32.79 ÷ 3.1 ≈ 33 ÷ 3 = 11

Hence, the suitable estimated quotient for 32.79 ÷ 3.1 = 11

Cos³x.tan²x - cosx = ?

melamori03 [73]

tan x = sin x/cos x

cos³ x *tan²x - cos x = cos³x *(sin²x/ cos² x) - cos= cosx*sin²x - cos x =

= cos x(sin² x - 1) = - cos x(1 - sin²x)= - cosx*cos²x = - cos³ x

I need help with this ASAP!!!!!

Answer:

x=3

Step-by-step explanation:

∠DBC+∠VBC is 180° since it is a straight line, ∠VBC=20x+5

The sum of all angles in a triangle is 180°, 9x-2 + 40° +∠DBC=180°

To find x, you can find ∠DBC first. *Don't forget BRACKETS

∠DBC=180-(20x+5)

∠DBC=180-(9x-2 + 40°)

Now equal the equations to each other to find x.

180-(20x+5)=180-(40+9x-2)

180-20x-5=180-40-9x+2

175-20x=142-9x

175-142=20x-9x

33=11x

x=33/11

∴x=3
