1. Start your equation by making lines like this
- = -
2.On the top right side put x
3.On the bottom right side put 85
4. On the top left side put 3
5.On the bottom left side put 100
6. It should look like this
3 = x
- -
100 85
7. Cross multiply ( 100 times x equals 100x and 3 times 85 is 253 )
8. Divide both by 100 (100x divided by 100 equals 1x and 253 divided by 100 is 2.53)
9. Add 2.53 to 85 (getting 87.53)
10. The answer is: The cost of their TV service is $87.53

17. Classify Each Angle Pair then find the value of X

IRISSAK [1]

Given -

If l || m, m∠1 = (13x + 24)°, and m∠2 = (5x-6)°,

To find -

m∠2.

Concept -

Whenever two parallel lines are cut by a transversal, an interesting relationship exists between the two interior angles on the same side of the transversal. These two interior angles are supplementary angles. Hence, according to the figure l and m are two parallel lines and t is the transversal intersecting them then ∠1 + ∠2 = 180°.

Solution -

$\rightarrow\sf{(13x+24)^{ \circ}+(5x-6)^{ \circ}=180^{ \circ}}$

$\rightarrow\sf{13x+5x+24-6=180}$

$\rightarrow\sf{18x+18=180}$

$\rightarrow\sf{18(x+1)=180}$

$\rightarrow\sf{x+1=\frac{180}{18}}$

$\rightarrow\sf{x+1=10}$

$\rightarrow\sf{x=10-1}$

$\rightarrow\boxed{\bf{x=9}}$

m∠2 = (5x-6)° = {5(9) - 6}° = {45 - 6}°= 39°

Henceforth, m∠2 = 39°

If f(x)=7x-6 which of the following is the inverse of (x)?

Vedmedyk [2.9K]

Here we have , f(x) = y= 7x-6

To find the inverse function of the given function, we need to follow some steps, which are:

First we need to switch x and y, that is

x= 7y-6

Next step is to solve for y, and for that, we need to add 6 to both sides

x+6=7y

Dividing both sides by 7, that is

$y = \frac{x+6}{7}$

Therefore,

$f^{-1}(x)= \frac{x+6}{7}$

Additional inverse of 5.5

Anika [276]

Answer: 5.5 + (-5.5)=0 this making the opposite of positive 5.5, (-5.5).

(Let me know if this helped, I hope I didn’t make a mistake)

Step-by-step explanation:

example, the additive inverse of the positive number 5 is -5. That's because their sum, or 5 + (-5) = 0

5 biscuits cost 30p altogether how much do 7 biscuits cost?

andrezito [222]

First we want to find how much an individual biscuit costs.
If 5 biscuits costs 30p, then
5 x 1 biscuit = 30p
divide both sides by 5
1 biscuit = 6p

If one biscuit costs 6p, and we want to know how much 7 biscuits cost, then:

7 x 6p =42p

7 biscuits costs 42 p
