The goal is to remove numbers to get X by itself.

1. 9x-5 = 0
(how do we get 9x alone?, ADD five on each side
9x= 5
(how do we get rid of 9?, DIVIDE)
x= 5/9

if you want to get rid of a number, do the opposite!

6x + 4 = 0
- 4 = -4
6x = -4
divide by 6
x = -4/6
now simplify
x = -2/3


7x + 7 = 0
-7. -7
7x = -7
divide by 7
x = -7/7
x = -1

i hope this made sense!!

Rewrite the decimal fraction as a decimal number.
Sergio039 [100]

Answer:

8.025

Step-by-step explanation:

If you count the zeros in 1000, it's three. Count three starting from the back of 25. Add 0 in front of 25 to make it a three digit number. You then put the decimal point with the whole number.

Noah tried to prove that cos(θ)=sin(θ) using the following diagram. His proof is not correct.
alukav5142 [94]

Answer:

The first statement is incorrect. They have to be complementary.

Step-by-step explanation:

You can't say the measure of angle B is congruent to theta because it is possible for angles in a right triangle to be different.

You can only say that what he said is true if the angle was 45 degrees, but based on the information provided it is not possible to figure that out.

The other two angles other than the right angle in a right triangle have to add up to 90 degrees, which is the definition of what it means for two angles to be complementary. A is the correct answer.

How many defective telephones
zhenek [66]

Answer:

Option 3: 300 phones

Step-by-step explanation:

Given

Phone produces each day: 1000

Number of phones that were checked = 30

Defective phones = 9

So the probability of defective phones will be calculated by dividing the number of defective phones by total number of phones checked.

So, the probability of defective phones

= 9/30

= 0.3 or 30%

So, from 1000 phones the defective phones will be:

1000*0.3

= 300 Phones ..
