2 for number 1, 3 for number 2
Step-by-step explanation:
1/2 or 0.5×4=2 and 3/4 or 0.75×4=3
Answer:
The answer is C. 8x-2
This is because the total no. Of jars is 8 x no. Of boxes = 8x
2 jars are removed
So what is left over is y = 8x - 2
Hope this helps!
Answer: x = 40
<u>Step-by-step explanation:</u>
3x + x + 20 = 180 <em>same side (consecutive) interior angles</em>
4x + 20 = 180
4x = 160
x = 40
****************************************************************************
Answer: x = 24
<u>Step-by-step explanation:</u>
6x - 24 + 2x + 12 = 180 <em>linear pair (supplementary angles)</em>
8x - 12 = 180
8x = 192
x = 24

Answer: x = 16
<u>Step-by-step explanation:</u>
base angles of an isosceles triangle are congruent
2(2x + 15) + 6x - 10 = 180 <em>triangle sum theorem</em>
4x + 30 + 6x - 10 = 180
10x + 20 = 180
10x = 160
x = 16
****************************************************************************
Let ∠1 and ∠2 represent the exterior angles in the diagram and "x" represent the same side (consecutive) interior angle with ∠1.
Then m∠1 + x = 180 <em>same side interior angle theorem</em>
and m∠2 + x = 180 <em>linear pairs are supplementary </em>
m∠1 + x = m∠2 + x <em>transitive property</em>
m∠1 = m∠2 <em>subtraction property of equality</em>
∠1 ≈ ∠2 <em>definition of congruency</em>
So, for the area of a circle, there should be a line in the middle. Correct?
Well, that line is the diameter. Then cut that in half, so if the diameter is 6, the radius is 3.
Then multiply the the radius by the radius, so 3x3 once you get that, multiply the answer by pi. Pi= 3.14, so if you do 3x3x3.14 you should get 28.26. Hope this helps.
Answer:
Coach pug charges $45 only one time, and an additional of $20 per session.
So if you take x sessions, the total cost will be:
c(x) = $45 + $20*x
Dr. Doberman charges only $30 per session, then the cost for x sessions will be_
d(x) = $30*x
Now, which one is better for you?
We need to see the value of x such that:
d(x) = c(x)
$30*x = $45 + $20*x
$30*x - $20*x = $45
$10*x = $45
x = $45/$10 = 4.5
This means that if you take 4 sessions or less, is better the Dr. Doberman, because in this case we do not have an y-intercept.
If you want to have 5 sessions or more, is better Coach Pug, because the slope of the equation is smaller, so the costs for larger values of x will be smaller.
