Answer:
<h2><u><em>
the second one.</em></u></h2>
Step-by-step explanation:
All we are going in this situation is to take the values for x which they provided and substitute it for the x and solve to get the value for y.
y = x - 5 y = x - 5 y = x - 5
y = -2 - 5 y = 1 - 5 y = 8 - 5
y = -7 y = -4 y = 3
(-2, -7) (1, -4) (8, 3)
The angles are B and C.
The three angles add up to 180º
A=80º
B
C
A+B+C=180º
80º+B+C=180º
B+C=180º-80º
B+C=100º (1)
The ratio between A and B is 7/13 ; therefore:
B/C=7/13 ⇒B=7C/13 (2)
With the equations (1) and (2), we make a system of equations:
B+C=100
B=7C/13
We can solve this system of equations by substitution method:
7C/13 + C=100
least common multiple=13
7C+13C=1300
20C=1300
C=1300/20
C=65
B=7C/13
B=7*65/13
B=455/13
B=35º
Answer: The measures of those two angles are 65º and 35º.
Answer:
$300
Step-by-step explanation:
Since 20% is equal to 1/5, you should multiply $60 by 5 to get $300 as the original cost and as your answer.
The number 90,000+600+8 in word form is Ninety thousand six hundred and eight.
<u>SOLUTION:
</u>
Shelly wrote the following number in expanded form. 90,000+600+8.
We have been asked to write the number in word form.
The number has been expanded into ten thousand, hundred and ten with additive mathematical operator in between.
So, the given number can be written as follows:
90,000 = ninety thousand.
600 = six hundred
8 = eight.
But if we add the numbers together, we have:
=90,000+600+8.
=90,608
So, on putting the number in word from we get:
Ninety thousand six hundred and eight
