Sale price = $450
original price = 25%y
dicount = +20%
solution = $450 × 45%
= $202.5
= $652.5
i am a mathematics teacher. if anything to ask please pm me
Solve the second equation using the given choices:
Y = 3x + 6
Replacing x with the given choices and matching the y values the answer is the second choice
(0,6) and (-2,0)
Brother one: x
Brother two: x + 15
---
Make them add up to 55 in an equation.
x + (x + 15) = 55
Combine like terms.
2x + 15 = 55
Subtract 15 from both sides.
2x = 40
Divide both sides by 2.
x = 20
Plug 20 for x into brother two.
(20) + 15 = 35
Brother one has saved $20, brother two has saved $35.
10q - 30....factor out the common factor which is 10
10(q - 3) <===
Answer:
No, it doesn't.
Step-by-step explanation:
In order to find what makes a triangle, lets use the Triangle Inequality Theorem!
This theorem can help us show whether the sum of two side lengths of a triangle is greater than the third side or not
Here is our formula(s):
1.)<em> a + b > c</em>
2.)<em> a + c > b</em>
3.) <em>b + c > a.</em>
Lets make a=12, b=7, & c=5
1.) 12 + 7 > 5
19 > 5
2.) 12 + 5 > 7
17 > 7
3.) 7 + 5 > 12
10 > 12
As you can see, both numbers 1 and 2 shows to be correct but 3 is not. Therefore it doesn't make a triangle. Remember, if <em>all</em> the two side lengths of a triangle is greater than the third side, then it makes a triangle.
