negative 5 x less than or equals minus 10
-5x<=-10
divide by -5 (this will flip the inequality)
x>=2
Solution: x>=2
It is actually based of of calculation, this isint really a trick its just and advance calculation system thats why you add and divite certain number :)
hope this helps ❤️
Represent the dress price using d.
$23
Savings were 0.18d = $23. Dividing both sides by 0.18, we get d = -------
0.18
= $127.78.
Check: What is 18% of $127.78? 0.18($127.78) = $23.
Thus, the original price was $127.78, the savings $23, and the price paid $104.78.
y = 6 - 3x
x + y = 62
Since we already know the value of y, we can use substitution to find the value of x.
x + 6 - 3x = 62
<em><u>Subtract 6 from both sides.</u></em>
x - 3x = 56
<em><u>Combine like terms.</u></em>
-2x = 56
<em><u>Divide both sides by -2</u></em>
x = -28
Now that we know the value of x, we can solve for the value of y.
x + y = 62
-28 + y = 62
<em><u>Add 28 to both sides</u></em>
y = 90
The value of y is 90, and the value of x is -28 (this is your answer)
To make sure that these values are correct, we can plug them into the original equations.
y = 6 - 3x
x + y = 62
90 = 6 - 3(-28)
90 = 90 √ this is correct
-28 + 90 = 62
62 = 62 √ this is also correct
Answer:
They won 10 matches.
Step-by-step explanation:
The ratio is 2 wins to 3 losses.
You can use a proportion.
2 wins is to 3 losses as x wins is to 15 losses.
2/3 = x/15
3x = 2 * 15
3x = 30
x = 10
Answer: 10 wins
