The equation should be 105(0.15)+ x = 170 and the value of x is 154.25
Important information:Mr. Muñoz has a coupon for 15% off his entire purchase. He buys binoculars for $105 and hiking boots. He spends a total of $170 before tax.Equation and calculation:Here we assume the hiking boots cost be x
So, the equation is
105(0.15) + x = 170
15.75 + x = 170
x = 170 - 15.75
x = 154.25

Solve for xxx. -30=5(x+1)
First, apply the distributive property:
-30 = 5(x + 1)
-30 = 5x + 5
Substract 5 from both sides:
-30 - 5 = 5x + 5 - 5
-35 = 5x
Divide both sides by 5:
[tex]\mathsf{\dfrac{-35}{5} = \dfrac{5x}{5}}[/tex]
[tex]\large{\boxed{\mathsf{-7 = x}}}[/tex]
Let's check the answer:
-30 = 5(x + 1)
-30 = 5(-7 + 1)
-30 = 5(-6)
-30 = -30
The answer is correct.
Answer. The value of x = -7.If you bought a stock last year for a price of 103$ and it has risen 13.5% since then, how much is the stock worth now, to the nearest cent?
Answer:
$90.75
Step-by-step explanation:
103*100=(13.5%+100%)*x
10300=113.5x
x=10300/113.5
x=90.74889868
x=$90.75
3х + Зу = -x+5y ordered pair
Answer:
2x-y=0
x=1/2y
Step-by-step explanation:
Answer:
Your solution is (1/2, 1).
Step-by-step explanation:
3х + Зу = -x + 5y
First we want to look at each side of the equation separately.
3х + Зу ⇒ This expression is fully simplified because you cannot add different variables together.
-x + 5y ⇒ This expression is fully simplified because you cannot add different variables together.
3х + Зу = -x + 5y
Now, let's bring the like terms together.
[add x to both sides]
x + 3x + 3y = -x + x + 5y
4x + 3y = 5y
[subtract 3y from both sides]
4x + 3y - 3y = 5y - 3y
4x = 2y
We want to solve for one variable at a time, so let's isolate x.
[divide both sides by 4]
4x/4 = 2y/4
x = 1/2y
Now we have an expression for x. Plug this expression in to your original equation.
3х + Зу = -x + 5y
3(1/2y) + 3y = -(1/2y) + 5y
According to PEMDAS (parentheses/exponents | multiplication/division | addition/subtraction), we should multiply first.
3(1/2y) + 3y = -(1/2y) + 5y
3/2y + 3y = -1/2y + 5y
Now let's add on each side.
9/2y = 9/2
Now we need to isolate y by dividing both sides by 9/2 (or multiplying by its reciprocal 2/9 ← This is often easier to understand when written)
[tex]\frac{2}{9} (\frac{9}{2} y) = \frac{9}{2} (\frac{2}{9} )[/tex]
In this form, we can see that the fractions cancel each other out.
y = 1
Now that we have the value of y, plug it into our equation for x.
x = 1/2y
x = 1/2(1)
Multiply.
x = 1/2
Your solution is (1/2, 1).
You're almost done! Check your answer by plugging in both these values in to your original equation.
3х + Зу = -x + 5y
3(1/2) + 3(1) = -(1/2) + 5(1)
Multiply.
3(1/2) + 3(1) = -(1/2) + 5(1)
3/2 + 3 = -1/2 + 5
Add.
9/2 = 9/2
This equation is true, therefore your answer is correct!
