yes because you would subtract -9 from both sides of the equation leaving you with x = -4
Answer:
x ≈ 11.1
Step-by-step explanation:
Using the cosine ratio in the right triangle.
cos42° = = ( multiply both sides by 15 )
15 × cos42° = x, then
x ≈ 11.1 ( to the nearest tenth )
Answer:
x= -2 and y= 3
Step-by-step explanation:
since x = 2y -8, substitute this in the first equation
Thus, -3(2y-8) + 2y =12
-6y+24+2y=12
-6y+2y=12-24
-4y=-12
y=3
put the value of y in the second equation,
x=2y-8
x=2(3)-8
x=6-8
x=-2
So, x=-2. y=3
a= -5 , -2
b= 1 , 0
not sure if that helped sorry if i didnt
To find the price of something with sales tax, you simply multiply it by 1.(percent as a decimal). The "1" represents the original price, while the decimal afterwards represents the percent of sales tax. In this case, 3% is .03 as a decimal, so we should be multiplying 55 by 1.03.
55
<u>x1.03
</u>56.65
<u>
</u>Using the math above, we can see that the price of the shoes with the sales tax is $56.65.<u>
