Answer:
17.41 Dollars
Step-by-step explanation:
First, you take the discount, which is 2 dollars, so now the cost without any additional costs is 22 dollars. Next, find 8 percent of 22 by multipling 22*0.08 and then you get 1.76. Subtract that from 22 and 20.24. Then take 14 percent of 20.24 by multiplying it by 0.14, which you get 2.8336. Round that down and you get 2.83. Subtract that from that and you get 17.41.
Answer:
10). 5x + (7x + 6) = 90
11). x = 7
Step-by-step explanation:
From the picture attached,
Sum of given angles measures 90°
Measures of the angles are (5x)° and (7x + 6)°
Therefore, equation to determine the values of x will be,
5x + (7x + 6) = 90
By combining similar terms of the equation,
12x + 6 = 90
12x = 90 - 6
12x = 84
x =
x = 7
Therefore, by solving the equation value of x will be 7.
Okay so let's first try to get the first equation in the same form as the second with y on one side.
We have 7x-y=10 so we will subtract 7x from both sides and we now have :
-y=-7x+10
Now we can add both equations!
-y=-7x+10
+ y=-7x+2
We end up with 0=-14x+12
subtract 12 from both sides and we have -12=-14x
divide by -14 and we have 12/14=x we can simply that fraction to 6/7.
Now that we know x=6/7, we can plug it into the equations to find y!
7(6/7)-y=10
7(6/7)=6 so we now have 6-y=10
Subtract 6 and we now have -y=4. We want to also divide the negative sign since there's also an invisible one attached to it so the answer is y=-4
Let's plug in 6/7 into the second one to see if we get -4 too!
y=-7(6/7)+2
y=-6+2
y=-4
So there we have it! x=6/7 and y= -4! Sorry i took so long!
