Answer:C n + 6(7)

Step-by-step explanation:

C n + 6(7) because, in order to find the cost of the t-shirts, you need to multiply 7 by n, which is the cost of one t-shirt. The cost of the tax would be 6 multiplied by 7 because the tax is $6.

Answer:

The answer is 16%

Step-by-step explanation:

use the percent error formula.

$\frac{|E-T|}{|T|} *100$

in this problem,

e= 75

t=90

substitute and solve.

$\frac{|75-90|}{|90|} *100\\\frac{|-15|}{|90|}*100\\\\ .16667*100\\$

16%

we are dealing with percents so rounding to nearest whole number will suffice.

hope this helps!

Answer:

TS=22

Step-by-step explanation: Since we know the triangles are proportional, we need to set up an proportion to find TS. First, let find which sides are correspond with each, TS and MN does and US and NQ does. So we set up a proportion that includes.

TS/US=MN/NQ: Let plug in the numbers

3x+1/26=5x-2/39: Then cross multiply

39(3x+1)=26(5x-2): Then simplify

117x+39=130x-52: Subtract 117x from both sides

39=13x-52: Add 52 to both sides

91=13x: Divide 13 by both sides

7=x: Then plug it in to TS

3(7)+1=22
