Answer:
x = 3
y = 8
Step-by-step explanation:
Since it gives you x, you need to plug in the number given for it into the equation:
y = 3x - 1
y = 3(3) - 1
y = 9 - 1
y = 8
So now you have, x = 3 and y = 8
You'd simply have to find 20% of $40. To find the percent of a number, you would change the percent into an actual decimal/number, and then multiply them both. So the percent would become 0.20.
40 × 0.20 = 8
So now you would subtract 8 from the cost of 40.
40 - 8 = 32.
The shirt costs $32.
Answer:
Step-by-step explanation:
If angles C and B have equal degrees then the side AC is also equal to side AB in length and you can make their equations equal as well and solve for X.
2x+16=7x+6
get X's all on same side and the constants all on the other side,
-2x +2x+16=7x+6+-2x
The X's on the left cancel out.
16=5x+6
-6+16=5x+6+-6
add -6 to each side. On the right the 6 is now cancelled out.
10=5X
divide each side by 5 to cancel out the 5
10/5= 5X/5
2=X . ANSWER
