Hello :
<span>X - y = 4...(1)
x + y = 8...(2)
(1)+(2) :2x= 12
</span><span>The x-coordinate of the solution to the system shown is __6___.</span>
Answer:
y=60° b=60°
Step-by-step explanation:
the sum of all degrees of interior triangle is 180
in the first one, 30° and 90° have been given.(that small square represent 90°)
so 180°-90°-30°=60°
in the second one, the 120° is on the other side of a line, a line has a degree of 180, therefore the interior angle is 60°, the same rule 180°-2*60°=60°
Given:
Jason buys three shirts with a listed price of $20 each.
He uses a coupon that provides "Buy Two, Get One Free".
To find:
The total final price Jason pays.
Solution:
Total number of shirts he buys = 3
Since he uses a coupon that provides "Buy Two, Get One Free", therefore he need to pay for 2 shirts and 1 he will get free.
Cost of 1 shirt = $20
Cost of 2 shirts = 2 × $20
= $40
Therefore, total final price Jason pays is $40.
