Answer
(-3 * 2p) - (-3 * 3q)
Step-by-step explanation:
I dunno how to explain it but that's it
Divide 600,000 by 10,000.
Equals 60!
Answer is 60.
Answer:
wer: The true statement is 'Line TU is parallel to line RS'. Explanation: Since, we know that if a line is perpendicular to two different lines then these two different lines must be parallel to each other. Here, it is given that WV is perpendicular to both lines RS and TU. Therefore, RS must be parallel to TU.
Let s be the cost of one shirt and t, the cost of 1 tie
Then:
(a) 3.s + 5.t = 60
(b) 2.s + 3.t = 39
Solve this equation by elimination:
<span> Let's eliminate t. To that end you multiply all the terms of (a) by negative 3 and all the terms of (b) by positive 5
</span>(a) 3.s + 5.t = 60→→ (-3).(3.s+5.t) → - 9.s - 15.t = -180(c)
(b) 2.s + 3.t = 39→→ (+5).(2.s+3.t) → +10.s + 15.t = 195 (d)
Now you add (c) + (d) → s= $15 , This is the cost of 1 shirt. To find the cost of 1 tie, you replace s by 5 in any of the equation, say (b):
(b) <span>2.s + 3.t = 39 </span>→ 2.(15) + 3t = 39 → 30+3t = 39 and 3t =39-30 = 9
So 3t = 9 and t = $3 (price of 1 tie)
