Answer:
$3.61
Step-by-step explanation:
let p represent pizza and d represent drink, then
8p + 6d = 39.5 → (1)
5p + 7d = 30.44 → (2)
Multiplying (1) by 7 and (2) by - 6 and adding will eliminate d
56p + 42d = 276.5 → (3)
- 30p - 42d = - 182.64 → (4)
Add (3) and (4) term by term
(56p - 30p) + (42d- 42d) = (276.5 - 182.64), that is
26p = 93.86 ( divide both sides by 26 )
p = 3.61
That is a slice of pizza costs $3.61
Answer:
79.605

sin 31° = 41/x
x = 41/sin 31°
x = 79.605
Just relax, breathe deeply from the diaphragm, allow the
cleansing air to fill your brain, and take it one step at a time.
You said that <u>3t - 7 = 5t
</u>OK. Fine.
Let's just find out what <em>6t</em> is.
Subtract 3t from each side: -7 = 2t
Multiply each side by 3 : <em>-21 = 6t
</em>Did I go too fast for you ?<em>
</em>
The answer is 60. The formula is v=bxhxh/b or in this case 6x4x15/6. After you multiply the numerator you will get 360 and then you divide by 6 to get your answer: 60.
