You want to solve this set of linear equations by the elimination method.
Let x=price of bag of flour and y=price of bag of sugar
Multiply the first equation by -3.
-3(7x+5y=584)
Multiply the second equation by 5.
5(5x+3y=384)
Solve by elimination.
X=42
Substitute value of x into one of the original equations.
Y=58
Answer: 57.6m
Step-by-step explanation:
That's a lot of words that questions usually use to try to trip us up but not this time so lets pull all relevant information
199.2m= top of off shore oil rig
-9.6 m is the base of the rig
observation deck is 1/6 of the total height
helly pad is 22.8m above the observation deck
First lets try to find the total height of the rig. We can do this by adding the absolute value of the top and base of the oil rig. So 199.2 + 9.6 = 208.8m
So the total height is 208.8m now lets find the observation deck. We know the observaition is 1/6 of the total height which is 208.8m right so lets multiply. 1/6*208.8m= 34.8m
Now we know the observation deck is 34.8m high. Finally we can find the helly pad which is 22.8 m above the observation deck.
Since the observation deck is 34.8m and the helly pad is 22.8 above observation deck (34.8m) all we have to do is add so 22.8+34.8= 57.6m
So we know the total height is 208.8m
The observation deck is 34.8m
And the helly pad is 57.6m
Answer:
63 Lights
Step-by-step explanation:
First you can convert the feet to inches:
The length of decorative lights is 264 inches
You can then subtract 16 from 264
264 - 16 = 248
248/4 = 62
Adding one extra light at the end of the string of decorative lights you can get 63 lights on the string
Answer:
Mr. Nelson paid $48 befor tax.
Step-by-step explanation:
Let x be the price of the item before tax.
108 % * x - x = 3.84 (the tax itself)
27/25x - x = 3.84
2/25 x = 3.84
x = 48
The correct answer is B) $50 per hour. Hope this helps!
