Answer:
Step-by-step explanation:
3w + 2c = 32
4w + 3c = 44
Multiply the 1st equation by 4 and 2nd equation by 3, we get:
12w + 8 c = 128
12w + 9 c = 132
Subtracting the top equation from the bottom equation, we get: c = 4
Substituting c = 4 in any one of the above equations and solving, we get: w = 8
Therefore, weight of 2w + 1c = 2(8) + 4 = 20 pounds (Answer)
Answer:
Her weekly wage is $1150.
Step-by-step explanation:
It is given that,
Grace spent 16% of her weekly wage on a new bookshelf that cost $184.
We need to find her weekly wage.
Let her weekly wage is x.
ATQ,
![16\%\ of\ x=184\\\\x=\dfrac{184}{16\%}\\\\=\dfrac{184}{\dfrac{16}{100}}\\\\=\$1150](https://tex.z-dn.net/?f=16%5C%25%5C%20of%5C%20x%3D184%5C%5C%5C%5Cx%3D%5Cdfrac%7B184%7D%7B16%5C%25%7D%5C%5C%5C%5C%3D%5Cdfrac%7B184%7D%7B%5Cdfrac%7B16%7D%7B100%7D%7D%5C%5C%5C%5C%3D%5C%241150)
So, her weekly wage is $1150.
Answer:
no, because 90 kph would be 55.9234 mph so that would not be speeding.
Step-by-step explanation:
plz give me brainliest!
Complementary angles: angles whose measures add up to 90 degrees.
x+57=90
x=33 degrees
cosine(33) = 0.83867056794542
0.83867056794542 rounded to the nearest hundredth is 0.84
The correct answer is D) 0.84
