Answer:
I think it is 36 inches times 80
Some of the problems are in scientific notation, which if you don't know how to do, I will try to explain, when you see for example 1 x 10^3, what it is saying is basically 1 x 10 x 10 x 10 so in that case 1,000, simple trick is to look at what ever number is in the top right, then add that many zeroes. So this is most likely supposed to be a division problem. if you need more help message me.
X = the number of humans and y = the number of horses.
x+y=74
2x+4y=196
Because the number of humans and horses together is 74, and the total number of legs (2 per every human, x, and 4 per every horse, y) is 196. Then, just use elimination to solve.
So, now that you have y, you can plug it into the first equation to find x:
So, x = 50 and y = 24, so there are 50 humans and 24 horses.
The correct answer is B.
Answer:
Yes, the expressions are equivalent.
Step-by-step explanation:
Notice that -2 is defined as in additive inverse of 2, that is, 2 + -2 = 0.
and substracting 2 from 2 is also equal to zero, that is, 2 - 2 = 0.
Thus 2-2 = 2+ -2, implying -2 = + -2. Consequently, -5 + -2 = -5 -2
1/2=6, 6÷1/2=12, 1=12 because if 1/2×12=6, then 1×12=12
