0.1(t+0.5) +0.2t =0.3(t-0.4) (answer)

0.1 (t + 0.5) + 0.2t = 0.3 (t - 0.4); 0.1t + 0.05 + 0.2t = 0.3t - 0.12; 0.3t + 0.05 = 0.3t - 0.12; 0.05 = 0.12 which is obviously not true. Hence there is no solution to this problem.

word problem ? (answer)

So when the problem is saying that 3 out of every 8 students prefer strawberry to vanilla, it means that 3/8 of all students like strawberry better. There are 160 students in total, so that means 3/8 * 160 or 60 students like strawberry.

0.1(w+0.5) +0.2w =0.2 (w-0.4) (answer)

0.1 (w + 0.5) + 0.2w = 0.2(w - 0.4); 0.1w + 0.05 + 0.2w = 0.2w - 0.08; 0.1w + 0.05 = -0.08; 0.1w = -0.13; w = -1.3

How do I solve inequality and graph them (answer)

Destiny, I'll assume that the "_>" in your question means "greater than or equal to" (it's usually written >= on a computer). 4 + 2 (-8p - 1) >= -94; -16p - 2 >= -98; -16p >= -96; p <= 6. (Remember, if you're dividing by a negative in an...

simplify (3-2i)/(1-i) (answer)

(3 - 2i) / (1 - i) = [(3 - 2i)(1 + i)] / (1 - i)( 1 + i) = (3 + 3i - 2i - 2i2) / (1 - i2) = (5 + i) / 2

How do I solve this equation: 5(x+3)-(4x-6)=-4 (answer)

Hello Janie. Since you didn't get the right answer by taking answers out of the bank, let's try a solution method that doesn't involve guess-and-check. 5 (x + 3) - (4x - 6) = -4; 5x + 15 - 4x + 6 = -4; x + 21 = -4; x = -25. So your not finding an answer is...

simplify each expression . show cancelling and factoring . (answer)

The basic idea is to divide both numerator and denominator by the factors that they share: 18/24 = (3 * 6) / (4 * 6) = 3/4. Here, 6 is the shared factor. 7rs3/21r2s = (7 * rs * s2) / (3 * 7 * rs * r) = s2 / 3r. Here, 7rs is the shared factor. 1/4 * 24x = 24x / 4 = 6x. Here, the shared...

Need help with this math question (answer)

See how the two points have the same x-value (-3)? That means it's a vertical line and comes in the form of x = something. Here, that something is -3. It's not possible to write vertical lines in slope-intercept form, so x = -3 would be the answer to your question.

Find the inverse Laplace transform? (answer)

I found an alternative answer. We can first factor (2s - 3)/(s2 - 4) into A/(s+2) + B(s - 2). By the solution methods in your book, you should get A = 7/4 and B = 1/4. We know that F(s) = A/(s - a) means that f(t) = e-at, so what you should get for the answer is f(t) = 7/4 * e-2t...

Help! Math word problem! (answer)

From the question we can tell that Dan drove for 3 hours. Castel left the mall one hour before Dan, so she drove for 4 hours. For convenience's sake, we say that Castel drives with a speed of x; in this case, Dan's speed is x - 40 (he drives 40mph more slowly). Now we can set up the equation:...
