Lets put the 36 into 8ths because 8ths are the smallest "unit." 1 = 8/8 so if we do 36*8, we get 288. Put the 288 over the 8 to make 288/8. Now lets do the same for the 7 and 1/2 and 9 and 1/8. 7*8= 56/8. Now take the 1/2 and multiply the denominator and the numerator by 4. you get 56/8 and 4/8. Add them together. You get 60/8. Now lets do 9 and 1/8. 9*8 is 72. Put the 72 on top, 72/8. Add the 1/8 to the 72/8. You get 73/8. You now have 3 numbers. 288/8, 60/8, and 73/8. Lets arrange them the way the problem wants us to. 288/8 - 60/8 - 73/8 = X. Subtract. You get 155/8. Now how many times does 155 go into 8? About 19 times. Now lets figure out the fraction. We have 3 leftover, so 3/8. The answer is 19 and 3/8. Hope I helped and taught ya something :)

How do you solve it?

MatroZZZ [7]

Answer:

i: x=-2, x=1

ii: x=-1/2

Step-by-step explanation:

Quadratic form:

You solve i by using FOIL (First, Outside, Inside, Last) because it is a multiplication problem.

$(x+2)(x-1)=0$

"first" would be $x*x$ , which would equal $x^{2}$

"outside" would be $x*-1$ , which would equal $-1x, or -x$

"inside" would be $2*x$ , which would equal $2x$

"last" would be $2*-1$ , which would equal $-2$

Now you need to combine the terms so that they are one after the other

$x^{2}-x$ $+2x-2$

Combine like terms, and you should get:

$x^{2} +x-2$

i Solution

You need to get the variable by itself.

Subtract two from both sides

$x+2=0\\x=-2$

Add one to both sides.

$x-1=0\\x=1$

ii Solution

Add all the terms.

$x+2+x-1=0\\2x+1=0\\2x=-1\\x=-\frac{1}{2}$

If AB = 12, AC = 16, and ED = 5, find AE.

AleksAgata [21]

Answer:

AE =15

Step-by-step explanation:

BC=16-12 = 4

AE=x

12/4 = x/5

Cross multiplication

4x=60

x=15

4x3 = 12

5x3 =15

True Or False?

natali 33 [55]

Electromagnets are devices that create a magnetic field through the application of electricity. Strong electromagnets are used to lift, move and drop heavy objects, such as vehicles. Electromagnets have advantages over permanent magnets. When the current is switched off, the electromagnet will lose its magnetism. The car will fall back to earth and we need that when we move cars in a junkyard. With a regular ( permanent ) magnet it would be much harder to do.
Answer: A. True
