Answer:

Step-by-step explanation:

x+y = 6

y = (6-x)

7x +12y = 52

7x+12(6-x) = 52

7x +72 -12x = 52

-5x = -20

x= 4 4 days at $7 = $28

2 days at $12 = $24

28+24 = 52

Factor the trinomal below below x^2 + 5x - 24

tamaranim1 [39]

Step-by-step explanation:

When I began factoring, I used the AC method (from the form Ax^2+Bx+C).

First, I multiplied the A and C terms, so you would multiply the 1 and -24 to get -24.

Now you need to find factors that multiply to get -24 and see if the sum of any of the pairs gets B, the middle term, 5.

These factor pairs include: 1, -24; 2, -12; 3, -8; 4, -6; 6, -4; 8, -3; 12, -2; 24, -1.

The sums of the pairs are as follows: -23, -10, -5, -2, 2, 5, 10, 23.

Since the 8, -3 pair multiplies to get -24, and adds up to 5, your factors are (x+8)(x-3).

Just to be safe multiply it out to check your work.

How to convert decimals into fractions in simplest form

madam [21]

For example, lets take $\frac{25}{100}$

We need to first factor the numerator and denominator to find the common numbers which we can simplify it by.

$\frac{25}{100} = \frac{5 \times 5}{5\times 5\times 4}$

If we divide by 5 x 5 on both the numerator and denominator because both of them have it in common, we will get the simplest form.

$\frac{5 \times 5\div 5 \div 5}{5\times 5\times 4\div 5\div 5} = \frac{1}{4}$

Arc is 41 and angle is 40. I have no other given information but I have to find x

tiny-mole [99]

First of all I want to point out you drew the diagram a little wrong. The Arc is 41 doesn't mean its 41 degrees it means it has length 41 so remove the degrees symbol.

Now for the answer the other arc have to have angle 40 too because vertical angles. And because the radius is the same, both of the length has formula 40/360*pi*2*radius which is 41 in this case. So x has to be 41 also :) Done!
