5x + 15(170 - x) = 1600   Solve for x.   Then solve 170 - x.   Those are your 2 rates.

Try taking a photo of the figure and the problem and posting a link to it. Geometry is difficult without a reference. Also angles use 3 points to describe them, AD would be a line or line segment.

SOHCAHTOA   You are given the opposite and the adjacent so you would use tangent.   Tan = Opp / Adj = 6/8 = .75   So the angle is the inverse tangent of .75 or tan-1(.75) = 36.9   All angles in any triangle add up to 180 degrees, of which...

transitional epithelium is almost exclusively found in the bladder, ureters and urethra   dense irregular connective tissue is found in the dermis   areolar connective tissue is found in the hypodermis   loose connective tissue is a category of tissue that...

# of democrats = x   # of republicans = 2/3x + 7    x + 2/3x + 7 = 317   -7               -7   5/3x = 310     * 3/5    *3/5   x...

You factor by grouping.   (ab + 3b) + (2a +6)   Then you take out like terms, you need to make sure the terms left in the () are the same.   b(a + 3) + 2(a + 3)   This can now be written as:   (b + 2)(a...

You need a couple things to answer this question.   First you need the formula for gallons to liters conversion.   This is L = G / 0.26417   So 1G is equivalent to 3.7854L   Now you multiply that by the cost per L in Euros:   1.35(3...

No, you are multiplying two binomials.   It would be (x+5)(x+5) and you would have to FOIL it, First Outer Inner Last or:     x2 + 5x + 5x + 25 = x2 + 10x + 25   This is actually making it more complex not less.

Let VP = Present Value (x)   Let VI = Initial Value (11,000)   Let r = Rate (.10)   Let I = VI + rVI      Then VP = I + rI   Let's get I first:   11,000 + .10(11,000) = 11,000 + 1,100   I...

The definition of a function is that every x value may have one and only one corresponding y value.   Graphically we can test this by something called the VLT or vertical line test. If an equation is a function you must be able to draw a vertical line through it at any x value within...

There is not enough information here to solve this.   I'm guessing you have a figure to go off of with some known values.   Formula of a parallelogram's perimeter is P = 2L + 2W

P = 2L + 2W   Substituting known   W + 14.4 = 2(2W - 0.3) + 2W   -W                                ...

You need to remember one thing with inequalities. When you multiply or divide by a negative number you need to flip the inequality sign. Otherwise you solve it just as if it were a normal equation.   So number 4 for instance:   x/-10 > 6   * -10     ...

You were one when it was founded. The school was roughly 13 years old when you began attending.

They have different start points 17J vs 0H so you need to add/subtract 17   They raise at different rates 80 vs 120 so you will need to multiply     J = (H * 2/3) + 17   H = (J - 17)(3/2)   The fractions were achieved by reducing the...

Ok, first set the equations equal to each other.     500t3/2 = 100t2   Then isolate the t terms.   500t3/2 / 100 = t2   5t3/2 = t2   t2 / t3/2 = 5   Now remember that division of exponents with same base are subtracted...
