One number is 44 times a first number. a third number is 100 more than the first number. if the sum of the three numbers is 5385
svlad2 [7]

I take it that the actual total is 538. If it really is 538538 leave me a note.

Let the first number = x

Let the second # = 44x

Let the third # = 100x

Equation

x + 44x + 100x = 538 Add the left side. All terms are part of the total.

145x = 538 Div By 145

x = 538/145

x = 3.71

Check

First number = 3.71

Second # = 44*3.71 = 163.24

Third number = 100*3.71 = 371

Total these 3 numbers 537.95 The very tiny difference is due to rounding.

A pair of in-line skates is on sale for $90 iF this price represents 9% discount form the original price,what is the original pr
just olya [345]
Let x = original price in dollars

x is the original price
9% of this original price is equal to 0.09x

subtract: x - 0.09x = 0.91x

The discount price is equal to 0.91x and it's equal to 90 dollars, so they must be the same value. Ie.

0.91x = 90
0.91x/0.91 = 90/0.91
x = 98.9010989
x = 98.90

So the original price is $<span>98.90</span>

Let f(x) = x + 7 and g(x) = x − 4. Find f(x) ⋅ g(x). (1 point) x2 − 3x −28 x2 − 3x − 11 x2 + 3x − 28 x2 + 3x − 11
slavikrds [6]

f(x)=x+7\\g(x)=x-4\\f(x)*g(x)=(x+7)(x-4)\\f(x)*g(x)=x^2+3x-28

So it's x^2+3x-28
