Answer:
She sold 72 small photos and 54 large photos.
Step-by-step explanation:
We can set a equations system with the given information. Let X be the quantity of small photos and Z large photos.
We are told that she sold 126 photos in total, so:
X + Z = 126
Also, she earned 2,250 by selling certain quantities of small photo and large photos, so:
$2,250 = $11X + $27Z
From the first equation we get that X=126-Z, replace that into the 2nd equation:
2,250 = 11(126-Z) +27Z
2,250 = 1,386 - 11Z + 27Z
2,250 - 1,386 = 16Z
864 = 16Z
Z = 864/16
Z = 54 is the number of large photos sold. Now find X.
X = 126 - Z
X = 126 - 54
X = 72 is the number of small photos sold.
The equation which equivalent to given expression − 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) is
- x+15
- ( 12 x − 11 x ) + ( 18 − 3 )
The Correct option is (C) and (E)
<h3>What is Linear equation in one variable?</h3>
A linear equation is an equation of a straight line, written in one variable. The only power of the variable is 1. Linear equations in one variable may take the form ax+ b = 0.
The given equation is:− 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) .
= -3x+18 + 12 x -8x-3
=x +15
The corresponding equation to the above equation is:
C. x+15
D. (12 x - 11x) + (3-18)
= x-15
E. (12 x - 11x) + (18-3)
= x+15
F. (12 x - 11x) + (-6+3)
= x-3
As from the above it can be seen that the equation which equivalent to given expression − 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) . is
- x+15
- ( 12 x − 11 x ) + ( 18 − 3 )
