Question a is = 1/9 one over nine
b= 4 over nine I think
The two equations are: 3x + 2y = 36.50 (I)2x + 5y = 50 (II)Eliminating x from the two equations by subtraction:first we multiply equation I by 2 and equation II by 36x + 4y = 736x + 15y = 150Subtracting the two,-11y = -77y = 7He earns $7 at the coffee cartSubstituting y into equation I,3x + 14 = 36.5x = $7.50Therefore, he earns a greater wage of $7.50 at the library, the answer is C
Answer:
$6
Step-by-step explanation:
Set up an equation:
88 = 8x + 6x + 4
Where x is the price of the shirts and pants
Subtract 4 on both sides:
88 = 8x + 6x + 4
-4 -4
84 = 8x + 6x
Combine Like Terms:
84 = 8x + 6x
84 = 14x
Divide by 14 on both sides:
84 = 14x
/14 /14
6 = x
Therefore, the price of each shirrt or pair of pants is $6.
Answer:
Step-by-step explanation:
We can use the points (9, -3) and (-4, 1) to solve.
Slope formula: y2-y1/x2-x1
= 1-(-3)/-4-9
= 4/-13
= -4/13 (Option C)
