Please correct me if I’m wrong. Hope this helps!
In words:
Three sandwiches, each costing $5.25, equals 1/3 of Cassie's total money
We can write the formula:
(5.25*3)=1/3x
Now solve:
15.75=1/3x
3(15.75)=x
x=$47.25
Hope this helps!!
Answer:
Step-by-step explanation:
2y = -x +9
3x - 6y = -15
The solution is the value of x and y that will make the two equations true in the same time.
3x-6y = -15; divide both sides by 3
x-2y = -5; substitute 2y for -x+9 because the first equation tell us they are equal
x-(-x+9) = -5; open parenthesis
x+x-9 = -5 ; add 9 to both sides and combine like terms
2x = -5 +9; 2x = 4; divide both sides by 2
x= 2
Substitute x for 2
2y = -x+9 ; 2y = -2 +9 ; 2y = 7; y = 7/2 = 3.5
Solution is (2, 3.5)
Bill should put the brackets around 18-9 so the correct answer is option B. 10- 4 +3 x (18-9)
Answer:
y = 1.5x + 4
Step-by-step explanation:
Slope = (y2-y2)/(x2-x1)
= (1-4)/(-2-0) = -3/-2 = 3/2
y = (3/2)x + c
When x=0, y=4 (y-intercept is 4)
y = (3/2)x + 4
y = 1.5x + 4
