The value of 5 is 10 because it is in the tens place. If you draw a place value chart it shows that 5 is in the tens place. You could also draw it with 5 blocks with ten cubes.
Happy studying ^_^

For the x-int, replace y with 0
for the y-int, replace x with 0
x-int:
12x-16(0)=-48
12x=-48
x=-4
y-int:
12(0)-16y=-48
-16y=-48
y=3

Left to right - Q1 - Q5
1,500, 1,250, 0.25, 105, 25%
Step-by-step explanation:
Q1 - 15,000 * 0.02 * 5 = 1,500
Q2 - 25,000 * 0.01 * 5 = 1,250
Q3 - 20 - ((6 * 1) + (3 * 0.75) + (10 * 0.35) + (4 * 2)) = 0.25, 25 cents
Q4 - 30x + 1,000 = 4,200 (X = 107) Approximately 105 jobs
Q5 - 1,584 / (32 * 66) = 0.75 (75%) 100% - 75% = 25%
Answer:
boys
Step-by-step explanation:
Let 
= total number of ninth graders. By knowing how many students there are in the grade, we can find for the number of boys.
(number of girls in ninth grade)
To find for the number of boys, we can use substitution:
∴ There are boys in the class.
Hope this helps :)
The first set:
3x + 2y = 2 ---1)
5x + 4y = 6 ---2)
From 1), multiply all by 2, 6x + 4y = 4 ---3)
3) - 2),
6x + 4y - (5x + 4y) = 6 - 4
6x + 4y - 5x - 4y = 2
x = 2
Sub in x = 2 into 1),
3(2) + 2y = 2
2y = -4
y = -2
(2 , -2)
The second set:
3x + 2y = 2 ---1)
11x + 8y = 10 ---2)
From 1), multiply all by 4, 12x + 8y = 8 ---3)
3) - 2),
12x + 8y - (11x + 8y) = 8 - 10
12x + 8y - 11x - 8y = -2
x = -2
From this x value alone, we can tell that these two linear systems do NOT have the same solution as they meet at different coordinates.
Hope this helped! Ask me if there's any working from here that you don't understand! :)
