$1.60.
You do 100 divided by 625 to get 16 cents. You then multiply .16 times 10 to get $1.60
Answer:
x = 1
y = -1
Point = (1,-1)
Step-by-step explanation:
2x + 3y = -1 = y = -2/3 - 1/3
5x + 2(-2/3 - 1/3) = 3
5x - 1 1/3 - 2/3 = 3
5x - 2 = 3
<u> +2 +2</u>
5x = 5
<em><u>x = 1</u></em>
2(1) + 3y = -1
2 + 3y = -1
<u>-2 -2</u>
3y = -3
<em><u>y = -1</u></em>
Answer:
Step-by-step explanation:Simplifying
2a + 6b = 100
Solving
2a + 6b = 100
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-6b' to each side of the equation.
2a + 6b + -6b = 100 + -6b
Combine like terms: 6b + -6b = 0
2a + 0 = 100 + -6b
2a = 100 + -6b
Divide each side by '2'.
a = 50 + -3b
Simplifying
a = 50 + -3b
Answer:
(x, y)=(4,-8)
Step-by-step explanation:
9x+y=28
3x+3y=-12 /:(-3)
9x+y=28.......(1)
-x-y=4......(2)
9x+y=28
(1)+(2): 8x=32
9x+y=28
x=32/8
9x+y=28
x=4
9*4+y=28
x=4
36+y=28
x=4
y=28-36
x=4
y=-8
x=4
(x, y) =(4,-8)
Answer:
First you have to know what x and y mean in the equation. They told you in the problem that x is the avg # of feet the tree grew each month. That means that the number multiplied by x is the number of months.Y will be the total height. That number is 57.6. When y = 57.6, the number that should be multiplied by x is 16.The tree starts at 8 ft tall, not 0 feet, so the y-intercept in this equation should be 8, because even when 0 months have passed, it will be 8 ft tall. So you know the equation will have the +8 in it added to the slope times x part.It should be d. 16x + 8 = 57.6.
