Answer:
3mph
Step-by-step explanation:
his speed per hour will be 3 miles per hour
X ^2 +6x+ 5
(x+2)(x+3)
2 + 3 = 5
While also 2•3= 6
The two numbers have to equal b when multiplied and c when added
Answer:
202
Step-by-step explanation:
200 + 0 make sure to add 2
201+ 1
202+ 2
Let x = number of pages holding 2 cards,
y = number of pages holding 3 cards.
So his total number of card would be 2x + 3y, which is given as 18. So we get this equation.
2x + 3y = 18
Subtract 3y from both sides:
2x = 18 – 3y
Divide both sides by 2:
x = (18 – 3y)/2
x must be an integer. So 18–3y must be a multiple of 2. Since 18 is a multiple of 2, 3y is also a multiple of 2. Then y must be a multiple of 2 too.
Let's start with y = 0.
When y = 0, x = (18 – 3(0))/2 = 9.
When y = 2, x = (18 – 3(2))/2 = 6.
When y = 4, x = (18 – 3(4))/2 = 3.
When y = 6, x = (18 – 3(6))/2 = 0.
Thus there are 4 ways to display his figures.
Answer:
r(t) = 75 kg - (4.5 kg/wk)w
Step-by-step explanation:
Let r(t) represent the amount of rice remaining after w weeks.
Then:
r(t) = 75 kg - (4.5 kg/wk)w
