1: 0.625, 2: 1.05, 3: 2 13/20
Step-by-step explanation:
Use a calculator to determine the exact value of the fractions, or do it by hand.
Answer:
0.625 , 1.05, 2 13/20
Step-by-step explanation:
Well, this isn't that hard if you really think about it.
For Number 1: 5/8 as a decimal, first you want to divide
100 by 8, which equals to 12.5. Then multiply 12.5 by 5 which gets you 62.5
Move the decimal place 2 to the left, and you get 0.0625.
For Number 2: 1 and 1/20
100/20=5
So you have 1 and 5/100, convert 5 to percent so 5%
5%+100%=105%
105= 1.05
Number 3: 2.65
100/20=5
13x5=65
0.65+2= 2.65, 2 13/20.

Which expression is a quadratic binomial?
A.) x^2 - 16x
B.) 12x^4 + 3x^2 - 6x - 1
C.) 9x^2
D.) 6x^4 - 12x
Answers
Answer:
A
Step-by-step explanation:
A quadratic is 'involving the second and no higher power of an unknown quantity or variable.'
Therefore, we can exclude b and d easily because both have a higher power of 2. 9x^(2) is not a binomial because it only has 1 term (i think its called a term) leaving A, x^2-16x as the only answer left.

Tony and Ricky spend a certain amount of money from their accounts each week at a pet shelter.
The table shows the relationship between the amount of money (y) remaining in Tony's account and the number of weeks (x):
Function 1:
Number of Weeks
(x) Amount Remaining (dollars)
(y)
1 30
2 24
3 18
4 12
The equation shows the relationship between the amount of money, y, remaining in Ricky's account and the number of weeks, x:
Function 2:
y = –7x + 30
Which statement states and explains which function shows a greater rate of change?
Function 1, because Tony spends $6 each week and Ricky spends –$7 each week
Function 2, because Ricky spends $7 each week and Tony spends $6 each week
Function 1, because Tony spends $18 each week and Ricky spends $23 each week
Function 2, because Ricky spends $30 each week and Tony spends $18 each week
Answers
Answer:
Function 2, because Ricky spends $7 each week and Tony spends $6 each week
Step-by-step explanation:
You find the rate of weekly rate of change by calculating the difference of the amount changing each week:
24 - 30 = - 6
18 - 24 = - 6
12 - 18 = - 6
As you see the rate of change is constant: - 6 dollars per week. This means that Tony is spending 6 dollars every week
Function 2: y = –7x + 30
The rate of change is the slope (m) of the linear function, and this is the coefficient of the independent variable, x.
This equation is written in slope intercept form (y= mx+b)
Then the rate of change is - 7 dollar per week. This means Ricky spends 7 dollars every week.
Now you know that the two rates are constant and that the second function shows a steeper decreasing.

width = 15 inches
length = 30 inches
Step-by-step explanation:
Let width = w
Length =2w
Perimeter = 90 inches
2*(length + width) = 90
2*(2w +w ) = 90
2* 3w = 90
6w = 90
w = 90/6
w = 15 units
length = 2*15 = 30 units

The answer is 100.
Step-by-step explanation:
I started with solving 4 divided by 5. It was 0.8. I then started going thru 1 to 10 to 20 to 50 to 100. I was comparing big numbers. I then realized 100+0.8 times 100 = 180!
Answer: [tex]x=100[/tex]
If the equation is [tex]x+\frac45 x = 180[/tex] we add on the LHS: [tex]x(1+\frac45) = 180 \rightarrow x(\frac55+\frac45)= 180\\\frac95 x = 180[/tex]
At this point we divide both sides by 9 and multiply by 5:
[tex]x=\frac 59 (180) = \frac59 (2\times 9 \times 10) = 100[/tex]

(•‿•)
Answers
Step-by-step explanation:
remember, we need to get to an expression of the form
y = ax + b
1.
x + 5y = 5
5y = -x + 5
y = (-1/5)x + 1
2.
3x + 2y = 4
2y = -3x + 4
y = (-3/2)x + 2
3.
2x + y = 4
y = -2x + 4
4.
4x - 2y = 6
2y = 4x - 6
y = 2x - 3
5.
8x - 4y = 16
4y = 8x - 16
y = 2x - 4
6.
3x + 4y = 4
4y = -3x + 4
y = (-3/4)x + 1
7.
9x - 4y = -16
4y = 9x + 16
y = (9/4)x + 4
8.
2x - 5y = 10
5y = 2x - 10
y = (2/5)x - 2
9.
3x + 5y = 10
5y = -3x + 10
y = (-3/5)x + 2
10.
7x - y = 4
y = 7x - 4
