x + 20 = 90
x = 90 - 20
= 70
2. x + 36 = 90
x = 90-36

what is the answer to this inequality question 2(4x+1)<3(2x-3)
Answer:
x < -7
Step-by-step explanation:
2(4x + 1) < 3(2x - 3)
Distributive Property:
8x + 8 < 6x - 6
Subtract on Both Sides:
8x + 8 < 6x - 6

A container contains 3 yellow, 2 orange, and 4 pink roses. Without looking, if James chooses a rose from the container, what is the probability that James will select an orange rose?
Answer:
Orange rose = 2/9
Step-by-step explanation:
In order to find probability of picking one item, you add all the possible things you could choose. So, 3+2+4 equals a total of 9 outcomes, and that would be your denominator for your fraction of probability. From there it's really easy. Just put the amount of things your trying to find the probability for in the numerator spot.
Ex.
There are 9 total roses so that would be the denominator (?/9)
To find out the probability for picking an orange rose, you'd put the 2 in as the numerator because that is the total number of orange roses you have (2/?)
Then just put the two together (2/9).
Which of the equations are true identities? A. N ( n − 2 ) ( n + 2 ) = n 3 − 4 n B. ( x + 1 ) 2 − 2 x + y 2 = x 2 + y 2 + 1
Answer:
Both A and B are true identities
Step-by-step explanation:
A. N ( n − 2 ) ( n + 2 ) = n 3 − 4 n
We need to show that (left-hand-side)L.H.S = R.H.S (right-hand-side)
So,
n ( n − 2 ) ( n + 2 ) = n(n² - 2²) (difference of two squares)
= n³ - 2²n (expanding the brackets)
= n³ - 4n (simplifying)
So, L.H.S = R.H.S
B. ( x + 1 )² − 2x + y² = x² + y² + 1
We need to show that (left-hand-side)L.H.S = R.H.S (right-hand-side)
So,
( x + 1 )² − 2x + y² = x² + 2x + 1 - 2x + y² (expanding the brackets)
= x² + 2x - 2x + 1 + y² (collecting like terms)
= x² + 1 + y²
= x² + y² + 1 (re-arranging)
So, L.H.S = R.H.S
So, both A and B are true identities since we have been able to show that L.H.S = R.H.S in both situations.

The middle number is -9 and the last number is 8.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -9
Multiply together to get 8
Can you think of the two numbers?
Try -1 and -8:
-1+-8 = -9
-1*-8 = 8
Fill in the blanks in
(x+_)(x+_)
with -1 and -8 to get...
(x-1)(x-8)
15. Let's solve your equation step-by-step.
(x−2)(x−3)=2
Step 1: Simplify both sides of the equation.
x2−5x+6=2
Step 2: Subtract 2 from both sides.
x2−5x+6−2=2−2
x2−5x+4=0
Step 3: Factor left side of equation.
(x−1)(x−4)=0
Step 4: Set factors equal to 0.
x−1=0 or x−4=0
x=1 or x=4

Estimate the percent using decimals.
48% of 400
Step-by-step explanation:
getcalc.com's fraction to decimal calculator to find what's an equivalent decimal for the fractional number 48/400.
50/400 0.125 12.5%
49/400 0.1225 12.25%
48/400 0.12 12%
47/400 0.1175 11.75%
Answer:
fraction to decimal calculator to find what's an equivalent decimal for the fractional number 48/400.
0.12 is a decimal and 12/100 or 12% is the percentage for 48/400.
Step-by-step explanation:
A fraction consists of two numbers and a fraction bar:
48/400
The number above the bar is the numerator: 48
The number below the bar is the denominator: 400
Divide the numerator by the denominator to get fraction's value:
Val = 48 ÷ 400
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% = p/100 = p ÷ 100.
Calculate fraction's value.
Divide the numerator by the denominator to get fraction's value:
48/400 =
48 ÷ 400 =
0.12
Note:
100/100 = 100 ÷ 100 = 100% = 1
Multiply a number by the fraction 100/100,
... and its value doesn't change.
Calculate the percent value:
0.12 =
0.12 × 100/100 =
(0.12 × 100)/100 =
12/100 =
12%;

Answer:
10^3, 0.001
Step-by-step explanation:
Given:
1/(10×10×10)
Find:
The equivalent representations among the options ...
10^-3, 0.01, 0.001, 10^3
Solution:
The denominator is 10×10×10 = 1000, so the fraction is 1/1000.
The decimal representation of that is 0.001. In exponential form, it is ...
1/10^3 = 10^-3
Equivalents among the offered choices are 10^-3 and 0.001.

Suppose that baby grand piano cost $8000 and looses 15%
in value each year. What would be the value of the piano in
12 years? Round your answer to the nearest hundred.
A.) $1137.93
B.) $1274.88
C.) $1078.44
D.) $5780.00
Answer:
A
Step-by-step explanation:
If it loses 15% of its value every year, then each subsequent year will be worth 85% of the previous year. If we think of this as a geometric series, then the worth would be 8000(.85^t) where t is years after the first year. If you plug in 12, then it's 1137.93.
Answer:
1137.93 is the answer
