Answer:
x=1.46875 or x=1.5
Step-by-step explanation:
1st step subtract 1.8 on both sides
-9.6x=-14.1
2nd step divide -9.6 on both sides
x=1.46875
or
x=1.5

What is the probability of rolling an even number on the first roll of a number cube and rolling an odd number on the second roll?
Answer:
1/4.
Step-by-step explanation:
There are 3 even numbers in the 6 numbers on a cube.
So Probability first roll is even = 3/6 = 1/2.
By the same reason Probability of odd number = 1/2.
So: Probability(First is even and second is odd) = 1/2 * 1/2 = 1/4.
Hi I need help with this hope someone has the answer.A triangular window is above the door to a café. The length of the base of the window is 12 feet, and the height is 10 feet
What is the area of the window?
Answer:
the answer is 60
Step-by-step explanation:
12×10=120
120÷2=60
Step-by-step explanation:
Sample Response: The height of the triangle will be twice the height of the rectangle. The area of a triangle is ½ bh and the area of a rectangle is bh. If the bases are the same, then the height of the triangle has to be double that of the rectangle in order to get the same area.
Select the correct answer. One factor of the polynomial 2x^3–3 x^2 - 3x + 2 is (x- 2), which expression represents the other factor, or factors, of the polynomial?
Answer:
D
Step-by-step explanation:
The factorisation of polynomial is (2x-1)(x+1). Therefore, option C is the correct answer.
The given expressions are 2x³-3x²-3x+2 and x-2.
What are factors of polynomial?The factors are the polynomials which are multiplied to produce the original polynomial.
Here, the given polynomial can be factored as follows:
x-2 |2x³-3x²-3x+2| 2x²+x-1
2x³-4x²
(-) (+)
___________
x²-3x+2
x²-2x
(-) (+)
___________
-x+2
-x+2
(-) (+)
____________
0
2x²+x-1 can be rewritten as 2x²+2x-x-1
= 2x(x+1)-(x+1)
= (x+1)(2x-1)
The factorisation of polynomial is (2x-1)(x+1). Therefore, option C is the correct answer.

two times the sum of a number and 18 is at least -21
Answer:
2x + 18 ≥ 21
x ≥ 2/3
Step-by-step explanation:
Let sum be X
2 times the sum means 2x
the sum of a number and 18 means x + 18
at least -21 means ≥ 21
put them together, and you get, 2x + 18 ≥ 21
If solving for x,
2x + 18 ≥ 21
2x ≥ 3
x ≥ 2/3

Be sure to include the correct unit in your answer.
Answer:
the answer is 12 yd if you are talking about the question mark.
Step-by-step explanation:
Well, if you split this figure into two rectangles, then the 16 yd length becomes 12 yd because the one congruent to it is 4 yd. Both sides are congruent so you'd get 12 yd.

A number cube is labeled 1 through 6. What is the probability of NOT
rolling a 2?
Answer:
Step-by-step explanation:
each of the 6 number has a 1/6 chance of being rolled
1 2 3 4 5 6
1/6 1/6 1/6 1/6 1/6 1/6
Every time the cube is rolled there is a 6/6 chance of any number comes up
1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 6/6 or 1
What is the probability of NOT rolling a 2? Any other number
1 2 3 4 5 6
1/6 + 0 + 1/6 + 1/6 + 1/6 + 1/6 = 5/6 or 0.8333

Choose Yes or No to tell whether the symbol will be reversed when the variable is isolated in each inequality. –10.5 < 3a b6 ≤ 7 –4.5c > 9 –215 ≤ –52d
Answer:
1). No, symbol won't be reversed
2.) No, symbol won't be reversed
3.) yes, symbol will be reversed
4.) No, symbol won't be reversed
Step-by-step explanation:
1.)
-10.5 < 3a
-10.5 /3 < 3a /3
-3.5 < 3 (No)
2.)
b/6 ≤ 7
Multiply both sides by 6
b/6 * 6 ≤ 7 * 6
b ≤ 42 (No)
3.)
-4.5c > 9
Dibide both sides by - 4.5
-4.5c / - 4.5 > 9/-4.5
c < 2 (yes)
4.)
–21/5 ≤ –5/2d
Multiply both sides by 2/5
-21/5 * 2/5 ≤ - 5/2d * 2/5
-21/2 ≤ - d
21/2 ≤ d (No)
