Answer:

We are assuming the numbers 1 - 6 on the cubes?

If so,

Blue (3, 4, 5, or 6) is 4/6 or 2/3 chance

Green(1,3,5) is 3/6 or 1/2 chance

To get both the P is 2/3 times 1/2

Let a, b, c, and d be nonzero real numbers. If the quadratic equation ax (cx + d) = –b (cx + d) is solved for x, which of the fo
gayaneshka [121]

Answer:

x_1=-\frac{b}a,x_2=-\frac{d}c

Step-by-step explanation:

Solving for x:

ax(cx + d) =-b(cx +d)\\ax(cx + d)+b(cx+d)=0\\(ax+b)(cx+d)=0

In this form is easy to identify the factors of the quadratic function: (ax+b)(cx+d). The two solutions are the values ​​that make each of the factors equals to zero.

ax_1+b=0\\ax_1=-b\\x_1=-\frac{b}a\\cx_2+d=0\\cx_2=-d\\x_2=-\frac{d}c

Write 5.2 as the quotient of two integers <br> A...11/3<br> B...21/5<br> C...26/5<br> D...51/10
lidiya [134]
Since this problem involves division, we are going to do the opposite of it, which is multiplication. We are going to multiply the quotient by the denominator, the answer would be correct if the answer equals the numerator.
5.2*3=15.6
5.2*5=26
5.2*5=26
5.2*10=52

The answer would be C!

professor190 [17]
Set up a proportion:
\frac{64}{16.2} =  \frac{x}{18.5}

Cross multiply:
(64*18.5) = 16.2x

Simplify:
1184 = 16.2x

Solve for x:
x =  \frac{1184}{16.2}

Simplify:
x = 73.1

2(n-1)+4n=2(3n-1)
aleksandr82 [10.1K]

Answer:

Infinitely many solutions.

Step-by-step explanation:

2 (n - 1) + 4n = 2 (3n - 1) Let's simplify this to solve it.

2n - 2 + 4n = 6n - 2 Distribute 2(n-1) and 2(3n-1)

2n + 4n - 2 = 6n - 2 Rearrange the left side of the equation.

6n - 2 = 6n - 2 Add 2n + 4n.

-6n        -6n Subtract 6n from both sides.

-2 = -2? Yes, -2 equals -2.

Therefore, the answer is infinitely many solutions, meaning that <em>n </em>can be any real number.
