I'll teach you how to do them, but not do them all for you.

2.
6:5 = ___:35
35 / 5 = 7
So you've got to multiply 6 by 7.
6:5 = 42:35

3. 
2:3 = 20:___
20 / 2 = 10
So you've got to multiply 3 by 10
2:3=20:30

4. 
36:24 = 6:___
36 / 6 = 6
So you've got to divide 24 by 6.
36:24 = 6:4

Keep trying and if you need more help feel free to ask.

In what ways does algebra act as a tool to improve communication? How does algebra affect how people can learn from each other?
Andreyy89

Answer: Algebra acts as a tool to improve communication because much like learning a new language, you have to take baby steps before you can fully get it. This can improve communication because you're learning something new with the help of others.

Hi! I've tried this problem a couple times but am still stumped :( Can you help?!
aniked [119]

ANSWER:

X\text{ = }\begin{bmatrix}{12} & {-4} & {-2} \\ {-8} & {-13} & {8} \\ {8} & {15} & {18}\end{bmatrix}

EXPLANATION:

Given:

U\text{ = }\begin{bmatrix}{1} & {3} & {-5} \\ {2} & {14} & {11} \\ {-8} & {0} & {5}\end{bmatrix}\text{           V =}\begin{bmatrix}{13} & {1} & {-7} \\ {-6} & {1} & {9} \\ {0} & {15} & {23}\end{bmatrix}

Since U and V are Matrices with equal dimensions(3 x 3 matrix), and

X + U = V.

To solve for X, we have:

X = V - U

\begin{gathered} X\text{ = V - U} \\ X\text{ = }\begin{bmatrix}{13-1} & {-1-3} & {-7-(-5)} \\ {-6-2} & {1-14} & {19-11} \\ {0-(-8)} & {15-0} & {23-5}\end{bmatrix}=\text{ }\begin{bmatrix}{12} & {-4} & {-2} \\ {-8} & {-13} & {8} \\ {8} & {15} & {18}\end{bmatrix} \end{gathered}X\text{ = }\begin{bmatrix}{12} & {-4} & {-2} \\ {-8} & {-13} & {8} \\ {8} & {15} & {18}\end{bmatrix}

Two objects are moving along separate linear paths where each path is described by position, d, and time, t. The variable d is m
zheka24 [161]

The equation of second graph is  d = 2.5 t + 1

We have given the linear equation is

d = 2.5 t +2.2,

If the graph of the position of the second object is parallel to

d = 2.5 t +2.2,

<h3>What is the  form of linear equation?</h3>

The equation of slope intercept form is

d=mt+b

compare the given equation with the slope intercept form

we get  m = 2.5

t = 0, d = 1

1 = 2.5 · 0 + b

b = 1

Therefore,the equation of second graph is  d = 2.5 t + 1
