Find the number, 112/ 100 of it is 56

1 answer:

6 0

First let that number be y.
List the equation by the given info.
y x 112/100 = 56
Shift y to the other side by turning it to ÷y.
112/100 = 56/y
Use cross method,
100 x 56 = 112y
5600 = 112y
y = 50
Therefore that number is 50

PLEASE ANSWER QUICKLY ASAP <br>ANSWER QUESTION A AND B

Evgen [1.6K]

Answer:

a) $a+b+c=\begin{pmatrix}-2\\-3\end{pmatrix}$

b) (i) $a+2c=\begin{pmatrix}-4\\2\end{pmatrix}$

(ii) $k=2$

Step-by-step explanation:

It is given that,

$a=\begin{pmatrix}4\\-10\end{pmatrix},b=\begin{pmatrix}-2\\1\end{pmatrix},c=\begin{pmatrix}-4\\6\end{pmatrix}$

We need to find the value of a+b+c.

$a+b+c=\begin{pmatrix}4\\-10\end{pmatrix}+\begin{pmatrix}-2\\1\end{pmatrix}+\begin{pmatrix}-4\\6\end{pmatrix}$

$a+b+c=\begin{pmatrix}4+(-2)+(-4)\\-10+1+6\end{pmatrix}$

$a+b+c=\begin{pmatrix}-2\\-3\end{pmatrix}$

(i) We need to find the value of a+2c.

$a+2c=\begin{pmatrix}4\\-10\end{pmatrix}+2\begin{pmatrix}-4\\6\end{pmatrix}$

$a+2c=\begin{pmatrix}4\\-10\end{pmatrix}+\begin{pmatrix}-8\\12\end{pmatrix}$

$a+2c=\begin{pmatrix}4+(-8)\\-10+12\end{pmatrix}$

$a+2c=\begin{pmatrix}-4\\2\end{pmatrix}$

(ii) It is given that a+2c=kb, where k is an integer. We need to find the value of k.

$a+2c=k\begin{pmatrix}-2\\1\end{pmatrix}$

$\begin{pmatrix}-4\\2\end{pmatrix}=\begin{pmatrix}-2k\\k\end{pmatrix}$

On comparing both sides, we get

$k=2$
