Step-by-step explanation:

Mark the end of arrows

2-3/4
-4-1/4

So add them

$\\ \tt\hookrightarrow 2\dfrac{3}{4}+(-4\dfrac{1}{4})=-1\dfrac{2}{4}$

Answer:

B.) 2 3/4 + (-4 1/4) = -1 2/4

Step-by-step explanation:

blue line: forward with positive + $2\frac{3}{4}$

red line: backward with negative - $4\frac{1}{4}$

so the number line follows: $2\frac{3}{4}$ + - $4\frac{1}{4}$ = -1 2/4

Two brothers are sharing a certain sum of money in the ratio 2/3 : 3/5, if the largest share was Gh¢500.00. How much was shared

lina2011 [118]

Given:

Two brothers are sharing a certain sum of money in the ratio $\dfrac{2}{3}:\dfrac{3}{5}$ .

The largest share was Gh¢500.00.

To find:

The total amount shared between them.

Solution:

It is given that, two brothers are sharing a certain sum of money in the ratio $\dfrac{2}{3}:\dfrac{3}{5}$ .

First we need to make the denominators common.

$Ratio=\dfrac{2\times 5}{3\times 5}:\dfrac{3\times 3}{5\times 3}$

$Ratio=\dfrac{10}{15}:\dfrac{9}{15}$

$Ratio=10:9$

So, the two brothers are sharing a certain sum of money in the ratio 10:9.

Let the shares of two brothers are 10x and 9x respectively. So, the larger share is 10x.

It is given that the largest share was Gh¢500.00.

$10x=500$

$x=\dfrac{500}{10}$

$x=50$

Now, the total amount shared between them is:

$Total=10x+9x$

$Total=19x$

$Total=19(50)$

$Total=950$

Therefore, the total amount shared between them is Gh¢950.00.

Move triangle ABC so it lies on top of triangle DEF, triangle GHI, and triangle JKL. How many units do you have to move triangle

dusya [7]

Answer:

See explanation

Step-by-step explanation:

The question is incomplete, as the diagram of coordinates of the three triangles are not given.

A general explanation is as follows:

First, record the coordinates of the corresponding points of the three triangles.

For instance; In triangles ABC, DEF and GHI; A, D and G are corresponding points.

Now, assume the coordinates are:

$A = (1,1)$

$D = (1,5)$

$G= (-2,1)$

Point D is 4 points to the right of A;

i.e.

$D =(1,1+4) = (1,5)$

Hence, ABC will be moved 4 units right to lie on DEF

Similarly, point G is 3 units down of A

i.e.

$G =(1-3,1) = (-2,1)$

Hence, ABC will be moved 3 units down to lie on GHI.
