let's firstly convert the mixed fractions to improper fractions. and then let's make them with the same denominator by simply <u>multiplying each other by the other's denominator</u>.

$\bf \stackrel{mixed}{3\frac{1}{4}}\implies \cfrac{3\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{13}{4}}~\hfill \stackrel{mixed}{3\frac{4}{5}}\implies \cfrac{3\cdot 5+4}{5}\implies \stackrel{improper}{\cfrac{19}{5}} \\\\[-0.35em] \rule{34em}{0.25pt}$

$\bf \textit{now let's \underline{multiply each other by the other's denominator}} \\\\\\ \cfrac{13}{4}\cdot \cfrac{5}{5}\implies \cfrac{65}{20}\qquad \qquad \qquad \cfrac{19}{5}\cdot \cfrac{4}{4}\implies \cfrac{76}{20}~\hfill \cfrac{65}{20}$

3 4/5 because when you make the denominators equal by multiplying 1/4 by 5 on both sides and 4/5 by 4 and both sides you will get 5/20 and 16/20

MArishka [77]

Respuesta:

A.) BA = 12 m

Explicación paso a paso:

Usando triángulos similares:

BA / AC = DE / EC

BA = x; AC = 20; DE = 3; EC = 5

POR ESO ; TENEMOS :

x / 20 = 3/5

Multiplicar en cruz:

5 * x = 20 * 3

5 veces = 60

5x / 5 = 60/5

x = 12

Given that (9,-8) is on the graph of f(x), find the corresponding point for the function f(x-2)

MrRa [10]

Answer:

(11,-8)

Step-by-step explanation:

f(x-2) determines a horizontal translation 2 units to the right. Since (9,-8) is the point for f(x) then f(x-2) will be the point (11,-8) where 9 has moved two units to the right 11.

How do I round 4.75 up to the nearest whole number

Ksenya-84 [330]

4.75.
the whole number is 4
circle 4 and see whether the number beside it
in this case its 7
(Any number that is 5 - 9 causes the number that you are rounding off to to increase)
( any number that is 4-1 causes the number that you are rounding off too to remain)
in this case since its 7 which more that 5 and the whole number increases therefore the final answer is 5.

Hope this helps! xD
would not mind if you put it as the brainliest answer

*Correct Question:

Based on the similar triangles shown below, Theodore claims that ∆TUV is transformed to ∆WXY with a scale factor of 3/2. Is Theodore correct?

A. Yes, the triangles are similar with a scale factor of 3/2.

B. No, the triangles are similar with a scale factor of 2/1.

C. No, the triangles are similar with a scale factor of 2/3.

D. No, the triangles are similar with a scale factor of 4/3.

Answer:

C. No, the triangles are similar with a scale factor of 2/3.

Step-by-step explanation:

∆TUV is the original triangle. After transformation, the size reduced to give us ∆WXY. This means ∆TUV was reduced by a scale factor to give ∆WXY. The scale factor should be a fraction, suggesting, the original size of the ∆ was reduced upon transformation.

Thus, the ratio of their corresponding sides = the scale factor.

This is: $\frac{8}{12} = \frac{16}{24} = \frac{12}{18} = \frac{2}{3}$

If you multiply the side length of ∆TUV by ⅔, you'd get side length of ∆WXY.

So, Theodore is wrong.
