jamie wants to run a total of 9 miles thid week. so far, she has run 4 5/8 miles. use the equation 4 5/8 + r = 9​. please help m
____ [38]

Answer:

r=4\frac{3}{8}

Step-by-step explanation:

Given the following question:

4\frac{5}{8} +r=9

<u>Rewrite the expression to find the value of r:
</u>
9-4\frac{5}{8}

<u>Subtract by finding the common denominator:</u>
9-4\frac{5}{8}
9=\frac{9}{1}
4\frac{5}{8} =8\times4=32+5=37=\frac{37}{8}
\frac{9}{1} -\frac{37}{8}
\frac{9}{1} \times8=\frac{72}{8}
\frac{37}{8} \times1=\frac{37}{8}
\frac{72}{8} -\frac{37}{8}
72-37=35
=\frac{35}{8}
\frac{35}{8} =35\div8=4\frac{3}{8}
r=4\frac{3}{8}
4\frac{5}{8} +4\frac{3}{8} =9

Hope this helps.

I need help with this problem
Soloha48 [4]

Answer:

3.\ \dfrac{3x}{11x}, \dfrac{6}{22},  \dfrac{9}{33},\dfrac{12}{44}

4. -18\\5.\ 400

Step-by-step explanation:

<u>Solution 3:</u>

Equivalent fractions to are to \frac{3}{11} be found out.

<u>Method: </u> By Multiplying both the denominator and numerator with the same number, we can easily find equivalent fractions.

1. Multiply with 2:

\dfrac{3 \times 2}{11 \times 2}\\\Rightarrow \dfrac{6}{22}

2. Multiply with 3:

\dfrac{3 \times 3}{11 \times 3}\\\Rightarrow \dfrac{9}{33}

3. Multiply with 4:

\dfrac{3 \times 4}{11 \times 4}\\\Rightarrow \dfrac{12}{44}

If we try to write in variable form, it can be written as:

\dfrac{3x}{11x}

where x is any number.

---------------

<u>Solution 4:</u>

(2x-10) when x=-4

2 \times (-4) -10\\\Rightarrow -8 -10\\\Rightarrow -18

------------

<u>Solution 5:</u>

(10a)^2, a=-2\\\Rightarrow \{10 \times (-2)\}^2\\\Rightarrow (-20)^2\\\Rightarrow 400

If point k is at (-3,2) where will it be when it is reflected over the line y=1 and then rotated 90 degrees?
Andrei [34K]

Answer:

(0,-3)

Step-by-step explanation:

(-3,2) reflected over the line y=1 is (-3,0)

Now rotated 90 degrees over what, and in which direction?

Im going to assume that the rotation is counter clockwise over the origin because that is standard when not mentioned. ¯\_(ツ)_/¯

That would be: (0,-3)

Yw! :D
