Step-by-step explanation:

= 1 \frac{1}{5}  +  \frac{3}{4}  - ( - 3 \frac{3}{5} ) - ( - 2 \frac{1}{4} )

= 1 \frac{1}{5}  +  \frac{3}{4}  + 3 \frac{3}{5}  + 2 \frac{1}{4}

= (1 + 3 + 2) + ( \frac{1}{5} +  \frac{3}{4} +  \frac{3}{5}   +  \frac{1}{4}  )

= 6 + ( \frac{4 + 15 + 12 + 5}{20} )

=  6 +  \frac{36}{20}

= 1 + 6 +  \frac{16}{20}

= 7 +   \frac{4}{5}

= 7 \frac{4}{5}

Answer:

The answer is 61/10

Step-by-step explanation:

1 1/5 + 3/4 - (- 3 3/5) - (- 2 1/4)

1 × 5 + 1/5 + 3/4 - (- 3 × 5 + 3/5) - (- 2 × 4 + 1/4)

6/5 + 3/4 + 12/5 + 7/4

6/5 + 12/5 + 3/4 + 7/4

(6 + 12/5) + (3 + 7/4)

18/5 + 10/4

18/5 + 5/2

Now, Cross Multiply

18 × 2/5 × 2 + 5 × 5/2 × 5

36/10 + 25/10 = 61/10

Thus, The answer is 61/10

Robert says the expression 2+3 times 7 and 2+(3 times 7) have the same value. Is Robert correct? Explain your answer and evaluat
erastovalidia [21]
Yes because you multiply first so in this case you multiply 7 and 3 first. Since the second expression is in parenthesis you do that first just like you do 7 times 3. Then you just add 2 to that. The value of both expressions is 23

Mnenie [13.5K]

Answer:

The answer is 10y + 48.

Step-by-step explanation:

First you have to get rid of brackets by expanding :

y + 3 + 9(y + 5) \\  = y + 3 + 9y + 45

Next you have to collect like-terms :

y + 3 + 9y + 45 \\  = 10y + 48

Jake's time for the 100 meter race was 11.46. Dan's time was faster. Which could be Dan's time?
MrRissso [65]
Anything smaller than 11.46. Decimal and whole number wise.

This is because it says Dan’s time was faster, meaning he took less time then Jake, thus making it so the time has to be smaller than 11.46.

Hope this helps!

Is the point (16,20) on line ℓ?<br><br><br>​
kicyunya [14]

Answer:

YES

Step-by-step explanation:

Find the equation of the line written as, y = kx. The graph shows a proportional relationship between y and x.

Constant of proportionality/unit rate/slope (k) = rise/run = ⁵/4.

Substitute ⁵/4 in y = kx

We would have:

y = ⁵/4x.

Using the equation of the line, we can know if a given point is on the line by plugging the value of x and y coordinates of the point into the equation. If it makes the equation true, then it is a point on the line. If it doesn't make the equation true, then it isn't a point on the line.

Let's plug in (16, 20) into y = ⁵/4x.

Thus substitute x = 16 and y = 20, we have:

[tex] 20 = \frac{5}{4}(16) [/trex]

[tex] 20 = (5)(4) [/trex]

[tex] 20 = 20 [/trex]

It makes the equation true. Therefore, the point, (16, 20) is a point on line l.
