In 15 minutes Frankita created 15 drawings. In 30 minutes she created 17 drawings. In 45 minutes she created 20 drawings. In 60

SVETLANKA909090 [29]

Answer:

Frankita will create 29 drawings at the end of 75 minutes.

Step-by-step explanation:

Now below shown is the pattern used by Frankita:

15 min = 15 drawing

30 min = 17 drawing ⇒ increase by 2 (15+2 = 17)

45 min = 20 drawing ⇒ increase by 3 (17+3 = 20)

60 min = 24 drawing ⇒ increase by 4 (20+4 = 24)

75 min = 29 drawing ⇒ increase by 5 (24+5 = 29)

Hence We can say that Frankita will create 29 drawings at the end of 75 minutes.

A point is refected across the x-axis. The new point is (5,-3.5).What is the distance between the two points?

Vesna [10]

When a point is reflected across the x-axis, it's y value is flipped. Here is a formula for your future reference:

X-axis reflection: (x,-y)

Using your given coordinates, you simply plug the numbers in, resulting in final coordinates of (5,3.5).

Because the problem asks for the distance between the two points, you now have to find the difference between -3.5 and 3.5, which is 7.

There you go; the distance between the points is 7 units.

1. N - 80 = 40 2. 15n = 30 3. N + 284 = 350 4. 6 + 9 = 3 x n 5. N divided by 3 = 6 +1 6. 12 - 8 = n divided by 5 7. 58 x 6 = n -

kkurt [141]

Answer:

1. $N=120$

2. $n=2$

3. $N=66$

4. $n=5$

5. $N=21$

6. $n=20$

7. $n=1398$

8. $n=5$

Step-by-step explanation:

$N-80=40$

$N=40+80$

$N=120$

$15n=30$

$\dfrac{15n}{15}=\dfrac{30}{15}$

$n=2$

$N+284=350$

$N=350-284$

$N=66$

$6+9=3\times n$

$15=3n$

$\dfrac{15}{3}=n$

$n=5$

$\dfrac{N}{3}=6+1$

$\dfrac{N}{3}=7$

$N=7\times 3$

$N=21$

$12-8=\dfrac{n}{5}$

$4=\dfrac{n}{5}$

$4\times 5=n$

$n=20$

$58\times 6=n-(723 + 327)$

$348=n-1050$

$348+1050=n$

$1398=n$

$4n+12=(7+9)\times 2$

$4n+12=16\times 2$

$4n+12=32$

$4n=32-12$

$4n=20$

$n=\dfrac{20}{4}$

$n=5$

Therefore, the solutions are 1. $N=120$

2. $n=2$

3. $N=66$

4. $n=5$

5. $N=21$

6. $n=20$

7. $n=1398$

8. $n=5$

On a standardized test, Rall answered the first 22 questions in 5 minutes. There are 77 questions on the test. If he continues t

Rasek [7]

Data:
Questions = 77
Anwered = 22
Missing = 77 - 22 = 55

Solving:

Questions ________ Time
22 -------------------------- 5
55 -------------------------- t

Multiply cross:

$22*t = 55*5$
$22t = 275$
$t = \frac{275}{22}$
$\boxed{t = 12,5minutes}$
