Answer:

Emilio will have both activities again on the same day after 90 days from this Saturday.

Step-by-step explanation:

<em>To solve this question list the multiples of 30 and 9 to find the first common multiple because the two activities will happen again in </em><em>a number divisible by both 30 and 9.</em>

∵ The multiples of 30 are: 30, 60, 90, 120, ............

∵ The multiples of 9 are: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, .....

→ The common multiple is 90

∴ The common multiple of 30 and 9 is 90

→ That means the activities will meet again after 90 days from

this Saturday

Emilio will have both activities again on the same day after 90 days from this Saturday.

Marneshia walked three over eight of a mile in three over five of an hour. What equation can be used to calculate her unit rate

Rama09 [41]

3/8 mile in 3/5 hour
$\frac{ \frac{3}{8} }{ \frac{3}{5} }$
we want to find miles per hour or m/1h
convert 3/5 to 1 by multiplying it by 5/3
keep the fraction the same by multiply ing the whole thing by
$\frac{ \frac{5}{3} }{ \frac{5}{3} }$ to get

$\frac{ \frac{15}{24} }{ \frac{15}{15} }$ =
$\frac{ \frac{5}{8} }{ 1}$ =5/8 miles per hour

7x10 to the 3rd power, write a pattern to find the value of the expression

myrzilka [38]

Scientific notation is used to express very large or very small values.
Numbers in scientific notation are written in the form of
m × 10 to the power of n
For example:
500 is written as 5 x 10^2 where:
500 = 5 x 10 x 10

Now, let's consider 7 x 10^3:
Following the same procedure:
7 x 10^3 = 7 x 10 x 10 x 10 = 7000
The pattern can be written as:
7 x 10^3 = 7 x 10 x 10^2
= 70 x 10^2
= 70 x 10 x 10^1
= 700 x 10
= 7000

What is the first step in solving 2x=y X+y=30

Vanyuwa [196]

Answer: x = 10 y=20

Step-by-step explanation:

You can answer this question by plugging in each equation:

2x=y, x+y=30. Let us plug y as 2x in the second equation x+y=30

x+2x= 30

3x= 30

x=10

After we found x we can then find y by plugging the 10 for x.

2(10) = y

y =20

or you could plug in the other equation

10+y=30

subtract 10 from 30 and we get 20

to double check we can plug in both numbers

2(10) = 20 which is correct

and 10 + 20 = 30 which is correct
