Answer:

150% increase

Step-by-step explanation:

18 + 18 = 36

Since it adds another 18, this is a 100% increase but we aren't dont yet

Now we add

36 + 9 = 45

Since 9 is 50% of 18, this is a 50% increase

Now we add the total increase in percentage, this is a 150% increase

Hope this helps

Is would be a 150% increase. Since your going from 18 to 45, your increase of percentage would be 150%, and the difference is 27.

Answer:

1520/49

Step-by-step explanation:

88+10= 98

next you have to solve the numbers on the right side using the order of operations. (PEMDAS)

98 x 30= 2940
2940 + 100= 3040

now you have solved the equations on both sides of the equal sign...

98=3040

the final step is to divide the numbers in order to get the solution...

3040/ 98 = 31.02040816

*if you need it in fraction form it is 1520/49

Hope I helped answer the question!

y = total amount saved

x = number of weeks

7 = constant

When x = 19

y = 7x

y = 7 * 19

y = 133

Their beginning time was 16.06 minutes.

Step-by-step explanation:

The track team is trying to reduce their time for a relay race.

First they reduce their time by 2.1 minutes, take it as $t_{1}$ . Then they are able to reduce that time by 10 minutes, take it as $t_{2}$ . Let ‘X’ be the time in minutes at the beginning.

Given that their final time is 3.96 minutes, then their beginning time can be calculated as below,

$X-t_{1}-t_{2}=3.96 \text { minutes }$

$X=3.96+t_{1}+t_{2}$

By substituting the values, we get

$X=3.96+2.1+10=16.06 \text { minutes }$

Hence, their beginning time was 16.06 minutes.
