Answer: 23 minutes
Step-by-step explanation:
4x + 8 = 100
100 is 8 more than 4 times of minutes than last week.
X = minuted she studied last week.
Find x
4x = 100 - 8
4x = 92
x = 92/4
x = 23 minutes
Answer:
2g+4
Step-by-step explanation:
Harvey is twice as old as Gwen. The equation for this is 2g.
If we need to find Jennifer's age, which is 4 years older than Harvey, then we need to add 4 to Harvey's age.
2g+4
The perpendicular line through (2, 1) is
.. y = (x -2)+1
or
.. y = x -1
Answer:
i. 5 + 4 = 9
ii. 2 x 3 = 6
iii. 8 - 7 = 1
Step-by-step explanation:
Given: The basic arithmetic operations: addition, subtraction, multiplication or division.
Digits from 1 - 9
Using three arithmetic operations - addition, subtraction, multiplication, and the given digits, the following three expressions can be formed:
i. 5 + 4 = 9
ii. 2 x 3 = 6
iii. 8 - 7 = 1
It can be observed that there is no repetition of digits in the above expressions as required.
The answer is 2/(15*0.8) hours = 2/12 hours
= (2/12)*60 mins [ 1 hour = 60 mins]
= 10 mins
