Answer:
11x
Step-by-step explanation:
They have the same variable so just add the two numbers
Answer:
5 folders and 5 pens = yes
6 pens and 6 erasers = yes
1 pen and 4 notebooks = no
3 folders and 7 erasers = no
4 folders and 2 notebooks = yes
Step-by-step explanation:
Max total = $10
(5 folders x 1.29) + (5 pens x 0.70)
6.45 + 3.50 = 9.95
(6 pens x 0.70) + (6 erasers x 0.89)
4.20 + 5.34 = 9.54
(1 pen × 0.70) + (4 notebooks × 2.35)
0.70 + 9.40 = 10.10
(3 folders × 1.29) + (7 erasers × 0.89)
3.98 + 6.23 = 10.21
(4 folders × 1.29) + (2 notebooks × 2.35)
5.16 + 4.70 = 9.86
Answer:
7.8 × 10^-4
Step-by-step explanation:
Although this answer is perfectly O.K., most commonly the base, or the 0.00078, is written as a number with just one digit to the left of the decimal.
To format your number in this way, we'll multiply the .00078 by 10, 4 time(s), making it a 7.8.
We do this, because each multiplication by 10 moves the decimal point to the right one digit.
But in order to keep our number the same number, we must have a × 10-4 next to the 7.8.
So, the final answer is 7.8 × 10^-4
Answer:30
Step-by-step explanation:
Find the prime factorization of 6
6 = 2 × 3
Find the prime factorization of 10
10 = 2 × 5
Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the lcm:
LCM = 2 × 3 × 5
LCM = 30
