Correct. They only want to know how many are 5 cm tall. So we only need to count the 'x' 's in the 5 area, which are 6. You are correct
Answer=6
7B + 4 = 7B - 3
We need to solve for B
Let's add 3 in both sides:
7B + 4 = 7B - 3
7B + 4 + 3 = 7B - 3 + 3
7B + 7 = 7B
Let's subtract 7B from both sides:
7B + 7 = 7B
7B - 7B + 7 = 7B - 7B
7 = 0
7 = 0, which is impossible. 7 can never be 0, and 0 can never be 7.
So the equation have no solution.
23 plus 7 is 30 and 30 plus 5 is 35
Answer:
3.6
Step-by-step explanation:
Answer:
1/9
Step-by-step explanation:
4 green marbles, 5 red marbles, and 6 blue marbles in a bag = 15 marbles
P(red)= number of red/ total = 5/15 = 1/3
Put it back in the bag
4 green marbles, 5 red marbles, and 6 blue marbles in a bag = 15 marbles
P (red)= number of red/ total = 5/15 = 1/3
P(red, replace, red) = P(red) * P(red) = 1/3*1/3 = 1/9
