Answer:
The correct answer is A) 3x - 2
Step-by-step explanation:
In order to find this, take the value of JM and subtract the value of LM. This will give you JL.
JM - LM = JL
5x - 8 - (2x - 6) = JL
5x - 8 - 2x + 6 = JL
3x - 2 = JL
Answer:
C, or the third choice would be correct
Step-by-step explanation:
Answer:
25.7 feet.
Step-by-step explanation:
Let x be the actual length of tree.
We have been given that in sunlight, a vertical stick 7 ft tall casts a shadow 3 ft long. We are asked to find the actual length of tree casting a 11 ft long shadow.
We will use proportions to solve our given problem.
Upon multiplying both sides of our equation by 11, we will get:
Therefore, the tree is 25.7 feet tall.
Answer:
50 boys
Step-by-step explanation:
The number of groups = 24
The average number of children = 16
The new average number of children when one group is added = 18
The ratio of boys to girls in the group that just joined = 5:6
The initial number of boys = 220
Let the initial number of children
The initial total number of children = 24 × 16 = 384
The initial number of girls = 384 - 220 = 164
The final number of children = 25 × 18 = 450
The number of children in the group that joined in the game = 450 - 384 = 66
The ratio of boys to girls in the group = 5:6
Therefore, we get;
The number of boys = 66 × 5/11 = 30
The number of girls = 66 - 30 = 36
The number of boys at the end = 220 + 30 = 250
The number of girls at the end = 164 + 36 = 200
The number of more boys than girls at the end = 250 - 200 = 50
The number of more boys than girls at the end = 50 boys
a - 6b + 4c
a - 10b + 4c
-a + 10b + 4c
