The coefficient is 2 and
The variables are x and y
Multiply 2x and 3y to identify the solution.However,that cannot be done because we would need the value of x and to subsitute the variables.
Answer:
4 sophomore girls .
Step-by-step explanation:
If a student's gender and class are to be independent when a student is selected at random, two conditions must be met:
n° boys = n° girls
n° freshmen = n° sophomore
Currently, there are 10 boys and 6 girls, thus 4 girls must join.
Currently, there are 10 freshmen and 6 sophomores, thus 4 sophomores must join.
Therefore, 4 sophomore girls must join.
Answer:
I think its 24.86 mph
Step-by-step explanation:
n= speed of train
3*58=174 distance car traveled in 3 hours and train traveled in 7 hours
7n=174
n=174/7=24.86 mph
Answer: The correct option is D, i.e., 5.
Explanation:
Dilation is defined as the enlargement or compression of a figure along the center of dilation according to the scale factor k.
If k>1 then it shows the enlargement and if 0<k<1 then it shows the compression.
If k is negative the image and preimage lies on the opposite sides of center of dilation.
The image and preimage are similar to each other and the sides are in the proportion of k.
In the given figure the length of side CA is 4 unit.
The image of CA is CA' and its length is,
Since the given figure shows the enlargement, so k>1.
Therefore, the value of k is 5 and D is the correct option.
