Answer: 30=2x+4 and there are 17 girls in the class.
Step-by-step explanation: if x+4=[total girls] and x=[total boys] and 30=[total kids], then x+4+x = 2x+4 = [total kids], since total kids id 30 then our equation is 30 = 2x + 4 and x= 13boys so 30-13= 17girls.
It's BASIC prealgebra so you should probably practice bit more with linear equations!
Answer:
Starting 6 inches in front of the rubber, or 60 feet from home plate, the mound slopes downward at a rate of 1 inch per foot over a span of at least 6 feet. It is very important that the mound be maintained in good condition. The pitcher depends on having good footing on the mound, and he may be injured he slips during his delivery.

Answer:
C. The likelihood of getting these results by chance is very small.
Step-by-step explanation:
When the finding of a statistical analysis of data is said to be statistically significant, it simply means that the likelihood of getting these results by chance is very small.
This ultimately implies that, an experiment or research is statistically significant when its results or outcomes isn't likely to occur by chance or randomly rather it is associated with a specific cause.
Generally, when the p-value is very small (less than or equal to 0.05) then the result of a research or experiment is considered to be statistically significant and reliable.

Answer:
Nestor can pot 6 plants in 1 hour.
Step-by-step explanation:
first lets convert 2 1/2 hours in mixed fraction form for better calculation
2 1/2 hours = (2*2 + 1)/2 = 5/2 hours
no of plants pot in 5/2 hours = 15
to find no. of plants pot in 1 hours lets
divide both side by 5/2
no of plants pot in 5/2/(5/2) hours = 15/(5/2) = 15*2/5 = 6
no. of plants pot in 1 hour = 6
Thus, Nestor can pot 6 plants in 1 hour.
