(3y+40)+(3x-70)=180
3y+3x-30=180
3y+3x=210
3(y+x)=210
y+x=70
x=70-y
meanwhile 180-120=x therefore x=60
therefore
60=70-y y=10
so x=60 y=10
Answer:
B. x, y, ac

Variables
Dependent and independent variables are variables in mathematical modeling, statistical modeling and experimental sciences. Dependent variables receive this name because, in an experiment, their values are studied under the supposition or hypothesis that they depend, by some law or rule (e.g., by a mathematical function), on the values of other variables. Independent variables, in turn, are not seen as depending on any other variable in the scope of the experiment in question. In this sense, some common independent variables are time, space, density, mass, fluid flow rate, and previous values of some observed value of interest (e.g. human population size) to predict future values (the dependent variable).
Number of apple trees is 16
(8×1=8 then 2×8=16 then 5×8=40)
pear trees is 15 for 1 orchard
pear trees is 75 for 5 orchard
you multiply the numbers 1 2 and 5 by 15 to find your answer
Answer:
I think it stands for congruence if your talking about logics and proofs but if your in the case of conjunctions and disjunctions then it would mean negating something.
Step-by-step explanation:
Answer:
1,2,3,4,5,6,7,8,9,10,11
Step-by-step explanation:
it's asking you possible values where e ( the number of eggs) would be greater/more than 0 but not more than 12. That would mean from 1 to 11 all numbers are possible.
