Answer:
you find the x and y intersepts and draw the line
Step-by-step explanation:
if we break down the equasion in the end it's y=x+4 and from there we can find the intersepts by canceling out, y=x+4 becomes y=4 and 0=x+4 wich is x=-4
If the amount of monkeys is m, lions is a, and lizards is b, then a+b+m=151, 17+a=m (since there are 17 more monkeys than lions), and 30+a=b. Substituting those values in (17+a=m and 30+a=b), we have 30+17+a+a+a=151=47+3a. Subtracting 47 from both sides, we get 104=3a. Next, we can divide both sides by 3 to get 104/3=a (the number of lions), 104/3+17=the number of monkeys, and 104/3+30=the number of lizards. Somehow we end up with a fraction (not a whole number), so there are 2/3rds of monkeys floating around using this logic.
Answer:
m∠EBC=34°
Step-by-step explanation:
we know that
m∠DBC=m∠DBE+m∠EBC
see the attached figure to better understand the problem
substitute the given values in the formula and solve for x
Find the measure of angle EBC
m∠EBC=(3x+13)°
substitute the value of x
m∠EBC=(3(7)+13)°
m∠EBC=(21+13)°
m∠EBC=34°
