Use Desmos graphing calculator and plug in the different equations.
Answer: 8 units
Step-by-step explanation:
Set this up as an equation with a variable for turtles. Count up the other side of the scale (without turtles). Add up the three 1s and the 4 to get 7. Then add up all four 7s. This will get you with an equation 3t+4=28.
To solve this, first subtract 4 from both sides to get 3t=24. Now divide both sides by 3. 24/3=8. Each turtle weighs 8 units.
b, c, or d is correct because e > 4.8
explanation:
9+10e>57
you have to first leave 10e alone, so you take the opposite sign of the term that is on the same side as the variable and coefficient
57-9=48
so, the inequality will simplify to 10e>48
now all you have to do is isolate the variable e!
for that, simply divide 10 on both sides, one side will cancel out, the other side will come up with the quotient of 4.8
in conclusion, e>4.8
Answer
y = 2x +8
Step-by-step explanation:
Add 2
x to both sides of the first equation to get:
y
=
8
+
2
x
Divide both sides of the second equation by 2 to get:
y
=
8
+
2
x
The two equations determine the same conditions on xy so this system of equations has an infinite number of solutions, namely all points on the line:
y
=
2
x
+
8
Answer:
21 is common denominator.
15 and 7 are the corresponding numberators.
Step-by-step explanation:
You multiply the 7 and 6, then apply to the fractions, and slowly reduce until you find a good match.
