Answer:
2
Step-by-step explanation:
GCF stands for the "greatest common factor." Therefore because 2 can go into both 2 and 4 evenly, it is the GCF.
Multiply 190 by 0.27 and you should get your answer
Answer: Aiden bought 8 notebooks and 5 covers.
This is a system of equations problem. To solve this, we have to write 2 different equations and then solve them.
Our equations are:
x + y = 13
1.37x + 1.08y = 16.36
Where x is the number of notebooks and y is the number of covers.
To solve these equations, you can use anyone of these methods:
1) Graphing
2) Substitution
3) Elimination
The easiest way would be to graph them with a graphing calculator and find the point of intersection.
Answer:
b = 33°
Step-by-step explanation:
A full circle is 360°.
360° - 296° - 31° = b
360° - 296° - 31° = 33°
Answer:
180 tacos and 100 burritos was sold
Step-by-step explanation:
Let <em>t</em><em> </em>represent tacos
Let <em>b</em><em> </em>represent burritos
<em>t</em><em> </em>+ <em>b</em><em> </em>= 280
<em>2t</em><em> </em>+ <em>3b</em><em> </em><em>=</em><em> </em><em>660</em>
From t + b = 280,
t = 280 - b
Substitute t = 280 - b in 2t + 3b = 660
2t + 3b = 660
2(280 - b) + 3b = 660
560 - 2b + 3b = 660
560 + b = 660
b = 660 - 560
b = 100
Substitute b = 100 in t + b = 280
t + b = 280
t + 100 = 280
t = 280 - 100
t = 180
t = tacos = 180
b = burritos = 100
