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
30% of the 250 participants were French.
To find how many this is, convert the percent to a decimal and multiply the decimal by the total number of participants.
30% = 0.3
0.3 • 250 = 75
75 of the participants were French.

Answer:
-2
Step-by-step explanation:
Start on -5 on the left side of the number line, jump from -5 three times to the right of the number line since ( - - ) means to add. As you jump draw "bridges" and by the time you have completed the amount of jumps you have to do you'll end up with a difference of -2.
The measures of the angles in a triangle always add up to 180°, so the answer is: m+p+n=180°.
