Paces tacos sold 280 food items from its mobile unit only tacos $2 each and burritos $3 each where available it took $660 in sal
trapecia [35]

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% = 0.3
0.3 • 250 = 75
75 of the participants were French.

Explain how you could use a number line to determine -5 -(-3)<br><br> What is the difference?
siniylev [52]

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.
