Norman buys lunch for his employees at the El Camion Food Truck every Friday. Last week, he purchased 8 tacos and 5 burritos and

serg [7]

Answer:

1 taco costs $1.5 and 1 burrito costs $3.25

Step-by-step explanation:

-Let t denote tacos and b denote burritos.

-The system of equations in the two weeks can then be expressed as below:

$8t+5b=28.25\ \ \ \ \ \ ...i\\\\7t+7b=33.25\ \ \ \ \ \ ...ii$

make t the subject of the formula in i and then substitute in ii to solve for both unknowns:

$8t=28.25-5b\\\\t=\frac{1}{8}(28.25-5b)\\\\\\\therefore 7t+7b=33.25\\\\\frac{7}{8}(28.25-5b)+7b=33.25\\\\\\24.71875-4.375b+7b=33.25\\\\8.53125=2.625b\\\\\\b=3.25\\\\t=\frac{1}{8}(28.25-5\times3.25)=1.5$

Hence, 1 taco costs $1.5 and 1 burrito costs $3.25

What values of b satisfy 4(3b + 2)2 = 64?

rodikova [14]

Assuming yo meant
4(3b+2)²=64

divide both sides by 4
(3b+2)²=16
sqrt both sides
remember to take positive and negative roots
3b+2=+/-4
minus 2 both sides
3b=-2+/-4
divide by 3
b=(-2+/-4)/3
b=(-2+4)/3 or (-2-4)/3
b=2/3 or -6/3
b=2/3 or -2
