Answer:
1) 8.5
2) 60
3) 69.3
4) 6.8
5) 3.6
6) 10.5
Step-by-step explanation:
Take out the decimal of the estimated factors and multiply. Count how far to left the decimal is in the factors. In the product, put the decimal as many to the left as it was in the factors. (ex. 6.93 x 42, 6.93 rounds to 6.9, 42 rounds to 40, 69 x 40 = 2,760, move the decimal over one for correct place value, 6.9 x 40 = 276.0 <em>or </em>276)
If the question is asking how much Stacy has left it’s 500.

Paso uno:
datos dados
Sea xey el costo por libra de chispas de chocolate y nueces, respectivamente
por lo tanto
2x + 5y = 20 ------ 1
y
8x + 3y = 29 ------ 2
resolviendo 1 y 2 simultáneamente tenemos
2x + 5y = 20 (multiplicar la ecuación por 4)
8x + 20y = 80 ------------- 3
restar eqn 2 de 3
8x + 20y = 80 ------------- 3
8x + 3y = 29 ----------------- 2
0 + 17 años = 51
divide ambos lados por 17
y = 51/17
y = 3
El costo de las nueces por libra = $ 3
poner y = 3 en 8x + 3y = 29 ------ 2
8x + 3 (3) = 29 ------ 2
8x + 9 = 29
8x = 29-9
8x = 20
divide ambos lados entre 8
x = 20/8
x = 2,5
El costo del chocolate por libra = $ 2.5
