Answer:

$- 8(y - 2) = 160 \\ - y + 2 = 20 \\ - y = 18 \\ y = - 18$

Step-by-step explanation:

Just because before y there is negative "-" thus youve got to put it before 18. Eventually the answer is -18,not 22

What is heavier 85 g or 3 oz

kati45 [8]

To compare measurements of different units, it is necessary to convert one to the form of the other. Let us try to convert 85g to ounces using the following relation: 1g = 0.035274 oz

85g * (0.035274oz / 1g) = 2.99829 oz.

Therefore, 3 oz is heavier than 85 g.

Find the measure of angle B.

Assoli18 [71]

Step-by-step explanation:

C = 180 - 112 = 68°

A = 180 - 68 - 51 = 61°

B = 180 - 61 = 119°

Another way :

We know that B = C + 51 ==> B = 68 + 51 = 119°
