Answer:

B. 45

Step-by-step explanation:

To solve for angle A, we need to find the value of x. First, we need to find the interior angles of the triangle. We already know 2 of them, x+57 and 63+x but we need the third one. We can do that by subtracting 96 from 180 which is 84.

So now that we have the three interior angles of the triangle, we can make an equation. We already know that the sum of interior angles of a triangle is 180.

84+(x+57)+(63+x) = 180

Simplifying, we get:

204+2x=180

2x = -24

x=-12

Plugging x = -12 into x+57 gives 45 degrees. So, the answer is B.

Not sure how to make an equation for this problem. The equation I put was 86 - 8 = b x 2 = 156. But, it is starting that is inco
Elden [556K]

Answer:

b/2 + 8 = 86

b = 156

Step-by-step explanation:

Half the comics is b/2

b/2 + 8 = 86

Subtract 8 from both sides

b/2 = 78

multiply both sides by 2

b = 156

Please help with any of these, number 14, 16, 18 and 20 !!
kicyunya [14]

Answer:

14: B. 40 C. 40 D. 100

Step-by-step explanation:

a triangle is 180 degrees adding all the angles. The triangle on the top is just a mirror for the bottom and since B and C are the same that equals 80 and when you subtract 80 from 180 you get 100 so that makes D 100.

To double check just add 100+40+40=180

Chicken costs $3.20 per pound, and beef costs $4.59 per pound. How much more does 3 pounds of beef cost than 3 pound of chicken?
tensa zangetsu [6.8K]

To find the difference, first calculate how much 3 pounds of each meat costs.

$3.20 × 3 = $9.60 for 3 pounds of chicken

$4.59 × 3 = $13.77 for 3 pounds of beef

Now, take the difference.

$13.77 - $9.60 = $4.17

<h3>Answer:</h3>

3 pounds of beef costs $4.17 more than 3 pounds of chicken.
