Answer:
71 degrees
Step-by-step explanation:
All angles in a triangle must add up to 180 degrees. If we take that total 180 and subtract 38, we get 142 degrees. If we divide that by two, because the angles are the same, we get 71 degrees. Therefore x=71

Answer:
Step-by-step explanation:
the bat is 12. the pumpkin is 5. and the weird looking thing is 14
14 plus 14 plus 12 is 40
12 minus 5 is 7
5 plus 14 is 19
14 minus 5 plus 12 is 21
Answer:
21
Step-by-step explanation:
Green bat: x
Purple bat: y
Pumpkin: z
Given:
2x + y = 40
y - z = 7 ===> y = 7 + z
z + x = 19 ===> z = 19 - x
Substitution to find green bat x:
2x + y = 40
2x + (7 + z) = 40
2x + 7 + z = 40
2x + 7 + (19 - x) = 40
2x + 7 + 19 - x = 40
x + 26 = 40
green bat: x = 14
Substitution to find pumpkin z:
z + x = 19
z + (14) = 19
z + 14 = 19
pumpkin: z = 5
Substitution to find purple bat y:
y - z = 7
y - (5) = 7
y - 5 = 7
purple bat: y = 12
Solve for x - z + y:
14 - 5 + 12 = 21
A metallurgist wants to make 130 grams of an alloy that is to be 20% copper. She has samples that are 14% copper and 22% copper. How many grams of the sample that contains 14% should she use?
Answer:
She should use 32.5 g of the sample that contains 14%
Step-by-step explanation:
Here, we want to know the number of grams of the sample that contains 14% copper that should be used
let the number of grams that contains 14% copper to be used be x
Then the number of grams of 22% will be 130-x
Thus, mathematically;
0.14(x) + 0.22(130-x) = 0.2(130)
0.14x + 28.6 - 0.22x = 26
0.22x - 0.14x = 28.6 - 26
0.08x = 2.6
x = 26/0.08
x = 32.5

then it says minus the number so 7x-x is equal to -48
7x-x=-48; combine the x's
6x = -48; now divide by 6
x = -8
Answer:
The anwser would be A: -8
Step-by-step explanation:
7 x -8 = -56
-56 - (-8) = -48

Rich and Betsy Cuik started a small business. They manufacture a microwavable coffee-to-go cup called Cuik Cuppa Coffee. It contains spring water and ground coffee beans in a tea-bag-like pouch. Each cup costs the company $1.00 to manufacture. The fixed costs for this product line are $1,500. Rich and Betsy have determined the demand function to be q = -1,000p + 8,500, where p is the price for each cup.
Write the expense equation in terms of the demand, q.
Express the expense equation found in part (a) in terms of the price, p.
Answer: E= 1.00q + 1,500

A 1/2 cup serving of ice cream contains 140 calories. How many calories would be in a 3/4 cup serving?
Answer:
There would be 210 calories in a 3/4 cup serving.
Step-by-step explanation:
1/2 of 140 = 70
70 = 1/4
70 x 3 = 210 = 3/4
I hope this helped you! If it did, please consider pressing thanks, rating my answer, and marking as Brainliest. It would be a big help! Have a great day! :)
Based on the number of calories in 1/2 cups, the number of calories in 3/4 cups is 210 calories.
Number of calories in 3/4 cupYou can use direct proportion to solve for this by assuming that the calories in 3/4 cups is x:
1 / 2 : 140 calories
3 / 4 : x
Cross multiplying would give:
1/2x = 105
x = 105 ÷ 1/2
x = 210 calories
In conclusion, there would be 210 calories in 3/4 cups.
