Answer:the price of one large gift is $60
Step-by-step explanation:
Let x represent the cost of one large gift.
Melanie bought 4 large gifts and 2 small gifts. Since each small gift costs $10, it means that the total amount that Melanie spent is
4x + 2×10 = 4x + 20
Mary bought 1 large gift and 20 small gifts. It means that the total amount that Mary spent is
x + 20×10 = x + 200
They both spent the same amount of money. This means that
4x + 20 = x + 200
4x - x = 200 - 20
3x = 180
x = 60
Find the volume 12•24•12=3456
And now 3456/8=432 so it’s the 2nd one
Answer:
x=8
Step-by-step explanation:
Make sure variables are on one side of the equation and numbers are on the other
-3x+7x=-20-12
-4x=-32
4x=32
x=8

Step-by-step explanation:
The angle shown is a right angle. Right angles have a total of 90°.
Therefore, I simply multiplied each answer by 4 because 4(x) = (answer).
A. 4 (14) = 56 + 42 = 98° ≠ 90° INCORRECT
C. 4 (10) = 40 + 42 = 82° ≠ 90° INCORRECT
B. 4 (16) = 64 + 42 = 106° ≠ 90° INCORRECT
D. 4 (12) = 48 + 42 = 90° = 90° CORRECT
An easier way to solve this problem is by simply just subtracting and dividing:
90 - 42 = 48
48 ÷ 4 = 12
