Answer:
x = -2
y = 6
Step-by-step explanation:
i multiplied the 1st equation by 3 and the 2nd by 5 to get the y-terms to zero out
12x + 15y = 66
+ <u>35x - 15y = -160</u>
47x = -94
x = -94/47
x = -2
substitute -2 for 'x' to solve for 'y':
4(-2) + 5y = 22
-8 + 5y = 22
5y = 30
y = 6
The answer is C: the missing number is 25
Answer:
115.2 inches
Step-by-step explanation:
What we must do is calculate the ratio between the real version and the version to be imitated, in this case the ice cream cone.
To calculate the ratio, we will do it through the diameter:
48 / 2.5 = 19.2
So the ratio is 19.2: 1
Which means that one inch of the ice cream cone represents 19.2 inches in the real version.
Therefore, in the case of height it would be:
6 * 19.2 = 115.2
Therefore, the height should be 115.2 inches.
