Answer:
x = 9
Step-by-step explanation:
Since you have a equilateral triangle all angles are 60°.
7x - 3 = 60
7x = 60+3
7x = 63
x = 63/7
x = 9
Okay, since the problem states that they're going to make 4 times the recipe and the recipe is 2/3, You have to multiply 2/3 x 4/1 which equals to 8/3, When you convert it into a mixed numbe you have 2 2/3, Hope I helped.
It would be 5.53 because the 1 after the 3 is smaller than 5.
F(x) = 1/x and g(x) = -10/x
Domain: same: all real numbers other than x=0.
Range: strictly speaking, these 2 functions have the same range: all real numbers other than y=0. But the graph of g(x) = -10/x looks stretched vertically when compared with that of f(x) = 1/x.
Answer:
The answer to your question is there were 88 children
Step-by-step explanation:
Data
Total number of people = 188
total cost = $5040
12 more adults than seniors
number of children = ?
adults = a
children = c
Process
1.- Write equations that help to solve this problem
a + c = 188 Equation l
a = c + 12 Equation ll
2.- Solve by substitution. Substitute equation equation ll in equation l
(c + 12) + c = 188
-Solve for c
c + 12 + c = 188
2c + 12 = 188
2c = 188 - 12
2c = 176
c = 176 / 2
c = 88
3.- Conclusion
There were 88 children
