Answer:
(10, 14)
Step-by-step explanation:
To solve this system let's use substitution:
Solve the first equation for x, obtaining x = 24 - y, and then substitute 24 - y for x in the second equation:
3(24 - y) + 5y = 100
Performing the indicated multiplication, we get:
72 - 3y + 5y = 100
Combining like terms results in 72 - 100 = -2y, or -28 = -2y
Thus, y must be 14.
If y = 14, then the first equation tells us that x = 10.
Check: Is this true? 3(10) + 5(14) = 100 YES
The solution is (10, 14).

√49 = 7 7 is a rational number, also a whole number as well, how bout that.</span>
Answer:

Step-by-step explanation:
.05+1.2(.11-.05)
.05+1.2(.06)
.05+.072 = .122
Answer:
The length of side a is 30
Step-by-step explanation:
because the side of an angle is the side it's pointing at which is BD. BD = a = 30
Answer: 360
Step-by-step explanation:
Since we are informed from the question that Alicia surveyed 50 students in the cafeteria from the population of 300 students, it simply means that she surveyed 50/300 = 1/6 of the students.
Since Thea surveyed the first 60 students who arrived at school one morning, the number of T-Shirts taht they should order will be:
= 1/6 × x = 60
x = 60 × 6.
x = 360
They should order 360 t-shirts for the students.
