4 x = 36
Step-by-step explanation:
Because the groups have an equal number of students, we assume that each of the groups has <em>x </em>number of students.
Therefore since there is <em>x</em> number of students in each of the 4 groups, there is 4 * x number of total students in all groups combined.
Since the question already indicates that there are a total of 36 students in the class, then we can indicate that..
4x = 36
Answer:
x = -1
y = 2
Step-by-step explanation:
y = x+3
x+2y = 3
substitute y
x+2(x+3) = 3
simplify
3x+6 = 3
subtract 6 from both sides
3x = -3
x = -1
y = -1+3 = 2
Answer:
Cost of ordering t-shirts the same at both sides is 7
The cost is $85
Step-by-step explanation:
let x equal the number of tshirts
Hence:
15 + 10x = 50 + 5x
10x-5x= 50-15
5x = 35
35/5x
x = 7
Therefore the cost of ordering t-shirts the same at both sides is 7
The cost is $85
65 yards because of a2+b2=c2
