Answer:
The first mechanic charges $105 per hour, and the second mechanic charges $90 per hour.
Step-by-step explanation:
If x is the rate of the first mechanic, and y is the rate of the second mechanic, then:
10x + 5y = 1500
x + y = 195
Solve the system of equations using elimination or substitution. Using substitution:
10x + 5 (195 − x) = 1500
10x + 975 − 5x = 1500
5x = 525
x = 105
y = 195 − x
y = 90
The first mechanic charges $105 per hour, and the second mechanic charges $90 per hour.
I think it is at 23 degrees (I am really sorry if I am wrong)
For problems involving algebra, you have to formulate algebraic equations to be able to solve the problem. Algebraic equations are mathematical terms which include variables to denote the unknown numbers.
For this problem, you are to find the total cost which consists of cost for the gun rent and cost for the paintballs. Hence, your equationmust consist of two terms. The equation must be:
Total cost = 100x + 1000
The term x denotes the number of guns. Hence, it must be multiplied with 100 to determine the cost. On the otherhand, the constant 1000 is for the paintballs. Since it was given that each team must have 2000 paintballs, then it follows that they must pay 1000 Php.
Answer:
8
Step-by-step explanation:
since it is a cube the all sides are equal
v=a³
512 = a³
a=³√512
a=8
the length of the rock=8
