Solve the system by substitution.
y = 5x
y = 9x + 4
Answers
Answer:
(-1, -5)
Step-by-step explanation:
[tex]\left \{ {{y=5x} \atop {y=9x+4}} \right.[/tex]
1. We must calculate x, for that we must substitute y, so we have:
5x=9x+4
2. Now we solve the equation.
5x-9x=4
-4x=4
x=-1
3. Now we must calculate y
y=5x
y=5(-1)
y=-5
And the answer is (-1, -5)

The ratio of the measure of the three angles of a triangle is 3:4:8. Find the mesure of the large angle
Answers
Answer:
96°
Step-by-step explanation:
Ratio of angles :
3 : 4 : 8
Sum of angles in a triangle = 180°
The value of the largest angle = angle with the largest ratio
This is the value of the angle with ratio 8
Sum of ratio : (3 + 4 + 8) = 15
Hence,
(8 / 15) * 180°
(8 * 180°) / 15
1440 / 15
= 96°

At a restaurant, the cost for one breakfast taco and one glass of milk is $2.10.
The cost for two tacos and three glasses of milk is $5.15.
How much would it cost for 3 tacos and 4 glasses of milk
Answers
Answer: $7.25
Step-by-step explanation:
Let T = taco cost
Let M = milk cost
T + M = 2.10
2T + 3M = 5.15
Multiply the first equation by (-2) and add it to the second equation
-2T - 2M = -4.20
2T + 3M = 5.15
M = 0.95
Plug this value for M in to the first equation
T + 0.95 = 2.10
T = 1.15
So a taco costs $1.15 and the milk costs $0.95
1.15 * 3 = 3.45
0.95 * 4 = 3.80
3.45 + 3.80 = 7.25

A company makes steel rods shaped like cylinders. Each rod has a diameter of 8 centimeters and a height of 20 centimeters. If the company used 28,134.4 cm3 of steel, how many rods did it make?
Answers
Answer:
1,172.3 cm³
Step-by-step explanation:
Find the volume of one rod, then divide the total volume of steel used by the volume of one rod. The volume of one rod is
V = (πd²/4)h
d = 4 cm
h = 20 cm
Plugin the numbers and get V in cm³, then divide the given total volume of 28,134.4 cm³ by V. If the result is not an integer, then round down.
Add
20 + 4 = 24
Then
28,134.4 ÷ 24 = 1172.26
Rounded to the nearest 0.1 or the Tenths Place = 1,172.3
Therefore, 1,172.3 rods will be made per hour.
