What’s the correct answer?
nikdorinn [45]

Answer:

the triangle above is an isoceles triangle

therefore the base angles are equal

So we have:

X + X + 38= 180

2x = 180-38

2x = 142

X = 71°

There were two containers of oil. There was twice as much oil in the second container as in the first one. After using 13 liters
Iteru [2.4K]

Answer:

48 liters

Step-by-step explanation:

First container = x

Second container has twice as much oil.

Second container = 2x

13 liters of oil was used from first container.

x - 13

7 liters of oil was used from the second container.

2x - 7

Second container has 3 times more oil than the first one.

2x - 7 = 3(x - 13)

x - 7 = 3(x - 13)

x - 7 = 3x - 39

2x = 32

x = 16

First container = 16 liters

second container = 16 x 2 = 32 liters

Total = 16 + 32 = 48 liters

The graph shows two lines, A and B.
EastWind [94]

Answer:


Part A: one solution:

Part B: x = 3, y = 4.


Explanation:


1) Part A: how many solutions does the pair of equations for lines A and B have?


The solution of a system of equations in a graph is given by the intersetion of the curves that represent the equations.


In this case, there are two straight lines, which intersect in one and only one point.


Hence, the system has one solution.


2) Part B: what is the solution to the equations of lines A and B?


The solution is the pair of coordinates of the intersection point. It is (3, 4).


Therefore, the solution is x = 3, y = 4.
