Container A holds x liters of water.
Container B holds 2391 liters of water more than container A, so container B holds x+2391 liters of water.
Container A and B hold 11875 liters of water altogether.

Container A holds 4742 liters of water.
It shows the teacher that U know the answer (like evidence) & U didn't just look it up or copy it.
Answer:
They will finish in time for Jamal to catch the bus.
Step-by-step explanation:
Jamal agreed to bring four dozen i.e. 48 cupcakes in for sale.
He started icing cupcakes at 7:40 a.m. at a rate of 3 cupcakes per minute up to 7:50 a.m. that is the time when he needs to be out of his house to catch his bus.
So, with in this 10 minutes (7:40 a.m. to 7:50 a.m.) he would be able to make (10 × 3) = 30 cupcakes.
Now, at 7:44 his older sister started icing cupcakes too. she iced them at a rate of 4 cupcakes per minute.
So, in this 6 minutes (7:44 a.m. to 7:50 a.m.) she will be able to make (4 × 6) = 24 cupcakes.
Therefore, in total Jamal will be able to made (30 + 24) = 54 cupcakes.
Since, 54 > 48 so, they will finish in time for Jamal to catch the bus. (Answer)
The diagram which the locus of all the points in the plane that are 3cm away from a single point A is Option B
<h3>What is a locus?</h3>
A locus is defined as a set of points, which satisfies a given condition or situation for a shape or a figure.
It is important to note that:
- The locus of points in a plane that are all the same distance from a single point is a circle with radius, r
- A circle is the locus of all the points in the plane which are equidistant from the points in that plane
- The locus of all points equidistant from the vertices of a square is a straight line that is perpendicular to the plane of the square, through the center of the square
We can see that for a circle, the locus of all points in the plane is the radius equidistant from that line.
Thus, the diagram which the locus of all the points in the plane that are 3cm away from a single point A is Option B
