5x+3y=18 and 3x-3y=15 solve for y and x using elimination method
Answer:
x = 4.125 or [tex]4\frac{1}{8}[/tex]
y = -0.875 or [tex]-\frac{7}{8}[/tex]
Step-by-step explanation:
5x + 3y = 18
3x - 3y = 15
3y and -3y can be cancled out becuase + and - cancel out and they both have 3y in them. We don't have to switch any signs in this case. You can just add them all exept 3y and -3y becuase they will be canceled out.
8x = 33
x = 4.125
Now we know what x is. We need to figure out what y is now. To figure out y chose an equation from the problem and plug in the x value. Lets chose 3x - 3y = 15.
3(4.125) - 3y = 15
12.375 - 3y = 15
-3y = 2.625
y = -0.875
Now we know what y is. I hope this helps :)
A cardboard box has a volume that is 6,336 cubic inches. A company creates a new design with the same proportions, but instead the dimensions are One-fourth the dimensions. Explain how you can find the volume of the new design without knowing the dimensions.
Answer:
Cube the scale factor 0.25. Then multiply the volume of the box by 0.015625.
Answer:
Since the dimensions have a proportional relationship, the new volume can be calculated using the original volume and the scale factor. The new volume will be the cube of the change, which is 1
64
. The new volume is the product of 6,336 and 1
64
.
Step-by-step explanation:
that is the sample answer.
The figure shows three quadrilaterals on a coordinate grid:
A coordinate grid is shown from positive 8 to negative 8 on the x axis and from positive 8 to negative 8 on the y axis. An image of a rectangle labeled E is shown on ordered pair negative 1, negative 1 and negative 3, negative 1 and negative 3, negative 2 and negative 1, negative 2. Another image of a rectangle labeled G is shown on ordered pair negative 2, negative 2 and negative 6, negative 2 and negative 6, negative 4 and negative 2, negative 4. Another image of a rectangle labeled F is shown on ordered pair negative 1, 1 and negative 1, 2, and negative 3, 2 and negative 3, 1.
Which of the following statements is true about the three quadrilaterals?
E and F are similar but not congruent.
E and G are similar but not congruent.
G and F are similar and also congruent.
E and G are similar and also congruent.
Answer:
E and G are similar but not congruent.
