The two numbers would be 28 and 16 respectively.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have the ratio of Jenny’s trophies to Meredith’s trophies is 7 : 4. The difference between the numbers is 12.
From the question, we can write -
7x - 4x = 12
3x = 12
x = 4
The numbers would be -
[a] = 7x = 28
[b] = 4x = 16
Therefore, the two numbers would be 28 and 16 respectively.

Tell whether the ratios form a proportion.
1 to 0.4 and 9 to 3.6
Answer:
no? cause one is negative and the other is positive and I'm guessing they both have to be the same
Step-by-step explanation:
3 = x
x 3
These are fractions btw
Cross multiply:
3 * 3 = x * x
Simplifying
3 * 3 = x * x
Multiply 3 * 3
9 = x * x
Multiply x * x
9 = x2
Solving
9 = x2
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1x2' to each side of the equation.
9 + -1x2 = x2 + -1x2
Combine like terms: x2 + -1x2 = 0
9 + -1x2 = 0
Add '-9' to each side of the equation.
9 + -9 + -1x2 = 0 + -9
Combine like terms: 9 + -9 = 0
0 + -1x2 = 0 + -9
-1x2 = 0 + -9
Combine like terms: 0 + -9 = -9
-1x2 = -9
Divide each side by '-1'.
x2 = 9
Simplifying
x2 = 9
Take the square root of each side:
x = {-3, 3}

Math problem:
43 ÷ (7 − 3) × 2.
Answer: 21.5
Step-by-step explanation:
Answer:
21.50
Step-by-step explanation:
43 ÷ (7 − 3) × 2
According to order of operations you would do 7 - 3 first which gets you to 4.
43 ÷ 4 × 2
Now you would do 43 ÷ 4 which is 10.75 so next...
10.75 × 2
You should get an answer of 21.50
Hope this helps :D

Answer:
The answer is that the student plotted each (x,y) point as (y,x)
Step-by-step explanation:
If you look at the graph, you will notice that points aren't correct. The first point (200,207), the point is plotted as (207,200). The numbers are switched. The point is at 200 on the y axis and at 207 on the x axis, which is reversed from what the point should be.
Determine and prove which lines are
parallel
I’ll give Brainliest. Due Soon.
Answer:
a and b are parallel, and so are t and s.
Step-by-step explanation:
By U-angles, a and b are parallel, because 108 + 72 = 180 degrees.
By corresponding angles and F-angles, t and s are parallel, because 108 = 108 degrees.
