The system of equations is solved using the linear combination method. What does 0 = −12 mean regarding the solution to the syst
inysia [295]
0=-12 is not true.

What this means is that there is no solution, and that the equation will always be false no matter the value of the variable.

Draw an area model that demonstrates that the quotient of 2080 and 40 is 52.
Scrat [10]

Area model is used to illustrate multiplication and division operations.

See attachment for the area model

The equation can be represented as:

\frac{2080}{40} = 52

Express 2080 as 1200 + 800 + 80

\frac{1200 + 800 + 80}{40}=52

Express as

\frac{1200 + 800 + 80}{40}=\frac{1200}{40} + \frac{800}{40} + \frac{80}{40}

Divide

\frac{1200 + 800 + 80}{40}= 30 + 20 + 2

See attachment for the area model

Write a proportion for 56% of a number is 244
Misha Larkins [42]
\frac{56}{100} =  \frac{244}{x} So, You cross multiply and get 56x=244(100). Simplify and you get 56x=24400. Divide each side by 56 and you get 435.71. 56% of about 435.71 is 244.
