The students in Roberto's school are painting a mural that will be 15 feet by 8 feet. First they make a scale drawing of the mur

bixtya [17]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

In point A:

The two-point C and y is given, where C is the scale drawing lengths and y is the actual mural lengths so, the formed equation is:

$\to \frac{c}{y}=\frac{2}{5}$

In point C :

Using the value of the scale:

let 1 feet: 20 feet

therefore the equation is:

$\to \frac{c}{y}=\frac{1}{20}$

The size of c will be the length of:

$\to c= \frac{y}{20}\\\\\to c= \frac{8}{20}\\\\\to c= 0.4\\$

The diagram c scale width will be:

$\to c= \frac{y}{20}\\\\\to c= \frac{15}{20}\\\\\to c= 0.75\\$

How to solve -66.17738=6.618(4.3x+1.1)-7.1(x-6.8) have not done algebra in 30 years and cannot help my son with this problem

fenix001 [56]

Let's solve your equation step-by-step.

−66.17738=6.618(4.3x+1.1)−7.1(x−6.8)

Step 1: Simplify both sides of the equation.

−66.17738=6.618(4.3x+1.1)−7.1(x−6.8)

−66.17738=(6.618)(4.3x)+(6.618)(1.1)+(−7.1)(x)+(−7.1)(−6.8)(Distribute)

−66.17738=28.4574x+7.2798+−7.1x+48.28

−66.17738=(28.4574x+−7.1x)+(7.2798+48.28)(Combine Like Terms)

−66.17738=21.3574x+55.5598

Step 2: Flip the equation.

21.3574x+55.5598=−66.17738

Step 3: Subtract 55.5598 from both sides.

21.3574x+55.5598−55.5598=−66.17738−55.5598

21.3574x=−121.73718

Step 4: Divide both sides by 21.3574.

21.3574x

21.3574

−121.73718

21.3574

x=−5.7
