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

Answer:

x = $\frac{1}{5}$ , y = 6

Step-by-step explanation:

5x + y = 7 → (1)

20x + 2 = y → (2)

Substitute y = 20x + 2 into (1)

5x + 20x + 2 = 7

25x + 2 = 7 ( subtract 2 from both sides )

25x = 5 ( divide both sides by 25 )

x = $\frac{5}{25}$ = $\frac{1}{5}$

Substitute this value into (2) and evaluate

20( $\frac{1}{5}$ ) + 2 = y

4 + 2 = y , so

y = 6

Answer:

Fourth option: 30 days

Step-by-step explanation:

We three path to complete the project:

Path A:

A1 → A2 → A3

10 days → 8 days → 9 days = 27 days

Path B:

B1 → B2 → B3

2 days → 7 days → 3 days = 12 days

Path C:

C1 → C2 → C3

10 days → 8 days → 12 days = 30 days

Then the duration of the critical path is 30 days, we can't conclude the project until each path has finished

What is the length of the longer side in this triangle

Elena L [17]

Did you notice the little box with corners marked in the angle down at the bottom ?
That angle is a right angle, and this triangle is a right triangle !

This piece of information is a big help. It breaks the problem wide open.
You know that in order to find the longest side of a right triangle . . .

-- Square the length of one short side.
-- Square the length of the other short side.
-- Add the two squares together.
-- Take the square root of the sum.

One short side=48. Its square = 2,304.
The other short side=48. Its square = 2,304.
Add the two squares: 2,304 + 2,304 = 4,608

The square root of the sum = √4,608 = 67.88 (rounded)
