Answer:

x=40/33

Step-by-step explanation:

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

25(4x−3)−2x=45−x

Step 1: Simplify both sides of the equation.

25(4x−3)−2x=45−x

(25)(4x)+(25)(−3)+−2x=45+−x(Distribute)

100x+−75+−2x=45+−x

(100x+−2x)+(−75)=−x+45(Combine Like Terms)

98x+−75=−x+45

98x−75=−x+45

Step 2: Add x to both sides.

98x−75+x=−x+45+x

99x−75=45

Step 3: Add 75 to both sides.

99x−75+75=45+75

99x=120

Step 4: Divide both sides by 99.

99x

120

Answer:

x=1.2121212121212....

Step-by-step explanation:

25(4x-3)-2x=45-x

+x +x

25(4x-3)-x=45

/25 /25

4x-3-(x/25)=1.8

(99x/25)-3=1.8

+3+3

99x/25=4.8

*25 *25

99x=120

/99 /99

x=1.2121212121212....

I have no idea what to do, help :’)

Ksenya-84 [330]

Answer:

x = 52

Step-by-step explanation:

I have included a chart to identify which angles are congruent (only alternate exterior/interior and corresponding). Basically if they are not alternate exterior/interior or corresponding, then they add up to = 180 degrees.

So since these angles are same side interior, they add up to = 180 degrees. We can write this as: A + B = 180

A + B = 180

2x + 76 = 180

2x = 104

x = 52

I hope this helps!

Beginning with the equation 2x + 8y = 12, write an additional equation that would create:

kramer

Answer:

[see below]

Step-by-step explanation:

A system of equations with no solution would show parallel lines. We just have make a equation that is parallel to the original equation.

The slope of 2x + 8y = 12 is $-\frac{1}{4}$ , and it's y-intercept is $\frac{3}{2}$ .

Since parallel lines have the same slope but not the same y-intercept, I would use $y=-\frac{1}{4}x+3$ .

Any equation that has -1/4 as the slope would work.

When graphed together, they show as a system with no solution.

Hope this helps.

At a graduation ceremony, some students earned bachelors in science degrees, some earned bachelors in arts degrees, and some stu

dedylja [7]

Answer:80students

Step-by-step explanation:

Using set notation concept,

n(U) be the total number of student = 200

n(AnS') be those that earned Bachelor in Art only= 120

n(A'nS) be those that earned Bachelor in Science only= 40

n(AnS) be students that earned both degrees.

Using the formulae below to calculate n(AnS) first;

n(AuS)=n(A'nS)+ n(AnS)+n(AnS')

200=40+n(AnS)+120

200=160+n(AnS)

n(AnS)=40

This shows that 40students earned bachelor in both degrees

Those that earned Bachelor in science degree will then be n(A'nS)+n(AnS) i.e 40+40 =80students.

NB: A' means complement of A(A not included)

'n' denote intersection and 'u' denote union.
