Plz solve the equations for x. 1)ax+bx=13 2)ax+5=cx 3)ax+b=dx−1

Hello there!

ax + bx = 13

We want to start by factorizing out the variable x

x(a + b) = 13

Then divide both sides by a+b

x( a + b)/a + b = 13/a+b

x =

2)

ax + 5 = cx

Should start by adding -cx on both sides

ax + 5 - cx = cx - cx

ax + 5 - cx = 0

ax - cx = 0 - 5

ax - cx = -5

Then again, we need to factor out x because there's two of them

x( a - c) = -5

Then divide both sides by a-c

x(a - c)/ a - c = -5/a - c

x =

3)

ax + b = dx - 1

Start by adding -dx on both sides

ax + b - dx = dx - 1 - dx

ax - dx + b = -1

ax - dx = -1 - b

Here we go again, factor out x

x( a - d) = -b - 1

x =

I hope these answers help. As always, it is my pleasure to help students like you. Let me know if you have additional questions.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
