Answer:

145°

Step-by-step explanation:

x°+70°=(2x-5)°

x°+70°=2x°-5°

70°+5°=2x°-x°

75°=x°

x=75

JKM=(2x-5)°

=(2x75-5)°

=(150-5)°

=145°

VARVARA [1.3K]
The group of seventh graders will have 5 groups of five: 5 is the greatest multiple of 25, or 5*5=25.

Given the trinomial 2x2 + 4x + 4, predict the type of solutions.
rodikova [14]
Trinomial 2x² + 4x + 4.

It's of the form ax²+bx+c and it's discriminant is Δ=b² - 4.a.c 

(in our case Δ = 4² - (4)(2)(4) → Δ = - 32

We know that: x' = -1 + i     and x" = -1 - i

If Δ > 0 we have 2 rational solutions x' and x"

If Δ = 0 we have1 rational solution x' = x"

If Δ < 0 we have 2 complex solutions x' and x", that are conjugate

In our example we have Δ = - 16 then <0 so we have 2 complex solutions

That are x'= [-b+√Δ]/2.a      and x" = [-b-√Δ]/2.a

x' =

A + 5 = -5a + 5 what does x equal
antoniya [11.8K]

Answer:

a = 0

Step-by-step explanation:

a + 5 = -5a + 5      subtract 5 from both sides

a + 5 - 5 = -5a + 5 - 5

a = -5a                add 5a to both sides

a + 5a = -5a + 5a

6a = 0                 divide both sides by 6

6a / 6  =  0 / 6

therefore,

a = 0

What is the solution to -2(3x - 9) + 5x = -10?
sweet-ann [11.9K]
-2(3x - 9) + 5x = -10
-6x + 18 + 5x = -10
-6x + 5x = -10 - 18
-x = -28
x = 28 <===
