u=-1

Step-by-step explanation:

if you replace with a or b the answer on the left side is actually bigger since it is closer to 0 than -20. same with choice d

choice c makes -12-28 which is a smaller value than -20

LLLLL.<br> indicated.<br> 18t + 11v = w - 13t, for t
In-s [12.5K]

Answer:

t=\frac{w-11v}{31}

Step-by-step explanation:

Given the equation with variables, t & v & w, we need to solve for t. So we take t to one side and all other things to another side and use basic algebra steps to solve for t. Shown below:

18t+11v=w-13t\\18t+13t=w-11v\\31t=w-11v\\t=\frac{w-11v}{31}

This is the expression for t [hence we solve for t].

What is the value of b. If A+B=C and A=35 and C=25 <br> Explain how you got this answer
Misha Larkins [42]

Answer:

B=-10

Step-by-step explanation:

Hi!

So let's write the equation again

A+B=C

The next step is to plug in known values:

35+B=25

Now we solve this as a normal algebra equation:

Do same to both sides

B = 25-35

B=-10

I hope this helped. Let me know if you have any questions

-25/J = 5<br> 16 + s = -90<br> 13 + t = 51<br> r/10 = (-6)<br> a + -12 =45
alexandr1967 [171]

we conclude that the solution for the given algebraic expressions are:

  • J = -5
  • s = -106
  • t = 38
  • r = -60
  • a = 57

<h3>How to solve these algebraic expressions?</h3>

Here we have some simple algebraic expressions:

The first one is:

-25/J = 5

We want to solve this for J.

Remember that we can perform the same operation in both sides of the equation, then we cans tart by multiplying both sides by J.

(-25/J)*J = 5*J

-25 = 5*J

Now we can divide both sides by 5, so we isolate J:

(-25)/5 = (5*J)/5

-5 = J

We conclude that the solution is J = -5.

Now, similarly for the other equations we have that:

16 + s = -90

Here we subtract 16 in both sides:

s = -90 - 16 = -106

13 + t = 51

Here we subtract 13 in both sides:

t = 51 - 13 = 38

r/10 = (-6)

Here we multiply both sides by 10:

r = (-6)*10 = -60

a + (-12) = 45

Here we add 12 in both sides:

a = 45 + 12 = 57

Then we conclude that the solution for the given algebraic expressions are:

  • J = -5
  • s = -106
  • t = 38
  • r = -60
  • a = 57
