Step-by-step explanation:

<u>Step 1: Define</u>

35 + 0.8x = 43 - 7x

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. [Addition Property of Equality] Add 7x on both sides:                                 35 + 7.8x = 43
  2. [Subtraction Property of Equality] Subtract 35 on both sides:                    7.8x = 8
  3. [Division Property of Equality] Divide 7.8 on both sides:                             x = 1.02564

1 3/7 plus 1 5/7 is how much in all
anyanavicka [17]
1 3/7 + 1 5/7 = 3 1/7

How to solve:

* Add whole numbers ( 1 + 1) and add numerators ( 3 + 5) Never add the denominators

*The answer will give you 2 8/7, but that's not write so I add 1 to 2 to make it 3 and make the numerator 1 so now the answer is 3 1/7

Urgent as i have final soon. How to solve problems like this f( ) = 8x+29​
Kaylis [27]

Answer:

See below

Step-by-step explanation:

we have f(x) = 8x + 29

essentially f(x) is a function and the number that goes in the blank is the input, whatever the input is you plug in to all values of x and evaluate to get the output

we are going to assume that we have to solve for f(4)

so we have f(4) = 8x + 29

because 4 is in the "input spot" we input a 4 for every x we see in the function

So we get f(4) = 8(4) + 29

we then simply evaluate

f(4) = 8(4) + 29

==> multiply 8 and 4

f(4) = 32 + 29

==> add 32 and 29

f(4) = 61

So if the input of f(x) was 4, the out put would be 61

Let me know if you have any further questions! :)
