Answer:

C. 10.15

Step-by-step explanation:

If you left 8.25 and changed the minus sign to a addition sign and the -1.9 to just 1.9 and then add 8.25 + 1.9 together you will then get 10.15 a way to remember this is “leave, change, change,” you leave the first number and change the subtraction and negative number sign. :)

How do you solve -2 = t/3 - 11?

andrey2020 [161]

<h2><u>Answer:</u></h2><h2><u></u> $\boxed{t=27}$ <u></u></h2><h2><u></u></h2><h2><u>Solution Steps:</u></h2>

______________________________

<h3>1.) Multiply both sides of the equation by 3:</h3>

$\frac{t}{3}$ × $3=t$

$-11$ × $-3=-33$

<em> - We do this because we need to get x alone and separate from fraction from. </em>

<u>Equation at the end of Step 1:</u>

<u /> $-6=t-33$ <u />

<h3>2.) Add 33 to both sides:</h3>

$-33+33=$ Cancels Out

$-6+33=27$

<em> - We do this to cancel out an extra numbers in order to get only x alone with 1 number on the opposite side of the equal. </em>

svetoff [14.1K]

Your answer is to the question 16,4
<span>Form of the equation: y = mx + b
---
You are given that y = 8 when x = 7.
And you are given that m = -1.2
-----
Substitute for those letters and solve for "b"::
8 = -1.2*7 + b
8 = -8.4 + b
b = 8 + 8.4 = 16.4</span>
