8x - 10 = 86 {combined like terms}
8x = 96 {added 10 to both sides}
x = 12 {divided both sides by 8}
3x - 5 = 31 {substituted 12, in for x, into 3x - 5}
width = 12 in.
length = 31 in.
Answer:
85%*x =51
Step-by-step explanation:
of means multiply
Hence,
85% times x =51
Hi Andrewkayman01pelzjin,
To find the answer to this question we need to add and subtract. So, $83 + $1200= $1283. So now, we need to subtract $896 and $272 from $1283 to get $1283 - $896 = $387 then, $387 - $272 = $115. Now, add $115 ($115 + $115 = $230) to get $230.
Your Answer Is: $230
Hope This Helps!

Well all you need to do to write the linear equation for this function. I assume you want to know, is that you must obtain 2 points, and calculate the slope, then place the info within the following form.
Y = mx + b
1 of the points has to be the y intercept, which can be obtained from the graph, and the other, any other point, which can also be the X intercept.
So, X intercept - (2,0)
Y intercept - (0,3).
Slope = y/X = 3-0/0-2
Slope = 3/-2 or -3/2.
Now put everything together in form:
Y = mx + b
Y = -3/2x + 3.
I believe this is the solution.
Let's go through this problem step by step while bearing in mind the concept of
PEMDAS.
Step 1:

Declaration of the expression. Nothing wrong here yet.
Step 2:

Clarise evaluated what's inside the parenthesis first - which was the right thing to do! There are no mistakes in this step.
Step 3:

In this step she subtracted first. This should not be the case! PEMDAS tells us that the exponents and division gets higher priority than subtraction. This is therefore the first mistake Clarise makes.
Step 4:

In this step Clarise evaluates the exponent. This does not violate any rules (relative to the previous expression) since PEMDAS tells us that exponents take higher priority than division.
Step 5:

(Clarise's final answer)
In Clarise's final step, she manages to get the wrong answer! Dividing 51.68 by 0.16 would give us 323. This is another mistake of Clarise.
Looking at the choices, we can now identify what mistakes Clarise made:
-She subtracted before evaluating the exponents
-She subtracted before she divided
-She divided incorrectly
