Make x the subject of the formula х +b= a

Mathematics
1 answer:
blagie [28]3 years ago
5 0

Answer:

x = a(c - b)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

x/a + b = c

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

  1. Subtract <em>b</em> on both sides:                    x/a = c - b
  2. Multiply <em>a</em> on both sides:                     x = a(c - b)

Ted is saving for a toy. He has no money now, but
sweet-ann [11.9K]

Answer:

4D - 1

Step-by-step explanation:

So, if Ted saves $D for 4 weeks, then this amount will be equal to 4D because multiplication is simply repeated addition. We can imagine this situation as D+D+D+D, for the 4 weeks he is saving. We can simplify this to 4D in the expression.

Next, the question tells us that this will be 1 dollar more than needed. So, if we want to find the cost, we need to subtract that dollar.

Thus, the final expression is 4D - 1 because this represents 1 dollar less than the money he saves for 4 weeks.

I'm not sure if this is right or not could someone also explain why ?
nikitadnepr [17]
The mapping rule for 90 degrees counterclockwise would be (-y,x). So if you had (x,y) it would transfer to (-y,x). Yours is wrong it should be (4,-3). Remember
-(-4) is 4 and -3 stays as -3.

Basically, memorize these mapping rules.

Hope this helped!

Find the tangent of both angle A and angle B. Ignore what the picture says the numbers are the same.
Elena-2011 [213]
For the angle A we have:
 tan (A) = C.O / C.A
 tan (A) = 10/24
 Simplifying we have:
 tan (A) = 5/12
 For angle B we have:
 tan (B) = C.O / C.A
 tan (B) = 24/10
 Simplifying we have:
 tan (B) = 12/5
 Answer:
 
The tangent of angles A and B is given by:
 
tan (A) = 5/12
 
tan (B) = 12/5
