Step 3: Check 2

Substitute:                    -5 + 3(1) > -8Multiply:                        -5 + 3 > 8Add:                              -2 > -8Check:                          -2 > -8 ? Yes

Step 4: Check 3

Substitute:                    -16 + 3(2) > -8Multiply:                        -16 + 6 > -8Add:                              -10 > -8Check:                          -10 > -8 ? No

Step 5: Check 4

Substitute:                    -1 + 3(-2) > -8Multiply:                        -1 - 6 > -8Subtract:                       -7 > -8Check:                           -7 > -8 ? Yes

Step 6: Check 5

-9=2(18)+9y how do you work it out

Answers

Answer:

y = -5

General Formulas and Concepts:

Pre-Alg

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

-9 = 2(18) + 9y

Step 2: Solve for y

Multiply:                                   -9 = 36 + 9ySubtract 36 on both sides:     -45 = 9yDivide both sides by 9:           -5 = yRewrite:                                     y = -5

Step 3: Check

Plug in y to verify it's a solution.

Substitute:                    -9 = 2(18) + 9(-5)Multiply:                        -9 = 36 - 45Subtract:                       -9 = -9

Which angles form a linear pair?

Answers

Answer:

A common arm

A common vertex

Their interiors do not overlap

The sum of two angles is 180°.

Therefore, linear pair of angles are adjacent angles whose non-common arms are opposite rays.

Explanation: A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

QB = PC (Since ABC is isosceles triangle and PB = QC) (S)

Topic: congruence and similarity

If you like to venture further, do check out my insta (learntionary) where I constantly post math tips! Thanks!

Answer:

SAS criteria

Step-by-step explanation:

Given is isosceles triangle as AB = AC, it means angles B and C measure same

Triangles PBC and QCB have common side BC, equal sides PB = QC as PB = AB - AP and QC = AC - AQ

So two sides and the angle between are congruent:

BC ≅ BC, PB ≅ QC, ∠PBC ≅ ∠QCBSo ΔPBC≅ΔQCB as per SAS criteria

A student can type

hour. How many pages can the student type in an hour?

Answers

10/3 or 3 1/3 pages

Answer:

A student can type 3.33 pages in 1 hour.

Step-by-step explanation:

(Assuming you mean 2/3 of a page and 1/5 of an hour)

To solve this we need to multiply both sides by 5. This is because when you multiply 1/5 by 5 you get 1 hour and what you do to one side you must do to the other.

1/5 * 5 = 1

2/3 * 5 = 3.3333

Rounding to the nearest hundredth:

3.33

A student can type 3.33 pages in 1 hour.

Answer:

  P = 250 +50t

Step-by-step explanation:

We are given two pairs of time and price:

  (t, P) = (0, 250)  and  (5, 500)

We can put these into the 2-point form of the equation for a line:

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  P = (500 -250)/(5 -0)(t -0) +250

  P = 250/5t +250

  P = 50t +250 . . . . Madelyin's cost equation

Answer:

[tex]B=\frac{2A}{h}-b[/tex]

Step-by-step explanation:

To solve this B needs to be isolated. First we must multiply both sides of the equation by 2 to get rid of the fraction on the left side. Next, divide both sides by h to get rid of the h on the left side. Finally, subtract b form both sides to get B by itself.

your answer would be b=2a/h-B
