On a vocabulary list within a study guide, definitions should be written
Lana71 [14]

Solution:

In a vocabulary list ,within a study guide, if we are defining something

It should never be written in abbreviated form because some words are difficult to understand in abbreviated form and chances of getting confused are higher while reading.

It is better if we start writing Definition in

Arranging in alphabetical order and then writing in complete sentences.

But writing in complete sentences of any vocabulary must be first priority.

Option (C) In complete Sentences

7-2(2+3x)=27what is he answer
Taya2010 [7]
<span>Simplifying 7 + -2(2 + 3x) = 27 7 + (2 * -2 + 3x * -2) = 27 7 + (-4 + -6x) = 27 Combine like terms: 7 + -4 = 3 3 + -6x = 27 Solving 3 + -6x = 27 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -6x = 27 + -3 Combine like terms: 3 + -3 = 0 0 + -6x = 27 + -3 -6x = 27 + -3 Combine like terms: 27 + -3 = 24 -6x = 24 Divide each side by '-6'. x = -4 Simplifying x = -4</span>

Monica has been saving her spare change. So far she has saved 40 coins for a total of $6.25. Some of the coins are quarters (25
neonofarm [45]

Answer:

10 quarters

40 dimes

Step-by-step explanation:

q + d = 40

25q + 10d = 625

25 > 10

q < d

25(10) = 250

10(40) = 400

$2.50 + $4.00 = $6.00

The height of a triangle is 7 cm longer than its base.
katrin [286]
A) Height -7 = base
B) .5 * height * base = 60
Substituting A into B
B) .5 * height * (height -7) = 60
B)  .5*height^2  -3.5*height = 60
B)  .5*height^2 -3.5*height -60 = 0
Using the quadratic formula:
Height = 15
Subtracting 7 gives us the base length
Base = 8
**************************************************************
Double-Check
.5 * 15 * 8 = 60

Find the measures of ∠B and ∠C. PLEASE HELP!!
BartSMP [9]

It's an isosceles triangle, therefore m∠B = m∠C.

We have the equation:

2x + 10 = 3x - 5      <em>subtract 10 from both sides</em>

2x = 3x - 15     <em>subtract 3x from both sides</em>

-x = -15     <em>change the signs</em>

x = 15

m∠B = (2x + 10)°

m∠B = (2 · 15 + 10)° = (30 + 10)° = 40°

We know, the sum of measures of a tringle is equal 180°.

m∠A + m∠B + m∠C = 180°

m∠B = m∠C = 40°

<h3>Answer: ∠B = 40° and ∠C = 40°</h3>
