When you divide both sides of an inequality by a negative number, you need to _____ the inequality symbol.
A. flip
B. eliminate
C. raise
D. multiply
Answer:
The correct option is option;
A. Flip
Step-by-step explanation:
When both sides of an inequality is divided by a negative number, it changes the sign of both numbers while their magnitude remain the same;
Therefore, if the right hand side of the inequality is lesser than the left hand side, when the signs of the left and right hand sides of the inequality changes after a division , by a negative number, we have;
The smaller right hand side of the inequality will then have a lesser negative magnitude than the left hand side of the inequality with a higher negative value and the left hand side (with the higher negative value) becomes lesser than the right and therefore, the symbol (sign) of the inequality is flipped
Therefore, when you divide both sides of an inequality by a negative number, you need to flip the inequality symbol.

Five quarts of a latex enamel paint will cover about 200 square feet of wall surface. How many quarts are needed to cover 215 square feet of kitchen wall and 65 square feet of bathroom wall?
Answer:
5.375 quarts
1.625
Step-by-step explanation:
determine amount of quarts of latex per square feet = 5/200 = 0.025
quart for 215 = 0.025 x 215 = 5.375 quarts
quart for 65 = 65 x 0.025= 1.625

There are expected to be 7 adults for every 3 children at the opening of a new museum. Find how many children are expected if there are 21 adults, 35 adults, and 56 adults.
Answer:
21 Adults= 7 Children , 35 Adults= 15 children and 56 Adults = 24 Children
Step-by-step explanation:
In other words, every 7 Adults creates a set of 3 Children
In the case of the 21 Adults, 21 /7 = 3sets of Children. Therefore 3x3 =9 Children.
For 35 adults, 35/7 gives us 5 sets
Therefore 5x3= 15 Children
Finally, 56 adults. 56/7= 8 sets
Therefore 8x3= 24 Children

3x + 12 = -3 What is the value of X
Answer:
x = -5
Step-by-step explanation:
i took algebra a couple years ago :)
Answer:
x=-5
Step-by-step explanation:
3x+12= -3
-12 -12
(subtract 12 from both sides because you want the variable by itself)
3x= -15
(divide by 3 so you can get x completely by itself)
x= -5 (final answer)

Ethan spent 12.5% of the money in his pocket on dinner. His dinner cost $15.25. How much did he have in his pocket? Group of answer choices $102.00 $172.36 $190.63 $122.00
Answer:
$122
Step-by-step explanation:
Let total money in his pocket = $ x
12.5% of x = $ 15.25
[tex]\frac{12.5}{100}*x= 15.25[/tex]
Multiply both sides by 100
12.5 *x = 15.25*100
125.5 *x = 1525
Divide both sides by 125.5
[tex]x = \frac{1525}{12.5}\\\\[/tex]
x = $ 122

1. Since 1963, the State of California has used the following rules for standard
car license plates
• Every license plate has the format ###AAA#, where # represents a numeral
0-9 and A represents a letter A-Z.
• The first and third letter positions cannot be I, O, or Q (to avoid
confusion with mumbers 1, 0).
How many license plates can the State of California issue that follow
these rules?
Answer:
137,540,000
Step-by-step explanation:
###AAA#
There are 10 digits from 0 to 9.
There are 26 letters from A to Z.
We apply the counting principle. We see the number of possible digits or letters than can be placed in each position, and then we multiply them together.
There are 10 digits for the first position.
###AAA#
10
There are 10 digits for the second position.
###AAA#
10 * 10
There are 10 digits for the third position.
###AAA#
10 * 10 * 10
There are 23 letters for the fourth position.
###AAA#
10 * 10 * 10 * 23
There are 26 letters for the fifth position.
###AAA#
10 * 10 * 10 * 23 * 26
There are 23 letters for the sixth position.
###AAA#
10 * 10 * 10 * 23 * 26 * 23
There are 10 digits for the seventh position.
###AAA#
10 * 10 * 10 * 23 * 26 * 23 * 10
Now we multiply all the numbers together.
10 * 10 * 10 * 23 * 26 * 23 * 10 = 137,540,000
A glass prism on a chandelier is 57 millimeters long. A base of the prism is an
equilateral triangle with side lengths of 8 millimeters and a height of about 5.2
millimeters. What is the approximate surface area of the prism?
Pleasee help!!
Answer:
1410 mm²Step-by-step explanation:
Given triangle prism with:
a = 8mm, h = 5.2 mm, l = 57 mmTotal surface area:
S = Pl + ah = 3al + ah = a(3l + h)S = 8(3*57 + 5.2) = 1409.6 mm² ≈ 1410 mm²Which shape has no parallel sides? (2 points)

a quadrilateral with sides of different lengths
a quadrilateral with single arrows going in the same direction for one pair of the opposite sides and double arrows for the other pair of opposite sides
Option (C) is the correct option.
What is quadrilateral?"In geometry, a quadrilateral is a four-sided polygon, having four edges (sides) and four corners (vertices). If the sides are represented by arrows, then the side is parallel to each other. A quadrilateral with sides of different lengths, may not have the sides parallel to each other".
For the given situation,
From the definition, a quadrilateral with sides of different lengths has no parallel sides.
Hence, option (C) is the correct option.
