Step-by-step explanation:
Given
5x + 7 < - 23
Subtracting 7 from both sides
5x + 7 - 7 < - 23 - 7
5x < - 30
Dividing both sides by 5
5x / 5 < - 30 / 5
x < - 6
Hope it will help :)
Answer: x = 14/5
Step-by-step explanation:
1. Add 7 to both sides.
5x=7 +7
5x=7+7
Simplify 7 +7 to 14
5x = 14
5x=14
Divide both sides by 5
x =14/5
x = 14/5

The table gives the probabilities that orphaned pets in animal shelters in six cities are one of the types listed. The probability that a randomly selected orphan pet in an animal shelter in Austin is a dog is _____ %. The probability that a randomly selected orphaned dog in the same animal shelter in Austin is a Chihuahua is _____ %. (Round to the nearest hundredth.)
For all the dogs: you have 2.65+2.46+3.67+2.91 = 11.69%
Now, the probability of getting a chihuahua would be 3.44/11.69=0.2942= 24.92
Step-by-step explanation:
there ya go!!
Answer:
The probability that a randomly selected orphan pet in an animal shelter in Austin is a dog is 11.71% .
The probability that a randomly selected orphaned dog in the same animal shelter in Austin is a Chihuahua is 29.37% .
Step-by-step explanation:
2.76% + 2.86% + 3.44% + 2.65% = 11.71%
11.71 / 3.44 = .2937
.2937 = 29.37%
Amelia invests money in an account paying simple interest. She invests $180
and no money is added or removed from the investment. After one year, she
has $187.20. What is the simple percent interest per year?
Answer:
4%
Step-by-step explanation:
100% represents the starting balance: $180.
Method 1
Express the ending balance as a percentage of the starting balance:
$180
1.04
1.04 times 100=
1.04×100=
104%
Subtract the starting 100% to get the percent interest:
4%
Method 2
$187.20−$180=
$7.20
$180
$7.20
0.04
0.04 times 100=
0.04×100=
4%

The interior angle sum of a convex polygon is 2.520 How many sides does the polygon
have?
Complete Question
The interior angle sum of a convex polygon is 2520.How many sides does the polygon have?
Answer:
16 sides
Step-by-step explanation:
The sum of angles in a polygon formula is given as:
(n - 2)180°
Where n = Number of sides of the polygon
Hence:
(n - 2)180°= 2520°
Divide both side by 180°
(n -2) = 2520/180
n - 2 = 14
n = 14 + 2 = 16
Therefore the number of sides the convex polygon has 16 sides.

Answer:
z = 24
Step-by-step explanation:
35/30 = 7/6
28/7 = 4
6 x 4 = 24
28/24 = 7/6
Answer:
x = 24
Step-by-step explanation:
All you have to do is cross multiply like this..
30 x 28 = 35 x X
=
x = 30 x 28/35
30 x 28 = 840 / 35 =
24
So x is equal to 24

Q2: How do you use the distance formula and slope formula to classify quadrilaterals
Answer:Distance formula and the slope formula can be used to classify a quadrilateral as using the slope formula, the slopes can tell what angles it have or if lines are perpendicular or not.
Distance formula can be used to find the length of the sides and it also tells that whether it is right triangle or isosceles or an equilateral triangle.

The owner of a tree service has a chainsaw that uses a mixture of 200 ounces of gasoline and 2 ounces of oil. The owner needs to make at least
5 gallons of the oil-gasoline mixture.
If the owner knows that l gallon is equal to 128 fluid ounces, which inequality can be used to determine the amount of oil needed?
Answer:
You need 6oz (or 6.3366oz) of oil for the 5 gallon mixture.
Step-by-step explanation:
First, write down the essentials of this word problem.
The chainsaw uses 200 ounces gasoline (or gas) and 2 ounces oil.
The owner needs 5 gallons (640 ounces) of the mixture.
The chainsaw uses a 202 ounce mixture (200oz gasoline 2oz oil).
The mixture is 0.0099 repeating % oil and 0.9900 repeating % gasoline.
0.0099 (oil) x 640 (final mixture) = 6.3366oz repeating oil needed.
0.9900 (gas) x 640 (final mixture) = 633.6633 repeating gas needed.
This means you need 6.3366oz or 6oz (rounded) for the 5 gallon mixture.
CHECKING WORK:
6.3366 + 633.6633 = 639.99999997
OR ROUNDED:
6 + 634 = 640

£25 = 700 rubles, how many £ are in 1,260 rubles?
£
Answer:
45
Step-by-step explanation:
25 = 700
Y = 1260
Now you need to do cross multiplication .
25 X 1260=700Y
Since it's in a multiplying form you can simplify by dividing 700 by 25
1260=700Y/25
1260=28Y
Y=45

(3ax + 4a) - (9x + 15a)
Answer:
3ax−11a−9x
Step-by-step explanation:
3ax+4a−(9x+15a)
Distribute the Negative Sign:
=3ax+4a+−1(9x+15a)
=3ax+4a+−1(9x)+−1(15a)
=3ax+4a+−9x+−15a
Combine Like Terms:
=3ax+4a+−9x+−15a
=(3ax)+(4a+−15a)+(−9x)
=3ax+−11a+−9x

Answer:
39 units
Step-by-step explanation:
The angle markings tell you this is an equilateral triangle, so all sides are the same length.
10x -11 = 2x +29
8x = 40
x = 5
Then the side length is ...
2x +29 = 2·5 +29 = 39
The length of side KL is 39 units.

Step-by-step explanation:
Grace earned £27,000 last year.
She worked for 32.5 hours a week for 46 weeks.
Calculate her pay per hour.
Give your answer to 2 decimal places.
Answer:
£18.06
Step-by-step explanation:
The computation of her pay per hour is shown below:
= Total earnings last year ÷ Total number of hours she worked
= £27,000 ÷ (32.5 hours × 46 weeks)
= £27,000 ÷ 1,495 hours
= £18.06

if $45 is divided into the ratio 4:5 the smaller part is A. $1.50 B.$3.50 C.$4.50 D.$24.50 Asap
Answer:
Step-by-step explanation:
When you do 45 divided by 9 you get 5.
45 / 9 = 5
To figure out what the smaller number (in this the 4) equals,
you have to do 4 times 9 to get 36.
4 * 9 = 36
So your answer is 36.
