Answer:
1/8
Step-by-step explanation:
To make any decimal into a fraction, it will need to be over 1. 0.125 needs to be put over 1.
= 0.125 / 1
Multiply the fraction by 8/8 to turn 0.125 into a whole number.
= 1 / 8

What is X equal to? It’s not 180 -.-
Answer:
x = 163
Step-by-step explanation:
(x-5)+22= 180
x = 143
hope this helps!!!
Answer:
x = 163
Step-by-step explanation:
It is 180 and there is no doubt in it. a straight line always measures 180 and this is a straight line not even curved
to find the value of x
x - 5 + 22 = 180
x + 17 = 180
x = 180 - 17
x = 163
we can even cross check
163 - 5 + 22
158 + 22
= 180
if the line wasn't 180 I wouldn't able to cross- check

Step-by-step explanation:
A clothing store is having a sale on shoes of 40% off the original price. They have not marked the new price on any of the shoes. Write an equation that you could use to determine the price of a pair of shoes sold by the store if you know the original price. Use x to represent the original sale price and y to represent the sale price.
Answer:
x * 0.60 = y
Step-by-step explanation:
0.60 because 100% - 40% =60% 60%=0.60

What is 80% of 60? Help meeeee
Answer:
48
Step-by-step explanation:
Divide 60 by 100 to get 1% of 60.
0.6
Multiply 0.6 by 80 to get 80%
48
48 is 80% of 60.
Step-by-step explanation:
What is 80% of 60?
To get the answer,
First, convert the percentage to decimal form. How? Change the percent sign to decimal point. Then, move the decimal point two (2) places towards the left side of 80. It looks like this:
[tex]80 / 80.[/tex]
[tex]80. 80[/tex] decimal point moves two places to the left
Therefore, 80% is equal to 80 .
Then, let's solve!
Multiply 60 by 0.80 to get the answer.
60x0.80=48
From here, we get to know that the 80% of 60 is 48.

HCF and LCM questions
Responses:
6. (i) 27
(ii) 4 rose stalks, 3 lily stalks, and 2 orchid stalks
7. After 18 minutes
8. (i) May 7th
(ii) Every 12 days
How can the HCF and LCM be used to find the right responses?6. The number of stalks of roses = 108
Number of stalks of lilies = 81
Number of stalks of orchids = 54
(i) The largest number of baskets that can be packed is given by the
Highest Common Factor, GCF , or HCF, of 108, 81, and 54, which is
found as follows;
54 = 2 × 27
81 = 3 × 27
108 = 4 × 27
Therefore;
The HCF of 108, 81, and 54 is 27
Which gives;
The largest number of baskets that can be packed = 27(ii) From the above factors, we have;
Number of rose stalks per basket = 4Number of lilies per basket = 3Number of orchids per basket = 27. Length of the circular path = 1 km. = 1,000 m.
Time Lixin takes to walk one round = 18 minutes = 1,080 seconds
Time Khairul takes to run one round = 360 seconds
Time Devi takes to cycle 2 rounds = 4 minutes
Therefore;
Time Devi takes to complete 1 round = [tex]\frac{4}{2}[/tex] = 2 minutes = 120 seconds
Required:
The time at which the three of them will next meet at the starting point
Solution:
The time at which they meet at the starting point is given as the lowest
common multiple, LCM of 1,080, 360, and 120, which is given as
follows.
1,080 = 360 × 3
1,080 = 120 × 9
1,080 = 1,080 × 1
Therefore;
The LCM of 1,080, 360, and 120 is 1,080
The time they will next meet at the starting point is after 1,080 seconds which is 18 minutes8. The days off of Nora = Every 4 days
Days off for Amirah = Every 6 days
Nora's last day of = 29 April
Amirah's last day off = 1 May
(i) The next time they will both have the same day off is given as follows;
6·x = 2 + 4·x
2·x = 2
x = 1
Therefore, the next time Amirah has a day off, which is 1 May + 6 days = 7 May, they will both have the same day off.
They will both have the same day off on May 7(ii) The number of days that it will take for them to have the same day off is given by the HCF of 4 and 6, which is every 12 days.

(ii) Give a reason for your answer.
b) (i) Write down the value of y.
(ii) Give a reason for your answer.
c) Work out the size of angle z.
Answer:
see explanation
Step-by-step explanation:
x = 65° ( vertically opposite angles )
y = 71° ( alternate angles )
The sum of the 3 angles in a triangle = 180° , then
x + y + z = 180° , that is
65° + 71° + z = 180°
136° + z = 180° ( subtract 136° from both sides )
z = 44°
So x = 65°, y = 71° , z = 44°
what is -7+4m+10=15-2m=
Answer:
m=2
Step-by-step explanation:
Add the numbers
-7+4m+10=15-2m
3+4m=15-2m
Rearrange terms
3+4m=15-2m
4m+3=15-2m
Rearrange terms
4m+3=15-2m
4m+3=-2m+15
Subtract 3 from both sides of the equation
4m+3=-2m+15
4m+3-3=-2m+15-3
Simplify
4m=-2m+12
Add 2m to both sides of the equation
4m=-2m+12
4m+2m=-2m+12+2m
Simplify
6m=12
Divide both sides of the equation by the same term
6m = 12
6m/6 = 12/6
Simplify
m = 2
