Answer:
43.
Step-by-step explanation:
Follow PEMDAS (Parentheses, exponents, multiply, divide, add, subtract). First you do 8-4 which is 4, then you multiply 4 by 4 which is 16 since you multiply next, then you add 27 to 16 which then gets you to 43.
Joelle walked for 20 minutes and her speed was 3 miles per hour.
So
In 1 hour or 60 minutes Joelle walked for a distance of = 3 miles
Then
In 20 minutes Joelle walked for = (3/60) * 20 miles
= 60/60 miles
= 1 mile
Again
Joelle ran for 15 minutes at a speed of 6 miles per hour
So
In 1 hour or 60 minutes Joelle walked for a distance of = 6 miles
so
In 15 minutes Joelle walked for a distance of = (6/60) * 15 miles
= 15/10 miles
= 3/2 miles
So
The total distance covered by Joelle = 1 + (3/2) miles
= (5/2) miles
= 2 1/2 miles
So Joelle covered a total distance of 2 1/2 miles while walking and running.<span />
Multiples of four:
4, 8, 12, 16, 24, 28, 32, 36
Is 4 a factor of 48?
48/4=12
Yes, so that means 4 is not the answer.
Is 8 a factor of 48?
48/8=6
Yes, so that means 8 is not the answer.
Is 12 a factor of 48?
48/12=4
Yes, so that means 12 is not the answer.
Is 16 a factor of 48?
48/16=3
Yes, so that means 16 is not the answer.
Is 24 a factor of 48?
48/24=12
Yes, so that means 24 is not the answer.
Is 28 a factor of 48?
48/28= irrational number
No, so that means 28 is the answer.
Is 32 a factor of 48?
48/32= irrational number
No, so that means 32 is the answer.
Is 36 a factor of 48?
48/36= irrational number
No, so that means 36 is the answer.
Answer: 28, 32, 36

Step-by-step explanation:
6. Mr. Bernard travels 5.12 km per hour on his bike. How far can he travel in 3.25 hours?
Speed = 5.12km/hr
Time = 3.25 hr
To find the distance;
Distance = speed * time
Distance = 5.12 * 3.25
Distance = 16.64 km
7. Mrs. Allysa purchased 48 pencils at P 4.50 each. How much did she pay for all the pencils?
Quantity = 48 pencils
Cost price = P 4.50
To find the total selling price;
Total = quantity * cost price
Total = 48 * 4.50
Total = P 216
8. The Villaroel family bought a 125.65 square meter lot at P 4500.00 per square meter. How much did they
pay?
Quantity = 125.65 m²
Cost price = P 4500
Total price = 125.65 * 4500
Total price = P 565425
9. What is 2.7/10 = 0.27
10. What is 98.75/4 = 24.6875
11. A store owner has 63 kilograms of candy. If she puts the candy into 21 jars, how much candy will each jar
contain?
Mass = 63 kg
Amount = 21 jars
Each jar = 63/21 = 3 kg
12. Ratio: It is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
13. Proportion: It is a statement that two ratios are equal.
14. What ratio is equal to 3:5?
We would multiply both ratio by 2
3:5 * 2 = 6:10
15. What ratio is proportional to 4:6?
We would divide both ratio by 2
4:6 / 2 = 2:3
Answer:


Step-by-step explanation:
Solve the following equation:
-In order to solve a pair of equations by using substitution, you first need to solve one of the equations for one of variables and then you would substitute the result for that variable in the other equation:
-First equation:

-Second equation:

-Choose one of the two following equations, which I choose the first one, then you solve for
by isolating

-Subtract
to both sides:

-Subtract
to both sides:


-Divide both sides by
:


-Multiply
by
:


-Substitute
for
in the second equation, which is
:


Multiply
by
:


-Combine like terms:


-Subtract
to both sides:


-Multiply both sides by
:


-After you have the value of
, substitute for
onto this equation, which is
:


-Multiply
and
:


-Since both
and
have the same denominator, then add the numerators together. Also, after you have added both numerators together, reduce the fraction to the lowest term:
