how do I solve −2(n− 9) + 4 using distributive property or combining like terms?
Answer:
Multiply the term outside of the parentheses by each term in the parentheses. To do this, you are essentially distributing the outer term into the inner terms. Multiply the term outside the parentheses by the first term in the parentheses. Then multiply it by the second term. If there are more than two terms, keep distributing the term until there are no terms left. Keep whatever operation (plus or minus) is in the parentheses
Step-by-step explanation:
in a school 46% of the 300 students are boys. how many girls are in the class than boy?
Answer:
138 of the students are boys, and 162 of them are girls. there are 24 more girls than boys.
Step-by-step explanation:
multiplying a number by its percent as a decimal gets you the percent of that number
300 x .46 = 138 boys
now subtract that from the original 300 to get the girls
300 - 138 = 162 girls
lastly subtract the girls from the boys to get how many more girls there are than boys
162 - 138 = 24

5 pencils and 3 pens costs £11.
4 pencils and 6 pens costs £16.
Find the cost of a pencil.
Find the cost of a pen.
Answer:
The pencil is £1 and the pen is £2
Step-by-step explanation:
Let the pencil be p and let the pen be f.
5p + 3f = 11
4p + 6f = 16
the top one multiplies by two:
10p + 6f = 22
4p + 6f = 16 subtract
6p = £6
pencil = £1
Then you substitute the value of the pencil into the equation and find the value of the pen.
Petra jogs 4 miles in 36 minutes. At this rate, how long would it take her to jog 10 miles.
Today, a bicycle rider rode her bike 5 1/2 miles to raise money for her school. Yesterday, she rode 6 1/4 miles her grandfather said he would give her 2$ for every mile she rode. How much money did she earn?
Answer:
.125 or 1/8
Step-by-step explanation:
The question is looking for the difference divided by the long ride. The long ride is 6 1/4 miles, so now we need to find the difference.
In order to do this, we take the larger distance and subtract the smaller distance.
We would take (Tip: Use decimals when you can. They are easier to work with ) 6.25 - 5.5 and we get .75 or 3/4 of a mile.
Now, we put .75 over 6.25 and simplify.
.125 or 1/8
Answer:
22$ simplified
Step-by-step explanation:
5*2=10+12=2*6
=22

Which sequence of rigid motions will definitely work to take triangle GHJ onto triangle STU?
A.) Rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.
B.) Translate GHJ by the directed in segment GS. Translate G’H'J by the directed line segment H'T. Translate G"H"J" by the directed line segment J"T.
C.) Translate GHJ by the directed line segment GS. Rotate G’H'J using S as the center by angle H'ST Reflect G"H"J" over ST.
D.) Translate GHJ by the directed line segment GT. Rotate G’H'J using T as the center by angle H'ST. Reflect G"H"J over ST.
The correct option is A. Rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.
There are four types of rigid motions that we will consider translation , rotation, reflection, and glide reflection.
Here we have to rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.
Hence option A is correct that is Rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.

Select one:
a. How many of you listen to music for an hour each day?
b. How many hours per week do you listen to music?
c. How many of you listen to music for more than an hour each day?
d. How many hours per week does the best musician listen to music?
Answer:
B
Step-by-step explanation:
You want to find the hours, not the number of people.

Ifp and q are non-zero rational numbers, and s and t are irrational numbers, select all of the statements that are always false.
The product pq is irrational.
The product pt is irrational.
The quotient
is irrational
0 The product st is irrational.
The quotient is rational.
Previous
Pause
Answer:
The product st is irrational.
The product pt is irrational.
Step-by-step explanation:
Let p = 3/4 and q= 5/9
Now multiplying these two non zero rational numbers
3/4 (5/9)= 15/36 ( this is also a rational number)
An irrational number is one which cannot be expressed in the form of p/q where p and q are integers( in the form of a simple expression) like the rational number.
Now let the two irrational numbers s and t be √3 and √5
Now multiplying the two irrational numbers we get
st = √3 √5
st =√15 ( this is also an irrational number)
√15 cannot be expressed in the form of a simple fraction.
Now multiplying pt
3/4 * √5= 3√5/4 ( this is also irrational)

Sonya made a resolution to walk 2.5 kilometers a day. On Tuesday she walked 4 times around the running track at the local high school (each lap is 0.4 kilometers.) How many additional kilometers does Sonya need to walk? (HINT: this is a multi-step problem with 2 operations...)
Answer:
0.9km
Step-by-step explanation:
Given that:
Sonya's resolution = walk 2.5 km daily
Total distance walked on Tuesday = 4 times around a running track
1 lap = 0.4 km
Hence, total distance by walking 4 times around track :
0.4km * 4 = 1.6km
Additional kilometers Sonya needs to walk:
2.5 - 1.6 = 0.9 km

How many planes pass through three or more vertices of a regular octahedron?
Answer:
The total number of planes = 23 planes
Step-by-step explanation:
The number of planes are give as follows;
The number of planes with three points, given that any three points of an octahedron forms a plane are ₆C₃ = 20
The number of distinct planes that has 4 points in the octahedron = 3
Therefore, the total number of planes are 20 + 3 = 23 planes.

Two siblings Edwin and Rhea are both going skiing but choose different payment plans. Edwin's plan charges $45 for rentals and $5.25 per lift up the mountain. Rhea's plan was a bundle where her entire day cost $108. Set up an inequality that models the number of trips, n, up the mountain for which Edwin will pay more than Rhea. Solve the inequality. Also, what is the greatest amount of trips that Edwin can take up the mountain and still pay less than Rhea? Explain how you arrived at your answer.
Answer:
n>12
Step-by-step explanation
45+5.25n>108
-45 -45
5.25n > 63
then divide both sides by 5.25
n>12

-8 + k = -17
What is k to make this equation true
Answer: The answer is k= -9
Step-by-step explanation:
this is how you solve it :
-8+k=-17
so then you add 8 to both sides so it would look like
-8+k+8=-17+8
then you simplify
after you simplify it would equal k=-9
