Answer:
x=2
Step-by-step explanation:
-2x-3=4x-15
add 2x to each side
-3=6x-15
add 15 to each side
12=6x
divide each side by 6 to get x alone
2=x

Xin recorded the grade-level and instrument of everyone in the middle school School of Rock below.
Answer:
13/35
Step-by-step explanation:
Probability determines the likelihood of an event happening.
Since we are not looking at the 7th Graders list, let's focus on the list on 8th Graders.
Given:
8th gradeGuitar - 4 students
Bass - 13 students
Drums - 13 students
Keyboard - 5 students
Since we are trying to find the probability of an eighth grader chosen at random to play the drums, let's turn our attention to how many students actually play the drums.
13 students play the drums.
In order to find the probability of a student chosen at random who plays the drums, we have to find how many students play the drums (which we already found) out of the total amount of students there are in that grade/section. Summing up, probability = the amount of favorable cases divided by the amount of possible cases.
Let's use this formula:
P(A) = n/N
Where "P(A)" stands for the probability of the event "A". And "n" represents the # of favorable outcomes and "N" represents the # of total possible outcomes.
Let's find how many students are in 8th grade now by adding all the people who play the musical instruments together:
4 + 13 + 13 + 5
= 35 possible outcomes.
Now let's plug it into the formula:
P(A) = n/N
P(A) = 13/35
13/35 can simplify any further.
The probability of choosing a student who plays the drums at random is 13/35.
Base your answer to the following question on the following maps and your knowledge of civics:
Two maps of the presidential election results from 2008 are shown. One map shows results by county. The land area of counties won by Republicans is greater than the land area of counties won by Democrats. Another map of Presidential election results by state. Approximately half of the states show Democrat winner, and the other half show a Republican winner. Red areas are focused on center of country.

Interpreting the presidential election using the map descriptionFrom the question, we have the following parameters that can be used in our computation:
Description by county:
Land areas won by Republicans is greater than those won by Democrats.
Description by state:
Democrat winner = approximately half
Republican winner = approximately half
The above means that
The republican won the election
This is because;
When calculated by states, they have the same proportionWhen calculated by county, Republican hold more votesHence. The Republicans won the most electoral votes in the election.

Answer:
The answer is The Democrats won the most electoral votes in the election.
The map showing the results by county shows that the Republicans won more land area, but the map showing the results by state shows that the Democrats won more states. The electoral college is made up of electors from each state, and the number of electors each state has is equal to the number of seats it has in Congress plus its two senators. The Democrats won more states in 2008, so they won more electoral votes and the election.

James has a set of five solar planets and Ben has a set of six smaller solar planets each set of planets produce the same amount of energy at 3 of games is planets are produced are on and producing energy for events are on and producing energy whose solar planets are producing more energy explain
Answer:
bens
Step-by-step explanation:
Step-by-step explanation:
If E is the amount of energy that each full set of panels produces, then ...
3 of james's 5 panels produce 3/5E
4 of Ben's 6 panels produce 4/6E
We can compare these fractions when they have a common denominator.
3/5E = 18/30E . . . . energy from James's panels
4/6E = 20/30E . . . energy from Ben's panels
18/30 < 20/30 . . . . so Ben's panels are producing more energy

What is the surface area of the square pyramid? This includes the square base.
ASAP! answer question down below please and thank you!
Answer:
105 square inches
Step-by-step explanation:
area of a triangle = 1/2( base * height)
The base is 5 and the height is 8.
= 1/2 ( 5 *8)
= 1/2(40)
= 20
The area of each triangle = 20 sq inches
So 4 triangles x 20 sq inches each = 80 sq inches.
The area of the square is 5 x 5 = 25 sq inches.
Add them together.
80 + 25 = 105 square inches

in a game, if you roll a 1 on a 6-sided number cube, you lose a turn.
(a) What is the probability that you roll a 1? Explain your reasoning.
(b) What is the probability that you either roll a 1 or do not roll a one? Explain your reasoning.
(c) What is the probability that you don't roll a 1? Explain your reasoning.
Answer:
Answer:
(a) The probability of rolling a 1 on a 6-sided number cube is
1/6
. This is because there is 1 outcome that results in a 1 (rolling a 1) and there are 6 total possible outcomes.
(b) The probability that you either roll a 1 or do not roll a 1 is 1. This is because there are no other possible outcomes. You either roll a 1 or you don't.
(c) The probability that you don't roll a 1 is 6/5
. This is because there are 5 outcomes that do not result in a 1 (rolling a 2, 3, 4, 5, or 6) and there are 6 total possible outcomes.

find the area of the shape below
it is year 7 work can someone help i'll give em 50points for it
The area is 198.5cm sq
The shape can be divided into a circle of
5cm radius
as diameter is 10cm
radius = d/2
and a rectangle of 12×10 cm dimensions
length is 22-( 2×5) 12cm
and breadth is 10cm
The area of the circle is pi(r square)
which is 3.14×25
= 78.5 cm sq
The area of the rectangle is l×b
which is 12×10
= 120 cm sq
The total area is thus
area of rectangle plus area of circle

Tell how many terms the expression has.
200 plus left parenthesis 5 times 3 right parenthesis minus 30 plus 3
There is/are term(s).
Answer:
There are 4 terms in the expression 200+(5∗3)−30+3. The terms are 200, 5×3, −30, and 3.
A term is a single number or variable, or a product or quotient of numbers and variables. In this expression, each of the numbers 200, 5, 3, and −30 is a term. The product 5×3 is also a term.
The terms are separated by addition and subtraction signs. The expression is evaluated by performing the operations in parentheses first, then the multiplication and division, and finally the addition and subtraction.
