▹ Answer
w, 5w², 2w² and -7w
▹ Step-by-Step Explanation
Terms are the values which are seperated by the plus sign (+) or the minus sign (-).
In this case, we have w + 5w² + 2w² - 7w
We can see that there is a total of 3 signs, two plus signs (+) and one minus sign (-).
Therefore, our terms will be w, 5w², 2w² and -7w. There is a total of 4 terms in this expression.
Hope this helps!

2. What is the correct expanded form for the number 75.92?
70 + 5 + 0.9 + 0.2
70 + 5 + 0.09 + 0.002
70 + 5 + 0.9 + 0.02
700 + 50 + 0.9 + 0.02
Answer
Option 3
Step-by-step explanation:
70 + 5 = 75
0.9 + 0.02 = 0.92
75 + 0.92 = 75.92
On a coordinate plane, a line goes through (0, 1) and (5, 0). What is the equation of the line that is perpendicular to and has the same y-intercept as the given line?
Answer:
First find slope of first line given the two points
Slope is change in y over change in x
0-1 over 5-0
Slope = -1/5
Slope of the line perpendicular to this line has a slope that is the negative reciprocal.
Slope of the new line is 5
You are given the y intercept with the first point so put these things together in the slope intercept formula
Y=5x +1
Step-by-step explanation:

How many solutions can be found for the system of linear equations represented on the graph?
A) no solution
B) one solution
C) two solutions
D) infinitely many solutions
Answer:
No Solution
Step-by-step explanation:
As the two lines have the identical slope (-1/2x), that means these two lines are parallel, and therefore they have no solution.
A smart phone costs $149.99 before tax. The tax on the smart phone is 7%.
What is the total cost of the smart phone?
Answer:TC=$160.49
Step-by-step explanation:total cost=original+tax
tax=7% of 149.99
tax=0.07 times 149.99
tax=10.49993
total cost=149.99+10.49993
total cost=160.4893
round
sooo TC=$160.49
Need help with lcm (Least common multiple)
Answer:
sure can help you shoot the question
Step-by-step explanation:
You can find the least common multiple of 2 numbers by using prime factorisation to find its index notation.
Example:
6=2×3
9=3^2
So to find the LCM of these to find the LCM of these numbers, you need to take the number with the higher index notation and the remaing factor and multiply them.
Example:
LCM(6,9)=2×3^2
=18

Write 206 in base 7
Answer:
413_7
Step-by-step explanation:
Convert the following to base 7:
206_10
Hint: | Starting with zero, raise 7 to increasingly larger integer powers until the result exceeds 206.
Determine the powers of 7 that will be used as the places of the digits in the base-7 representation of 206:
Power | \!\(\*SuperscriptBox[\(Base\), \(Power\)]\) | Place value
3 | 7^3 | 343
2 | 7^2 | 49
1 | 7^1 | 7
0 | 7^0 | 1
Hint: | The powers of 7 (in ascending order) are associated with the places from right to left.
Label each place of the base-7 representation of 206 with the appropriate power of 7:
Place | | | 7^2 | 7^1 | 7^0 |
| | | ↓ | ↓ | ↓ |
206_10 | = | ( | __ | __ | __ | )_(_7)
Hint: | Divide 206 by 7 and find the remainder. The remainder is the first digit from the right.
Determine the value of the first digit from the right of 206 in base 7:
206/7=29 with remainder 3
Place | | | 7^2 | 7^1 | 7^0 |
| | | ↓ | ↓ | ↓ |
206_10 | = | ( | __ | __ | 3 | )_(_7)
Hint: | Divide the whole number part of the previous quotient, 29, by 7 and find the remainder. The remainder is the next digit.
Determine the value of the next digit from the right of 206 in base 7:
29/7=4 with remainder 1
Place | | | 7^2 | 7^1 | 7^0 |
| | | ↓ | ↓ | ↓ |
206_10 | = | ( | __ | 1 | 3 | )_(_7)
Hint: | Divide the whole number part of the previous quotient, 4, by 7 and find the remainder. The remainder is the last digit.
Determine the value of the last remaining digit of 206 in base 7:
4/7=0 with remainder 4
Place | | | 7^2 | 7^1 | 7^0 |
| | | ↓ | ↓ | ↓ |
206_10 | = | ( | 4 | 1 | 3 | )_(_7)
Hint: | Express 206_10 in base 7.
The number 206_10 is equivalent to 413_7 in base 7.
Answer: 206_10 =413_7

Evaluate 3D4C+ 4BCE in base 16
In base 16, the numbers 10-15 are denoted by the letters a-f. So in the units place, we have
c₁₆ + e₁₆ = 12 + 14 = 16 + 10 = 1a₁₆
Carry the 1 to the next place value:
4₁₆ + c₁₆ + 1₁₆ = 4 + 12 + 1 = 16 + 1 = 11₁₆
Carry the 1:
d₁₆ + b₁₆ + 1₁₆ = 13 + 11 + 1 = 16 + 9 = 19₁₆
Carry the 1:
3₁₆ + 4₁₆ + 1₁₆ = 3 + 4 + 1 = 8₁₆
So, we end up with
3d4c₁₆ + 4bce₁₆ = 891a₁₆

It costs $2.50
to rent bowling shoes. Each game costs $2.25
. You have $9.25
. Write and solve an equation to find how many games x
you can bowl.
Answer:
$2.50 can be your constant because you will have to pay it once in order to bowl. $2.25 can be the coefficient of the variable. You can form the equation now. y is total price while x is how many games you can bowl.
Now that you have the equation, you can solve. Knowing that you have $9.25, just plug in that value in the y
Now, just simply solve for x and you will find the answer to the second part of the question. You will get x=3

Shampoo can be bought in 5 gallon pails. The groomer uses 16 ounce bottles to to hold the shampoo. How many bottles can he get out of the 5 gallon pail?
Answer:
The groomer can get 40 bottles out of the 5 gallon pail.
Step-by-step explanation:
A gallon contains 128oz (ounces)
128/16=8
8 bottles/gallon
times both sides by 5
40 bottles/5 gallons
Therefore the groomer can get 40 bottles out of the 5 gallon pail
determine the value of x (put number value)
Answer:
x = 8
Step-by-step explanation:
Alternate Interior angles are equal to each other;
8x - 4 = 60
Add 4 to both sides;
8x = 64
Divide both sides by 8;
x = 8
What’s that answer for
9xr -8
80
Hey there!
This is a transversal with same-side interior angles. Same-side interior angles always add up to 180. So you add 9x-8 plus 80, which should equal 180. You then have your equation and then solve for x.
Let me know if you need more help. We just finished transversals in Geometry.

Mrs. Williamson had 18 students in her homeroom at the beginning of the school year and 24 students at the end of the year. What was the approximate percent increase in the number of students in Mrs. Williamson’s homeroom?
Answer:
The approximate % increase was around 33%
Step-by-step explanation:
Divide 24 by 18 and you convert the decimal into a percent which is just multiplying it by 100
There was an increase of 33.33 percent in Miss Williamson‘s homeroom
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then multiply it with b so that we collect b items per 100 items.
Since Percentage increase in the number of students can be calculated as;
=((Final number-Initial number)/Initial Number)×100
where the Initial number of students=18 students
Final number of students=24 students
Now substituting;
((24-18)/18)×100
=(6/18)×100
=33.33% increase
Hence, there was an increase of 33.33%.
