#23 is x+27°=27
2x-17°=-17
#24 is x+23°=23
x+54°=54
#25 is x+79°=79
2x-37°=-37
#26 is 3x+71°=71
5x+37°=37
Step-by-step explanation:
how you ask because when it is like x+55° and 6x+88° that means its going to be a positive number.
but when it is like 5x-78° that means its going to be a negative number.
remember this +=positive and -=negative

Step-by-step explanation:
Answer:
1/4 x 7/2
First, let's convert each fraction into percentages.
1/4= 25%
7/2= 350%
Now just multiply them together.
25x350= 8750
Convert it back into a fraction.
8750% = 175/2 = 871/2 as a fraction.

2+3/4x=5/12
Rewrite the equation so that it does not have any fractions
Answer:
24+9x=5
Step-by-step explanation:
First you need to find the least common multiple of the denominators of the fractions. In this case, it would be 12. Then, multiply the entire equation by this number.
2*12=24,
3/4*12=36/4=9,
5/12*12=60/12=5.
Using these values will give your final equation: 24+9x=5
find solutions to the linear equation y=−10x+30.

a school has 2 large patios. one is rectangular and is 24 feet long by 18 feet wide. The other is square and each side is 21 feet long. Which patio has a greater area?
Answer:
The 21' by 21' square patio is larger by 9 square feet
Step-by-step explanation:
[tex]24 \times 18 = 432[/tex]
[tex] {21}^{2} = 441[/tex]
The square patio will have more area than the rectangular one.
What is an area?
The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.
Given that the school has 2 large patios. one is rectangular and is 24 feet long by 18 feet wide. The other is square and each side is 21 feet long.
The area of the rectangle is calculated as,
Area = L x W
Area = 24 x 18
Area = 432 square feet
The area of the square is calculated as,
Area = S²
Area = (21)²
Area = 441 square feet
The area of the square is greater than the area of the rectangle.

Circle YES or NO The terms 15and 9are like terms.
Circle YES or NO The terms -10xy and 9x are like terms.
Answer:
yes, and no
Step-by-step explanation:
Answer:
YES
NO
Step-by-step explanation:
15 and 9 are like terms because they can be simplified together. 15+9, 15-9, 15*9 can all be simplified further.
-10xy and 9x are not like terms because they cannot be simplified without the variables first being defined.
4. What is an equation of the line that passes through the point (3.-1) and has a slope of 2? 1) y = 2x + 5 3) y = 2x - 4 2) y = 2x-1 4) y = 2x - 7
Answer:
it's 4
Step-by-step explanation:
y - y1= m(x- x1)
y- (-1)= 2(x - 3)
y+ 1= 2x- 6
y= 2x - 7
if a ferry boat covers 28 miles in 4 hours how much distance will it cover in 12 hours?
Answer:
84 miles in 12 hour
Step-by-step explanation:
12/4 = 3
3*28=84
Answer:
84 miles.
Step-by-step explanation:
First, find the rate of miles travel per hour. It is given that the boat covers 28 miles in 4 hours. Simply divide 28 with 4:
28/4 = 7
The boat covers 7 miles per hour.
Now, multiply 12 hours with 7:
12 hours x 7 miles per hour = 84 miles per 12 hours.
84 miles is your answer.

this equals 900 so 900 people don't know the name of their rep in congress subtract 1000-900 thus 100 ppl know there rep in congress
Answer:
100 people did know they're representative

Answer:
B (same slope, lower starting point)
Step-by-step explanation:
The slope on this graph is 5, and the slope of y=5x+5 is 5, so the slopes are the same.
This graph has a y-intercept of -6, which is lower than y=5x+5's intercept of 5, so it starts lower, so B.

Answer:
[tex]n=5/2[/tex]
Step-by-step explanation:
We have the equation:
[tex]5^{2n-2}=125[/tex]
Notice that 125 is the same as 5³. So:
[tex]5^{2n-2}=5^3[/tex]
Since they have the same base, the exponents must be equal. Therefore:
[tex]2n-2=3[/tex]
Solve for n. Add 2 to both sides:
[tex]2n=5[/tex]
Divide both sides by 2:
[tex]n=5/2=2.5[/tex]
So, the value of n is 5/2.
And we're done!
Answer:
N = 2.5
Step-by-step explanation:
Ok, so try this.
125 is 5^3, right?
And in this equation, we have 5 to the power of 2n-2 is equal to 125.
You need to make sure that the exponent ends up as 3.
How would you do this?
Try substituting N for 3.
That's too big.
Try Substituting N for 2.
That's a bit too small.
What number is in between 2 and 3?
2.5 is.
N = 2.5
Check your work, and see if you came up with the same answer
Work:
2.5 x 2 = 5
5 - 3 = 2
5^3 = 125
