Answer:
Deeper than -60 is:
d < -60
On the number line, arrows goes towards left of -60, with open circle at -60
900 / 60 = 15
So, the plane traveled 360,000 meters in 15 minutes.
Generally, we do per hour. So, 15 mins * 4 = 60 mins or 1 hour. Because we multiplied the time by 4, we also need to multiply the distance by 4. 360,000 * 4 = 1440000 meters. The plane was traveling at 1440000 meters per hour.
However, it does not make sense to use meters for this long of a distance. I am going to convert it into miles (let me know if the question asks for a different unit of distance). 1 mile equals 1609.34 meters. Divide 1440000 by 1609.34 to get how many miles. 1440000 / 1609.34 = 894.7767408.
Therefore, the plane is going about 895 miles per hour--pretty fast!
It's C. The congruence statement tells you what parts of rhe polygon are congruent to each other, so basically which will have the same measure. In the statement, you can tell that PS is congruent to JL because theyre in the same "positions", just on opposite sides of the equal sign.
Answer:
1) 7m
2) 13
3) 4x^2y
4) 6s^3t^4
Step-by-step explanation:
gcf means the the greatest factor that works for both terms
1) 21m^3 and 28m
let's first find the gcf for the coefficient
21 and 28, the gcf is 7. (hopefully thats easy to explain)
the gcf for the variables is the same mindset as the numbers
m^3 and m, both can be factored by m
so the gcf is 7 * m which is 7m
2)
13x and 26
let's first find the gcf for the coefficient
13 and 26, gcf is 13
there's only one variable, x, so there's not gcf for that
so the gcf is just 13
3)
8x^2y and -12x^3y^2
let's first find the gcf for the coefficient
8 and -12, the gcf is 4 (you can also say -4)
for the variables , same mindset
x^2y and x^3y^2
the gcf for x is x^2, and for y it is just y
so 4 * x^2 * y = 4x^2y
by understanding 3) hopefully you can understand 4)
pls comment for any questions
Number 4 is C... 21
To complete the question, make the equation 5x + 15 + 3x - 3 = 180 because of supplementery angles.
Just solve for x to get 21.
Number 5 is C... 120
To complete this question, sub 21 in for X in the equation 3x - 3 to get 60. Subtract 60 from 180 to get 120.
