Using a riding lawn mower, Shane, the landscaper of a large park, can mow the lawn in 8 hours. With a small mower, her assistant Matt needs 14 hours to mow the same lawn. If Shane and Matt work together mowing the lawn, how long will it take them to mow the lawn?
Answer:
1 hour and 45 minutes
Step-by-step explanation:
I know this because you just need to divide the amount of hours that shane did it and the amount of time matt did it and then it will give you your answer
whats the answer for this??
Step-by-step explanation:
what do you mean "what's the answer for this ?"
you only need to put 3 in place of x (that's what is meant by "x is 3" or x = 3) and then simply calculate.
you know what "squaring" ("something to the power of 2" or x²) means ? it means that you have to multiply that "something" by itself.
y = 3² + 11 = 3×3 + 11 = 9 + 11 = 20
that's all there is to this.
Find the value of X in the following 3x+4=25
The answer is 7
Step-by-step explanation:
subtract 4 from 25 which is 21 than divide by 3 getting x =7
Answer:
x=7
Step-by-step explanation:
3x+4=25
3x=25–4
3x=21
X=21÷3
X=7
please help giving brainliest and big points it would be greatly appreciated :))
Answer:
X = 4 , Y = b , Z = 2a
Step-by-step explanation:
2b(2ab)² - a(2b²)² ← expand parenthesis
= 2b(4a²b²) - a(4[tex]b^{4}[/tex]) ← distribute parenthesis
= 8a²b³ - 4a[tex]b^{4}[/tex] ← factor out 4ab³ from each term
= 4ab³(2a - b)
Compare terms to XaY³(Z - b)
with X = 4 , Y = b , Z = 2a

Consider the line y=6/7 x -7. Find the equation of the line that is perpendicular to this line and passes through the point (6,-6). Find the equation of the line that is parallel to this line and passes through the point (6,-6) .
Answer:
[tex]y= -\frac76x +1[/tex]; [tex]y= \frac67x -\frac{78}7[/tex]
Step-by-step explanation:
We know from theory that two perpendicular lines have the product of their slope equal to -1. Let's find the second slope:
[tex]\frac67m = -1 \rightarrow m=-\frac76[/tex]
At this point we can just use the slope-point equation to get our first line:
[tex]y-y_0 = m(x-x_0)\\y-(-6) = -\frac76(x-6) \\y+6= -\frac76x +7\\y= -\frac76x +1[/tex]
Now, we know that two parallel lines have the same slope. Time to apply the same point-slope formula, with the original m this time.
[tex]y-(-6) = \frac67(x-6)\\y+6 = \frac67x -\frac{36}7\\y= \frac67x -\frac{36}7 -{\frac{42}7[/tex]
[tex]y= \frac67x -\frac{78}7[/tex]
Determine the inverse of the function
help please how u do dis
Answer:
WR = 16
Step-by-step explanation:
The centroid M is the point where the 3 medians intersect
The median is a segment that goes from one of the triangle's vertices to the midpoint of the opposite side.
WY is a median of the triangle , then
WY = YR = 8
WR = wy + yr = 8 + 8 = 16
is 6,8,9 a pythagorem theorem? pls help me due rn
Answer:
No, it isn't.
Step-by-step explanation:
Pythagorean theorem is x^2 + y^2 = z^2.
6^2 + 8^2 = 9^2
36 + 64 = 81
100 = 81
So, it isn't.
Answer:
No.
Step-by-step explanation:
36+64 does not equal 9² (81)

the left box should be 20 and the right box should 17.321
negitive ten is no less than two times a number plus fourteen
Answer:
Negative 12
Step-by-step explanation:
-10 ≥ 2x + 14
-24 ≥ 2x [subtract 14 from both sides]
2x ≤ -24 [read right to left]
x ≤ -12 [divide both sides by 2]

System of equations pls help me
Answer:
x=6 and y=5
Step-by-step explanation:
We can eliminate the "x" variable by adding the two equations to get 6y=30. This means that y=5.
If we plug y=5 back into one of the original equations:
5x+y=35
5x+5=35
5x=30
x=6
-5x+5y=-5
-5x+5(5)=-5
-5x+25=-5
-5x=-30
x=6
Which confirms that x=6 and y=5 are indeed the correct solutions
Answer:
x=6 ,y=5
Step-by-step explanation:
6y=30,y=5
x=6

Solve the equation for x.
x-17=-5
Answer: 12
Explanation:
add 17 to both sides
x = -5 + 17 = 12
Answer:
x = 12
Step-by-step explanation:
x - 17 = -5
x = -5 + 17
x = 12
you and your friends are going to the movies.You bought 5 tickets and spent 12.50 for popcorn.Your total was $80.Write and solve an equation to calculate the cost of each ticket
80=5x+12.5
We just use the equation y=mx+b. Where 80 is our Y, 5 is our slope, or m, and 12.5 is our constant, or b.
For the giggles I'll also solve the equation.
80-12.5=5x
67.5=5x
67.5 / 5 = x
13.5 = x
This means that each ticket was $13.5. Wow, that's an expensive ticket.
I hope this helps! :)
