Answer:
x = 6
Step-by-step explanation:
The perimeter is the sum of the 3 sides
Sum the 3 sides and equate to 53
x + 2x + 1 + 5x + 4 = 53 , simplify left side
8x + 5 = 53 ( subtract 5 from both sides )
8x = 48 ( divide both sides by 8 )
x = 6
find the values for k
5k^2 - 4k > 0
Answer:
[tex]5k^2-4k>0[/tex]
[tex]k(5k-4)>0[/tex]
In the image attached, you want the values above 0. Thus, the values of k would be in the red area, which is
[tex]k<0[/tex] or [tex]k>\frac{4}{5}[/tex]

An Uber ride costs a flat rate to start the ride and then charges an additional amount per mile. By the 3rd mile, the total cost of the trip is $9. By the 7th mile, the total cost is $17. What is the flat rate that Uber charges and how much does it cost per mile?
Step-by-step explanation:
the function is
ride cost c = mile rate r × miles m + flat rate f
c = r×m + f
now let's put the values in we know and solve for r and f :
9 = r×3 + f
17 = r×7 + f
now, since one term is the same in both equations, we use a simple trick for speed, and we subtract the whole first equation from the second :
17 = r×7 + f
- 9 = r×3 + f
-------------------
8 = r×4 + 0
r = 8/4 = $2
9 = 2×3 + f = 6 + f
f = $3
the first rate is $3, and it costs $2 per mile.

5. acute
Answer:
Triangle number one is a right triangle. Triangle two is an equilateral triangle. Triangle three which is below triangle one is an obtuse triangle. The fourth triangle is an acute triangle.
Step-by-step explanation:
One is a right triangle because it has one right angle.
Two is an equilateral triangle because all of the three angles are 60 degrees.
Three is an obtuse triangle because one of the three angles is more than 90 degrees.
Finally, 4 is an acute triangle because all of the three angles are less than 90 degrees

A farmer harvests 850kg of parsnips.30% go to the local market and 50% go to a local supermarket.What mass of parsnips are left?
Answer:
170 kg. of parsnips are left
Step-by-step explanation:
Given:
850 kg. of parsnips
30 % to the local market
50 % to a local supermarket
Solution:
First, add the two percentages.
30 + 50 = 80%
That means 80 % of parsnips mass go to the markets.
Now let's find the mass of delivered parsnips.
Change 80% to decimal form.
80% = 0.8
Now multiply it by 850 kg.
850 x 0.8 = 680
The delivered parsnips mass is 680 kg.
Now to find the mass of parsnips left, subtract 680 to 850
850 - 680 = 170 kg.
170kg. of parsnips are left.

Write the equation of the graphed line that has a slope of 2 and passes through the point (2,-2)
Answer:
y = 2x - 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (2, - 2 ) into the partial equation
- 2 = 4 + c ⇒ c = - 2 - 4 = - 6
y = 2x - 6 ← equation of line

SOMEONE PLEASE BE FAST!!! Which pair of fractions and mixed numbers have a common denominator of 42?
Three and two-thirds and Five-sevenths
Two and one-sixth and Three-fourths
Five and three-fourteenths and One-fifth
One and four-sevenths and Five-eighths
Answer:
It's the first one. Why?
I converted all the mixed fraction into simplified form.
3 [tex]\frac{1}{3}[/tex] to [tex]\frac{11}{3}[/tex] + [tex]\frac{5}{7}[/tex]
I divided the denominator of 11/3 by 42. 42/3=14
and 5/7. 42/7, which is 6.
So I concluded the first answer was right because it didn't work out for the other variables.
I hope the answer was right, and I hope you have a great day luv. Bye!

what percentage of this grid is shaded
how many more squares need to be shaded so that 60% of the grid is shaded?
Answer:
44%, and 4
Step-by-step explanation:
The grid has 5 rows and 5 columns so we have 5*5 = 25 squares.
25 squares represent 100 % of the grid
a) In the grid 11 of the 25 total squares are blue, so if
25 squares are 100%
11 squares will be x%
x= (11* 100) / 25 = 1100/ 25 = 44 %
b) we find the number of squares that gives us 60 %
25 squares are 100%
x squares will be 60%
x= (60*25)/ 100 = 15
The question is " How many more squares " so we have to compare with the 11 given ones in part a)
15 -11 = 4
4 more squares will give 60 % blue grid.
