Answer:
8x+6y
Step-by-step explanation:
add the coefficients of like terms with the same variable
Solve for N
4n=2n+6
Please help
Answer:
n = 3
Step-by-step explanation:
Given
4n = 2n + 6 ( subtract 2n from both sides )
2n = 6 ( divide both sides by 2 )
n = 3
The solution is, n = 3.
What is Subtraction?Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.
here, we have,
Given
4n = 2n + 6 ( subtract 2n from both sides )
2n = 6 ( divide both sides by 2 )
n = 3

A polr has a shadow that is 15 feet long.Mary is 4 feet tall and her shadows is 10 feet tall how tall is the pile
Answer:
The pole is 6 feet tall.
Step-by-step explanation:
The height makes the perpendicular and the shadow makes the base of the triangle in the given question
Pole Mary
Height x 4
Shadows 15 10
If the height is taken along y- axis and shadow is taken along x axis
Then
tan alpha = Perpendicular/ base
for Mary Tan alpha = 4/10
For the pole = tan alpha = x/15
Comparing x/15= 4/10
x= 4*15/10= 60/10= 6
The pole is 6 feet tall.

For soccer season Ron wants to buy a new soccer ball, a pair of shorts , and a pair of soccer shoes. The ball cost $11.15, the shorts cost $7.60, and the shoes cost $13.30 Ron has $10.60. How much more money does Ron need?
Answer:
21.45
Step-by-step explanation:
Answer:
Ron needs $21.45 more
Step-by-step explanation:
soccer ball price + pair of shorts price + pair of soccer shoes price = total amount needed
11.15+ 13.30 + 7.60 = 32.05
Ron has 10.60
32.05-10.60=21.45
The length of two sides of a triangle are 4 inches and 7 inches.
What is the area to that triangle?
Answer:
Hi! answer: Area = 14
Step-by-step explanation:
When finding area we do base x height ÷ by 2
So I do 7 x 4 = 28 then I divide that by 2 and get 14 Hope this helps!
I WILL GIVE BRAINLIEST!! I really need help with this question.
Answer:
x = 70°, y = 110° , z = 85°
Step-by-step explanation:
∠ BEA and ∠ CDA are corresponding angles and congruent , then
x = 70°
x and y are adjacent angles and sum to 180°
x + y = 180°
70° + y = 180° ( subtract 70° from both sides )
y = 110°
∠ ABE and ∠ ACD are corresponding angles and congruent , then
z = 85°
The size and shape of a figure will stay the same after a translation is performed.
o True
o False
Answer: true
Step-by-step explanation:
True, because translation means just to move a figure, not to change a shapes's size, width, height, or any other property of the shape.
hello whats this ? ill give brainliest
Answer:
congruent
Step-by-step explanation:
90+90=180
so not 0 or 270
and complementary means they add up to 90 and none of that is true
so it has to be congruent
A boy pulls the handle of a lawn mower at an angle of 30° to the horizontal with a force
of 120N. Calculate the work done when the mower moves through a distance of 12.8m.
(3mks)
If the mower is pulled over a flat horizontal surface, then first get the component of the force in the direction of the mower's displacement:
(120 N) cos(30°) = 60 √3 N ≈ 103.923 N
Then the work done by the boy on the mower over a distance of 12.8 m is
(103.923 N) (12.8 m) ≈ 1330.2 Nm ≈ 1330 J

Given:
The figure of circle E. [tex]m\angle ABD=(11x-3)^\circ,m\angle ACD=(8x+15)^\circ[/tex].
To find:
The measure of arc AD.
Solution:
We know that the inscribed angles on the same arc are congruent and their measures are equal.
[tex]\angle ABD[/tex] and [tex]\angle ACD[/tex] are inscribed angles on the same arc AD. So,
[tex]m\angle ABD=m\angle ACD[/tex]
[tex]11x-3=8x+15[/tex]
[tex]11x-8x=3+15[/tex]
[tex]3x=18[/tex]
[tex]x=6[/tex]
Now,
[tex]m\angle ABD=(11x-3)^\circ[/tex]
[tex]m\angle ABD=(11(6)-3)^\circ[/tex]
[tex]m\angle ABD=(66-3)^\circ[/tex]
[tex]m\angle ABD=63^\circ[/tex]
We know that the intercepted arc is always twice of the inscribed angle.
[tex]m(Arc(AD))=2\times m\angle ABD[/tex]
[tex]m(Arc(AD))=2\times 63^\circ[/tex]
[tex]m(Arc(AD))=126^\circ[/tex]
Therefore, the measure of arc AD is 126 degrees.

Answer:
s = 17 inches
Step-by-step explanation:
Since this is a parallelogram, it has two sets of equal sides. We are given that one of the sides is 19 and the perimeter is 72. Therefore, \
72 = 2*s + 2*19
72 = 2*s + 38
34 = 2*s
s = 17
Answer:
17
Step-by-step explanation:
19 + 19 = 38
38 divided by 2 = 17
Add the given length to itself again because the other side is equal.
Which would be 38. Divide by 2 since there are two missing lengths that need to be solved (s). And your final answer is 17!

Volume Rectangular Prism Formula
V = L * W * H
Givens
L = 6
W = 6
H = 3
Solution
V = 6 * 6 * 3
V = 108
Volume Pyramid
Formula
V = 1/3 * B * H
Givens
B = 6*6
H = 4
Solution
V = 1/3 * 6*6 * 4
V = 1/3 * 36 * 4
V = 48
Total
Total = 108 + 48 = 156
