5x + 2y = 18
-5x + 5y = 45
Answer:
the answer for this problem is (x,y)=(0,9)
Answer:
y = 9
x = 0
Step-by-step explanation:
5x + 2y = 18
-5x + 5y = 45 add two equations up
5x + 2y -5x + 5y = 18 + 45 add like terms (note that, 5x will eliminate -5x)
7y = 63 divide both sides by 7
y = 9 to find the value of x we can use this information
5x + 2y = 18 replace y with 9
5x + 2*9 = 18
5x + 18 = 18 subtract 18 from both sides
5x = 0 and x = 0
Help please it’s due
Step-by-step explanation:
Since ABC is a triangle,
Angle A + Angle B + Angle C = 180 (Sum of angles in a triangle)
given Angle A = 3x + 1
Angle B = 4x - 17
Angle C = 5x - 20
[tex]3x + 1 + (4x - 17) + (5x - 20) = 180 \\ 3x + 4x + 5x + 1 - 17 - 20 = 180 \\ 12x - 36 = 180 \\ 12x = 180 + 36 \\ 12x = 216 \\ x = 216 \div 12 \\ = 18[/tex]
Now substitute x into all 3 angles.
A = 3(18) + 1 = 54 + 1 = 55 degrees
B = 4(18) - 17 = 72 - 17 = 55 degrees
C = 5(18) - 20 = 90 - 20 = 70 degrees
Since Angle A = Angle B but not equal to Angle C,
Triangle ABC is a isosceles triangle as 2 angles must be the same for it to be a isosceles triangle.
Answer:
it is C

write a statement that correctly describes the relationship between these two sequences: 2, 4, 6, 8, 10 and 1,2,3,4,5.
Answer:
The relationship between these two sequences is it always doubles. When we look at each sequence, 1, 2, 3, 4, 5, each number is multiplied by 2 to create the other sequence.
1 x 2 = 2.
2 x 2 = 4.
3 x 2 = 6.
4 x 2 = 8.
5 x 2 = 10.
When we arrange these numbers, 2, 4, 6, 8, 10, this is the exact sequence as before. Therefore, this is the relationship.
Answer: 2, 4, 6, 8, 10, < |
|
Step-by-step explanation: | if you just arange the numbers to 1 x 2 = 2 |
2 x 2 = 4 |
2 x 3 = 6 |

Find the circumference of the semi circle 7cm
Given:
A semicircle with radius 7 cm.
To find:
The circumference of the given semi circle.
Solution:
We know that,
Circumference of a semi circle = Half of circumference of the circle + Diameter
[tex]=\dfrac{1}{2}(2\pi r+d[/tex]
[tex]=\pi r+2r[/tex]
Putting [tex]\pi=\dfrac{22}{7},r=7[/tex], we get
Circumference of the semi circle [tex]=\dfrac{22}{7}(7)+2(7)[/tex]
[tex]=22+14[/tex]
[tex]=36[/tex]
Therefore, the circumference of the given semi circle 36 cm.
Susan estimated she would spend $250 on school clothes at the start of the school year. She actually ended up spending only $230. What was her percent of error in her calculations?
Answer:
8.70%
Step-by-step explanation:
Percentage error = (difference between estimated value and actual value / actual amount spent) x 100
difference between estimated value and actual value = estimated value - actual amount
$250 - $230 = $20
($20 / $230) x 100 = 8.6957%

How does the concept of trust relate to debt?
Answer:
A trust can protect your assets for the next generation. However, if you have debt, the trust will not necessarily protect assets from creditors. If you or your beneficiaries file for bankruptcy, for example, the trust could be seized for repayment of debts.

Essentially, what we're looking at here are two alternate interior angles.
Wait. What? Alternate interior angles?
It sounds like some super fancy math jargon, but it's a fairly simple concept that I'll try my best to explain. First, let's look at lines L and M as two parallel lines, meaning that these two are lines with equal slopes, and will never intersect. See that line that goes in between the parallel lines L and M? That's called a transversal. It's basically a line that goes through two parallel lines.
Now we know that there's a transversal going through the parallel lines. So what? Well, there's a couple of special attributes to transversals. See the two angles, 7x-7 and 4x+14? As you can tell, these two angles alternate in the interior space between the transversal and the parallel lines.
Alternate interior angles are equal. There's a way to prove that they're equal, but I won't bore you with the specifics since that's not what the question's asking.
If the angles need to be equal for lines L and M to be parallel, we can make an equation that'll solve for x:
7x - 7 = 4x + 14
Subtract 4x from both sides:
7x - 4 x - 7 = 4x - 4x + 14
3x - 7 = 14
Add 7 to both sides:
3x - 7 + 7 = 14 + 7
3x = 21
Divide both sides by 3 to completely isolate x:
[tex]\frac{3x}{3}[/tex] = [tex]\frac{21}{3}[/tex]
x = 7
And that's our answer! If you need me to explain anything any further, just ask!

Which organisms are examples of decomposers?
A. rabbits
B. lions
C. fungi
D. trees
Answer:
C. fungi
Step-by-step explanation:
Here only Fungi is an example of decomposer.
Rabbits and lions are examples of consumers.
Trees are an example of producers.
The following list defines and provides examples of the feeding (trophic) levels that comprise food webs:
Producer: organism on the food chain that can produce its own energy and nutrients. Examples: grasses, Jackalberry tree, Acacia tree
Primary consumer/herbivore: organism that eats mainly plants. Examples: cows, impalas, warthogs, zebras
Secondary consumer/carnivore: organism that eats meat. Examples: leopard, lion
Omnivore: organism that eats a variety of organisms, including plants, animals, and fungi. Examples: humans, aardvarks
Decomposer/detritivores: organisms that break down dead plant and animal material and waste and release it as energy and nutrients in the ecosystem. Examples: bacteria, fungi, termites
Scavenger: animal that eats dead or rotting animal flesh. Examples: vultures, hyenas
Insectivore: organism that mostly eats insects. Example: Red-billed oxpecker
Answer:
C. Fungi
B. Lions
Step-by-step explanation:
C. fungi are called decomposers because they break down the dead and decaying organic matter into simpler substances such as carbon dioxide, water, simple sugars, and mineral salts and provide the nutrients back to the soil
B. A decomposer is a living thing that gets energy by breaking down dead plants and animals, lions eat other animals to get energy.
A man flies a kite and lets out 100 feet of string. The angle of elevation of the string is 52°. How far away is the man from the spot directly under the kite?
Answer:
61.57 ft
Step-by-step explanation:
Look at the picture. You need to find the base value.
so we can sue the cosine formula here.
cos x° = adjacent / hypotaneous
cos 52 ° = adj / 100
adjacent = 100 cos 52°
=61.57 ft
Answer:
the man is 61.6 ft away from the spot directly under the kite.
Step-by-step explanation:
in order to find the bottom length which is b we need to First find the height of this right angle triangle.
to find the height we need to use sin:
sin 52° = X/100
sin 52° * 100 = h
h= 78.8 ft
next we can find b which is the base of the triangle.
a^2+b^2=c^2
100^2 +b^2 = 78.8^2
100^2 -78.8^2 = b^2
b^2= 3790.56
b= √3790.56
b= 61.6 ft
therefore the man is 61.6 ft away from the spot directly under the kite.

23. Three businessmen A, B and C enter into
partnership and agree to share the total
profit in the ratio of their investments. A
invested GH¢450, B invested GH¢150
and C invested GH¢600. C received a
profit of GH¢24.70, find
i) the total profit.
ii) the profits made by A and B.
Step-by-step explanation:
A invested 450
B invested 150
C invested 600
total investment was 1200
share of A is 450/1200 = .375
share of B is 150/1200 = .125
share of C is 600/1200 = .5
C received a profit of 24.70.
that would be .5 of the total profit.
if we let x = total profit, we get .5 * x = 24.70
solve for x to get x = 24.70 / .5 = 49.40
A share of total profit = .375 * 49.4 = 18.525
B share of total profit = .125 * 49.4 = 6.175
C share of total profit .5 * 49.4 = 24.7
total profit = 49.4 as we had calculated earlier.
If m Z1 = 11x + 5 and m2 = 8x - 15, find m2.
A.) 75
B.) 115
C.) 10
D.) 65
Answer:
D) 65
Step-by-step explanation:
<1 = 11x + 5
<2 = 8x - 15
These angles are supplementary so,
11x + 5 + 8x - 15 = 180
19x - 10 = 180
19x = 190
x = 10
m<2:
8x - 15
8(10) - 15
80 - 15
