Answer:
x=1,y=2
-2x-4y= -10 maltiple by -1 then 2x +4y
-7x-4y= -15
therfore 2x+4y=10
-7x-4y=-15 to find x or y you must zero one of them
ther fore 4y-4y=0
then 2x+(-7x)= -5x
-5x=10 +(-15) =-5
-5x = -5
divide by -5 both side,
x =1
to get the value of y the value of x supersed in to equation
-2(1) -4y = -10
-4y =-10 +2
-4y = -8 both dived by -4
y=2
How much would it have rained each month if the total amount rain (11 inches) was redistributed equally among the 12 moths of the year?
Answer:
Total rainfall in one month [tex]0.9167[/tex] inches
Step-by-step explanation:
The total rainfall around an year is equal to [tex]11[/tex] inches
There are 12 months in an year.
Total rainfall in one month is equal to total rainfall in an year divided by number of months
Total rainfall in one month
[tex]\frac{11}{12} = 0.9167[/tex] inches
Please solve needed as soon as possible thank you I really appreciate it
Answer:
143
Step-by-step explanation:
Substitute n=3 into the problem
6([tex]3^{3}[/tex])-2([tex]3^{2}[/tex]) +3-4
Then figure out squared and power by 3
6(27)-2(9)+3-4
Next multiply
162-18+3-4
Finally, add and subtract
144+3=147
147-4=143

of 2/3 foot?
Answer:
V= 512 inches or, 42.67 feet
Step-by-step explanation:
So a cube has the same length on all sides so you would multiply length times with times area or V = a^3
So, 2/3 foot is equal to 8 inches so you would do V = 8^3 which would get you the answer,

Answer: x= 30
Step-by-step explanation:
These are corresponding angles which means they are equal. (2x+25) = (3x-5). Subtract 2x from both sides. 25 = x-5. Add 5 to both sides. 30 = x

1. Horizontal streets are parallel to each other. The angle measure of the two streets that intersect at Cathy’s Coffee is 95 degrees.
(a) Suppose you are traveling northeast from Ivan’s Ice Cream and turns West at Isabel’s Ice Cream. What is the measure of the angle created by your turning? Explain your answer in terms of what angles are congruent, supplementary, etc. to each other and why.
(b) Suppose you are traveling southwest from Beverly’s Burgers and turn East at Bob’s Burgers. What is the measure of the angle created by your turning? Explain your answer in terms of what angles are congruent, supplementary, etc. to each other and why.
(c) Suppose you are traveling southwest from Beverly’s Burgers and turn West at Connie’s Coffee. What is the measure of the angle created by your turning? Explain your answer in terms of what angles are congruent, supplementary, etc. to each other and why.
Answer:
A)
45 degrees, and it is congruent.
90/2 = 45
Since it is an Alternate Interior, it is congruent.
B)
45 degrees. It is also congruent since it is an Alternate Exterior.
C)
135 degrees. It is a linear angle/linear pair.

In ΔDEF, d = 6.4 inches, e = 7.8 inches and ∠F=33°. Find the length of f, to the nearest 10th of an inch.
9514 1404 393
Answer:
4.3 in
Step-by-step explanation:
The Law of Cosines is applicable when you have two sides and the angle between them. The third side satisfies ...
f² = d² + e² -2de·cos(F)
f² = 6.4² + 7.8² -2·6.4·7.8·cos(33°) ≈ 18.0671
f ≈ √18.0671 ≈ 4.2505
The length of f is about 4.3 inches.

Shop keeper buys a television from a manufacture the shopkeeper sells the television for $ 2700 at a profit 20% how much money did the shop keeper pay the manufacture for the television
Answer:
$3,240
Step-by-step explanation:
The computation of the money that have to be paid by the shopkeeper to the manufacture is shown below:
Given that
the sale price of television is $2,700
And, the profit is of 20%
So, the price paid is
= $2,700 + $2,700 × 20%
= $2,700 + $540
= $3,240

explain how to find cot, sec, csc
Answer:
The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x . The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x . = tan 5π 4

The length of a rectangle is 16 units more than its width. The area of the rectangle can be expressed as
x^4 – 64.
Which expression represents the width of the rectangle?
The width of the rectangle represented by the expression (x⁴ – 64)/x.
What is rectangular shape?A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle.
Given:
The length of a rectangle is 16 units more than its width.
Let the length is x units.
Then width = (x + 16) units.
The area of the rectangle can be expressed as
x⁴ – 64 = length x width
x⁴ – 64 = x (x + 16)
x + 16 =(x⁴ – 64)/x
Therefore, the width expression is (x⁴ – 64)/x.

PLEASE HELP ILL GIVE BRAIN
Answer:
Step-by-step explanation:
15. (-4-3)/(-5-0)= -7/-5= 7/5
y - 3 = 7/5x - 0
y = 7/5x + 3
16. (-2-3)/(4-0)= -5/4
y - 3 = -5/4x - 0
y = -5/4x + 3
17. (-3+5)/(0+3)= 2/3
y + 5 = 2/3(x + 3)
y + 5 = 2/3x + 2
y = 2/3x - 3
18. (-2-2)/(0+4)= -4/4= -1
y - 2 = -1(x + 4)
y - 2 = -x - 4
y = -x - 2
19. y - 3 = 1/2x - 0
y = 1/2x + 3
20. y - 2 = -(x + 1)
y - 2 = -x - 1
y = -x + 1
21. perp. -5/3
y + 5 = -5/3x + 0
y = -5/3x - 5
22. perp. 1/2
y + 1 = 1/2(x + 4)
y + 1 = 1/2x + 2
y = 1/2x + 1
23. perp. 3/4
y + 5 = 3/4(x + 4)
y + 5 = 3/4x + 3
y = 3/4x - 2
24. perp. 7/5
y - 4 = 7/5(x - 5)
y - 4 = 7/5x - 7
y = 7/5x - 3

Step-by-step explanation:
Roger jarred 15 liters of jam after 2 days. How much jam did Roger jar if he spent 6 days making jam?
Answer: 45 liters
Step-by-step explanation:
If Roger jars 15 liters of jam in 2 days, we can divide to see how much liters of jam Roger can jar in 1 day. We can divide 15 by 2 to find how much jam can be jarred in one day.
15 / 2 = 7.5.
Roger can jar 7.5 liters of jam every day.
Now we can multiply 7.5 by 6 to find how much jam Roger can jar at the end of 6 days.
7.5 x 6 = 45.
Therefore, Roger can jar 45 liters of jam in 6 days.
