Answer:
Step-by-step explanation:
[1] 5x + 2y = 4
[2] 3x + 6y = -12
Graphic Representation of the Equations :
2y + 5x = 4 6y + 3x = -12
// Solve equation [2] for the variable y
[2] 6y = -3x - 12
[2] y = -x/2 - 2
// Plug this in for variable y in equation [1]
[1] 5x + 2•(-x /2-2) = 4
[1] 4x = 8
// Solve equation [1] for the variable x
[1] 4x = 8
[1] x = 2
// By now we know this much :
x = 2
y = -x/2-2
// Use the x value to solve for y
y = -(/2)(2)-2 = -3

Answer:
2
Step-by-step explanation:
sum of angles in a triangle is 180
(26x - 2) + 70 + 60 = 180
26x -2 = 180 - 70 - 60
26x - 2 = 50
26x = 52
x = 2
hope this helped
Answer:
D) 2
Step-by-step explanation: The interior angles of triangles will ALWAYS add up to 180 degrees. In this case 2 angles are already provided, 70 and 60, so adding those together (130) the remaining angle must be 50 (180-130=50). In 26x-2=50, x=2 is the only possible answer. (Feel free to ask any questions if you don't understand anything I said!)

Two friends shop for fresh fruit. elena buys a watermelon for $7.65 and 4 pounds of cherries. taniy buys a pineapple for $2.25 and 3 pounds of cherries. use the variable p to represent the price, in dollars, per pound of cherries.
Answer:Answer: 5.2-p
Step-by-step explanation:
Let p be the price, in dollars, per pound of cherries.
Given : .Jackson buys a watermelon for $7.65 and 5 pounds of cherries.
Cost of 5 pounds of cherries = 5p
Now,
Cost of fruits to Jackson = 7.65+5p (in dollars)
Tim buys a pineapple for $2.45 and 4 pounds of cherries.
Cost of 4 pounds of cherries = 4p
Now,
Cost of fruits to Tim = 2.45+4p (in dollars)
Amount spent by Jackson more than Tim = (Cost of fruits to Jackson)-(Cost of fruits to Tim)
= 7.65+5p -(2.45+4p)
= 7.65+5p -2.45 - 4p
= 5.2-p
Hence , the required expression in terms of p = "5.2-p"

Answer:
Step-by-step explanation:
1) All the sides are equal. So it is an equilateral triangle. SO, all the angles are equal
x = 60
2) In this triangle, two sides are equal. so, it is an isosceles triangle.
In isosceles triangle, angles opposite to equal sides are equal

Find the exact value of x.

Answer:
6.73
Step-by-step explanation:
Remark
There might be an easier way to do this problem. I'm certain I don't know what it is. Begin by called WY = y
Givens
WY = y
WZ = x
XW = 25 - y
XZ = 24
YZ = 7
Equations
x^2 + y^2 = 7^2
(25 - y)^2 + x^2 = 24^2
Solution
x^2 = 7^2 - y^2
x^2 = 24^2 - (25 - y)^2
Since both xs are the same, you can equate the right side of the equations.
7^2 - y^2 = 24^2 - (25 - y)^2 Expand the brackets
7^2 - y^2 = 24^2 - (625 - 50y + y^2) Remove the brackets.
7^2 - y^2 = 576 - 625 + 50y - y^2 Cancel the y^2. Combine 576 and 625
49 = - 49 + 50y Add 49 to both sides
98 = 50y Divide by 50
y = 1.96
Now use y to find x
x^2 + y^2 = 7^2
x^2 = 7^2 - 1.96^2
x^2 = 45.1584
x = 6.72
9514 1404 393
Answer:
x = 6.72
Step-by-step explanation:
The triangles are all similar, so the ratios of corresponding sides are the same.
short leg/hypotenuse = 7/25 = x/24
x = 24(7/25)
x = 6.72

$73 is what percent of $125
Answer: The question $73 out of 125 is 58.40%
Step-by-step explanation:
$73 out of 125 is what percent Answer: The question $73 out of 125 is 58.40%, which is the same as 73/125 as a percent. This can be solved using this calculator above
The $73 is approximately 58.4% of $125.
To find what percent $73 is of $125, we can use the following formula:
Percent = (Part / Whole) * 100
In this case, $73 is the part and $125 is the whole.
Substituting these values into the formula:
Percent = (73 / 125) * 100
Dividing 73 by 125:
Percent = 0.584 * 100
Multiplying 0.584 by 100:
Percent = 58.4
Therefore, $73 is approximately 58.4% of $125.
