what is the solution to the equation 5=2/5a
Answer:
a = 25/2
Step-by-step explanation:
5 = (2/5)*a // - (2/5)*a
5-((2/5)*a) = 0
(-2/5)*a+5 = 0
5-2/5*a = 0 // - 5
-2/5*a = -5 // : -2/5
a = -5/(-2/5)
a = 25/2
a = 25/2

Help! I’ll mark brainliest /
Jules owns a square plot of land that measures 30 yards on each side. He plans to divide the land in half by building a fence as shown by the dotted line below. how many yards of fencing does Jules need
A 15yd
B 30 yd
C 30/2yd
D30/2yd
Answer:
BD = 30√2 yd
Step-by-step explanation:
The shape of the land is a square with 30 yd side length on each side.
The fence to he built is the diagonal of the square BD.
Apply pythagorean theorem to find the number of yards of fencing (BD) he needs.
Thus:
BD² = BC² + CD²
BD² ° 30² + 30²
BD² = 1800
BD = √1800
BD = √(900*2)
BD = 30√2 yd
j - 5 = q
What is J and Q?
Answer:
There might be more to this problem that not included?
Based on the question written, J and Q would be anything that is mathematically supported.
I could a virtually endless combination, that's why I think we may be missing part of the question.
Here are some solutions:
J=11, Q = 6 11-5=6
J=12, Q= 7 12-5=7
J= 7, Q = 2 7-5=2
J = 162, Q = 157 162-5=157
Help plz if your good at finding the area of the compound figure plz help if you don’t know the answer your not needed but if you do plz help
Answer:
96cm^2
Step-by-step explanation:
We can divide it into two rectangles: 7x8 and 10x(12-8), arriving at the solution of 7cm*8cm + 10cm*4cm = 56cm^2 + 40cm^2 = 96cm^2
We can also divide it into two rectangles: 12x7 + (12-8)x(10-7), arriving at 12cm*7cm + 4cm*3cm = 84cm^2 + 12cm^2 = 96cm^2
We could also divide it to one big rectangle and one "negative" rectangle of 10x12 and -8x(10-7), arriving at 10cm*12cm - 8cm*3cm = 120cm^2 - 24cm^2 = 96cm^2

Answer:
x2= 0.11111111111 y+5= -9
Step-by-step explanation:
x2= 0.11111111111
replace x with 1/3 then multiply 1/3 by 1/3 which equals 0.11111111111
x2
1/3 2
1/3 x 1/3= 0.11111111111
y+5
replace y with -14 then add - 14 with 5 which really is subtracting -14 with 5. Which gives you -9.

You want to order a new computer. The manufacturer is offering a discount of 12% off the original price of the computer for students. With the discount, you pay $924. What was the original price of the computer?
Answer:
x - 0.12x = 924 dollars
0.88x = 924
x = 924/0.88
x = $1050 (original price)
Answer:
$1034.88
Step-by-step explanation:
this is the discount amount :
12%of924
110.88
To find the original price

Answer:
y ≥ -2/3x +2
Step-by-step explanation:
The y-intercept of the boundary line is y=2.
The next grid intersection to the right appears to be the x-intercept at x=3, which represents a "rise" of -2 and a "run" of +3 from the y-intercept.
At this point, we know the slope (rise/run = -2/3) and the y-intercept (+2) of the boundary line. We see it is a solid line, and shading is above it. This means the inequality could be ...
y = mx + b . . . . . . . . . equation for a line with slope m and y-intercept b
y ≥ -2/3x +2 . . . . . equation for the graphed inequality
__
Alternate solution
We observe that the y-intercept is +2, and the x-intercept is +3. The equation of the boundary line can be written in intercept form as ...
x/x-intercept = y/y-intercept = 1
As noted above, the line is shaded where both x- and y-values are greater than or equal to those on the line. So, the "intercept form" of the inequality could be ...
x/3 +y/2 ≥ 1
Often, we don't like fractions, so we can multiply by 6 to put this in standard form:
2x +3y ≥ 6

Additional comment
Any of these highlighted inequalities is "an inequality" that describes the graph. We don't know if you're required to write the inequality in a specific form.

The discount on a new computer was $150. This was a discount of 23 %. Step 1 of 3: What was the original selling price of the computer? Follow the problem-solving process and round your answer to the nearest cent, if necessary
Answer:
So there is an unknown number to the original price so we replace this as x,
23% of the original price will equal your new discount, now lets write it!:
23/100 x X = 150
x100 x100
23x = 15,000
Divide by 23 on both sides:
x = 652.173 around 652.17 dollars was the original price.

Answer:
Angle 2=160
Angle 3=10
Step-by-step explanation:
The rhombus is made up of two isoceles triangle.
Angle 1 measures 160.
Since the triangle is a isoceles triangle, the opposite angles of the congruent sides is equal angles to each other.
So the reamaing angles in the top triangle are equal so we can use this equation
Remeber that triangle maximum degree it can hold is 180
[tex]160 + x + x = 180[/tex]
[tex]160 + 2x = 180[/tex]
[tex]2x = 20[/tex]
[tex]x = 10[/tex]
We have two congruent triangle side they share Three sides. SSS
This means the corresponding angle of Angle 1 is Angle 2.
Angle 2=Angle 1 by CPCTC.
Angle 2=160
Angle 3 corresponds with one of the remaining congruent angles so it measures
10.

1) A sum of money is divided in the ratio 4:3.If
the larger part is $44 1) What is the small part?
2) What is the total amount? *
Answer:
Smaller part = $33 and total amount = $77
Step-by-step explanation:
Let the numbers be 4x and 3x.
The larger number is $44
ATQ,
44x = 44
x = 11
(1) Smaller number = 3x
= 3(11)
= 33
(2) Total amount
T = 33+44
T = 77
Hence, this is the required solution.

f(x) = x^2 is stretched vertically by a factor of 4 and shifted 1 unit down.
equation = ???
Answer:
f(x) = 4x² - 1
Step-by-step explanation:
The given function is; f(x) = x²
Now, when stretched vertically by a factor of 4, we have;
f(x) = 4x²
It's now shifted 1 unit down.. Thus, the final function will be;
f(x) = 4x² - 1
