work out the value of x
will give brainliest
Answer:
x = 35
Step-by-step explanation:
we know that all triangles add up to 180
you first need to make an expression in which the angles equal 180
105 + 140 + x = 180
145 + x = 180
subtract 145 from both sides
x = 35
Does anyone know how to do these? I don't understand them at all... :(

Answer:
Area of rectangular garden = lxb = 10*5
= 50 sq. inch
when area increases by six times
new area = 50*6 = 300 sq inches
now,
let x be increasement in both length and width
(5+x) (10+x) = 300
50 + 5x + 10x + x² = 300
x² + 15x - 250 = 0
x²+ 25x-10x -250 = 0
x(x+25) - 10 (x+25) = 0
( x-10) (x+25) = 0
either x + 25 =0
x = -25 length can be negative
0r x-10 = 0
x = 10
so 10 inches is increase on both side

a student earned a grade of 80% on a math test that had 20 problems how many problems on this test did the student answer correctly
Answer:
16
Step-by-step explanation:
To find 80% of 20, multiply .80 x 20
.80×20 = 16
This is how you multiply percentages--put the decimal point 2 places to the left, then multiply. In this case, you're looking at 80%, so move the decimal point two places to the left
80.0 becomes .80
Then multiply that by the number you're trying to find the percentage of

Answer:
[tex]a_{n}[/tex] = - 4n + 12
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = a₂ - a₁ = 4 - 8 = - 4 , then
[tex]a_{n}[/tex] = 8 - 4(n - 1) = 8 - 4n + 4 = - 4n + 12

Can someone please help?!
Grant spent half of his weekly allowance. Then he earned $5 back by doing the dishes. What is his weekly allowance if he ended with $15?
Answer:
Grant's weekly allowance is $20.
Step-by-step explanation:
We know that Grant ended with $15. We can say that Grant's weekly allowance is x.
x/2 + 5 = 15
Now to solve:
x/2 + 5 - 5 = 15 - 5 (subtract 5 from both sides to isolate the x/2)
x/2 = 10
x/2 * 2 = 10 * 2 (multiply both sides by 2 to isolate the x)
x = 20
Grant's weekly allowance is $20.

Mke y the subject of the formula.
w=x^2-2yz
Answer:
W = x^2 - 2yz / - w
0 = x^2 - 2yz - w / +2yz
2yz = x^2 - w // 2z
y = (x^2 -w ) / 2z
So correct answer is D
