Answer:
x = 35
Step-by-step explanation:
angles in a triangle add up to 180.
x + 11 + 3x + 1 + x - 7 = 180
combine like terms
5x + 5 = 180
subtract 5 from both sides of the equation
5x + 5 - 5 = 180 - 5
5x = 180 - 5
5x = 175
divide both sides of the equation by 5
5x/5 = 175/5
x = 175/5
x = 35

Answer:
X = 12
Step-by-step explanation:
When a number increased by 4
Let that number = x
x + 4
is doubled...
2(x + 4)
the result is the same
=
when the number is increased by 20
x + 20
Find the number
2 (x + 4) = x + 20
2x + 8 = x + 20
2x - x = 20 - 8
x = 12
What does X equal? X equals 12
Check:
Insert the x = 12 into the equation;
2 (x + 4) = x + 20
2 (12 + 4) = 12 + 20
2 (16) = 12 + 20

Answer:
AB = 6 units
Step-by-step explanation:
Given A(8, 3 ) and B(2, 3 )
Since the y- coordinates in both points are 3 then this is a horizontal line.
The length of AB is then the difference of the x- coordinates, that is
AB = 8 - 2 = 6 units

2)Same for this. 4^2+5^2= 9^2
3)a^2+b^2 = ab^2 because since a and b are different letters/variables you cannot combine them therefore it is just ab.
4) (-1)^2 = 1 because -1 multiply by -1 again you would get positive 1. Next you do 1+0^2 = 1. Because 0^2 is just 0 because 0times 0 =0 so 1+0 = 1

Timothy bought groceries two days during the week: • Timothy purchased $11.25 worth of groceries and paid $12.15 after taxes on Monday • Timothy paid $59.13 after taxes on a purchase of groceries that cost $54.75 on Friday Which equation models the relationship between the cost of groceries after taxes, and the cost of groceries before taxes?
Answers
Answer: See explanation
Step-by-step explanation:
You didn't give the options but let me help out.
Timothy purchased $11.25 worth of groceries and paid $12.15 after taxes on Monday.
We would solve this using direct proportion.
y = kx.
12.15 = 11.25k
k = 12.15 / 11.25
k = 1.08
Timothy paid $59.13 after taxes on a purchase of groceries that cost $54.75 on Friday.
y = kx.
59.13 = 54.75k
k = 59.13 / 54.75
k = 1.08
The equation that models the relationship will be:
y = 1.08x

Draw the graphs of the lines below on the same grid to find the coordinates of the point of
intersection.
y = x
y = 3x - 4
Answers
Answer:
(2,2) is the solution of the given lines.
Step-by-step explanation:
Given that,
y = x ..(1)
y = 3x-4 ...(2)
We need to find the coordinates of the point of intersection.
From equation (1) and (2).
x=3x-4
4 = 3x-x
4 = 2x
x = 2
Also,
y = 2
Hence, the coordinates of the point of intersection is (2,2).How is this equation correctly solved?

Answer:
v = $312.5
Step-by-step explanation:
Let
Value of the gem stone = v
Weight of the gemstone = w
v = k * w²
Where,
k = constant of proportionality
w = 4 carat
v = $200
v = k * w²
200 = k * 4²
200 = k * 16
200 = 16k
k = 200/16
k = 12.5
Find v when w = 5 carat
v = k * w²
= 12.5 * 5²
= 12.5 * 25
= 312.5
v = $312.5
