Answer:
y = -4y = -8Step-by-step explanation:
For the first possible answer (y = -4):
Simplify: 6 + y = 2Subtract 6 from each side, so it now looks like this: y = -4I don't know how to explain the second one, I'm sorry!
Answer:
y = -8
y = -4
Step-by-step explanation:
The equation |6 + y| = 2 can only be true when 6 + y = -2 and 6 + y = 2. This is because:
|-2| = 2
and
|2| = 2
First, lets find for what y values the equation 6 + y = -2 is true. Solve for y:
6 + y = -2
Subtract 6 from both sides.
y = -8
So now we have one of the values of y.
To find the second value of y, we must solve for y in the equation 6 + y = 2:
6 + y = 2
Subtract 6 from both sides.
y = -4
So the two values of y are -8 and -4.

(a) In 2016, a company sold 9600 cars, correct to the nearest hundred.
(i) Write down the lower bound for the number of cars sold.
Answer: lower bound = 9550
Step-by-step explanation:
Since the number is rounded to the nearest hundred, the actual value is somewhere between 9550 (which rounds up to 9600) and 9649 (which rounds down to 9600).
The lower bound is: 9550
The upper bound is: 9649

For every 1 litre of water used to make a medicine, 193ml of sucrose and 61ml of saline solution are used. Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.
Explanation
1 liter = 1000 mL
For every 1000 mL of water, we need 193 mL of sucrose and 61 mL of saline solution.
The ratio is therefore 1000:193:61
We cannot simplify this ratio any further because the GCF of those three terms is 1.
A quick way to see this is to look at how 1000 = (2*5)^3 has prime factors 2 and 5, but 2 nor 5 are factors of 193 and 61. So only 1 is a factor of all three values 1000, 193, 61
4. The side lengths of a triangle are x, x – 9, and 2x + 3. If the perimeter of the triangle is 46 cm, what is the value of x?
HELPPP
Answer:
x=13

perimeter equals the sum of sides of triangle
perimeter= x+x-9+2x+3
46=4x-6
46+6=4x
4x=52
x=52/4
x=13

24+24=48
$48.56
Amanda and her best friend found an amount of $48.56 buried in a field.
What is amount?Amount is the multiplication of total number of quantities and total price.
Amount= number of quantity×price
Given that,
The amount got by Amanda and her friend is $24.28 each,
Let x represents the total amount of money.
Therefore, equation for the total amount,
x= 24.28 + 24.28
x= 48.56

Answer:
83
Step-by-step explanation:
The sum of the angles of a triangle is 180
x + 2x+1 + x+ 15 = 180
Combine like terms
4x+16 = 180
Subtract 16 from each side
4x+16-16 = 180-16
4x = 164
Divide by 4
4x/4 = 164/4
x = 41
The angles are
x=41
x+15 = 41+15 = 56
2x+1 = 2*41+1 = 82+1 = 83
The largest angle is 83
Answer:
Option (D) : 83
Step-by-step explanation:
We know that,
(2x + 1) + x + (x +15) = 180°
4x + 16 = 180°
X = 41°
Largest angle in triangle = 83

Find the value of x, y, and m
Answer:
x = 9, y = 41
Step-by-step explanation:
[tex]\because m\angle ABC = 90\degree \\
\therefore m\angle ABD+m\angle DBC = 90\degree \\
\therefore (3x+7)\degree + (5x+11)\degree = 90\degree \\
\therefore (8x + 18)\degree = 90\degree \\
8x + 18 = 90\\
8x = 90-18\\
8x = 72\\
x = \frac{72}{8}\\
\huge \red {\boxed {x = 9}} \\\\
m\angle DBC + m\angle FBC = 180\degree \\(straight \: line \: \angle 's) \\
(5x + 11)\degree + (3y+1)\degree = 180\degree \\
(5\times 9+11)\degree + (3y+1)\degree = 180\degree \\
(45+11)\degree + (3y+1)\degree = 180\degree \\
56\degree + (3y+1)\degree = 180\degree \\
(3y+1)\degree = 180\degree - 56\degree \\
(3y+1)\degree = 124\degree \\
3y + 1 = 124\\
3y = 123\\
y = \frac {123}{3}\\
