The resulting equation after substitution is
5x + 4(-2x + 6) = 3
quite literally you replaced y with what it equals (as said in the second equation)
you then distribute the 4 within the parenthesis
5x + -8x + 24 = 3
You make it easier
5x - 8x +24 = 3
you combine like terms
-3x + 24 = 3
you subtract 24 from both sides
-3x = -21
you divide both sides by -3
meaning x = 7
you then use that value x = 7 and substitude it for the x in the other equation.
That makes the y equation
y = -2(7) + 6
you then solve
y = -14+6
y = 6 - 14
y = -8
2(y + 5)
use the distributive property to expand expressions.
Answer:
2(y+5)
Step-by-step explanation:
= 2y+10 simple multiplication method
Answer:
2y+10
Step-by-step explanation:
If you want to distribute 2(y+5), you're going to multiply y and 5 to 2
yx2=y2
5x2=10
Your answer should be 2y+10

Answer:
21.46
Step-by-step explanation:
we know that 10yd is the diameter of the unshaded circle. so we will use this to find out the area of the circle. if a diameter of a circle is 10yd, the area is about 78.54 (considering that pi=3.14) to find the area of the shaded region, we can pretend that the entire square is shaded, and then take the unshaded away. if the square was completley shaded, the answer would be 100. but there is a circle inside of the square unshaded, with a area of 78.54, so we need to solve for 100-78.54. this results in our final answer, 21.46

temperature 40°F on Tuesday, but then an arctic wind overnight decreased the
temperature 70°F! What was the temperature on Wednesday?
Answer:
-40
You start at -5 then you add 20 to get 15 . Then you subtract 25 from 15 to get -10. Then you add 40 to -10 to get 30. Then you have to subtract 70 from 30 to get -40 F.

Answer: 5 to the 2 power x4+100 divide by 2
Step-by-step explanation:
The expression that has a value of 100 is 5²×4 + 100/2 - 50 and has all four operations and at least one exponent.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
It is given that:
Use all four operations and at least one exponent to write an expression that has a value of 100.
The value of the expression = 100
As we know,
In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.
The number expression will be:
5²×4 + 100/2 - 50
Thus, the expression that has a value of 100 is 5²×4 + 100/2 - 50 and has all four operations and at least one exponent.

The rectangle and the trapezoid have the same area. What is the length l of the rectangle?
l=
ft
The length 'l' of the rectangle will be;
⇒ l = 18 feet
What is mean by Rectangle?
A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The rectangle and the trapezoid have the same area.
Now,
Since, The rectangle and the trapezoid have the same area.
Hence, We get;
Area of rectangle = l × 9
And, Area of trapezoid = 1/2 (24 + 12 ) × 9
= 1/2 × 36 × 9
= 18 × 9
= 162
So, We get;
⇒ l × 9 = 162
⇒ l = 162/9
⇒ l = 18 feet
Thus, The length 'l' of the rectangle will be;
⇒ l = 18 feet
