-35 - 27 - (-18) = -44
When you have two subtraction signs in a row, you can remove them and add a plus sign.
-35 - 27 - (-18) can be written as -35 - 27 + 18.
27 + (-18) can be written as 27 - 18.
27 + (-18) = 9.
<span>To finds the number of tenths in the given fraction 4/5 just multiply the numerator and denominator by 2 we get. 4*2/5*2 = 8/10. So, these is the equivalent expression for the number of tenths in 4/5.</span>
Answer:
u = - 3
Step-by-step explanation:
Calculate the slope m using the gradient formula
m = ![\frac{y_{2-y_{1} } }{x_{2-x_{1} } }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2-y_%7B1%7D%20%7D%20%7D%7Bx_%7B2-x_%7B1%7D%20%7D%20%7D)
with (x₁, y₁ ) = (- 6, 4) and (x₂, y₂ ) = (- 5, u)
m =
=
= - 7, hence
u - 4 = - 7 ( add 4 to both sides )
u = - 3
Answer:
We can split the shape into two figures;
Triangle
Trapezoid
The above shape will be a triangle and the shape below it will be considered the trapezoid.
First let's know the formula of their areas for the two:
Formula for area of a trapezoid is
A = 1/2(b1 + b2) x h
Formula for area of triangle is
A = BH x 1/2
Now let's figure out the base and height of the triangle:
4 is the base and 2 is the height, now plug in our values into the formula:
A = BH x 1/2
A = 4 x 2 x 1/2
A = 8 x 1/2
A = 8/2
A = 4, the area of the triangle is <u>4</u>
Now the trapezoid's bases and height:
The bottom base is 5, and the top base is 3, our height is 2
So plug in those values into the formula;
A = 1/2(b1 + b2) x h
A = 1/2(5 + 3) x 2
A = 5/2 + 3/2 x 2
A = 8/2 x 2
A = 16/2 which simplifies to <u>8</u>
Now add the areas for those two shapes:
4(triangle) + 8(trapezoid) = <u>12</u> is your answer.
