5 more than the sum of -1 and -12

lets start with the 2nd part, the sum of -1 and -12

sum means adding 2 things together, so -1 + -12 = <u>-13</u>

now lets work on the first part again, it said 5 MORE, more means add as well, so

-13 + 5 = -8

Given

"5 MORE than..." so we need to ADD 5, or "+5 " as the last step, so 3rd and fourth are out.

"the sum of -1 and -12" means we need to see the expression (-1)+(-12), so the second and third are out.

That leaves us with the first, let's check

5 more than the sum of -1 and -12

[-1 + (-12)]+5 => (sum of -1 and -12) add 5 to it......checks.

Which angle pairs are supplementary? Check all that apply. ∠1 and ∠2 ∠4 and ∠3 ∠4 and ∠5 ∠7 and ∠5 ∠3 and ∠6.
Alla [95]

Answer:

∠4 and ∠3

∠4 and ∠5

∠3 and ∠6.

Step-by-step explanation

Find the diagram attached

First you must note that the sum of two supplementary angles is 180°

Also, since the sum of angle on a straight line is 180°, the angles that are supplementary must lie on the same straight line.

Based on the diagram, the pair of angles that lies on the same straight line are ∠4 and ∠3, ∠4 and ∠5 and ∠3 and ∠6. If that is the case, hence this angles are supplementary.

Can someone explain this to me ?
Alex Ar [27]

Suppose you had f=6, g=2, h=3 and you were asked to find

f - g - h

You would do it by substituting the given values for the letters to get

6 - 2 - 3

And this can be simplified to

1

_____

The question at hand is basically the same. You are given values of f(x), g(x), h(x) and asked to find their signed sum.

f(x) - g(x) - h(x)

= (3x+5) - (4x²-2) - (x²-3x+1) . . . . substitute the given values

= 3x + 5 - 4x² + 2 - x² + 3x - 1 . . . use the distributive property to eliminate parentheses. A minus sign in front changes the sign of every term inside parentheses.

= x²(-4-1) +x(3+3) +(5+2-1)

= -5x² + 6x + 6 . . . . . . collect terms . . . . matches the first choice
