Plsss answer the following.
IRINA_888 [86]

First exercise:

a. The first prime numbers are 2,3,5,7,11,... So, the greatest prime interger between 4 and 9 is 7. A = 7.

b. Since the number line's growing direction is rightwards, going to the left means to decrease. So, point E is 4 less than point A, i.e. 7-4 = 3. E = 3.

c. The additive inverse of a number x is another number y such that x+y=0. So, we're looking form a number such that 3+O=0, and thus O = - 3.

d. This point looks a bit ambiguous to me honestly. We know that IO = 2, which I presume means that the points I and O are two units apart, but we're not told if I is two units left or right with respect to O. To solve this issue, I'm assuming that IO implies that I sits before O, and so I is two units left with respect to O. As we said in point a., two units left means two less, so we have I = -3-2 = -5. At this point, point L is halfway between -5 and -3, and thus L = - 4.

e. The sum of the coordinates of A and E is 7 + 3 = 10. Half that sum is 5, so M = 5.

In the attached image, you can see the number line filled with the points asked by the exercise.

Second exercise:

All the requests can be written as an equation in which we look for the values of x. Below you find the equation and the solutions.

107 + x = 55 \implies x = 55-107 = -52

-43 - x = 18 \implies x = -43-18 = -61

-43 - x = 18 \implies x = -43-18 = -61

55x = 0 \implies x = \frac{0}{55} = 0

\frac{x}{-1080} = -40 \implies x = (-1080)(-40) = 43200

A little side note: I've honestly never met the expression "subtract A to B", but always "subtract A from B". I assumed they mean the same thing, but if anybody thinks I'm wrong please let me know! (I'm not a native speaker, so I can only refer to the math I met during my studies).

2(x + 4) - 3(x - 5) Rewrite the expression using properties.
sergij07 [2.7K]

First, distribute 2 to x and 4, and -3 to x and -5 (distributive property)

2(x + 4) = 2x + 8

-3(x - 5) = -3x + 15

2x + 8 - 3x + 15

Next, combine like terms

2x - 3x = -x

8 + 15 = 23

-x + 23 is your answer

hope this helps
