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).

Which story represents the equation six sevenths times one fourth?

Vesnalui [34]

Answer: (C) Victoria has six sevenths of a pizza. She ate one fourth of it for dinner. How much pizza did Victoria eat for dinner?

Step-by-step explanation: One clue is "of" in the story and which matches "times" in the equation sentence. The question is is about multiplication.

Words such as "more" "and" & "total" are usually clues that the question is about addition. "Give" "take" "difference" & "have/are left" are clues that there is subtraction in the process.

The roof on Crystal’s house is formed by two congruent trapezoids and two congruent isosceles triangles. She wants to put new wo

NeTakaya

Answer:

the total number of shingles is 3060

Step-by-step explanation:

Please have a look at the attached photo.

We need to find the total are of the roof.

The are of the trapezoid is:

A = 1/2 (base 1 + base 2) height

= 1/2 (20+30)*15

= 375 $ft^{2}$

The are of the triangle:

A = 1/2*base*height

= 1/2(1.5*10)

= 7.5 $ft^{2}$

=> We need to find the total are of the roof is:

The are of the 2 trapezoids + The are of the 2 triangles

= 375 $ft^{2}$ *2 + 7.5 $ft^{2}$ *2

= 765 $ft^{2}$

Given in the question that, the shingles are 1 foot by 1 foot, but they overlap by 0.75 square foot so the usable area of the shingle is only 0.25 $ft^{2}$

So the total number of shingles is:

765 $ft^{2}$ / 0.25 $ft^{2}$

= 3060

I’ll give brainlest HELP ASAP!!!<br><br> if f(x) = 2x^2 + 4, find f(3)

victus00 [196]

Answer:

f(3) = 22

Step-by-step explanation:

f(x) = 2x^2 + 4, find f(3)

f(3) = 2(3)^2 + 4

f(3) = 2 (9) + 4

f(3) = 18 + 4

f(3) = 22
