help ill give brainlest pls

Let's say we start with the true statement that 2 < 5

Multiplying each of those numbers by -1 means we have...

If the inequality sign stayed the same, then we'd have the false statement -2 < -5. Use a number line to see why this is false. Note how -2 is to the right of -5, so it should be larger.

To fix this error, we flip the inequality sign.

So we go from 2 < 5 to -2 > -5

Rule: Multiplying both sides by a negative number always flips the inequality sign.

Answer:

The simplified answer is 7w - 12.

Step-by-step explanation:

-1(w+4) + 2(4w-4)

(-w -4) + (8w - 8)

7w - 12

Answer:

7w - 12

Step-by-step explanation:

-(w+4)+2(4w-4)

Step 1: Distribute

In this equation, there are two things being distributed, the -(w+4) and the 2(4w-4). Looking at -(w+4) makes you think that there is nothing to distribute but actually there is. Treat the - like a -1 so that it looks like -1(w+4) and then we distribute normally.

-1 x w = -w

-1 x 4 = -4

Put it together and you have:

-w-4

Then the 2(4w-4), with this, we need to distribute the 2 into the 4w and -4. To do this, you just multiply the numbers.

2 x 4w = 8w

2 x -4 = -8

Put those together and you have:

8w-8

After distributing, the equation should like:

-w-4+8w-8

Step 2: Combine Like-Terms

In the remaining equation, there are 4 things we can combine. The -w and 8w, and the -4 and -8. The reason that we are doing it in this order is because you cannot combine a number with a variable, like combining -4 with 8w. Now we just add (or subtract).

8w - w = 7w

-4 - 8 = -12

Leaving us with the fully simplified equation:

7w - 12

Answer:

D. 204 [tex]ft^{2}[/tex]

Step-by-step explanation:

the center square 11b x 12h = 132

17 - 11 = 6/2 = 3 this is the base for each of those right angles

3 x 12 = 36 x 2 = 72

132 + 72 = 204 [tex]ft^{2}[/tex]

Answer:

its d i think sorry if im wrong

Step-by-step explanation:

for 1 serving the ratio is 1 : 2

for 2 servings the ratio is 2 : 4

so by looking at the two ratios above you can see that

for two servings the ratio 1 : 2 is multiplied by two

so the answer for 5 servings is 5 : 10

so no matter the number of servings when you simplify the ratio the ratio you should obtain (as in this case) should be 1:2 which the ratio for 1 serving.

hope this helped :)

Answer:

0.66653334

Step-by-step explanation:

The area of the face of the square is the side length x the side length. So 0.3333 x 0.3333 = 0.11108889. Since a square has 6 sides, multiply 0.11108889 with 6. So it equals 0.66653334.

Answer:

CE= 9cm, DE= 5cm, CD= 10.2956cm

Step-by-step explanation:

Let E be the point of the other triangle.

Using Pythagoras' Theorem,

CD= square root symbol (CE^2 + DE^2)

= square root symbol (9^2+5^2)

= 10.2956cm (6 sf)

Answer:

The x's in the coordinates are not supposed to be negative; the y's should be negative instead.

Step-by-step explanation:

If the x's are negative, it will flip the triangle over the y-axis; therefore, the y's have to be negative instead, which will flip it over the x-axis.

Answer:

The x's in the coordinates are not supposed to be negative; the y's should be negative instead.

Answer for Practice 8-4:

1. Right, Scalene

2. Acute, Isosceles

3. Obtuse, Scalene

4. Isosceles

5. Scalene

6. Equilateral

7. Scalene

8. Acute

9. Obtuse

10. Right

11. Right

12. This cannot be done because a right triangle always has two acute angles (cannot be right-angled and obtuse-angled at the same time)

14. Can't be done because a scalene triangle has no congruent sides, while isosceles triangles have two equal sides and two equal angles.

9: 9 multiplied by y

10:x minus eight equals fourteen

11: y divided by twelve equals 24

12: k plus twelve

hope i helped!

Answer:

9)  9 times a number

10)  14 is the difference between a number and 8

11)  24 is the quotient of a number and 12

(or "24 is a number divided by 12")

12)  A number increased by 12

Step-by-step explanation:

There are several ways of writing these into a verbal phrase, but this is how I would do it:

9)  9 times a number

10)  14 is the difference between a number and 8

11)  24 is the quotient of a number and 12

(or "24 is a number divided by 12")

12)  A number increased by 12
