A: 0 -6 = -6

Its at 0 and I up the -3 together twice getting -6 and subtracted it off the 0.

B: 0 -15 = -15 Same as above

C: divided the -3 by 2 and got -1.5. Subtract it off the 0 to get -1.5.

D: 0 + 3 = 3 Reverse the way i did it above to get the answer.

E: 0 + 9 same as above

F: Add 3 times 4 to 1.5 to get the answer 13.5

Have a good day!

The temperature after 2 hours, 5 hours and half an hour are respectively;

-6°C, -15°C and -1.5°C

We are told that the current temperature is 3°C. If the current falls at a constant rate of 3°C per hour. Then;

1) After 2 hours, temperature will be;

0 - (2 * 3) = -6°C

2) After 5 hours, temperature will be;

0 - (3 * 5) = -15°C

3) After half an hour, the temperature will be;

T = 0 - (1/2 * 3)

T = -1.5°C

4)At 1 hour ago, the temperature is;

T = 0 + (1 * 3) = 3°C

5) At 3 hours ago, the temperature is;

T = 0 + (3 * 3)

T = 9°C

6) At 4.5 hours ago, the temperature is;

T = 0 + (3 * 4.5)

T = 13.5 hours

Answer:

to do this question, add width + height. 4/6 + 2/5 are not normally add-able. So to correct this, we find the most common factors. There is 1, 5, and 6 at highest. 5 and 6 share a high number multiple if you combine them. This multiple is 30. So now, keep, change, flip.

4x2 is 8.

6x5 is 30.

I would say the answer should be eight thirtieths.

Step-by-step explanation:

To multiply 7/10 x 2/4

Simply, multiply 7 x 2 and 10 x 4

7 x 2 will get you 14, use 14 as your numerator

10 x 4 will get you 40, that will be your denominator

Answer:

2, 6, and 7

Yes, the smallest 2 sides sides add up to be larger than the longest side.

3, 3, and 3

Yes, any 2 sides sides add up to be larger than the other side. These sides would form an equilateral triangle.

5, 7, and 12

No, the smallest 2 sides sides do not add up to be larger than the longest side. 5 and 7 add up to be equal to 12 but not larger.

Step-by-step explanation:

If the 2 smallest sides of a triangle add up to be larger than the longest side, then the sides can create a triangle.

Step-by-step explanation:

(45 x 5) + (45 x 4.5) = 427.5

Part A.

Both of them are partly correct. It is an absolute function, so for negative x's, y's are decreasing. For positive x's, y 's are increasing

They are nonlinear too

f(x)=|x|

because every y is positive even when the x values drop to negative. Therefore, and absolute function has to be used.

We know that the perimeter of a rectangle is equivalent to twice the width plus twice the length.

Since the length is 18 more then the width, we can rewrite

l

as

Plug in that in place of

l

and plug in 244 for the perimeter, and you can solve for the width.

If the real size stays the same but the blueprint gets larger, then the scale decreases.

Answer:

See below

Step-by-step explanation:

By the Triangle Inequality Theorem, if given side lengths [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex], where [tex]c[/tex] is the longest side, then [tex]a+b\geq c[/tex]

Problem A

This set of side lengths creates a triangle since [tex]2+6\geq7[/tex]

Problem B

This set of side lengths creates a triangle since [tex]3+3\geq 3[/tex], which is known as  an equilateral triangle since all of its side lengths are equal to each other

Problem C

This set of side lengths creates a triangle since [tex]5+7\geq 12[/tex]

Answer:

x = 50°

Step-by-step explanation:

triangles add to 180 degrees

180 = 110 + 20 + x

180 = 130 + x

-130

x = 50°

Answer:

50°

Explanation

Since we know that a triangle is made up of [tex]180[/tex]° we can make an equation,

[tex]x+110+20=180[/tex]

solve it and we get that

[tex]x=50[/tex]°

Answer:

3/8

Step-by-step explanation:

We already know that 3/4 of the cookies are not chocolate chips, and half of those remaining cookies are peanut butter. We have to divide the fraction 3/4 in half.

We would actually write it as "3/4 * 1/2" because 1/2 is the reciprocal (fraction flipped upside-down) of 2 (which is what we would've divided it by to get halves). 3/4 * 1/2 = 3/8

Answer:

Part A: 4x is the expression you would use. The variable "x" represents the number of deserts she would make.

Part B: 4x=24 is the equation you would use.

4x=24

Step 1 is to divide 4 on both sides. 4x/4 is x and 24/4 is 6. The new equation is x=6

Heather can make 6 deserts.

Step-by-step explanation:

Trust me!!! Have a nice day.

A) an expression with a variable that represents the amount of strawberries Heather needs for the desserts is,

⇒ 4x

B) There are 6 dessert she can make.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Heather is planning a dessert display.

And, She needs 4 ounces of strawberries for each dessert.

Let x represent number of dessert.

Hence, an expression with a variable that represents the amount of strawberries Heather needs for the desserts is,

⇒ 4x

And, If Heather has 24 ounces of strawberries

Then, Number of desserts is.

4x = 24

x = 6

Thus,

A) an expression with a variable that represents the amount of strawberries Heather needs for the desserts is,

⇒ 4x

B) There are 6 dessert she can make.
