Answer 1

Answer: The answer would be D.

Answer 2

Answer:

Answer:

5 - 2x

Step-by-step explanation:

Translating words to numbers can be tricky.

Here it says: "5 decreased by twice a number." So you have to imagine-- I started with Five things. Then there was a decrease --twice some variable.

5 take away twice something translates to

5 - 2x

Tricky, because most algebra expressions are written with variables first, then the constants. You could rewrite this expression as

-2x + 5

Multiply.–3 • 7 =

A.
–21

B.
–11

C.
11

D.
21

Answers

The answer is -21 because take 3 times 7 which is 21 and sense there's a negative and positive you would make 21 negative.

When you multiply a negative and a positive you will get a negative answer so 3*7 is 21 so -3 * 7 is -21

greta makes a slice through a three-dimensional object parallel to the base the cross section is a circle. What three dimensional shapes might greta have cut?

Answers

Answer:

A. Cylinder.

C. Cone.

Step-by-step explanation:

Notice that the cross section is parallel to the base. So, if the cross section is a circle, then the base is also a circle.

Then, we just need to find all figures that have a circle at the bottom. The figures are a cylinder and a cone.

Therefore, the right answers are A and C.

Answer:

A. Cylinder

C. Cone

Step-by-step explanation:

Both a cylinder and a cone are three dimensional shapes that contain a circle as the base. If a cross section is made parallel to the base, that means that it should have the same shape as the base. Since a pyramid and cube both have straight edges, it would not be possible to form a circle from a parallel cut to the base, so the only options are cylinder and cone.

2/3 of 24 bananas = how many bananas

Answers

To find out what two thirds of 24 bananas will be, you first need todivided 24 by 3. The answer to this will be 8, so we therefore know that8 in one third. To find two thirds, simply times one third (8) by two,so 8*2 is 16. From this we now know that two thirds of 24 bananas willbe 16.
