Uma wants to buy a video game system for $400. She has $50 and is saving $25 each week. Solve the equation 25w + 50 = 400 to find how many weeks w it will take Uma to save enough to buy the system.

Answers

Answer 1

Answer: Move all terms that don't contain ww to the right side and solve.
w=14

Hope this helps,

kwrob

Answer 2

Answer: First take away fifty from both sides
25w = 350
Divide 25 from both sides
Answer is: w = 14

So, it will take Uma 14 weeks to save enough money to but the video game system.

Hope that helps!!!

If f (x) = 3x + 2 and g(x) = x^2 + 1 which expression is equivalent to ( f o g) (x)

Answers

Answer:

( f o g) (x) = 3x²+5

Step-by-step explanation:

We have given two functions :

f (x) = 3x + 2

g(x) = x² + 1

We have to find ( f o g) (x) =?

( f o g) (x) = (f(g(x))

Putting the values of functions in above formula.

( f o g) (x) = 3(x²+1)+2

( f o g) (x) = 3x²+3+2

Adding like terms,we have

( f o g) (x) = 3x²+5

( f o g) (x) = 3x²+5 is the answer.

Answer: (f o g)(x)= $3x^(2)+5$

Step-by-step explanation:

To solve this problem you must apply the following proccedure:

(f o g)(x) indicates that you must substitute the function g(x) into the function f(x).

Therefore, you have:

(f o g)(x)= $3(x^(2)+1) +2$

Now, you must simplify it, as it is shown below:

Apply the distributive property and add the like terms:

(f o g)(x)= $3x^(2)+3+2$

(f o g)(x)= $3x^(2)+5$

What can be multiplied to get 5 and added to get 4

Answers

It's not possible nothing but 1 times 5 is the only thing that multiplies to 5 and 1+5 doesn't equal 4

spinniong a spiner that has 5 equal sections marked 1-5 and landng on an even number. What your answer im simplest form and finding each probability

Answers

You would have a 40% chance or a 2/5 chance because 5 numbers 1 through 5 would be 1 2 3 4 5 so 2/5 of the numbers are even, but 40% would also be the answer because 20% of 5 is 1, and 40% of 5 is 2. So 2 out of 5 are even so your answer is you have a probability of 40% or 2/5 toland on an even number. Please mark brainliest if this helped

True or false a trapezoid is a polygon, so all polygons are trapezoid. explain.

Answers

False!! A polyhedron is ANY shape with at least three straight sides. A trapezoid is a type of polyhedron.
(A trapezoid is a shape with four sides, only two of them being parallel.)
Hope that helps!!

Yes a trapezoid is a polygon but false because a polygamy is a shape that has 3 or more sides so it could be from a triangle onwards

What is 20% of 120 and how do u get the answer

Answers

20% of 120 is 24.

To find this answer, you need to use the percentage formula (is over of equals the percentage over 100, is/of = p/100).

Plug in the known numbers. You know you need 20%, so plug 20 into the percentage place.

is/of = 20/100

You know the "of," which is 120, so plug that in.

is/120 = 20/100

You don't know the "is," so to find it you need to multiply cross multiply 120 by 20. Then you need to divide your answer by 100 to find your missing value (is).

120 * 20 = 2,400
2,400 / 100 = 24

Multiply 120 by .2 to get 24
