How do you answer this?

Answers

$(m^(-2))^5=m^(-2\cdot5)=m^(-10)$

$x^2+3x-10=\nx^2+5x-2x-10=\nx(x+5)-2(x+5)=\n(x-2)(x+5)$

(m*-2)*5 simplifies to m*-10.

Jenny is on the local swim team for the summer and has swim practice four days per week. The schedule is the same each day. The team swims in the morning and then again for 2 hours in the evening. If she swims 20 hours per week, how long does she swim each morning?

Answers

Answer:

Number of hours Jenny swims each morning = 3 hours

Step-by-step explanation:

Let Jenny swims 'x' hours in the morning each day.

She swims 2 hours in the evening too.

Total hours she swims each day = (x + 2) hours

If her team swims 4 hours per week then number of hours she swims = 4(x + 2)

If she swims 20 hours in a week then,

4(x + 2) = 20

(x + 2) = 5

x = 5 - 2

x = 3 hours

Therefore, Jenny swims 3 hours each morning.

The local pre-school ordered all new bicycles and tricycles for the new school year. Each bicycle and tricycle is shipped in its own box. Oddly, the manufacturer shipped all of the wheels in a separate box. If there are 16 boxes of bicycles/tricycles total and 45 wheels total, how many tricycles were ordered?please don't just put an answer i need an explanation too

Answers

there are 16 boxes total, and 45 wheels total.

we know that each bicycle/tricycle is in it's own box.
i'm going to use the variable "b" for bicycle and "t" for tricycle

b + t = 16
(because b is the amount of bicycles and t is the amount of tricycles)

now we know that there are 45 wheels total.
there are 2 wheels for a bicycle and 3 wheels for a tricycle

2b + 3t = 45

now we have a system of equations
b + t = 16
2b + 3t = 45

You can solve this multiple ways, but I'm going to use substitution.
b + t = 16 can also be written as b = 16 - t (if you subtract both sides by t)
then we can substitute this b = 16 - t into the other equations

2(16 - t) + 3t = 45

32 - 2t + 3t = 45
32 + t = 45
t = 13

now you can plug that back into the original equations

b + 13 = 16
b = 3

2b + 3(13) = 45
2b + 39 = 45
2b = 6
b = 3

Write an expression using the distributive property that can be used to find the quotient of 36 ÷ 3

Answers

something like 36÷3 = (3)÷3=1 and (6)÷3=3 you put 1 and 3 together to make 13

Final answer:

The solution to the given mathematical problem is found by using thedistributive property to break down 36 into its component parts (30 and 6), then dividing each part by 3, yielding the answer of 12.

Explanation:

The question is framing a scenario where we need to use the distributive property to simplify a division operation. The distributive property deals with multiplying a number by a sum or difference, in essence 'distributing' the multiplication over addition or subtraction.

So the division 36 ÷ 3 could be set up using the distributive property like (3×10) + (3×2) by breaking down 36 into a sum like 30 + 6.

So, 36 ÷ 3 = (3 x 10 + 2) ÷ 3 Applying the distributive property, we distribute the division operation over the addition. = (30 ÷ 3 + 6 ÷ 3) = 10 + 2 = 12
