65 x 7 with distributive property
Can someone please explain

Answers

Answer:

$65* 7=455$

Step-by-step explanation:

Given : Expression $65* 7$

To find : Solve expression with distributive property?

Solution :

Distributive property, $(a+b)c=ac+bc$

To apply property we break, 65=60+5

$65* 7=(60+5)* 7$

$65* 7=60* 7+5* 7$

$65* 7=420+35$

$65* 7=455$

Therefore, $65* 7=455$

7(60 + 5)
The seven carries over to both values.
420 + 35
420 + 35 is simply 455.

A) A
B) A
C)A
D) B
Reason I know this is because if we look at the x number in all of these, if 2 are the same (like 2,6 and 2,4) then its a non function.
But if none of the x =the same value its a function.
Same goes for B
C
and now D, is a non function because out X's:
3
5
5
7
5 was repeated so it's a nonfunction.
Got it?

a rock climber that is 0.74 mile above sea level ascends 0.18 mile and then descends 0.8 mile which represents the location of the rock climber compared to sea level

Answers

0.12 miles above sea level.

0.74 + 0.18 = 0.92

0.92 - 0.8 = 0.12

Ascend= + Descend= - .74+.18=.92 .92-.8= .1 2 .12 is the answer

Carly is traveling to visit family. She drives x miles on the first day and y miles on the second day for a total of 800 miles. What are the domain and range of this relationship?

Answers

Answer:

The domain and range of this relationship is (-∞,∞) and (-∞,∞) respectively.

Step-by-step explanation:

We are given that Carly is traveling to visit family.

She drive distance on first day = x

She drive distance on second day = y

We are also given that Carly is travelling a total of 800 miles.

So,x+y=800

We are supposed to find domain and range of this relationship.

y=800-x

Domain : (-∞,∞)

Range:(-∞,∞)

Hence the domain and range of this relationship is (-∞,∞) and (-∞,∞) respectively.

Answer:

domain: 0 ≤ x ≤ 800

range: 0 ≤ y ≤ 800

What is the expanded form of 876 million

Answers

the expanded form is: 800,000,000+70,000,000+ 6,000,000

First lets write 876 million out:-

876, 000, 000

Now lets write it in expanded form:-

876, 000, 000

800,000,000 + 70,000,000 + 6,000,000 + 0 + 0 + 0 + 0 + 0 + 0 = 876, 000, 000

So, 876 million in expanded form is:-

800,000,000 + 70,000,000 + 6,000,000 + 0 + 0 + 0 + 0 + 0 + 0 =
