What is the distance between the points (–8, –2) and (–7, –2)? A.
1

B.
6

C.
10

D.
15

Answers

Answer 1

Answer: easy, since the y coordinat didn't change, y didn't move
only x moved
we just see how far x moved
-8 to -7
that is 1 distance

or ou could use distance formula

the distance between the points
(x1,y1) ad (x2,y2) is
D= $\sqrt{(x2-x1)^(2)+(y2-y1)^(2)}$
points are
(-8,-2) and (-7,-2)
D= $\sqrt{(-7-(-8))^(2)+(-2-(-2))^(2)}$
D= $\sqrt{(1)^(2)+(0)^(2)}$
D= $√(1+0)$
D= $√(1)$
D=1

Asia walks from her house to Alexis's house,a distance of 2 miles, in 70 minutes, how far has she traveled in 35 minutes?

Answers

2 miles in 70 minutes

1 mile in 35 minutes

70/2 = 35
2/2 = 1

Therefore, she travels half way to Alexis's house in 35 minutes. In other words, she walks 1 mile in 35 minutes.

Lets look at the info we have-

2 miles in 70 min

Questions asking?

How far has she traveled in 35 min?

To solve this we have to find out first how many min it takes her to walk 1 mile. To do this we will divide:-

70 ÷ 2 = 35

So, Asia has walked 1 mile in 35 minutes.

A perfume manufacturer uses 0.875 pounds of rose petals to make each bottle of perfume. How many pounds of rose petals would be needed to make 86 bottles of perume???

Answers

To solve this problem
Let X be pounds of rose petals needed.
ATQ
0.875 pounds of rose petals are in 1 bottle.
So, 0.875 / 1 = X / 86
( because we have to find how many petals {in pounds}are there in 86 perfume bottles )
cross muliplying both side.
0.875 * 86 = X
75.25 = X
So, there are 75.25 pounds of petals in 86 perfume bottles.

86 bottles of perfume* (0.875 pounds of rose petals/ 1 bottle of perfume)= 75.25 pounds of rose petals.

The correct answer is 75.25 pounds of rose petals~

What is the value of x when -25(x - 4) = -55(x - 10) ?

Answers

The given equation is solved to give value of x as 15.

How to solve a linear equation?

A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.

The given equation is as below,

-25(x - 4) = -55(x - 10)

It can be simplified as follows,

-25(x - 4) = -55(x - 10)

=> -25x + 100 = -55x + 550

=> -25x + 55x = 550 - 100

=> 30x = 450

=> x = 15

Hence, the value of x for the given equation is 15.

#SPJ2

Simplify both sides of the equation

-25(x-4)=-55(x-10)

(-25)(x) + (-25)(-4)=(-55)(x) + (-55) (-10)

Distribute

-25x+100=-55x+550

Add 55x to both sides

-25x+100+55x=-55x+550+55x

30x+100-100=550-100

subtract 100 from both sides

30x+100-100=550-100

30x=450

divide both sides by 30

30x/30=450/30

x= 15

The value of x is 15

Describe the mental math steps you would use to find 7(42)

Answers

Answer:

$7* 42 = 294$

Step-by-step explanation:

Distributive property of multiplication over addition:

When a number is multiplied to a sum of two numbers then it can be multiplied to the numbers individually and then add the two products,

It can be written as:

$a* (b+c) = (a* b) + (a* c)$

Similarly, we can use this property to find the product of $7* 42$

$7* 42\n= 7* (40+2)\n= (7* 40) + (7* 2)\n= 280 + 14\n= 294$

The product of 7 and 42 is 294.

You would find 7*40 7*4=28
So 7*40=280 (just add a zero)
7*2=14
The answer would be 280+14=294
