Given that a = ( − 6 7 ) and b = ( − 1 − 3 ) . If a − b = ( x y ) , work out the values of x and y .

Answers

Answer 1

Answer:

x = -5 , y = 10

Step-by-step explanation:

As given ,

a = ( x₁ , y₁ ) = ( -6, 7)

b = ( x₂ , y₂ ) = (-1, -3)

For a -b = ( x₁ - x₂ , y₁ - y₂ )

            = ( -6 - (-1) , 7 - (-3) )

            = ( -6 + 1 , 7 + 3 )

            = ( -5 , 10 )

⇒ a - b = ( -5, 10 ) = ( x, y)

∴ we get

x = -5 , y = 10

Stephanie and Jose both want to buy a skateboard. Stephanie has already saved $25 and plans to save $5 a week until she can buy the skateboard. Jose has $16 and plans to save $8 a week. How many weeks will it take for them to have the same amount of money and how much will they have?


(Also if u can pls type out ur answer like "10 weeks and $100" hehe)

Answers

Answer: 3 weeks and $40

Step-by-step explanation:

Let the number or weeks taken for them to have same amount be represented by x.

The information given in the question can be presented as an equation as:

Stephanie = 25 + 5x

Jose = 16 + 8x

We then equate them together

25 + 5x = 16 + 8x

25 - 16 = 8x - 5x

3x = 9

x = 9/3 = 3

The number of weeks is 3

The amount of money that they'll have will be:

= 25 + 5x

= 25 + 5(3)

= 25 + 15 = $40

Write and solve a proportion to answer the question. what number a is 0.4% of 40​

Answers

Answer:

.16

Step-by-step explanation:

So, we're looking for 0.4% of 40.  First, let's convert 0.4% to a decimal.  Since a percent is really just PARTS of one hundred, this decimal really means 0.4/100.  0.4 divided by 100 is 0.004.  Next, we need to figure out how to solve this problem!  To find a percent of a number, just multiply the percent (in decimal form) by the number!  So, we need to answer 0.004*40, which equals 0.16.

Answer: 0.16

Sara hina and arsalan has rupees 930 if Sara has 7 more than Hina and arsalan has 3 times what sara has how much do they have

Answers

Answer:

Step-by-step explanation:

Let us represent:

Number of rupees that:

Sara has = x

Hina = y

Arsalan = z

Sara,Hina and arsalan has rupees 930

x + y + z = 930..... Equation 1

if Sara has 7 more than Hina

x = y + 7

y = x - 7

Arsalan has 3 times what sara has

z = 3x

We substitute x - 7 for y and 3x for z in Equation 1

x + y + z = 930..... Equation 1

x + x - 7 + 3x = 930

5x - 7 = 930

5x = 930 + 7

5x = 937
