What is the solution of the system of equations y=5.69x+25 y=9.49x+6

Answers

Given :

A system of equations y = 5.69x + 25 and y = 9.49x + 6.

To Find :

The solution of the system of equation.

Solution :

Subtracting equation 2 by 1, we get :

y - y = ( 9.49x + 6 ) - ( 5.69x + 25 )

0 = 3.8x - 19

x = 5

Putting value of x in equation 1, we get :

y = (5.69×5) + 25

y = 53.45

Therefore, the solution of the system of equations is ( 5, 53.45 ).

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

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

Answer: w^2 + 15w + 54

Step-by-step explanation:

FOIL = first, outside, inside, last.

First —> multiply first numbers of each parentheses.

Outside —> multiple the OUTSIDE numbers in each parentheses (first number in the first parentheses, second number in the second parentheses.

Inside —> multiply the INSIDE numbers in each parentheses (the second number in the first parentheses, first number in the second parentheses).

Last —> multiply second number of each parentheses.

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.
