Answer:

Hence, we get the equation on elimination as:

10b=60

( Also a= -1 and b=6)

Step-by-step explanation:

We have to use the elimination method to solve the following system of equation with variables a and b:

5a+5b=25 -------(1)

-5a+5b=35-------(2)

Clearly on adding equation (1) to (2) we get:

5a+5b=25

-5a+5b=35

---------------------------

0+10b=60

i.e. 10b=60 is the equation that we obtain and on solving this we obtain:

b=6 ( since on dividing both side of the equality by 10)

Also, on putting value of b in equation (1) we obtain the value of a as:

5a+5×6=25

5a+30=25

5a=25-30

5a=-5

Hence, a= -1.

Sally designs web pages. She charges $140 per web page. She also needs to pay

dolphi86 [110]

You will take 140 times 5 since that is the amount she made so you times it buy the price she earns then after you do that subtract it buy 650 since that is what you have to pay
140 x 5 = 700
700 - 650 = 50
so she made a profit of 50

A PAIR OF JEANS MARKED AT R450 IS SOLD AT DISCOUNT OF 25%.

Stolb23 [73]

Original price is the jeans = Rs450

Discount = 25%

Discount amount

= 25% of 450

= 25%(450)

= 25/100 × 450

= 25/10 × 45

= 5/2 × 45

= 225/2

= Rs112.5

Price after discount

= original price - discount amount

= 450 - 112.5

= Rs337.5

Pls answer quickly, this is due today !!!!!!

Answer:

Step-by-step explanation:

Dear Mrs.Rappa,

I don't know much about this but i do know that saving accounts are risky and she should just set up a checking. Because it's proven that you'll take the risk of losing value in your money. And you take a risk, but to help you more i need to know about what the 5% 7 means. if i do know what it's means, but the 5% is good, it's compound interest which means you get more money on that interest It grows, but as far as the 7 goes, IDK. but the saving %"s are good like yay money, but she takes the risks. So why the risk is there is because of the stock market, and also because the bank takes other clients money for them to pay other client's. So a risk in 7yrs.

Sincerely,

First name Last name Here

Im kinda confused on this. i need help.

Given :-

A graph is given to us .

To Find :-

The equation in slope intercept form .

Answer :-

From the given graph , we can see that the line passes through y axis at (0,5) . So the y intercept is 5 . And the slope of the line is 5/2 = 2.5 . So ,

$\sf\longrightarrow$ y intercept = 5 .

$\sf\longrightarrow$ slope = 5/2 .

Now here we can use the slope intercept form as ,

$\sf\longrightarrow$ y = mx + c

$\sf\longrightarrow$ y = 5/2x + 5

Hence the required answer is y = 5/2x + 5.
