Step-by-step explanation:

=  \frac{3 \times 2}{4 \times 5}

Solve the following system of equations by linear combination: 5x 2y = 14 y = x – 7
natta225 [31]
I would use subsitution
y=x-7
sub x-7 for every x
5x+2(x-7)=14
5x+2x-14=14
add 14 to both sides
7x=28
divide both sides by 7
x=4
sub
y=x-7
y=4-7
y=-3

x=4
y=-3

Sierra left $4.50 as a tip for a waiter. This was 18% of the bill before the tip. How much was her total bill before the tip? En
IrinaVladis [17]

Answer: $20.5

Step-by-step explanation:

Let x  denotes the amount for total bill.

We are given that ,  Sierra left $4.50 as a tip for a waiter.

This was 18% of the bill before the tip.

We can write 18% = 0.18. [To convert percent into decimal we divide it by 100.]

Then, the tip amount = 0.18 x Total bill

\Rightarrow\ 4.5=0.18x\\\\\Rightarrow\ x=\dfrac{4.5}{0.18}=25

So, the total bill amount = $25

Hence, her total bill before the tip= Total bill amount - Tip amount

= $25- $4.50=$20.5

Thus ,her total bill before the tip= $20.5

How do you rewrite this problem in slope-intercept form
Sergio039 [100]

Solution

-6x - 3y = 9              Add 6x to both sides

-6x + 6x - 3y = 9 + 6x

-3y = 9 + 6x             Or more conventionally

-3y = 6x + 9             Divide by - 3

y = 6x/-3 + 9/-3

y = - 2x - 3
