Add the two equations, 0.75x+1.5y=40 and −1.5x−1.5y=−60 , to find the value of x .
sergij07 [2.7K]

The value of x in the equation is 26.7

<h3>How to solve an equation?</h3>

0.75x + 1.5y = 40

−1.5x − 1.5y = −60

add both equation to eliminate y .

Therefore,

−1.5x + 0.75x = -0.75x

1.5y + (- 1.5y) = 0

40 + (-60) = -20

Hence,

-0.75x  = - 20

divide both sides by -0.75

-0.75x / -0/75 = - 20 / -0.75

x = - 20 / -0.75

x = 26.6666666667

x = 26.7

nancy started the year with $425 in the bank and is saving $25 a week. Seamus started the year with $875 and is spending $15 a w
Goryan [66]

They will have same amount in 45 weeks.

Step-by-step explanation:

Given,

Starting amount of Nancy = $425

Per week saving = $25

Let,

x represent the number of weeks.

N(x) = 25x+425

Starting amount of Seamus = $875

Per week saving = $15

S(x) = 15x+875

For same amount;

N(x) = S(x)

25x+425=15x=875\\25x-15x=875-425\\10x=450

Dividing both sides by 10

\frac{10x}{10}=\frac{450}{10}\\x=45

They will have same amount in 45 weeks.

A triangle has three different integer side lengths and a perimeter of 20 units. What is the max length of any one side?
Troyanec [42]
X + x+1 + x + 2 = 20
3x + 3 = 20
3x = 17 but can't start with x = 6 because 6+7+8 > 20,
so have start with 5 + 6 + 7 = 18 are the 3 sides.

40 POINTS!!!!<br> what is the coordinates of x+y=6?
il63 [147K]
Here, your equation is x + y = 6

In order to calculate coordinates, put x = 0, 
0 + y = 6, 
y = 6

Now, put y = 0, x + 0 = 6
x = 6

So, Your Coordinates would be: (0, 6) & (6, 0)

Hope this helps!
