So, first of all you have to identify the two equations which are: y=7x-8 and y=5x-2. after identifying the two equation you can choose one of them to start with. I chose the first one and I'll use substitution method, which means I'll pug in numbers in the unknown variables to find the value of x. Y=7x-8, I'll substitute the value of y in the equation that I chose and plug in the value of the second equation. Y=7x-8 --> 5x-2=7x-8 (this is our new equation). After that I'll combine like terms. -2+8=7x-5x --> 6=2x --> 6/2=x --> 3=x. So x=3 and that's the answer using substitution method. If the two points are graphed, they will intersect at the point (3,13). To see where the intersection of the line we can use a calculator to make it faster. So we plug in the points of the two lines in the calculator we graph and find the intersection point.
3 ways
1 - 6 packs of 6 cookies (6*6 = 36)
2 - 2 packs of 18 cookies (2*18 = 36)
3 - 3 packs of 6 cookies and 1 pack of 18 cookies (3*6 = 18 + 18 = 36)
If the diameter is 18 inches, the radius is 9 inches. The formula for circumference is 2*pi*r, so it would be 2*3.14*9, so the circumference is 56.52 inches. But rounded to the nearest inch, it is 57 inches.
Answer:
There is no solution for this set of equations.
The sum of two numbers can not have two different solutions.
Answer:
There will be 11 mozzarellas and 6 pizza rolls
Step-by-step explanation:
80x+90x=1740,5x+x=6x,
80(6)+90x=1740,1740-480=990,
90x=990,x=11
