Step-by-step explanation:
Let assume that
Cost of 1 burger = $ x
Cost of 1 doughnuts = $ y
According to statement, 9 burgers and 1 doughnut cost $ 31.30
According to statement again, 3 doughnuts and 6 burgers cost $ 26.70
On substituting the value of y from equation (1), we get
So,
Cost of 2 burgers = 3.2 × 2 = <u>$ 6.4</u>
Answer:
y= -5x + 2
Step-by-step explanation:
the slope is heading downwards, and down five units for each one across (hence m=5) and the y-intercept is 2 (hence the 2)
Answer:
7x - 5y = -5 this is the standard form
the answer is option e. *answer needs to be 20 characters long this should do :)
Answer:
D. x=4
Step-by-step explanation:
We can solve this with the Pythagorean Theorem for the right triangle that we can see (which is half of the triangle).
The bottom length is 3 and the hypotenuse is 5.
The Pythagorean Theorem is a²+b²=c².
We can plug this in:
3²+x²=5²
9+x²=25
x²=16
x=4
