Answer:
question 3: 1/3 question 4: 5/7 question 5: 2/3
Answer:
Option A. x = 8
Step-by-step explanation:
Please see attached photo.
From the attached photo,
we shall determine the value of y. This can be obtained by using pythagoras theory as illustrated below:
(√80)² = 8² + y²
80 = 64 + y²
Collect like terms
80 – 64 = y²
16 = y²
Take the square root of both side
y = √16
y = 4
Finally, we shall determine the value of x. This can be obtained as follow:
From the attached photo,
x = 2y
but:
y = 4
Therefore,
x = 2y
x = 2 × 4
x = 8
Total number of units= 3+1
=4
4u=72
1u= 72/4
=18
Cheeseburger= 18x3
=54
Hamburger= 18
After you plug in d and C you will end up with 40 after you solve if you just need the equation it will be -2-4-3+17+32 to simplify further add like terms which will give you -9+49 add those and it’ll be 40
Answer:
Step-by-step explanation:
the y= equation shows how... b/c we can just plug y into the 2nd equation and eliminate y and have one variable, x , to solve for :)
