24 cookies 54 cookies
cross multiply
2*54=24x
24x=108
x=4.5
4.5 cups of flour
You add half of the coefficient of x and square it.
What you do on one side,you must do it on the other.
Answer:
B. x
Step-by-step explanation:
-3x+8y=-6
3x-2y=-12
if we add these
-3x+3x+8y-2y=-6-12
6y=-12 so x will be eliminated
Answer
x>21.2
Step-by-step explanation:
7.55x+100>160
-100 on both sides
7.55x>60
/ 7.55 on both sides
x>21.2
That is a bit of a high number, but im pretty sure that I did the math right
> is less than or equal to in this equation bc idk how to make the real sign
Answer:
B. 2x + 4y
Step-by-step explanation:
If x = 4, and y = 7, let's substitute these values for x and y in the equations!
For A, the equation is 2xy. Substitute the values and you have 2(4)(7) which equals 56. This expression is incorrect since the expression doesn't equal 36.
For B, the equation is 2x + 4y. Substitute and you get the equation
2(4) + 4(7) → 8 + 28 = 36.
36 is your desired value, and you get that with the expression 2x + 4y.
