The answer is a. the first step is to divide the whole bottom equation by -1 because x can’t be negative. you then plug in y + 9 into the first equation to solve. so the equation would be (y + 9) + y = 11. you do this because in substitution you plug in one of the equations into the other equation. you then get 2y + 9= 11. you would next subtract 9 to both sides which leaves you with 2y= 2, divide by both sides, y = 1. you then plug the why value into the first equation to figure out the value for x. so it would be x + 1 = 11, subtract 1, x equals 10.
sorry this was hard to explain! hope this helps!
The 5 number that would round to 360 are 359,358,357,356, and 355 would all round up to 360 and 361,362,363,364 would all round down to 360
Answer:
The answer is -(x-3)
Step-by-step explanation:
It can be written as a negative number so it can be divided/cut :
3 - x = -x + 3
= -(x+3)
Answer:
(∞,-5)
Step-by-step explanation:
For a line to have a slope of 0, it has to be horizontal.
Any point that has a y value of -5 could form a horizontal line along with (0,-5).
Answer:
12/7 bag of flour is required to make 3 batches of cookies
Step-by-step explanation:
From the question;
2/7 bag of flour makes 1/2 of a batch of cookies
x bag of flour will make 3 batches of cookies
Mathematically, we cross multiply
2/7 * 3 = 1/2 * x
6/7 = x/2
2 * 6 = 7 * x
12 = 7x
x = 12/7 bag of flour
