Answer:
-8,-7,-6,-5
Step-by-step explanation:
to start pick 4 variables lets say x, y, z, and a then remember that consecutive means one after another so x = x ,y = x + 1, z = x + 2, and a = x + 3. x + y + z + a = -26 so x + x + 1 + x + 2 + x + 3 = 26 then solve for x. finally go back and solve for the other variables.
Answer:
The new width is 3 in.
Step-by-step explanation:
We can use the ratio of w/h, the origal width and height should have the same ratio as the new width and height.
<u>12 </u>= <u>x</u>
16 4
Then solve for x:
x = 4 (12/16)
x = 3
To check:
12/16 = 3/4
3/4 = 3/4
Answer: false
Step-by-step explanation:
Answer:
(3, -3)
Step-by-step explanation:
When asked to solve by elimination, you put them on top of one another, like you're going to add it.
10x + 7y = 9
-4x - 7y = 9
See that 7y? You can cancel those out because one is negative, and one is positive. So those are gone. You finish adding the rest of the numbers as usual and solve for x.
6x = 18
x = 3
Take x, and plug it into either equation to find y.
10(3) + 7y = 9
7y = -21
y = -3
(3, -3)
Hope this helped!
