Answer:
Step-by-step explanation:
hello :
3x − 2y = −9 ...(*)
4x + 3y = 22...(**)
multiply (*) by 3 and(**) by 2 you have : 9x-6y = -27
8x+6y =44
add this equations : 17x = 17 so : x=1
put this value in : 8x+6y=44
8(1)+6y=44
6y=36
y=6
one solution : (1 ; 6)
The answer is 10 hope this helps
Answer:
<em>40 + 5x ≤ 50</em>
Step-by-step explanation:
<u>Inequalities</u>
The maximum weight allowed for checked bags on a particular airline is 50 pounds.
Jennifer has already used up to 32 pounds of clothes and the empty suitcase weighs 8 pounds. This makes a weight of 40 pounds already used.
If five identical gifts of x pounds each are to be included in the suitcase, the total weight is 40 + 5x. And that weight cannot exceed 50 pounds, thus:
40 + 5x ≤ 50
That is the inequality to represent the situation.
Answer:
10
Step-by-step explanation:
The answer is D.4
1/3(30x-12)=36
Multiply the 1/3 by the 30x and -12
You will get
10x-4=36
You move the -4 to the other side but u flip the sign so it will be
10x=36+4
10x=40
Divide 10 by both sides you get
X=4
That’s it!
