- 5y + 8x = -18
5y + 2x = 58
х=
y =
Answers
Answer:
x = 4 and y = 10
Step-by-step explanation:
-5y + 8x = -18
5y + 2x = 58
First you will want to get rid of y from both equations, so you add both equations together.
You will get 10x = 40, then subtract 10 from both sides and you get x = 4.
Now substitute x as 4 in any of the equations to get y.
-5y + 32 = -18
-5y = -50
y= 10
Answer:
x = 4
y = 10

does 9/20 and 18/30 form a proportion
Answers
Answer:
No, they don't.
Step-by-step explanation:
I'm going to divide 18 by 9 and 30 by 20. If the quotients are the same, then we do have a proportion.
18 ÷ 9 = 2
30 ÷ 20 = 1.5
The quotients aren't the same. Same thing if you convert the fractions to decimals:
9 ÷ 20 = 0.45
18 ÷ 30 = 0.6
This means the two values do NOT form a proportion.
Hope this helps! Have a great day!
Answer:
No.
Step-by-step explanation:
9/20=18/30
9*30=20*18
120=360

14d - 22 + 5d = 12d - 8
Answers
Answer:
d = 2
Step-by-step explanation:
14d - 22 +5d = 12d - 8
19d -22 = 12d - 8
+22 +22
19d = 12d + 14
-12d -12d
7d = 14
/7 /7
d = 2
Answer:
d = 2
Step-by-step explanation:
Simplifying
14d + -22 + 5d = 12d + -8
Reorder the terms:
-22 + 14d + 5d = 12d + -8
Combine like terms: 14d + 5d = 19d
-22 + 19d = 12d + -8
Reorder the terms:
-22 + 19d = -8 + 12d
Solving
-22 + 19d = -8 + 12d
Solving for variable 'd'.
Move all terms containing d to the left, all other terms to the right.
Add '-12d' to each side of the equation.
-22 + 19d + -12d = -8 + 12d + -12d
Combine like terms: 19d + -12d = 7d
-22 + 7d = -8 + 12d + -12d
Combine like terms: 12d + -12d = 0
-22 + 7d = -8 + 0
-22 + 7d = -8
Add '22' to each side of the equation.
-22 + 22 + 7d = -8 + 22
Combine like terms: -22 + 22 = 0
0 + 7d = -8 + 22
7d = -8 + 22
Combine like terms: -8 + 22 = 14
7d = 14
Divide each side by '7'.
d = 2
Simplifying
d = 2

2x - 10 = 3x + 21 2. Add 10 on both sides
2x = 3x + 31 3. Subtract 3x on both sides
-x = 31 4. Divide by -1

Answer:
yes, no, no, yes
Step-by-step explanation:
Plug in each point into both equations to see which ones fit.
For the first point, (4,1) it works for both equations.
1=-2( 4 ) + 9, 1= -8 + 9, 1=1
4( 4 )+2( 1 )=18, 16 + 2 = 18, 18 = 18
Do it for the rest of the points and plug them in and you get,
no for (5,-3) because -1 does not equal to -3
no for (6,0) because -3 does not equal to 0
(-5,19) is yes because 19=19 and 18=18

2. Four big water bottles can hold 8 gallons of water. How much water can ten big water bottles
hold?
Answers
Answer:
16 1/2 gallons of water.
Step-by-step explanation:
Since 4 bottles can hold 8 gallons, and you need to know how much 10 can hold, you can multiply 4 and 8 times 2 so you get 8 and 16, and then if you choose 10 instead of 8 instead you would get the result of 10 bottles being able to hold 16 1/2 gallons of water.
