Overnight the temperature went from 39*F to -5*F. What is the difference in temperature?
Answers
Explanation: Since the new temperature is a negative number and the old was positive, you add them together. However instead of (-5) +39 (which the answer would be 35), you would write 5 +39 because -5 is 5 spaces away from 0. You can also check by using the equation 39 -44. You would get the answer -5, proving that the answer is indeed -44 degrees.

y=2x-3
y=2x+3
Since the both expressions 2x-3 and 2x+3 are equal to y, set them equal to each other forming an equation in x.
2x-3=2x+3
Cancel equal terms on both sides of the equation

9. What is the value to the solution for the system of equations y = -5X-9 and y = 2x + 5.
Answers
9514 1404 393
Answer:
(x, y) = (-2, 1)
Step-by-step explanation:
Equate the two expressions for y.
-5x -9 = 2x +5
-14 = 7x . . . . . . . .add 5x-5
-2 = x . . . . . . . . . divide by 7
Then ...
y = 2(-2) +5 = 1
The solution is (x, y) = (-2, 1).
A chemist has three different acid solutions. The first acid solution contains 15 % acid, the second contains 35 % and the third contains 65 % . He wants to use all three solutions to obtain a mixture of 72 liters containing 45 % acid, using 2 times as much of the 65 % solution as the 35 % solution. How many liters of each solution should be used?
Answers
Answer:
18 liters 15% acid
18 liters 35% acid
36 liters 65% acid
Step-by-step explanation:
Let's say x is the volume of 15% acid, y is the volume of 35% acid, and z is the volume of 65% acid.
x + y + z = 72
z = 2y
The amounts of acid add up to the final amount.
0.15x + 0.35y + 0.65z = 0.45 (72)
Substitute the expression for z into both equations.
x + y + 2y = 72
0.15x + 0.35y + 0.65 (2y) = 0.45 (72)
Simplify:
x + 3y = 72
0.15x + 1.65y = 32.4
Solve for x in the first equation, then substitute into the second.
x = 72 − 3y
0.15 (72 − 3y) + 1.65y = 32.4
Solve for y.
10.8 − 0.45y + 1.65y = 32.4
1.2y = 21.6
y = 18
Now find x and z.
x = 72 − 3y = 18
z = 2y = 36
18 liters 15% acid, 18 liters 35% acid and 36 liters 65% acid should be used.
What is percentage?Percentage is a measurement to find the value of a given number out of a hundred.
Let x is the volume of 15% acid, y is the volume of 35% acid, and z is the volume of 65% acid.
Given that, the total mixture is 72 liters,
Implies that,
x + y + z = 72
Also,65% solution is used two times as 35% solution is used.
z = 2y
The amounts of acid add up to the final amount.
0.15x + 0.35y + 0.65z = 0.45 (72)
Substitute the value of z here,
0.15x + 0.35y + 0.65 (2y) = 0.45 (72)
Simplify
x + 3y = 72
0.15x + 1.65y = 32.4
Solve for x in the first equation, then substitute into the second.
x = 72 − 3y
0.15 (72 − 3y) + 1.65y = 32.4
Solve for y.
10.8 − 0.45y + 1.65y = 32.4
1.2y = 21.6
y = 18
Now find x and z.
x = 72 − 3y = 18
z = 2y = 36
18 liters 15% acid, 18 liters 35% acid and 36 liters 65% acid should be used.

Lianne is saving to buy a DVD player that costs 2 1\2 times her weekly allowance. If she spends 3\4 of her allowance on other things, how long will she take to save the money for the DVD player?
Answers
Answer:
She will take 10 weeks to save the money for the DVD player
Step-by-step explanation:
Let w = Lianne's weekly allowance.
The DVD player costs 2 1/2 times her weekly allowance, thus
DVD cost = 5/2w
She gets w every week but spends 3/4w on other things, thus the remaining money is
Weekly savings =w - 3/4w = 1/4w
To know the number of weeks needed, we divide the DVD cost by the weekly savings:
[tex]\displaystyle N = \frac{\frac{5}{2}}{\frac{1}{4}}[/tex]
Operating:
[tex]\displaystyle N = \frac{5}{2}*\frac{4}{1}[/tex]
N = 10
She will take 10 weeks to save the money for the DVD player

2. 50%
3. Assuming the photo is a rectangle, the answer would be 90 degrees on every angle (in a dilation, angle measurements are congruent).
Step-by-step explanation:
1. The long side is clearly the 6 cm side. multiply it by 1.5x (150%) and you get 9.
2. 2 is 50% of 4 and 3 is 50% of 6.
