Jeff as a collection of hockey cards. His brother Steve had 10 more cards than Jeff. Steve gave Jeff all of his cards. Jeff ended up with 992 cards. How many cards did Jeff start with?
Answer: 491 cards
Step-by-step explanation:
Given
Steve had 10 more cards than Jeff
Suppose Jeff has x cards
So, steve has x+10 cards
Steve handover his cards to Jeff
Now, Jeff has x+x+10=2x+10 cards
It must be equal to 992
[tex]\Rightarrow 2x+10=992\\\Rightarrow 2x=982\\\Rightarrow x=491\ \text{cards}[/tex]
Jeff started with 491 cards

Enter your solution without units below. 5cm 5cm 4cm 12cm 6cm
Answer: if ur looking 4 the surface area, then its 216 cm2.
Step-by-step explanation:
a= 1/2 b h
a= 1/2 (6) (4)
a= 12
12x2=24
a=lw
a= 12(5)
a= 60
60x2= 120
a=lw
a= 6(12)
a= 72
24+72+120= 216
Chang knows one side of a triangle is 13 cm. Which set of two sides is possible for the lengths of the other two sides of this triangle?
Answer:
Choice D - 8cm and 9cm.
Explanation:
The other sides are not greater than 13.
A: 5 + 8 = 13
B: 6 + 7 = 13
C: 7 + 2 = 9
However, D is greater than 13 and is the correct answer.
D: 8 + 8 = 16.

The ages of the racers in a bicycle motocross race are 14, 22, 20, 25, 26, 17, 21, 30, 27, 25, 14, and 29. The 30-year-old drops out of the race and is replaced with a 15-year-old. How are the mean, median, and mode of the ages affected?
Answer:
The mean is decreased by 1.25.
The mode remains the same.
The median is decreased by 2 .
Step-by-step explanation:
Re arranging the data 14, 22, 20, 25, 26, 17, 21, 30, 27, 25, 14, and 29.
Gives
14, 14,17,20, 21, 22, 25,25, 26, 27, 29,30,
Now the mean = 14, +14,+17, +20, +21,+ 22, +25,+25,+ 26, + 27, +29,+30/12
Mean= 270/12=22.5
The Mode ( the repeated value) = 14,25
Median ( the average of middle value) = 22+25/2= 23.5
When 30 is replaced is by 15
Now the mean = 14, +14, +15,+17, +20, +21,+ 22, +25,+25,+ 26, + 27, +29/12
The Mean becomes = 255/12=21.25
The Mode ( the repeated value) = 14,25
Median ( the average of the middle value) = 21+22/2= 21.5
The difference between the 2 means is = 22.5- 21.25= 1.25
The mode remains the same.
The median is decreased by 2 .
The mean is decreased by 1.25 which is more than 50 % of the value obtained between the ratio of the omitted and added value (30/15=) i.e. 2

Solve the system of equations -3x+7y=-18 and 4x-4y=8 by combining the equations
Answer:
(-4, -3)
Step-by-step explanation:
Using elimination by addition and subtraction works best here.
Suppose we decide to eliminate x temporarily. To do this, we multipy the first row by 4, obtaining
-12x + 28y = -72
4x - 4y = 8
Next, multiply the second row by 3, obtaining the "equivalent system"
-12x + 28y = -72
12x - 12y = 24
Combining these equations, column by column, we get:
16y = -48. So y = -3.
Now let's find x. Substitute -3 for y in the second equation:
4x - 4(-3) = 8, or
4x + 12 = 8, or
4x = 8 - 12 = -4. This tells us that x = -4.
The solution is thus (-4, -3).

Anyone good at geometry proofs? Help with math please. Thank you!
Answer and Step-by-step explanation:
1. Given
This part is given at the beginning of the problem.
2. Corresponding Angles Postulate
Because the lines are parallel, these two angles will be congruent by the corresponding angles postulate.
3. Same-Side Interior Angles Theorem
The same-side interior angles theorem has it so that the angles within parallel lines will add up to 180.
4. Substitution
We can use substitution here because we already determined that the measure of angle UTY is congruent to the measure of angle HGY.
I hope this helps!
#teamtrees #PAW (Plant And Water)
Answer:
Below.
Step-by-step explanation:
m <UTY + m <UTR = 180 degrees ( Angles on a straight line YR)
But m < UTR = m<RWX ( Corresponding angles in the parallel lines SU and VX)
So substituting for m< UTR in the first equation:
m <UTY + m<RWX = 180.
