X represents elga’s age
x+14+x=98
combine like terms
2x+14=98
subtract 14 from both sides
2x=84
divide both sides by 2 to isolate the variable (x)
x=42
elga is 42 years old.
if alvin is 14 years older than elga, and elga is 42, then alvin is 56 years old. 42+56=98

Round 939,515 to the nearest ten.
Effectus [21]

Answer: 939,520

Step-by-step explanation: To round 939,515 to the nearest ten, we first find the digit in the rounding place which in this case is the 1 in tens place.

Next, we look at the digit to the right of of the 1 which in this case is 5.

According to the rules of rounding, since the digit to the right of the rounding place is greater than or equal to 5, we round up.

This means that we add 1 to the digit that's in the rounding place so 1 will become 2 and we change all the digits that appear to the right of the rounding place to 0.

So 939,515 rounded to the nearest 10 is 939,520.

Dafna11 [192]

Answer:

0.25feet

Step-by-step explanation:

The equation is not well written. Let the equation of the height be modelled as;

h = -16d²+8d+4

The velocity of the ball is zero at its maximum height.

Velocity = change in displacement/time

v = dh/dd

Differentiate

v = -32d+8

Since dh/dd = v = 0

0 = -32d+8

Add 32d to both sides

0+32d = 8

32d = 8

Divide both sides by 32

32d/32 = 8/32

d = 1/4

d = 0.25feet

Hence the maximum height of the tennis ball is 0.25feet

Note that the modeled equation was assumed. You can apply the same calculation to any equation given
