Answer:
The digits in the tens place increase by one from each number to the next.
Step-by-step explanation:
When you count by tens, all the numbers end in zero. For example, if you are counting ,"ten, twenty, thirty, …," the numbers are
10
20
30
40
etc.
The digits in the tens place increase by 1 from each number to the next.
This is the same as in ordinary counting: 1, 2, 3, 4, …
That's the pattern.
Answer:
JL = 68
Step-by-step explanation:
JM = ML
Hence, 3x + 4 = 5x - 16
Subtract 3x from both sides
4 = 2x - 16
Add 16 to both sides
20 = 2x
Divide both sides by 2
10 = x
Now we want to find JL
Note that JL = JM + ML
JM = 3x + 4 and x = 10
Substitute 10 for x
3(10) + 4
Multiply
30 + 4
Add
JM = 34
Because JM = ML
We simply multiply 34 times 2 to find the length of JL
34 * 2 = 68
JL = 68
AVERAGE between 90 and 100%
means not including 90 and 100% but not including 90 or 100%
average=(sum of values in set)/(how many values in the set)
so
4 exams, so there are 4 values
average=(sum)/4
the sum is the known+unknwon
sum=76+99+86+x
so
90<span><</span>average and average <span><</span>100
or
90<span><</span>average<span><</span>100
lets say average=a
a=sum/number
a=(76+99+86+x)/4
90<(76+99+86+x)/4<100
90<(76+99+86+x)/4 and (76+99+86+x)/4<100
solve each for x and find intersection
90<span><</span>(76+99+86+x)/4
times 4 both sides
360<span><</span>261+x
minus 261 both sides
99<span><</span>x
(76+99+86+x)/4<u><</u>100
times 4 both sides
261+x<u><</u>400
minus 261 both sides
x<u><</u>139
so
99<u><</u>x<u><</u>139
since max score is 100
99<u><</u>x<u><</u>100
interval notaion is
[99,100]
answer is 2nd one
