Answer:
8 marker
Step-by-step explanation:
You would add 10 to 54 and then divide by 8.

1. You need to figure out what 90% is of the total, 70.
2. Do this by multiplying 70 by 90% --> 70*(.9)
3. 90% of 70 is 63. The total number correct is 63.
You can check your work by figuring out what percentage 63 is of 70. 63 divided by 70 (63/70) is .9, or 90%.

If they drive an average of 60 miles per hour the last day it will take them 2.5 hours.
4 hours at 60 miles per hour = 4*60 = 240 miles
6 hours at 65 miles per hour = 6*65 = 390 miles
This is a total of 630 miles. There are 780-630=150 miles left; if they average 60 miles per hour, that would be 150/60 = 2.5 hours.

Multiplicative patterns are the patterns in which when a constant value (apart from zero) is multiplied by a given input value to know the output value.Hence the graphs of multiplicative pattern have in common that they are repetitive for the same value. The multiplicative pattern graph for the above equation is attached below.
What is multiplicative pattern graph?
Multiplicative patterns are the patterns in which when a constant value (apart from zero) is multiplied by a given input value to know the output value. Such patterns are multiplicative pattern as they are repeating the values for variables with the same number.
Let a function of variable x for a line as,
The value for variable will be different for the different values of the variable
. For the given function when the value of
is 0 then
When the value of is 1 then
When the value of is 2 then
when the value of is 3 then
Thus the values for the function is in the form of multiple of four. Such patterns are multiplicative pattern as they are repeating the values for variables with the same number.
Hence, the graphs of multiplicative pattern have in common that they are repetitive for the same value. The multiplicative pattern graph for the above equation is attached below.

Solve for j
Group terms that contain the same variable, and move the constant to the opposite side of the equation
therefore
the answer is
2.25 + (-11j) + (-7.75) + 1.5j = 0.5j + (-1)
-5.5 + (-9.5 j) = 0.5j + (-1)
-5.5 + (-9.5j) + (-0.5j) = -1
-5.5 + (-10j) = -1
-5.5 + 5.5 + (-10j) = -1 + 5.5
-10j = 4.5
-10j/-10 = 4.5/10
j = -0.45 assuming that 7.75 was added to 1.5 j

Answer:
14.5
Step-by-step explanation:
First, let's confirm that total points = total number of games played.
Suppose, if any one of the player wins all the games, then,
total points = 21(1) + 0 = 21 = total number of games
Suppose, all the games end in draw. Then,
21(0.5) + 21(0.5) = 21(0.5 + 0.5) = 21(1) = 21 = total number of games
Suppose, if one player wins in 10 games and the remaining 11 games end in draw, then,
10(1) + 11(0.5 + 0.5) = 10 + 11 = 21 = total number of games
So, in all cases, total points = total number of games played
Now, let x be the points that the loser has.
So, the winner's points should be x + 8.
Total number of games played = 21
Since, total points = total number of games played,
x + (x + 8) = 21
2x + 8 = 21
2x = 21 - 8 = 13
x = 6.5
Winner's points = x + 8 = 6.5 + 8 = 14.5.

The three equivalent ratios are 27/6, 45/10, and 36/8.
Given,
The ratio of right-handed students to left-handed students is 18:4.
We need to find three equivalentratios of 18:4.
What is a ratio?
A ratio is denoted by A:B.
If the ratios are equal we called it proportion.
Example:
2/4 = 16/32 = 6/12
2/4 = 1/2
16/32 = 2/4 = 1/2
6/12 = 1/2
2/4, 16/32, and 6/12 are equivalent ratios and they are in proportion.
We have,
18:4
It can be written as:
= 18/4
Reducing it to the smallest term.
= 2 x 9 / 2 x 2
= 9 / 2
So,
We can have,
27/6, 45/10, and 36/8 as our equivalentratios.
27/6 = 3 x 9 / 3 x 2 = 9/2
45/10 = 5 x 9 / 5 x 2 = 9/2
36/8 = 4 x 9 / 4 x 2 = 9/2
Thus the three equivalent ratios are 27/6, 45/10, and 36/8.
