Answer:
The final score of Roger is 22.
Step-by-step explanation:
The final score (F) of Roger is given by:
[tex] F = 5R - 2W [/tex]
Where R is the right answers and W is the wrong answers
Since he gets 6 questions correct (R = 6) and 4 question wrong (W = 4) we have:
[tex] F = 5R - 2W = 5*6 - 2*4 = 22 [/tex]
Therefore, the final score of Roger is 22.
I hope it helps you!

1. Solve for q:
√3q + 2 = √5
2. solve for d:
4d + 1 = √3
3. Solve for m:
m/√3 - 11 = 4
Answer:
1) q = (sq rt 15 - 2) / 3
2) d = (sq rt 3 - 1) / 4
3) m = 15 * sq rt 3
Step-by-step explanation:
1.√3q + 2 = √5
we bring to the power of 2 each element
(√3q)^2+2^2=√5^2
3q+4=5
3q=4-5
q=1/3
2.
4d+1=√3
we do the same thing
16d^2+1=3
16d^2=2
d^2=2/16
d^2=1/8
d=√1/√8
3.
m/√3 -11=4
first we rationalise by multiplying the first fraction with √3
m√3 /3-11=4
now we can bring to the power of 2
3m^2/9-121=16
3m^2/9=137
m^2/3=137
m^2=411
m=√411

A hummingbird weighed w ounces. One day the hummingbird drank 8 times its weight in water and ate half its weight in food. Which equation can be used to find t, the combined weight of the water and the food, in ounces, that the hummingbird had on this day?
t = w + 8 - 1/2
t = w +8 + 1/2
t = 8w + w/2
t = 2w + 2/8

a. 3,6
b. 6,-3
c. 6,3
d. 3,-6
Answer:
c. (6, 3)
Step-by-step explanation:
subtract
3x + 6y = 36
3x - 6y = 0
12y = 36, y = 3
3x + 6(3) = 36
3x + 18 = 36
3x = 18, x = 6
x = 6, y = 3

Answer:
The first term should be positive
She did not distribute the -4 properly
She added [tex]\frac{2}{7}[/tex] to negative -4 instead of multiplying
Step-by-step explanation:
In order to tell where she is wrong we should solve the question our selves. we are going to get the following......
[tex]-4(-3x + \frac{2}{7})= -4(-3x) + (-4)(\frac{2}{7} )= 12x - \frac{8}{7}[/tex]
So now we see that the three things she did wrong are.
The first term should be positive
She did not distribute the -4 properly
She added [tex]\frac{2}{7}[/tex] to negative -4 instead of multiplying
Hope this helps :)
Answer:
1, 4
Step-by-step explanation:
1. the product of two negatives are positive and they didn't do that, so yes.
2. the second term should NOT be positive, so they are correct on that.
3. they distributed the -4 correctly but added wrong, so they are correct on that.
4. -4+2/7=3 5/7 2/6(-4)=-4/3. They added instead of multiplying, so they are wrong.
5. they did simplify completely. they just did it wrong.

rocky thinks of an odd integer adds the next two consecutive integer which of these could be the sum
Answer:
C
Step-by-step explanation:
1. Let x be the odd integer. Let y be the sum.
x + (x + 1) + (x + 2) = y
3x + 3 = y
Adding two consecutive integers to an odd integer will result in an even integer.
So, you can eliminate choices B and D since they are odd.
Lastly, plug in choices A and C for y and choose the answer that makes x an integer.
Choice C would give you the correct result.
3x + 3 = 44562
3x = 44559
x = 14853
The odd integer and the two consecutive integers whose sum is 44,562 are 14,853, 14,854, and 14,855 respectively.
Let
Small odd integer = xNext consecutive integer = x + 1Next two consecutive integer = x + 2Sum of consecutive integers = 44,562Sum:
x + (x + 1) + (x + 2) = 44,562
x + x + 1 + x + 2 = 44, 562
3x + 3 = 44,562
Subtract 3 from both sides3x = 44,562 - 3
3x = 44,559
divide both sides by 3x = 44,559 / 3
x = 14,853
Therefore, the odd integer and the two consecutive integers whose sum is 44,562 are 14,853, 14,854, and 14,855 respectively.
