Answer:
-29
Step-by-step explanation:
replace the variables with the numbers provided. m = -4 so replace the m in the equation with -4:
3 - (-4)n
same thing with the n. n=-8 so replace the n in the equation with -8:
3 - (-4)(-8)
and then all you have to do after that is solve it using PEMDAS
multiply -4 and -8 first:
3 - 32
then solve 3-32 and you end up with -29.

find the estimates of x^2-x-2=3
Answers
Answer:
[tex]x=\frac{1+\sqrt{21}}{2}\approx 2.79\\or\ x=\frac{1-\sqrt{21}}{2}\approx -1.79[/tex]
Step-by-step explanation:
Given
Quadratic equation is
[tex]x^2-x-2=3\\x^2-x-5=0[/tex]
Roots of the quadratic equation [tex]ax^2+bx+c=0[/tex] are
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\[/tex]
So, for the given equation roots are
[tex]x=\frac{1\pm\sqrt{(-1)^2-4(1)(-5)}}{2\cdot 1}\\x=\frac{1\pm\sqrt{21}}{2}\\so, x=\frac{1+\sqrt{21}}{2}\approx 2.79\\or\ x=\frac{1-\sqrt{21}}{2}\approx -1.79[/tex]

find the measure of the missing angles
Answers
Answer:
b=80
c=80
Step-by-step explanation:
the angle opposite to the 100 degree angle is congruent to it
same goes for b and c
so far we have 2 angles that measure 100 degrees 100+100=200
the sum of the 4 angles is 360
360-200=160
160/2=80=b=c
because of where 100 is you can make a line where b and c are. a straight line is 180 so you subtract from 100 to get 80
The cost of a daily rental car is as follows: The initial fee is $69.99 for the car, and it costs $0.30 per mile. If John initially pays $200.00 before taxes and does not want to exceed that amount, how many miles can he drive?
x ≥ 433 miles
x = 450 miles
x ≥ 450 miles
x ≤ 433 miles
Answers
x [tex]\geq[/tex] 433
explanation:
let m equal miles
0.30m + 69.99 = 200
-69.99 -69.99
0.30m = 130. 01
130.01 / 0.30 = 433. 36...
but we're gonna round it to 433
so 433 miles

A ton might weigh 2000 pounds. How many six grades might weigh 2000 pounds?
Answers
Answer:
25
Step-by-step explanation:
An average 6th grader weight 80 pounds and 2000/80 is 25
25 six graders might weigh 2000 pounds, considering the average weight of a six grader is 80 pounds.
Average is the mean value of the data. It is a measure of central tendency.
Given the following information:
A ton might weigh 2000 pounds.
We need to find the total number of six graders require to collectively weigh 2000 pounds.
Let the total number of six graders require = x
Consider the average weight of a six grader is 80 pounds.
Total weight= average weight of a six grader x total number of six graders x
Total weight= 80x
2000=80x
To calculate the value of x, divide 80 both the sides.
2000/80=80x/80
25=x
x=25
Thus, 25 six graders might weigh 2000 pounds.

Work out

Pls work this out. It’s urgent!
Answers
firsty remember OF= MULTIPLY
NOW we can calculate this easily
here the equation is given
2/5×60. u can solve this in given ways below….…..
1……….
u can simply divided 60 by 5. which is equal to 12. and now the equation remain 2×12 . & it's equal to 24. which is our answer.
2……….
u can write 2/5 in decimals by dividing this . so 2/5 is equal to 0.4
and now u r left with 0.4×60
so after multiplying it comes 24.0
and that is equal to 24. (because after decimal zeros has no value)
3……….
and u also can multiply 2 by 60 . it occurs 120 then devide it by 5 . the answer comes 24.

45 marbles in 9 bags; 150 marbles in 36 bags
is this rate proportional?
Answers
Answer:
No, the rate is not proportional.
Step-by-step explanation:
If there are 45 marbles in 9 bags, we can assume that there are 5 marbles in each bag.
Going by that rate, we can do 5 * 36 = 180, NOT 150.
Thus, the rate is not proportional.
Another way to solve would be to do 45/9 and 150/36. If the rate is proportional, the answer for both should be the same.
However, 45/9=5 and 150/36=4.16666666667.
Those two answers are NOT equal.
Thus, the rate is not proportional.
