Answer:
∠ G = 121°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
x + 3x + 25 + x - 5 = 180 , that is
5x + 20 = 180 ( subtract 20 from both sides )
5x = 160 ( divide both sides by 5 )
x = 32
Thus
∠ G = 3x + 25 = 3(32) + 25 = 96 + 25 = 121°
Answer:
121

Step-by-step explanation:
- 1/5 of 5x is -1 or just -x and -1/5 of 20 is -4. Then the other one is-1/4 of 4 is -x and -1/4 of -28 is 7. Now combine like terms so -x + -x is -2x and 7+ -4 or 7-4 is 3

Answer the following:
A) Which function has the higher initial amount of bacteria? g(x) or f(x)
B) Which function has the greater amount of bacteria after two days? g(x) or f(x)
Answers
Answer:
A. The function f(x) has the higher initial amount of bacteria.
B. The function g(x) has the higher amount of bacteria after two days.
Step-by-step explanation:
The given function is
The graph of g(x) passing through the points (0,1000) and (1,3000). So the initial value is 1000 and the growth factor is 3.
The function g(x) is
Part A:
Substitute x=0, to find the initial blue of the functions.
Since 2000>1000, therefore the function f(x) has the higher initial amount of bacteria.
Part B:
Substitute x=2, to find the amount of bacteria after two days.
Since 8000<9000, therefore the function g(x) has the higher amount of bacteria after two days.
x + y = 8
What number should the equation x + y = 8 be multiplied by to eliminate y?
Answers
x + y = 8
when multiplying an equation every term is multiplied
eg:
x + y = 8 //multiply by 3
3*x + 3*y = 3*8
3x + 3y = 24
in elimination method two equations are added when there are oposite coefficients of chosen variable
5x + 2y = 30 coefficient of y is 2
x + y = 8 //multiply by -2
5x + 2y = 30
-2x - 2y = -16
-------------------- sum
5x-2x+2y-2y=30-16
3x = 14 //y has been eliminated (elimination method)
answer: the number is -2
1) Multiply the 2nd row by 5
5x+2y=30
5x+5y=40
2) Subtract the 2nd row from the 1st row
−3y=−10
3) Solve for the variable y in the above equation
⇒ Solve for y
−3y=−10
⇒ Divide both sides by −3
y=−10 / −3
⇒ Simplify 10 / −3 to −10 / 3
y=10 / 3
4) Substitute y=10 / 3 into any of the two equations above.Let's pick the first equation 5x+2y=30.
5x+2× 10 / 3 = 30
5) Solve for x in the above equation
(there are more steps but the answer is below)
x=14 / 3
Therefore,
x=14 / 3
y=10 / 3

represent q=# of quarters
d=# of dimes
so barney gets dimes so replace barney with d and betty with q
barney get 5 more coins than betty
d=5+q
total=5.05=0.25q+0.10d since each is worth 0.25 and 0.10 so we have
d=5+q and 5.05=0.25q+0.10d
subsitue (5+q) for d
5.05=0.25q+0.10(5+q)
distribute
5.05=0.25q+0.50+0.10q
add like terms
5.05=0.35q+0.50
subtract 0.50 from both sides
4.55=0.35q
divide both sides by 0.35
13=q
subsitute
d=5+q
d=5+13
d=18
barney got 18 coins and betty got 13 coins
