Given x:y:z = 7:2:5 and the value of

Cari nilai bagi x+y+z
A 14
B. 126
C. 210
D. 232
Answers
Answer:
x + y + z = 123
Step-by-step explanation:
x:y:z = 7:2:5
Let x = 7a, y = 2a, z = 5a
Since x - z = 18
Therefore,
7a - 5a = 18
2a + 18
a = 18/2
a = 9
7a = 7*9 = 63
2a = 2*9= 15
5a = 5*9 = 45
x + y + z = 63 + 15 + 45
x + y + z = 123

Max scored 71 and 65 on his first
two tests in Biology 101. What is the
lowest he must score on the third
test to get an average for the
three tests above 77?
Answers
Answer:
Step-by-step explanation:
If he scored 71 and 65 and needs an average above 77, you took the average needed of 77 and times by 3 since you will have 3 test total. 3*77=231. Take the 231- what you already have which is 136, to get 95. He will need a score of at least 95 to average the 77. 71+65+95=231 231/3= 77
So, x≥95. X is the next test. It would need to be greater than or equal to 95.

Answers
Answer:
its C got it on E2020
Step-by-step explanation:
A line does not extend from a side of a triangle to form angle 2. Then the correct option is C.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
The exterior angle of a triangle is almost always equal to the addition of the interior and opposing interior angles. The term "external angle property" refers to this feature.
Choose the triangle in which angle 2 is not an exterior angle.
The external angle can be made when the line is extended and the angle is formed outside the triangle, which is known as the exterior angle.
A line does not extend from a side of a triangle to form angle 2. Then the correct option is C.

The general formula for nth term of given sequence is:
[tex]G_n = 54 . (\frac{1}{3})^{n-1}[/tex]
Step-by-step explanation:
Given sequence is:
54,18,6.....
In order to write the general formula of a sequence, first of all the common ratio has to be found. Common ratio is the ratio between consecutive terms of a geometric sequence.
[tex]Here\\a_1 = 54\\a_2 = 18\\a_3 = 6\\And\\r = \frac{a_2}{a_1} = \frac{18}{54} = \frac{1}{3} \\r = \frac{a_3}{a_2} = \frac{6}{18} = \frac{1}{3}[/tex]
The general formula is:
[tex]G_n = A_1 (r)^{n-1}[/tex]
Putting the values of a1 and r
[tex]G_n = 54 . (\frac{1}{3})^{n-1}[/tex]
Hence,
The general formula for nth term of given sequence is:
[tex]G_n = 54 . (\frac{1}{3})^{n-1}[/tex]

In the function f(x)=2x+5, f(11)=___?
A 27
B 22
C 18
D 11
Answers
Answer:
A
Step-by-step explanation:
We have the function:
[tex]f(x)=2x+5[/tex]
And we want to find f(11).
So, we can substitute 11 for our function and evaluate. Therefore:
[tex]f(11)=2(11)+5[/tex]
Evaluate:
[tex]f(11)=22+5=27[/tex]
Hence, our answer is A.

Multiply second equation by 2
4x + 14y = 42
4x + 5y = 24
Now subtract both
9y = 18
Y = 2
Plug 2 into equation to solve for x
4x + 5(2) = 24
4x = 14
x = 3.5, y = 2
Answer:
x = 3.5, y = 2
Step-by-step explanation:
This is a system of equations.
Original equations:
[tex]4x+5y=24\\3x+7y=21[/tex]
Substitute y and solve for x:
→ [tex]y=\frac{24-4x}{5} \\2x+7y=21[/tex]
Substitute the value for y and simplify:
→ [tex]2x+\frac{7(24-4x)}{5} =21[/tex]
→ [tex]2x + \frac{(168 - 28x)}{5}=21[/tex]
Multiply by 5 on both sides
→ [tex]10x + 168-28x = 105[/tex]
Simplify → [tex]-18x = -63[/tex]
→ [tex]x = 3.5[/tex]
Plug in the value for x into either equation:
→ [tex]4*3.5 + 5y=24[/tex]
→ [tex]14+5y=24[/tex]
→ [tex]5y=10[/tex]
→ [tex]y=2[/tex]

Marissa bought 4 cans of corn and 8 cans of green beans for a total of $7.00. Bob bought 8 cans of corn and 7 cans of green beans for a total of $8.60. Determine how much each can green beans cost.
Answers
Step-by-step explanation:
1 can of corn = c
1 can of green beans = b
Marissa-> 4c+8b=7
Bob-> 8c+7b=8.60
form a simultaneous equation:
4c+8b=7
8c+7b=8.60
find a common coefficient, e.g. make the number of cans of corn that Marissa has, equal to the number of cans of corn that Bob has, so you would multiply the top equation by 2, so both people have 8 cans of corn
8c+16b=14
8c+7b=8.60
now you can cancel out the cans of corn, and subtract the second equation from the first one, so you would get:
16b-7b=9b
14-8.60= 5.4
so, 9b=5.4, and b= 0.6
so 1 can of green beans would cost $0.60
