Chandler is three more than 5 times as many years old as his sister Kayla
In 9 years he will be twice as old as she will be then, How old is Chandler
now?
A.2
B.11
C.13
D.15
E.22
Answer:
Chandler is C 13 years old
Step-by-step explanation:
5x2=10
10+3=13
Makeing the answer C
Now Chandler's age will be 22 now. Then the correct option is E.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Chandler is three more than 5 times as many years old as his sister Kayla. In 9 years he will be twice as old as she will be.
Then the equation will be
C = 3 + 5K ...1
C + 9 = 2(K + 9) ...2
From equations 1 and 2, we have
3 + 5K + 9 = 2(K + 9)
5K - 2K = 18 - 12
K = 2
The Chandler's age will be
C = 3 + 5K
C = 3 + 5 x 2
C = 13
Now Chandler's age will be 22 now. Then the correct option is E.

PLEASE HELP IM TIMES AND EXPLAIN STEP BY STEP , so using substitution method solve the system of equations , y = 2x + 8 and y = 4x - 2 , whoever answers step by step gets brainliest
Answer:
y= 2x + 8 , y = 4x - 2
2x + 8 = 4x - 2
8 = 2x - 2
10 = 2x
5 = x
Step-by-step explanation:
Answer:
x = 5
Step-by-step explanation:
y = 2x + 8
substitute the y in the other expression with this expression (you can do it vise versa too but i chose this because it was first)
2x + 8 = 4x - 2
goal is to isolate the variable
add 2 to both sides (this cancels out the -2 on the right side)
2x + 8 + 2 = 4x - 2 + 2
2x + 10 = 4x + 0
2x + 10 = 4x
subtract -2x from both sides (cancels out the 2x on the left side)
2x - 2x + 10 = 4x - 2x
0x + 10 = 2x
10 = 2x
divide both sides by 2 (cancels out the 2 on the right side)
10 ÷ 2 = 2x ÷ 2
5 = 1x
5 = x
variable is isolated and tells us that x = 5
5/10 x 9/12 will give brainliest if correct

In the state of New Mexico, 85% of the land is above 4,000 feet in elevation.
Which fraction is equivalent to 85%?
A 4
5
B
100
17
20
1
85
Answer: 17/20
==============================
Work Shown:
x% = x/100
85% = 85/100
85% = (17*5)/(20*5)
85% = 17/20
------------
You could also go through all the answer choices to see what works and what doesn't.
For instance, 4/5 = 0.80 = 80%, so that is a non-answer.
But 17/20 = 0.85 = 85% which is the answer.
