Answer:
option D
2x − 7(−3x − 17) = 4
Step-by-step explanation:
Given in the question two equations
<h3>Equation 1</h3>
2x - 7y = 4
<h3>Equation 2</h3>
3x + y = -17
Rearranging equation 2 in terms of y
3x + y = -17
y = -17 - 3x
Put this value of y in Equation 1
2x - 7y = 4
2x - 7(-17 - 3x) = 4
So,
If you use the substitution method to solve the following system, new equation will be
<h3>2x - 7(- 3x - 17) = 4 </h3>
Answer:
Step-by-step explanation:
Just divide the larger mass by the smaller.
0.5 / 0.005 = 0.5 / 0.5 * 10^-2 = 1 * 10^2 = 100
It take 100 ants to equal the mass of a grasshopper.

Answer: Value of x = 27
Explanation:
Percy is plotting a coordinate on the graph.
Now the ratio of y-value to x-value is 2 to 3 for each point.
Suppose Value of is 3a and y value is 2a
So, the coordinate of the point is (3a,2a)
Now we find the x value of the coordinate when value of y is 18.
2a is same as 18
2a = 18
a =
a = 9.
Now find the x ordinate
put the value of a=9 into 3a
3a = 3(9) = 27
So the final answer is :
Value of x = 27 when value of y = 18
