Answer:
Missing Number) 55
Property being used) Distributive
Step-by-step explanation:
To find the missing number, just plug in reasonable numbers from the other equation. It is distributive because the 55 is being distributed into everything that is inside the parentheses. If you need more help, comment and I'll be more than glad to assist you! :P
Answer:
14x-11
Step-by-step explanation:
f(x) = 2x − 5
g(x) = 7x − 3
(f(g(x))=
Substitute g(x) into f(x) for every x
f(g(x) = 2 (g(x) -5
=2 (7x-3) -5
Distribute
=14x-6 -5
=14x-11

The value of the constant a will the system of linear equations 6x-5y=3 and 3x+ay=1 have no solution is -5/2
<h3>System of equation</h3>
For a system of equation to have no solution, the expression on both sides must be different.
Given the system of equation
6x-5y=3 and
3x+ay=1
For the equations to have no solution, the a1/a2= b1/b2
Substitute
6/3 = -5/a
Cross multiply
2 = -5/a
a= -5/2
Hence the value of the constant a will the system of linear equations 6x-5y=3 and 3x+ay=1 have no solution is -5/2

Answer:
45
Step-by-step explanation:
Let us assume the Bags of oranges be x
Now the cost price is 2500x
Sale price N = 90,000
Loss =20%
As we know that
Cost price= selling price × 100/ 100-percentage loss
= 90,000 × 100/ 100- 20
= 90,000 × 100 /80
Cost price= 112,500
Now
The Number of bags of oranges is
= 112,500 ÷ 2500
= 45
