Answer:No
Step-by-step explanation:
Given system of equation is:
2x + 3 = y
2x + y = 15
To check whether (2,7) is solution to this system or not, we will put x=2 and y=7 in both equations.
Putting x=2 and y=7 in Eqn 1
2(2) + 3 = 7
4 + 3 = 7
7 = 7
Thus the ordered pair satisfies the equation
Putting x=2 and y=7 in Eqn 2
2(2) + 7 = 15
4 + 7 = 15
11 ≠ 15
The ordered pair do not satisfy the second equation.
Hence,
(2,7) is not a solution to the given system of equations.
If sara leaves her bin out and a gallon of water is 3 litres
let the water in the bin be x
x=3 litres
the answer is 3 liters

24% of 38 = (1 - 24/100) × 38 = 28,88 = 29
24 % ←→ 29
x% ←→ 10
x = 10 × 24 ÷ 29
x = 8,27586
x = 8 %
ANSWER 8%
Answer:
J(-5,2), A(-5,4), and N(-1,1)
Step-by-step explanation:
We are given two variables, distance and volume of gas required to reach the distance.
We are then asked to find the rate of consumption in miles per gallon.
The approach is simply to divide distance by the volume to get the rate per unit gallon.
This means that for each gallon consumed, 24 miles are covered.
24 mpg
