Answer:
Step-by-step explanation:
Equations
7x + 3y = 4z
<em>Second equation</em>
x + y = z Multiply the entire equation by 4
4[x + y = z] Now distribute the 4 through the equation
4x + 4y = 4z Both equations = 4z. Equate the lefts.
<em>Third equation </em>
7x+3y = 4x + 4y Subtract 3y from both sides
7x + 3y -3y = 4x + 4y -3y
7x = y + 4x Subtract 4x from both sides
7x - 4x = y + 4x - 4x Combine
3x = y
Answer: 3x = y

Answer:
He used about 15 gallons
Step-by-step explanation: if he drove 617.3 miles and he gets 41 miles per gallon, then we can use the formula 41x=617.3 to solve this formula, we would divide 617.3 by 41 to isolate x. 617.3 divided by 41 is equal to 15 and therefore x = 15
The required inequality is: x≤7
Step-by-step explanation:
The words have to be considered and observed properly to write an inequality.
At most means, that the value cannot exceed 7.
So,
Let x be a number
Then
A number is at most 7 will be written as:
as the value of x cannot exceed 7.
The required inequality is: x≤7
