Hello!
You have to find what a and b are
3a + 4a = 14
b + 6b = 21
Lets do a first
3a + 4a = 14
Combine like terms
7a = 14
Divide both sides by 7
a = 2
Now lets do b
b + 6b = 21
Combine like terms
7b = 21
Divide both sides by 7
b = 3
Put a and b into the third equation
7( 2 + 3) =
Do what is in parenthesis first
7(5) =
Multiply
35
The answer is 35
Hope this helps!
The inequalities is given by x + y ≤ 120, 4.75x + 7.5y > 690 and y ≥ 80. A possible solution is selling 10 tacos and 100 burritos
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.
Let x represent the number of tacos and y represent the number of burritos sold, hence:
x + y ≤ 120 (1)
Also:
4.75x + 7.5y > 690 (2)
and:
y ≥ 80 (3)
The inequalities is given by x + y ≤ 120, 4.75x + 7.5y > 690 and y ≥ 80. A possible solution is selling 10 tacos and 100 burritos

<h3>What is The Golden Notebook?</h3>
The Golden Notebook is a 1962 book by Doris Lessing, a British author. It investigates mental and societal breakdown, much like her two succeeding books, which Margaret Drabble referred to as Lessing's "inner space fiction" in The Oxford Companion to English Literature. In addition to an extensive investigation of communism and the Communist Party in England from the 1930s to the 1950s, the novel also examines the nascent sexual revolution and women's liberation movements. It also contains anti-war and anti-Stalinist undertones. The Golden Notebook was listed among the top 100 English-language books published since 1923 by TIME magazine in 2005. Other languages that it has been translated into include French, Polish, Italian, Swedish, Hungarian, and Hebrew.
