Answer:
The w in w² + 5·w → Variable
The 2 in w² + 5·w → Exponent
The 5 in w² + 5·w → Coefficient
Step-by-step explanation:
1) The variable in an equation are the unknown values of the equation, and the values of the variables that meet the requirements of the equality are known as the solutions of the equations;
2) The exponent is the power to which a number or a variable is raised. It shows the number of times the variable or number multiples itself
3) The coefficient is the factor multiplying the variable in an equation or expression.
Answer:
5x - 3
Step-by-step explanation:
Add like terms: (4x + x) + (-6 + 3) = 5x - 3
Answer:
- 35 grams of 11.43% solution
Step-by-step explanation:
The end solution has same volume as initial volumes of mixture.
The concentration of solution is calculated as below
- 10*0.15 + 25*0.1 = 4 g
- 4 / 35*100% = 11.43% (rounded)
Answer:
344 1/4
Step-by-step explanation:
Responder:
12
Explicación paso a paso:
Dado que:
Kilogramo total de mandarina = 9 kg
Tamaño de cada distribución = 3/4 de kilo
Número de mallas:
Kilogramo / tamaño total por distribución
9 kg ÷ 3/4 kg
9 * 4/3
= (9 * 4) / 3
= 36/3
= 12
