Answer:

a=4

Step-by-step explanation:

Add like terms. You get 7a-6=3a+10. Subtract 3a from 7a and get 4a. Add 6 to both sides and get 16. After this, divide by 4.

allsm [11]

Answer:

There is no solution to the problem

Step-by-step explanation:

In order to find the solutions to the problem you can write the situation in an algebraic form.

You have that a number is equal to twice a smaller number plus 3. This can be written as follow:

x=2y+3      (1)

where x is the number and y is the smaller number

Furthermore, the same number x is equal to twice the sum of the smaller number and 1, which can be written as follow:

x=2(y+1)     (2)

To find the solution you equal the equation (1) with (2), and you solve for y:

2y+3=2y+1

3=1

You obtain an inconsistency, hence, the situation of the problem does not have solution

2a+6b=100<br> what is 5a+15b=?
algol [13]

Answer:

Step-by-step explanation:Simplifying

2a + 6b = 100

Solving

2a + 6b = 100

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-6b' to each side of the equation.

2a + 6b + -6b = 100 + -6b

Combine like terms: 6b + -6b = 0

2a + 0 = 100 + -6b

2a = 100 + -6b

Divide each side by '2'.

a = 50 + -3b

Simplifying

a = 50 + -3b

podryga [215]

By applying the definition of difference, we find that the <em>average daily maximum</em> temperature in Syracuse is 26.55 °C higher than the <em>average daily minimum</em> temperature.

<h3>What is the difference between the average daily maximum temperature and the average daily minimum temperature?</h3>

Herein we must find the difference bewteen the two temperatures, defined as the subtraction of the <em>minimum</em> temperature from the <em>maximum</em> temperature:

x = 21.85 °C - (- 4.7 °C)

x = 26.55 °C

By applying the definition of difference, we find that the <em>average daily maximum</em> temperature in Syracuse is 26.55 °C higher than the <em>average daily minimum</em> temperature.
