If 5a+b=14 then a = what<br> explain how you got it pls
Trava [24]

Answer:

a = \frac{14 - b}{5}

Step-by-step explanation:

The rule to know and follow is:

You can add, subtract, multiply or divide by anything so long as the same thing is done to both sides of the equals sign;

5a + b = 14

If we want to get: "a = ...", then we use the rule to isolate the variable a on one side of the equation;

Firstly, we subtract b from both sides:

5a + b - b = 14 - b

5a = 14 - b

Then, divide both sides by 5:

\frac{5a}{5} = \frac{14 - b}{5} \\\\ a = \frac{14 - b}{5}

I keep getting several answers, and I’m not sure how to solve this ? Help me pleaseee!!
algol [13]

Answer:

Perimeter= 44.2 inches

Area= 70 inches squared

Step-by-step explanation:

Perimeter- Add all your sides together (10+ 17.2+2+3+7+5=44.2)

Area- 1/2bh (b=base, h=height)

Your base is the bottom of the triangle, so 2+7+5=14.

14 is your base

Your height is the 10

1/2 *14*10

1/2 of 14 is 7

7*10= 70

Don't forget to write inches squared or it will be wrong

Hope this helps :)
