Solve the equation: -8(2a-1)=36

SashulF [63]

The solution to the given equation is $\frac{-7}{4}$ .

<h3>What is an expression?</h3>

Expression is a finite combination of symbols that is well-formed according to rules that depend on the context. An expression is a combination of numbers, variables, or a combination of numbers and variables, and symbols and it is connected by the sign of equal.

We have,

Expression -8(2a - 1) = 36

So,

Now,

To get the solution to this expression,

i.e.

-8(2a - 1) = 36

Rewrite it as,

i.e.

Opening Brackets,

We get,

-16a + 8 = 36

Now,

Taking variable terms on one side and other terms on another side,

We get,

-16a = 36 - 8

On solving we get,

-16a = 28

i.e.

a = $\frac{-28}{16} = \frac{-7}{4}$

So,

The solution to the given equation is $\frac{-7}{4}$ .

Hence, we can say that the solution to the given equation is $\frac{-7}{4}$ .

The sum of two numbers is 90. Their difference is 18. Find the numbers.

Naddik [55]

Answer:

36 & 54

Step-by-step explanation:

By Question :-

Sum of numbers = 90 .
Difference of numbers = 18 .

Let :-

First Number be x .
Second number be y .

According to 1st condition :-

$: \implies$ x + y = 90

According to 2nd condition :-

$: \implies$ x - y = 18

Adding the equations :-

$: \implies$ 2x = 18 + 90

$: \implies$ 2x = 108

$: \implies$ x = 54

Therefore :-

$: \implies$ First number = 54

$: \implies$ Second number = 36

Talja [164]

I think the answer is 25 miles.
6+4+.7x= 27.50
10+.70x= 27.50
.70x= 17.50
Divide both sides by .7 and the answer is 25.
