Equation #1:
6-x=2x+18 \\
-x-2x=18-6 \\
-3x=12 \\
x=\frac{12}{-3} \\
x=-4

Equation #2:
5x-10=4x+3 \\
5x-4x=3+10 \\
x=13

-4 is smaller than 13, so the solution to equation #1 is smaller than the solution to equation #2.
The answer is a.

Answer:The Basic Formula

The formula multiplies the area's length in feet by its width in feet and its height in feet. This number is then multiplied by one-third and divided by 27 to convert the answer into cubic yards. To make it clearer, the equation is as follows: (Length (ft) x Width (ft) x Height (ft) x 1/3) / 27.

What is the value of this expression when a=20 5a
Darina [25.2K]

Answer:

100

Step-by-step explanation:


Given :     a=20


To Find :  the value of  expression 5a.

Solution :

We are given the value of 'a' i.e. a=20

Now to find the value of given expression  5a


⇒5a


put a = 20 in the equation


⇒5*20


⇒100


⇒5a = 100


Thus , The value of expression 5a when a = 20 is 100

1.Afla numarul abc,stiind ca abc:15=16 rest 1
mixas84 [53]

Step-by-step explanation:

Ques 1)

abc: 15 = 16 rest 1

that means that if abc is divided by 15 than we get the quotient as 16 and remainder as 1.

Hence using : dividend=divisor×quotient+remainder we have:

abc=15×16+1

Hence, the value of abc is 241.

Ques 2)

a)

486: x = 17

i.e. \dfrac{486}{x}=17

⇒ x=486×17=8262

b)

y: 18 = 35 rest 1

that means when y is divided by 18 we get the quotient as 35 and remainder as 1.

Hence using : dividend=divisor×quotient+remainder we have:

y=35×18+1=631

y=631

c)

730: z = 27 rest 1

that means when 730 is divided by z we get the quotient as 27 and remainder as 1.

Hence using : dividend=divisor×quotient+remainder we have:

730=27z+1

27z=730-1

27z=729

z=27 (dividing both side by 27)

Ques 3)

Let'a' and 'b' denote the two natural numbers such that a is greater than 'b'.

a-b=70----(1)

also when a is divided by b then we get the quotient as 8 and some remainder.

Let the remainder be 'r'.

this means a=8b+r

let us consider r=0.

a=8b

hence from (1) we have

7b=70

b=10 (on dividing both side by 7)

hence a=80.

when r=1,2,3,4,5,6

we do not get a natural number as value for a and b.

also when r=7 we get the value of b=9 and a=79

After r>7 we get the value of b<r such a condition is not possible.
