A shelf is the shape of a triangle. Find the angles of the triangle if the measure of the angle are in the ratio x:x:4x.show work please

Answers

Answer 1

Answer: The value of x is 30; hence 4x is equal to 120. That is because the sum of the angles of a triangle is 180. So, add x, x and 4x together, you get 6x. Divide 180 by 6, you get 30. Hope this helped!

A collection of 33 coins having dimes quarters and nickels, there are 3 times more nickels then dimes and half the amount of dimes as nickels, all of the coins equal $3.30 how many of each coin?

Answers

Answer:

Each coins are quarters of 6, nickels of 18 and the dimes of 9.

Step-by-step explanation:

There is a mistake in question.

The question must be:

A collection of 33 coins having dimes quarters and nickels, there are 3 times as many nickels as quarters, and one-half as many dimes as nickels, all of the coins equal $3.30 how many coins of each kind are there?

Now, to find the number coins of each.

Let the quarters be $x$ .

Nickels be $3x$ .

And the dimes be $(3x)/(2)$ .

So, the total collection of coins are:

$x+3x+(3x)/(2) =33.$

On adding the fractions we get:

$(2x+6x+3x)/(2) =33$

$(11x)/(2) =33$

Multiplying both sides by 2 we get:

$11x=66$

Dividing both sides by 11 we get:

$x=6.$

Thus, quarters = 6.

Nickels = $3x=3* 6=18.$

Dimes = $(3x)/(2) =(3* 6)/(2) =(18)/(2)=9 .$

Therefore, each coins are quarters of 6, nickels of 18 and the dimes of 9.

Answer:

x > 6

Step-by-step explanation:

-5 > 19 - 3x + (-6)

Combine like terms.

-5 > 13 - 3x

Subtract 13 from both sides.

-18 > -3x

Divide both sides by -3.

6 < x

Flip this around. x > 6

What is 3×24= as a mixed number?

Answers

Set up the division problem in long division format Move the decimal the same amount of places in both numbers until the divisor is a whole number. Divide 24 by 3 to get 8. Place this next digit in the quotient on top of the division symbol. Multiply the newest quotient digit (8)by the divisor 3. Subtract 24 from 24 to get 0. The result of division of 23 over 4 so the answer is 8.

Divide the numerator by the denominator. Write the mixed number in this way: The quotient (answer) is the whole-number part (3). The remainder of the improper fraction is the numerator (4).
