X/62+89=92 !!!! plz quick

1 answer:

5 0

To solve an algebraic equation, we need to get x by itself. We can start to do that by multiplying each side of the equation by 62 (to remove the denominator of x).

x + 89(62) = 92 * 62

Simplify

x = 92 * 62 - 89 * 62

Now we can factor out 62

x = 62 (92 - 89)

Now we can simplify the parenthesis

x = 62 * 3

x = 186

Think of one leg of a right triangle is 21' and the length of the hypothenuse is 29' what is the length of the other leg

Ksivusya [100]

Answer:

length of other leg = 20'

Step-by-step explanation:

Given:

One leg of triangle let it be base of triangle = 21'

Hypotenuse = 29'

To Find:

Third leg =perpendicular = ?

Solution:

Given is a right angled triangle with two of its sides given to us

We have Pythagoras theorem for right angled triangle and according to it

Pythagoras theorem is

for a right angled triangle

(hyp) ² = (perp)²+(base)²

We have the values of hyp and base

putting them in the equation we get

(29) ² = (perp) ²+(21) ²

841 = (perp) ² + 441

subtracting 441 from both sides we get

841 - 441 = (perp) ² + 441 - 441

400 = (perp)²

(perp) ²=400

Taking square root of both sides

$\sqrt{(perp)^{2} }=\sqrt{400}$

it gives us

perp = ± 20'

As it is length and it can not be negative so

perp = 20'

length of other leg = 20'

Mr. frankel bought 7 tickets to a puppet show and spent $24. he bought a combination of child tickets for $2 each and adult tick

nydimaria [60]

Let x be the number of child tickets he bought
Let y be the number of adult tickers he bought

① x+y=7 (child tickets+adult ticket=7 tickets in total)
② 2x+4y=24 (price of child tickets+price of adult tickets=$24 in total)

We may simply the second equation since all of the coefficients are divisible by 2.

① x+y=7
② x+2y=12

We can now use elimination by multiplying the second equation by -1.

② -(x+2y=12)
② -x-2y=-12

① x+y=7
② -x-2y=-12

Now putting the equations together,
-y=-5
y=5
x=2

Therefore he bought 2 child tickets and 5 adult tickets

A group of penguins swam 4/5 mile in 1/3 hour. Use the table to find how many miles the penguins swam in one hour if they swam a

Vinil7 [7]

Answer:

2.4 miles

Step-by-step explanation:

This is a simple ratio problem.

Penguins go 4/5 mile in 1/3rd hour. So how many miles will they go in 1 hour? Let that be x:

$\frac{\frac{4}{5}}{\frac{1}{3}}=\frac{x}{1}\\\frac{1}{3}x=\frac{4}{5}\\x=\frac{4}{5}*3=\frac{12}{5}$

That is 12/5 miles or 2 2/5 miles

In decimal, that's 2.4 miles
