Does 38956 have 6 addend in its expanded form

kow [346]

Answer: 78

Step-by-step explanation:

First, we want to find the area of the outer triangles. Remember that the equation to finding the area of a triangle is (l x h) x 1/2. So, let’s substitute the values into the equation. It’ll be (6 x 7) x 1/2. Let’s solve! 6 x 7 = 42. Then, 42 x 1/2 = 21. But let’s not forget that we only found the area of one triangle. We still need to find the area of the other outer triangles. So, to do this, we take 21 and multiply by 3 since the other outer triangles have the same dimensions. We would get 63 as our total area for the outer triangles.

Next, we need to find the area for the inner triangle. We will use the same equation: (l x h) x 1/2. Let’s substitute! (6 x 5) x 1/2 will be our final equation. Now, let’s solve. 6 x 5 = 30. 30 x 1/2 = 15. So, as a process of elimination, our area for the inner triangle is 15.

Finally, we need to add the total areas we found together. Our total areas were 63 and 15. Let’s put this into an equation: 63 + 15 = ?. So, 63 + 15 = 78. So, after a long process, 15 is our answer!

Hope this helped!

Ket [755]

<h3><em><u>Question:</u></em></h3>

Lyla is shopping for school supplies. She has $20.00 to spend. She

plans to buy a package of pens for $4.98. She also wants to buy a

calculator. All calculators are being sold for 30 percent less than the

original price. write an inequality that can be used to find the original price, x, of a calculator lyla can buy.

<h3><em><u>Answer:</u></em></h3>

$4.98+0.7x\leq 20$ inequality that can be used to find the original price, x, of a calculator lyla can buy

<h3><em><u>Solution:</u></em></h3>

Given that,

Lyla has $ 20 to spend

So she can spend entire $ 20 or less than $ 20

Total amount she has = $ 20

She plans to buy a package of pens for $4.98

Cost of package of pens = $ 4.98

She also wants to buy a calculator

Let "x" be the original price of calculator

All calculators are being sold for 30 percent less than the original price

Selling price of calculator = original price - 30 % of original price

Selling price of calculator = x - 30 % of x = x - 0.3x = 0.7x

Selling price of calculator = 0.7x

<em><u>Thus a inequality can be framed as:</u></em>

Cost of package of pens + Selling price of calculator $\leq$ 20

$4.98+0.7x\leq 20$

This means that, combined cost of package of pen and selling price of calculator must be less than or equal to the amount with Lyla ( 20 $ )

Thus the inequality is found

5х + y = 16<br> х+ 6у = 38

Ainat [17]

Answer:

$(2,6)$

Step-by-step explanation:

Solve by substitution. Solve the second equation for x:

$x+6y=38\\\\x+6y-6y=38-6y\\\\x=38-6y$

Insert the value of x into the first equation:

$5(38-6y)+y=16$

Solve for y. Simplify multiplication using the distributive property:

$5(38)+5(-6y)+y=16\\\\190-30y+y=16\\\\190-29y=16$

Subtract 190 from both sides:

$190-190-29y=16-190\\\\-29y=-174$

Isolate the variable to find its value. Divide both sides by -29:

$\frac{-29y}{-29}=\frac{-174}{-29} \\\\y=6$

Now take the value of y and insert back into either equation to solve for x:

$5x+6=16$

Subtract 6 from both sides:

$5x+6-6=16-6\\\\5x=10$

Divide both sides by 5:

$\frac{5x}{5}=\frac{10}{5}\\\\ x=2$

Therefore, the solution to the system is $(2,6)$ .
