4(2.25w+3.1)-2.75w=44.9

9w+12.4-2.75w=44.9

9w-2.75w+12.4=44.9

44.9-12.4=32.5

9w-2.75w=32.5

6.3w/6.3=32.5/6.3

Answer:

w = 5.2

Step-by-step explanation:

4(2.25w + 3.1) - 2.75w = 44.9

9w + 12.4 - 2.75w = 44.9

6.25w + 12.4 = 44.9

6.25w = 32.5

w = 5.2

8/12*30

For number three, the answer is 38 Ibs on Mars.

4/10 = x/95

4*95/10= x

X= 380/10 which equals 38.

For 4, the answer is 48 oz of pineapple juice.

3 x 64/4 which equals to 48.

For 5, you will need 6 cups of flour.

What is the value of x?<br><br> A. 142<br> B. 152<br> C. 76<br> D. 71
Nadusha1986 [10]

Answer:

x has a value of 71, making D the correct answer.

Step-by-step explanation:

Because this is an isosceles triangle, we know that the bottom two angles are equal.  We also know that the sum of the angles inside a triangle will always come to 180°.  With that in mind, we can simply subtract 38° from 180° and divide by two to get the correct answer.

x = (180 - 38) / 2\\= 142 / 2\\= 71

So the correct answer is D, 71 degrees.

Chloe invests money in an account paying simple interest. She invests $200 and no money is added or removed from the investment.
MissTica

Answer:

2%

Step-by-step explanation:

Chloe's simple interest for 1 year is $4. You can get this by subtracting the amount she invested from the total amount she got after one year.

  • $204 - $200 = $4

Now that we know the simple interest, we can now get the simple interest rate or<em> simple percent interest per year </em>by dividing $4 by $200.

  • $4 ÷ $200 = 0.02

Let's change 0.02 into a percentage.

  • 0.02 x 100 = 2%

This means that every year, her investment will earn a <em>2% simple interest.</em>
