Luba_88 [7]3 years ago

Answer:

first one is -1, second one is also -1, third one is -1/2, the fourth one is 9/4, the fifth one is 2, and the last one (sixth) is 16/25.

Step-by-step explanation:

4x +3 = -1 all multiply by 13, = 4x + 3 = -1, subtract 3 on both sides, x= -1.  Do what I told you the first equation and you will get it. put all the denominators in common denominator which in this case is 6, then multiply everything by 6, add like terms, = -2x + 2 = 3, then subtract 2 on both sides, then divide -2 on both sides. put all denominators to 16 then multiply everything by 16, 4x -6 will = to 3, add 6 on both sides, 4x = 9, then divide 4 on both sides then you will get 9/4. put all of the denominators up to 12, and multiply everything by 12, then add like terms, 7 = 2x +3, subtract 3 on both sides, 4 = 2x, divide 2 on both sides now, and the answer is 2. the last one is also pretty simple, put all the denominators to 21, multiply everything by 21, add like terms, 16x = 25, divide 16 on both sides, then the answer is 16/25.

Split the surface area into geometric shapes as shown in the figure below.

Top part
The area of one triangle is
A₁ = (1/2)*(10 cm)*(4 cm) = 20 cm²
There are 3 of these triangles.

Vertical sides..
The area of one vertical side is
A₂ = (10 cm)*(6 cm) = 60 cm²
There 3 of them.

Bottom part
The triangle is equilateral with each side  = 10 cm, and each angle = 60 deg.
The area is (from the Law of Sines)  equal to
A₃ = (1/2)(10 cm)*(10 cm)*sin(60) = 43.3 cm²

The total surface area is
3A₁ + 3A₂ + A₃
= 3*20 + 3*60 + 4.3
= 283.3 cm²

Answer: The surface area is  283.3 cm²

The ratio of oranges to apples in Helen's basket is 4:3. The basket has 12 apples in it. How many oranges are in the basket?
frez [133]

Answer:

16 oranges

Step-by-step explanation:

The ratio of oranges to apples is 4:3 which means that for every four oranges, there are 3 apples.

Since there are 12 apples in the basket, to find the number of oranges, set up a ratio.

4/3 = x/12 (x represents the number of oranges)

Cross multiply.

48 = 3x

Divide by 3.

x = 16

There are 16 oranges in the basket.

Hope that helps.
