Answer:

Step-by-step explanation:

1) The sum of the angles in a triangle is 180 degrees. Therefore,

50 + 2x + 3x - 10 = 180

50 - 10 + 2x + 3x = 180

5x + 40 = 180

5x = 180 - 40 = 140

x = 140/5 = 28

2) 3x + 15 + 4x + 5 + x = 180

8x + 20 = 180

8x = 180 - 20 = 160

x = 160/8 = 20

3) 3x + 5x + x = 180

9x = 180

x = 180/9 = 20

4) The triangle is an isosceles triangle. The base angles are equal. Therefore,

x + x + 48 = 180

2x = 180 - 48 = 132

x = 132/2 = 66

5) 110 + 6x + 8x = 180

14x = 180 - 110 = 70

x = 70/14 = 5

The measure of angle C is

8 × 5 = 40

Answer:

1) 2x + 3x - 10 + 50 = 180

5x = 180 - 50 + 10 = 140

x = 140/5 = 28°

2) 3x + 15 + 4x + 5 + x = 180

8x = 180 - 15 - 5 = 160

x = 160/8 = 20°

Angle A = 3 (20) + 15 = 60 + 15 = 75°

3) x + 3x + 5x = 180

9x = 180

x = 20°

4) 48 + 2x = 180

2x = 180 - 48 = 132

x = 132/2 = 66°

5) 110 + 6x + 8x = 180

14x = 180 - 110 = 70

x = 70/14 = 5°

Angle C = 8 * 5 = 40°

Geraldo has 3 fewer marbles than Yan. Together, they have 21 marbles. Which equation

EleoNora [17]

Answer:

geraldo has 9 marbles and yan has 12

Step-by-step explanation:

x + (x-3) = 21

x + x - 3 = 21

2 x - 3 = 21

Explanation:

In this problem, let us first analyze the situation. It says here that Geraldo and Yan both had marbles of their own. The problem states that together, they have a total of 21 marbles. However, we know here from the problem that they have different number of marbles each. Geraldo seems to have lesser number of marbles than Yan. Yan have three marbles more than Geraldo.

We can write the equation starting from assigning the unknown.

We'll use x.

x is the number of marbles that Yan have.

if x is Yan's, then, we can say that x-3 is Geraldo's.

Put them together into the equation.

Yan's plus Geraldo's is equal to 21.

Substitute using the represented unknowns.

x + (x-3) = 21.

In solving, we can also rule out that:

x + x - 3 = 21

2 x - 3 = 21

2 x = 21 + 3

2 x = 24

x = 12

x - 3 = 9

Yan has 12 marbles

and Geraldo has 9 marbles.

Complete the steps to demonstrate why you multiply by the reciprocal when dividing fractions. Find 1/4 ÷ 3/8. ..................

Nataliya [291]

To complete the steps to demonstrate why you multiply by the reciprocal when dividing fractions.

To find
$\frac{1}{4}\div\frac{3}8}$

Step 1:
Rewrite it as
$\frac{\frac{1}{4}}{\frac{3}{8}}$ .

Step 2:
Multiply the numerator and the denominator by the reciprocal of
$\frac{3}{8}$ .

 $\frac{\frac{1}{4}}{\frac{3}{8}}=\frac{\frac{1}{4}}{\frac{3}{8}}\times\frac{\frac{8}{3}}{\frac{8}{3}}$

Step 3:
Simplify the denominator
$\frac{\frac{1}{4}\times\frac{8}{3}}{1}$

Step 4:
Simplify the fraction
 $\frac{1}{4}\times\frac{8}{3}$ .

We complete the solution as follows:
 $\frac{1}{4}\times\frac{8}{3}=\frac{1\times8}{4\times3}\\ \\=\frac{8}{12}=\frac{4\times2}{4\times3}=\frac{2}{3}$
