Mathematics
1 answer:
Viefleur [7K]3 years ago
8 0

Answer:

Step-by-step explanation:

1. x + 5.3 = 10.1

combine the like terms

x = 10.1 - 5.3

x = 4.8

2. x - 4.2 = 12.9

combine the like terms

x = 12.9 + 4.2

x = 17.1

3. 1.5x = 60

divide both sides by 1.5

x = 60/1.5

x = 40

4. x/1.3 = 1.8

cross multiply

1.3 goes to 1.8 and x stands alone

x = 2.34

Hope this helps

The length of the base of an isosceles triangle is x. The length of a leg is 4x-6. The perimeter of the triangle is 60. Find x.
lbvjy [14]

Answer:

Perimeter of a triangle = add all sides

Both the legs of the isosceles triangle are always EQUAL.

x+4x-6+4x-6 = 60

9x-12 = 60

9x = 60+12

9x = 72

x = 8

Seattle, wa and san francisco, ca lie on the same longitudinal line. san francisco is at 38° latitude and seattle is at 47° lati
Varvara68 [4.7K]

Step 1.

Calculate measure of angle α:

47^o-38^o=9^o

Step 2.

Calculate what fraction of the angle 360° ​​is the angle α:

\dfrac{9^o}{360^o}=\dfrac{1}{40}

Step 3.

Calculate the circumference of the Earth (circle):

C=2\pi r\to C=2\pi\cdot4000=8000\pi\ mi

Step 4.

The length of arc is equal 1/40 of the circumference:

\dfrac{1}{40}C=\dfrac{1}{40}\cdot8000\pi=200\pi\ mi

\pi\approx3.14\to\dfrac{1}{40}C\approx200\cdot3.14=628\ mi


<h3>Answer: A) 628 miles</h3>

What theorem or postulate can be used to justify that the two triangles are congruent? Write a congruence statement.
Alinara [238K]

B

ASA is short for angle side angle, which you can see from angle B and angle D being congruent (all right angles are congruent), the congruent marks on line BE and line ED, and the vertical angles AEB and DEC.

D is not the answer because B and D are not in the same 'place' when naming. Silly as it is, it counts.

Hope this helps!
