Solve for x:5x/2=330/4

1 answer:

5 0

First we have to get x by itself, so we multiply two on each side,

then we get 5x=660/4, I like to simplify here, so I would change it to 5x=165, then we divide each side by 5

x=33

if a rental car agency charges $17 per day plus 10 cents per mile to rent a certain car.Another agency charges $21 per day plus

SashulF [63]

17+(10X)= 21+(5x) is the equation
17 +(10x1)= 21+(5x1)
17+10=21+5
27=27
So your answer is it takes 1 mile per day
Hope its right lol

What is the the area of the triangle in the composite figure above?

Flauer [41]

Answer:

$10 in^{2}$

Step-by-step explanation:

Subtract 13 from 17 to get the length of the base. Then add the 1, 1, and 3 together to get the height. Then you use the area formula for a triangle.

The angles in a triangle are in the ratio 1:2:3. Show that this triangle is a right-angled triangle. The hypotenuse of the trian

natita [175]

Answer:

see explanation

Step-by-step explanation:

(a)

Sum the parts of the ratio , 1 + 2 + 3 = 6 parts

Divide sum of angles in a triangle by 6 to find the value of one part of the ratio.

180° ÷ 6 = 30° ← value of 1 part of the ratio

2 parts = 2 × 30° = 60°

3 parts = 3 × 30° = 90°

Since there is an angle of 90° then the triangle is right.

(b)

The shortest side is the side opposite the smallest angle of 30°

Using the sine ratio and the exact value

sin30° = $\frac{1}{2}$ , then

sin30° = $\frac{opp}{hyp}$ = $\frac{opp}{19}$ = $\frac{1}{2}$ ( cross- multiply )

2 opp = 19 ( divide both sides by 2 )

opp = 9,5

Shortest side in the triangle is 9.5 cm

John needs 150 feet of rope to section off part of his barn. At a local hardware store he can buy a 30 yard spool for $24 or he

Sphinxa [80]

Answer:

30 yards for 24 vs 1 foot for 25 cents

so lets multiple the yards by 3 to see how many feet

90 feet = 30 yards

90 feet 24 dollars

now lets divide 90 by 24

3.75 so 3.75 per foot

so the second one is way better

Hope This Helps!!!
