Determine the value of x in the diagram below
Answers
Answer:
x =32
Step-by-step explanation:
create equation
180 = 3x + 20 + 2x
combine like terms
180= 3x + 20 + 2x
180=5x + 20
subtract 20 from both sides of the equation
180=5x + 20
180-20= 5x +20 -20
simplify
160= 5x
divided both sides by 5
160/5=5x/5
solution
32= x
A recipe calls for 1/2 cup of ingredient A for every 1 2/5 cups of ingredient B. You use 2 cups of ingredient A. How many cups of ingredient B do you need?
Answers
Answer:
5 3/5 cups of Ingredient B
Step-by-step explanation:
A recipe calls for 1/2 cup of ingredient A for every 1 2/5 cups of ingredient B. You use 2 cups of ingredient A. How many cups of ingredient B do you need?
This is calculated as:
1/2 cups of Ingredient A = 1 2/5 cups of Ingredient B
This means:
1/2 cups of Ingredient A = 7/5 cups of Ingredient B
2 cups of Ingredient A = x
Cross Multiply
2 × 7/5 = 1/2 × x
x = 2 × 7/5/1/2
x = 2 × 7/5 ÷ 1/2
x = 2 × 7/5 × 2/1
x = 28/5
x = 5 3/5 cups of Ingredient B
Hence, For 2 cups of Ingredient A, 5 3/5 cups of Ingredient B is needed

A decagon has 10 sides so its interior angles add up to 180(10) - 360 = 1440 degrees. Therefore, on average, each interior angle is 144 degrees and each exterior angle is 36 degrees. The sum of the exterior angles is 10 x 36 = 360 degrees.
Step-by-step explanation:
The total sum of the interior angles of a simple decagon is 1440°
the ratio of 5 more than a number to 20 less than that number is 8:3. What is the number?
Answers
Answer:
35
Step-by-step explanation:
Let the number = y ;
5 more than the number = y + 5
20 less than that number = y - 20
Ratio = 8:3;
Solution:
Ratio of the number:
[tex]\frac{y + 5}{ y -20}[/tex] = [tex]\frac{8}{3}[/tex]
Now cross multiply and solve for y;
3(y+5) = 8(y-20)
3y + 15 = 8y - 160
3y - 8y = -160 - 15
-5y = -175
y = 35

Mr. Martinez's limo drove 15 miles south to Candy Land for some delicious gumdrops, then 5 miles east to Chuck E. Cheese for some scrumptious pizza. How far is Mr. Martinez from his starting point? Round your answer to the nearest tenth if necessary.
Answers
Answer:
15.8 miles
Step-by-step explanation:
Given that:
Distance driven south = 15 miles
Distance driven east = 5 miles
How far is Mr. Martinez from his starting point?
Using Pythagoras :
Distance from starting point(d) :
d = √(15)² + (5)²
d = √225 + 25
d = √250
d = 15.811388
d = 15.8 miles
