Answer:
12
Step-by-step explanation:
think of the ratio as a fraction. 20/3 if f is 20 and t is 3 then when f is 80 t should be 12 because 20*4 is 80 and 3*4 is 12
=========================================================
Work Shown:
(# of fish)/(# of turtles) = (# of fish)/(# of turtles)
20/3 = 80/x
20x = 3*80 ........ cross multiply
20x = 240
x = 240/20 ....... divide both sides by 20
x = 12
There are 12 turtles in the pond.
Note how the ratio 80:12 reduces fully to 20:3 after dividing both parts by 4.

look at the shaded shapes the area of shape a is 3cm what is the area of shape b
Answer:
(3×7)+(1.5×5)
21+7.5
28.5cm^2
Answer:
= 28.5cm²
Step-by-step explanation:
A is a full diamond which is equal to 3cm²
B has: 7 full diamonds and five 1/2 diamonds
Five 1/2 diamonds = 2 full diamonds and 1/2 a diamond.
If 1 diamond(A) = 3cm²
What about 9 diamonds = ?
= (9 × 3) ÷1
= 27cm²
If 1 diamond(A) = 3cm²
What about 1/2 a diamond = ?
= 1/2 × 3
= 1.5cm²
Total = 27 + 1.5
= 28.5cm²

3x+15 = 4x - 5
-3x -3x
15=x-5
+5 +5
x=20
4(20)-5 = 75
Answer:
75
Step-by-step explanation:
1 and 2 are corresponding angles meaning that they are equal to each other or congruent
so we set up an equation
4x-5=3x+15 and since for x
step 1 subtract each side by 3x
4x-3x=x
now we have
x-5=15
step 2 add 5 to each side
5+15=20
x=20
now we just plug in 20 to 4x - 5
4x20=80
80-5=75
therefore your answer is 75

Rewriting the whole as an Equivalent Fraction
2.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 2 as the denominator :
5t 5t • 2
5t = —— = ——————
1 2
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
5t • 2 - (7) 10t - 7
———————————— = ———————

Equation at the end of step

:
When a fraction equals zero :
3.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
10t-7
————— • 2 = 0 • 2
2
Now, on the left hand side, the 2 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
10t-7 = 0
Solving a Single Variable Equation:
3.2 Solve : 10t-7 = 0
Add 7 to both sides of the equation :
10t = 7
Divide both sides of the equation by 10:
t = 7/10 = 0.700
One solution was found :
t = 7/10 = 0.700
