Answer:The b is 15.7-2(a)
Step-by-step explanation:
2a+b=15.7
b=15.7-2a
The length will be a+a which is greater than length of b
The b is 15.7-2(a)
Answer:
The total number of Cats and Frogs
Step-by-step explanation:
Number of Birds Owned = B
Number of Cats = C
Number of Frogs =F
The expression that represents the total number of pets owned by Kelby
=B+(C+F)
NOTE: SUM/ADDITION = +
Therefore:
The expression C+F represents the total number of Cats and Frogs owned by Kelby.
It is $2.25 for 1 pound of apples and $9 for 4 pounds of apples
Find the radius, then double the radius measurement to find the diameter.
STEP 1:
find the radius
A= πr^2
plug in known numbers
68= (3.14)r^2
divide both sides by 3.14
21.6560509554= r^2
take the square root of both sides
4.6536062312 cm= r
STEP 2:
diameter equals two times the radius
D= 2 * 4.6536062312
D= 9.3072124625 cm (9.3 cm rounded to nearest tenth)
ANSWER: The diameter is 9.3072124625 cm (9.3 cm rounded to the nearest tenth)
Hope this helps! :)
