Answer:
The number of home runs that Lu hit is 4 and the number of home runs that Karrine hit is 6
Step-by-step explanation:
Let
x ----> represent the number of home runs Lu hit
y ---> represent the number of home runs Karrine hit
we know that
Together they hit 10 home runs
so
----> equation A
Karrine hit 4 more home runs than half the number of home runs Lu hit
so
---> equation B
substitute equation B in equation A
solve for x
Find the value of y
therefore
The number of home runs that Lu hit is 4 and the number of home runs that Karrine hit is 6
After simplifying The answer is -8/3
Answer:
x = 30
Step-by-step explanation:
The perimeter is the sum of all of the sides of a shape. Therefore, because the sum is equivalent to 104 inches and we are given the lengths of all three sides, we can add the three sides together and set them equal to 104 in order to solve for x.
(x + 3) + (x + 4) + (x + 7) = 104 Drop the parentheses.
x + 3 + x + 4 + x + 7 = 104 Combine like terms (variables first!).
3x + 3 + 4 + 7 = 104 Now, combine constant terms.
3x + 14 = 104 Subtract 14 from both sides.
3x = 90 Divide by 3 on both sides of the equation.
x = 30
Step-by-step explanation:
normal weight = 100%
gained = 10%
-------------- +
total 110% (which is equal to 88 kg)
so, normal weight= 100/110 × 88 = 80 kg
Answer:
Area = 6647.610055 cm^2
Circumference = 289.02652413 cm
Step-by-step explanation:
Area of Circle: Area = π*r^2
Circumference: C = 2*π*r or π*d
Area = π * 46^2 = 6647.610055
Circumference = 2*π*46 = 289.02652413
