Answer: There were 78 red apples at the party.
Step-by-step explanation:
This situation can be represented by the equation
x + 3x + 2(3x) = 130 where x is the number of green apples, 3x is the number of yellow apples and 2(3x) is the number of red apples.
Now solve for x
x +3x +2(3x) =130
4x + 6x = 130
10x = 130
x = 13
Now we know that x is 13 so put it into the expression for red apples and solve for the actual number of red apples.
2 * (3*13) = ?
2 * 39 = 78
Do 1.2 then the division box and inside the box put 251.2 and the answer is <span>209.333333333 with an infinite 3</span>
Answer:
12.5cm
Step-by-step explanation:
the figure appears to be a circle centered around point B, wherein segment CB is a radiai and segment DF is a diameter.
radiai(radius plural) are known to be 1/2 the length of diameters
(1/2) × 25 = 12.5
Answer:
The correct answer is option D. -126
Step-by-step explanation:
<u>Points to remember</u>
<u>Composite functions</u>
f(x) and g(x) be the functions then,
(f - g)(x) = f(x) - g(x)
<u>To find the value of (m - n)(-5)</u>
Let m(x) = x³ and n(x) = √ (6 + x)
(m - n)(x) = m(x) - n(x)
= x³ - √( 6 + x)
(m - n)(-5) = m(-5) - n(-5)
= x³ - √( 6 + x)
= (-5)³ - √( 6 + -5)
= -125 - √1
= -125 -1
= -126
The correct answer is option D. -126
Answer: 2
Step-by-step explanation:
Multiply by 2 each side and the result will give the numbers of the larger triangle.
