Step-by-step explanation:
Answer:
The answer is below
Step-by-step explanation:
Let us assume that the age of Greg's brother (Gabe) is x years, and let Greg's age by y years. Since Greg is 10 years older than his brother gabe, then:
y = x + 10 (1)
Also. Greg is 3 times as old as Gabe, hence:
y = 3x (2)
From equation 1 and equation 2:
y = x + 10 = 3x
Hence:
3x = x + 10
Subtracting x from both sides gives:
3x - x = x + 10 - x
2x = 10
Dividing by 2:
2x/2 = 10/2
x = 5 years
y = x + 10 = 5 + 10 = 15 years
Therefore Gabe is 5 years old and Greg is 15 years old
Hello!
First you have to add the number of fish
52 + 61 + 87 = 200
Then you find the percentage of grass carps
61/200 = 0.305
Then you multiply what you just got with the estimated sample
800 * 0.305 = 244
The answer is 244
Hope this helps!
Answer:
40 square units
Step-by-step explanation:
The surface area is given by
LA = 2(wh+lh)
where h is the height l is the length and w is the width
We do not include the top or bottom
We know l=6 w=4 and h=2
LA = 2 ( 4*2 + 6*2)
lA = 2( 8+12)
= 2 (20)
= 40
The number sentence that applies the commutative property to the example is 4 × 3 = 12
<h3>Commutative property</h3>
Commutative property can be additive or multiplicative. It is a way of changing the position of a function or value in an expression without affecting the result
Examples are
A +B = B +A
AB = BA
Although the value were interchanged, the result were not affected. Hence the number sentence that applies the commutative property to the example is 4 × 3 = 12 since changing 3 and 4 does not affect the result
