Which number belongs to the solution set of the equation below?

ollegr [7]

The correct answer would be: C. 44
Explanation: If you're trying to find out x's value, you have to do the inverse operation which means if it's subtraction, you add. So to find x's value, you'd add 36 + 8 = x. And 36 + 8 = 44. So therefore, x = 44. That means the answer is C.

A number increased by 5 is two times the number

marin [14]

Let x be the number. x + 5 = 2x. 5 = x because you isolate for x by moving it to the right side, meaning you’d have to subtracts 1 x from 2x

How do you find the unit rate

Sergio039 [100]

Answer:

Step-by-step explanation:

To get the unit to equal 1, divide both numbers by the denominator; your answer is the number you get by dividing the numerator by the denominator. Use this method to calculate unit cost, too—you're calculating how much 1 item is worth, after you're given the amount that multiple items cost.

Given that L is the centroid of triangle FGH, find LG.

olga55 [171]

Well the centroid is the point that connects the median of a side with the opposite vertex. This means that each line is split i half. Notice that line HG is split in half by point K. that means that each of the segments that K splits is equal. so we know
HK = KG

and we know
HK = 3x
KG = x + 8

since
HK = KG then
3x = x + 8
2x = 8
x = 4

now we have x. we know that the each line that runs from a midpoint to a vertex is seperated by the centroid. the 2 line segments are a 2:1 ratio. so
2*JL = 1LG

we know
JL = x + 3

so
2 * (4 + 3) = LG
LG = 14

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 5 large boxes and 3 small boxes has a t

faltersainse [42]

Answer:

one large box equals 15.75kg

one small box equals 13.75kg

Step-by-step explanation:

First, identify your variables:

Let "l" represent the weight of one large box.

Let"s" represent the weight of one small box.

Then, stack the two equations on top of each other:

$5l+3s=120\\7l+9s=234$

Next, multiply the first equation by 3 so we can use elimination of the "s" variable to find the "l" variable first:

$3(5l+3s=120)\\7l+9s=234\\\\15l+9s=360\\7l+9s=234$

Now, subtract the two equations to cancel out the s-variable and find the l-variable:

$15l+9s=360\\-(7l+9s=234)\\8l=126\\\frac{8l}{8}=\frac{126}{8}\\l=15.75$

Then, substitute your l-variable in the original first equation to find the s-variable:

$5l+3s=120\\5(15.75)+3s=120\\78.75+3s=120\\78.85-78.75+3s=120-78.75\\3s=41.25\\\frac{3s}{3}=\frac{41.25}{3}\\s=13.75$

With all the information that is collected, you find that one large box weighs 15.75kg and one small box weighs 13.75kg.
