<span>-5(4x-2)=-2(3+6x)
First use the distributive property on</span>-5(4x-2) and -2(3+6x)
<span>-5(4x-2)=-2(3+6x)
-20x + 10 = -6 - 12x
Now combine like terms
</span>-20x + 10 = -6 - 12x
-20x + 12x = -6 - 10
Now finish simplifying
-20x + 12x = -6 - 10
-8x = -16
-8x / -8 = -16 / -8
x = 2
Answer:
B. 36 square meters
Step-by-step explanation:
Find the areas of the rectangle and triangle. Then, subtract the area of the triangle from the area of the rectangle to get the area of only the figure.
rectangle A = 8(6) = 48 square meters
triangle A = 1/2(8)(3) = 12 square meters
48 - 12 = 36 square meters
Answer:
3/16
Step-by-step explanation:
By drinking 3/8 liters of 1/2 liter juice it means the question tests the ability to multiply fractions. Since she drank 3/8*1/2=3/16
We multiply the numerators and denominators separately ie 3*1/(8*2)=3/16
Therefore, Alisa consumed 3/16 or 0.1875 or 18.75% of the juice.
Since the question was in fractional form, it is prudent to also express answer in fractions hence the right answer is 3/16
Answer:
x=7
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
The mean = 17.54
Step-by-step explanation:
Form a table as below;
<u>Interval Frequency{f} Midpoint of frequency{x} fx </u>
1-7 19 4 76
8-10 14 9 126
11-15 15 13 195
16-20 20 18 360
21-35 10 28 280
36-50 13 43 559
Sum 91 1596
The mean of grouped data = Sum of { Interval Midpoint * Frequency } /Sum of frequency
The mean= 1596 / 91
The mean = 17.54
