One friend solves
7(x + 4) = 49 by dividing each side
by 7 and then subtracting 4 from
each side. Another friend solves it by
first distributing the 7 on the left side
of the equation, then subtracting 28
from each side, and finally dividing
each side by 7. Which friend uses the
correct method? Explain.
Answer:
the second friend
Step-by-step explanation:
Answer:
both methods are correct
Step-by-step explanation:
Given
7(x + 4) = 49 ( divide both sides by 7 )
x + 4 = 7 ( subtract 4 from both sides )
x = 3
---------------------------------------------------------
Given
7(x + 4) = 49 ← distribute parenthesis by 7
7x + 28 = 49 ( subtract 28 from both sides )
7x = 21 ( divide both sides by 7 )
x = 3
As shown both methods are equally valid
Jack works at a local warehouse unloading boxes of material from trucks and then stacking them for distribution from the warehouse. Each box he unloads weighs 65 pounds. Each stack of boxes cannot exceed a total of 800 pounds. How many boxes can be in a stack?
Answer:
12 boxes
Step-by-step explanation:
800/65=12.307, since this is not a whole number, and the limit cannot exceed 800 pounds in a stack, you must round down to 12

which is a solution to the systen of equations. x+3y=18. x+2y=14 A) 6,4 B) 4,6 C) 6,-4 D) -4,6
Step-by-step explanation:
• Elimination (find y) :
x + 3y = 18
x + 2y = 14 _
y = 4
• Substitute y = 4 to one equation :
x + 3y = 18
x + 3(4) = 18
x + 12 = 18
x = 18 - 12
x = 6
• The set of equations :
{x, y} = {6, 4}
So, the solution to that system equation is 6, 4 (A)

Answer:
Step-by-step explanation:
For the first statement, we need to find the percentages of sold hats. The percentage of white hats sold was (120/200) * 100 = 60% and the percentage of black hats sold was (210/300) * 100 = 70%. The first statement is "The musical group sold 60% of the white hats and 70% of the black hats."
The second statement asks us to compare the 2 percentages, and since 70% > 60%, the statement would be "A greater percentage of black hats were sold." Hope this helps!

Answer:
x=12
Step-by-step explanation:
9x+5=113 then subtract 5 from both sides
then you get 9x=108 then divide both sides by 9 to get x=12
Answer:
x = 12
Step-by-step explanation:
9x + 5 = 113
Subtract 5 from each side
9x + 5-5 = 113-5
9x = 108
Divide each side by 9
9x/9 = 108/9
x = 12

In a football drill, Ron is standing 30 yards directly east of John, and Bill is standing 40 yards directly north of John. If the football is thrown from Ron to Bill and then from Bill to John, how many yards did the football travel?
Answer:
D, 90
Step-by-step explanation:
See image below.
To find the distance from Bill to Ron, we will use the Pythagorean Theorem, which is a^2+b^2=c^2.
(a and b being the legs of the triangle, they form the 90 degree angle. c=hypotenuse, or the side that is opposite from the 90 degree angle)
In this example, a=30 and b=40.
30^2+40^2=c^2
900+1600=c^2
2500=c^2
c=50.
Then, to find the yards thrown, we will add the distance from Ron to Bill and the distance from Bill to John. This can be written as 50+40, which equals 90 yards.

Step-by-step explanation:
Fig rolls:
If you buy 4 you get 2 half price.
So, 1.34/2=0.67
So, (1.34*2)+(0.67*2)=£4.02
Crisps:
If you buy 9 crisps you get 9 for the price of 6.
So, 1.59*6=£9.54
Total:
£4.02+£9.54=£13.56
