-3w-4=3+3
w=?????????
Answer:
-3.33333
Step-by-step explanation:
-3w - 4 = 3 + 3
Combine like terms
-3w - 4 = 6
Add 4 on both sides
-3w - 4 + 4 = 6 + 4
-3w = 10
Divide by -1 to isolate the variable
-3w/-3 = 10/-3
w = - 3.33333 ( the 3 keeps repeating)

Suppose y varies directly with x, and y = 13 when x = 4. What direct variation equation relates x and y? What is the value of y when x = –6?
Answer:
direct variation equation: y = 13/4x
y = -19.5 when x = -6
Step-by-step explanation:
y = kx where 'k' is the constant to proportionality
13 = 4k
k = 13/4
equation: y = 13/4x
plug in -6 for 'x' to find value of 'y'
y = 13/4(-6)
y = -19 1/2

A flagpole casts a shadow of 25.5 meters long. Tim stands at a distance of 15.4 meters from the base of the flagpole, such that the end of Tim's shadow meets the end of the flagpole's shadow. If Tim is 2.3 meters tall, determine and state the height of the flagpole to the nearest tenth of a meter.
Answer:
5.8 meters
Step-by-step explanation:
The formula to calculate this is given as:
Height/ Shadow
Shadow of the pole = 25.5 m
Height of the pole = x m
Tim's shadow = Height of the pole - Tim's distance
25.5 m - 15.4 m = 10.1 m
Tim's height = 2.3 m
Hence:
x/25.5 = 2.3/10.1
Cross Multiply
10.1x = 25.5 × 2.3
x = 25.5 × 2.3/10.1
x = 5.8069306931 m
Approximately = 5.8m
Hence, the height of the flagpole = 5.8m

Kamilah noticed that three different-sized boxes of the same cookies were on sale at a grocery store. The 0.425 kg box was on sale for $3.59, the 0.74 kg box was on sale for $4.88, and the 0.95 kg box was on sale for $7.29. Which box of cookies was the best buy? Explain your reasoning. To get you started: 3.59 : 0.425 1kg/ 0.425kg= 2.35 0.425 x 2.35= 1kg $3.59 x 2.35= $8.44 3.59 : 0.425 -> $8.44 : 1kg
Answer:
The best buy is the 0.74 kg box
Step-by-step explanation:
Kamilah noticed that three different-sized boxes of the same cookies were on sale at a grocery store.
We find the unit price for 1 box
a) The 0.425 kg box was on sale for $3.59
= 1 kg = $3.25/0.425
= $7.6470588235
b) the 0.74 kg box was on sale for $4.88,
1 kg = $4.88/0.7$
= $6.5945945946
c) the 0.95 kg box was on sale for $7.29.
1 kg = $7.29/0.95
= $7.6736842105
Which box of cookies was the best buy?
The best buy is the 0.74kg box because 1kg of this box has a lesser price compared to the others.

A student has a container with a volume of 0.5 liter. He estimates the volume to be 0.4 liter. By what percent is the student's estimate off?
Answer:
20
Step-by-step explanation:
0.5-0.4=0.1,0.1/0.5×100= 20
The students's estimation is 80%.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given that a student has a container with a volume of 0.5 liter.
He estimates the volume to be 0.4 liter.
Now to find the percentage of estimation,
estimated volume = correct volume × required percentage / 100
0.4 = 0.5 × required percentage / 100
Required percentage = 0.4 × 100 / 0.5
Required percentage = 0.4 × 100 / 0.5
Required percentage = 80%
Therefore, the students's estimation is 80%.
