Jamal has $40 to buy tickets to a performance for himself and his friends. Ifx
he buys a $10 membership, he can buy tickets for $5 each. How many tickets can he
buy while remaining within his budget?
He can buy 6 tickets remaining within his budget .
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the question
Jamal has $40 to buy tickets to a performance for himself and his friends .
If he buys a $10 membership
Money left = $40 - $10
= $30
he can buy tickets for $5 each
Now,
tickets he can buy while remaining within his budget
By using unitary method
= $30 / $5
= 6 tickets
Hence, He can buy 6 tickets remaining within his budget .

A tank that is 40% full contains 650 gallons of water. On a side sheet of paper, use a double number line to find the maximum capacity of the water tank.
What did you get?
gallons
Answer: max capacity is 1625 gallons.
Diagram is shown below.
=========================================================
Explanation:
We'll draw two horizontal number lines to help make a comparison or connection between percentages and tank capacity.
For the top number line, make 5 sections with the labels: 0%, 20%, 40%, 60%, 100%. The reason I'm picking 5 is because 40% = 40/100 = 2/5. So having 40% capacity means we're 2/5 full. That denominator 5 tells us how to subdivide each number line.
The bottom number line will also have 5 sections. We only know one label for this bottom portion right now. That label is 650. Place this directly under the "40%". This visually is one way to represent that 650 gallons is 40% filled. See the diagram below.
Cut the 650 in half to get 325. This corresponds to 40% cut in half to get 20%. Therefore, 325 will go under the 20%. Being 20% full means we have 325 gallons of water.
To figure out the 60% portion, we will multiply 325 by 3. This is because 3*20% = 60%, so 3*325 = 975. We'll write "975 gallons" under the "60%"
Then we have 1300 gallons under the 80% since 4*325 = 1300. Note how 4*20% = 80%, so that's where the '4' multiplier comes from.
Finally, we multiply 325 by 5 to get 1625 and that represents the full tank's capacity. Technically we could have just jumped to this directly without having to find the 60% or 80% capacity values, but it's good practice I think.
Again the diagram is shown below. The answer we're after is at the very bottom right corner. It's under the 100% to indicate the tank is completely full, or has reached max capacity.
-----------------------
Here's a way to find the answer without a double number line. This method involves setting up a proportion.
(40% full)/(650 gallons) = (100% full)/(x gallons)
40/650 = 100/x
40x = 650*100
40x = 65000
x = 65000/40
x = 1625
We confirm that the tank's max capacity is 1625 gallons.

Compare the slope equation y=3/5x+2 with the slope shown in the ordered pairs below. which has a greater rate of change?
(1, 2.6), (3, 3.8), (5, 5), (7, 6.2)
(the 3/5 is a fraction)
Answer:
They have the same rate.
Step-by-step explanation:
If we use rise over run formula
(3.8 - 2.6) / (3 - 1) = .6
3/5 = .6
They both have a slope of 0.6

Complete question :
Jelena has a piece of fabric in the shape of a parallelogram the height is 10 feet and its base is 16 feet because the fabric into four equal parallelograms by current base and the height in half what is the area of each new parallelogram?
Answer:
40 ft²
Step-by-step explanation:
Given that:
Height = 10 feets
Base = 16 feets
Area of parallelogram = height * base
Area of parallelogram = 10 * 16 = 160 ft²
Area of each new parallelogram :
Area of parallelogram / number of divisions
= 160ft² / 4
= 40 ft²

Jackie drives 160 miles from Gary, Indiana to Indianapolis, Indiana in 2 1/2 hours. At that rate, how long would it take her to drive from Gary to Detroit, Michigan, which is a distance of 240 miles?
Answer:
3.75 hours
Step-by-step explanation:
Given data
DIstance driven from Gary, Indiana to Indianapolis= 160 mile
Time taken= 2 1/2 hours or 2.5 hours
Speed= distance/time
Speed= 160/2.5
Speed= 64 miles per hours
We want to find the time it will take to drive 240 miles at the same speed
Time= distance/speed
Time= 240/64
Time= 3.75 hours

Answer:
x = 11
Step-by-step explanation:
33 divided by 3 is 11, and 11 times 3 is 33.
answer:
11
step-by-step explanation:
the easiest way to explain this is just to divide
33/3
which gets you the answer of 11
but here is another way to explain this
3x = 33
since the 3 and the x are times/multiplying each other and we need to get x by its self, all we do is move the 3 to the other side ( where 33 is ) but instead of multiplying them, we have the change the sign to dividing
3x = 33
/3 ----|>
( dont forgot to rewrite the equation!! )
x = 33/3
now all we need to do is divide 33 by 3 which gives us the answer of
11

5. x/6 = 4
6. y/7 = -1
7. - x/11 = 10
8. x/4 = 5/6
Answer:
Look down.
Step-by-step explanation:
1. x= 10
2. x= 7
3. d= -15/7
4. y= 6/23
5. x= 24
6. y= -7
7. x= -110
8. x= 20/6 or 10/3
Answer:
x = 10x = 7d = -15/7 y = 6/23x = 24 y = -7 x = -110 x = 10/3Step-by-step explanation:
1) 2x = 20, value of x?
→ 2x = 20
→ x = 20/2
→ [ x = 10 ]
2) 6x = 42, value of x?
→ 6x = 42
→ x = 42/6
→ [ x = 7 ]
3) -7d = 15, value of d?
→ -7d = 15
→ d = 15/-(7)
→ [ d = -15/7 ]
4) 23y = 6, value of y?
→ 23y = 6
→ [ y = 6/23 ]
5) x/6 = 4, value of x?
→ x/6 = 4
→ x = 4 × 6
→ [ x = 24 ]
6) y/7 = -1, value of y?
→ y/7 = -1
→ y = -1 × 7
→ [ y = -7 ]
7) -x/11 = 10, value of x?
→ -x/11 = 10
→ -x = 10 × 11
→ -x = 110
→ [ x = -110 ]
8) x/4 = 5/6, value of x?
→ x/4 = 5/6
→ x = (5/6) × 4
→ x = 20/6
→ [ x = 10/3 ]
These are required values.
