Answer:
Miguel has video games = 14
Beth has video games = 10
Step-by-step explanation:
Miguel has video games = m
Beth has video games = b
We make the equations:
m=b+4 (Miguel has 4 more video games than Beth)
m+b=24 (together they have a total of 24 video games)
So, the system of equations is:
[tex]m=b+4\\m+b=24[/tex]
Now, solving these system of equations to find values of m and b
Let:
[tex]m=b+4--eq(1)\\m+b=24--eq(2)[/tex]
Put value of m from equation 1 into equation 2
[tex]m+b=24\\b+4+b=24\\2b=24-4\\2b=20\\b=\frac{20}{2}\\b=10[/tex]
We get value of b: b=10
Now, finding value of m by putting value of b in equation 1
[tex]m=b+4\\m=10+4\\m=14[/tex]
So, We get value of m: m= 14
Therefore:
Miguel has video games = m = 14
Beth has video games = b = 10
Answer:
m+b=24
m=b+4

Suppose that Cecil, the tightrope walker, can only travel lengths of 5 feet, 6 feet, and 8 feet.
• He can travel forward (positive 5, 6, 8)
• backward negative (-5, -6-8)
can go past the ladder and come back.
.
Show TWO number expressions that will represent a way for Cecil to cross a tightrope of

Answer:
The two expressions are;
1) -8 ft. + 3 × 6 ft. = 12 feet
2) -6 ft. + 2 × 5 ft. + 8 ft. = 12 feet
Step-by-step explanation:
The given parameters are;
The lengths in feet Cecil can travel = 5 feet, 6 feet, and 8 feet
The distances Cecil can travel forward = (positive 5, 6, 8)
Backwards Cecil can travel distances of (-5, -6, -8)
Cecil can go forward past the ladder and return back
Therefore, the number expressions by which Cecil can cross a tightrope 12 feet long are;
1) -8 ft. + 3 × 6 ft. = 12 feet
Which is to go back 8 feet and then to go forward 6 feet three times
2) -6 ft. + 2 × 5 ft. + 8 ft. = 12 feet
Which is to go back 6 feet then to go forward in 5 feet two times and then in forward again in 8 feet.

C to the power of 5 x c
Answer:
c to the power of 5 x c = c⁶
Step-by-step explanation:
We need to find the expression for c to the power of 5 x c.
c to power 5 is : c⁵
Now, multiply c⁵ and c.
c⁵ × c = c⁵⁺¹
= c⁶
So, the final expression is c⁶. Hence, this is the required solution.
Answer:
Step-by-step explanation:
c to the power of 6
p(x-3)= -x³+cx²-4x+3
Answer:
p= −x^3−x^2c+4x−3/x−3
c= p/x− 3p/x^2 +x +4/x−3/x^2
Step-by-step explanation:
I hope this helps!!! I have no idea what you were trying to find so I put the value of p and c so I hope this helps you :)
Answer:
c=4
Step-by-step explanation:
Find the value of c so that the polynomial p(x) is divisible by (x−3)
p(x)=−x^3+cx^2 −4x+3
if p is p(3)=-(3)^3 +c(3)^2 -4(3) +3
simplify p(3)= -27+9c -12 +3
combine p(3)=-36+9c
get c alone -9c=-36

If a rectangular prism was 5 feet long, 5 feet high and 6 feet deep, how much would it weigh if one cubic foot weighed 0.1 tons?
Answer:
Total weight = 1,500 tons
Step-by-step explanation:
Given:
l = 5 ft
b = 5 ft
h = 6 ft
One cubic foot weighed = 0.1 tons
Find:
Total weight
Computation:
Volume = lbh
Volume = (5)(5)(6)
Volume = 150 ft³
Total weight = Volume / 0.1
Total weight = 150 / 0.1
Total weight = 1,500 tons

1.5 is another way to say 3/2 and that's how me might normally say the cost of one watermelon... it's a $1.50 so the unit rate is 1.5 units.. and here the units are dollars

Answer:
The missing angle is 50 and x=6
Step-by-step explanation:
So if all three angles of a triangle add up to 180 degrees, you would simply subtract 180-70-60 to find the missing angle, and from there you put in the equation 8x+2=50, you would do a step by step process get the x by itself on one side. first subtract 2 from both sides to remove it from one, making the equation 8x=48 and than divide both sides by 8 to remove it from the x making the answer x=6. :3
Answer:
x=6
Step-by-step explanation:
Ok so to do this you need to know if you add up all the sides of a triangle [This is for triangles] you get 180 every time.
So you already have two given angels. 70 and 60.
Lets make it an equation.
70+60+8x+2=180
It looks long and hard but we can simplify this if we go ahead and add up all the common factors. In this case would be all the numbers with no variables.
132+8x=180
You don't add the 180 because its on the opposite side of the equation.
Now you need to get the variable alone. To do that you need to do the opposite operation. In this case, that would be subtraction
132(-132)+8x=180(-132)
8x=48
Divide the 8.
x=6
8(6)+2=50

write the fraction 32/40 in simplest form
Answer:
4/5
Step-by-step explanation:
32/40
Both can be divisible by 4
32 ÷ 4 = 8
40 ÷ 4 = 10
8/10
8 and 10 can be simplified again by 2
8 ÷ 2 = 4
10 ÷ 2 = 5
4/5
This cannot be simplified anymore, to check just divide.
32/40 = 0.8
4/5 = 0.8
The simplified form of 32/40 is 4/5.
How to simplify the fraction 32/40To simplify the fraction 32/40, we can find the greatest common divisor (GCD) of the numerator (32) and denominator (40) and divide both by that value.
The GCD of 32 and 40 is 8. By dividing both the numerator and denominator by 8, we can simplify the fraction:
32 ÷ 8 = 4
40 ÷ 8 = 5
Therefore, the simplified form of 32/40 is 4/5.

The growth between those years was about
Answer:
Greatest growth was between : year 3 and year 4
Percentage growth was about 32%
Step-by-step explanation:
Given the data:
Year : ______1 ____ 2 _____ 3 _______ 4
Students: __ 14 ___ 19 _____ 25 ______ 33
Number of students :
Year 1 & year 2 = 19 - 14 = 5
Year 2 & year 3 = 25 - 19 = 6
Year 3 & year 4 = 33 - 25 = 8
Hence,The two years at which the greatest growth was observed is between year 3 and year 4.
Percentage growth :
((33 - 25) / 25) * 100%
(8 / 25) * 100%
0.32 * 100%
= 32%
James and Sylvie need to paint the line around the outside of a soccer field. To know how much paint to buy, they must find the perimeter of the field. James claims, “I can calculate the perimeter by using the formula P = 2(l + w) .” Sylvie replied, “That’s not right. The correct formula is
P = 2l + 2w .” Who is correct? Provide evidence to support your answer.
Answer:
Both of them are correct.
The perimeter is found by adding up all four sides. If you notice, one of them is width and one of them is length. A rectangle has four sides, two width and two length.
l= length and w=width so P=2l+2w.
But, we can combine them by factorizing 2l+2w.
Lets see what we can pull out. We can only pull out 2.
2(l+w)=2l+2w.
2(l+w)=P
Both of them are correct.

Answer:
B
Step-by-step explanation:
Since ∠ E = ∠ F then the triangle is isosceles and DF = DE, that is
6x = x + 2y ( subtract x from both sides )
5x = 2y ( subtract 2y from both sides )
5x - 2y = 0 → (1)
and perimeter = 29, that is
6x x + 2y + 5x - y = 29 , simplifying
12x + y = 29 → (2)
Multiply (2) by 2
24x + 2y = 58 → (3)
Add (1) and (3) term by term to eliminate y, that is
29x = 58 ( divide both sides by 29 )
x = 2
Substitute x = 2 into (2) and evaluate for y
12(2) + y = 29
24 + y = 29 ( subtract 24 from both sides )
y = 5
Thus
FE = 5x - y = 5(2) - 5 = 10 - 5 = 5 → B
