Answer:
-120
Step-by-step explanation:
(5)8x
(5)(8)(-3)
5(-24)
= -120
Hi! I'm happy to help!
To solve this, we just have to insert -3 for x. Because the 5 in parenthesis is next to the eight with no other sign, it represents multiplication. Since the eight is next to the x with no other sign, it also means multiplication.
(5)8x
(5)·8·x
We can remove the parenthesis.
5·8·x
5·8·-3
40·-3
-120
So, when x=-3, (5)8x evaluates to -120.
I hope this was helpful, keep learning! :D

Answer:
[tex]m=\displaystyle \frac{t-6}{3}[/tex]
Step-by-step explanation:
Hi there!
Let t equal the total number of muffins.
[tex]t-6[/tex] ⇒ This represents freezing the 6 muffins
[tex]\displaystyle \frac{t-6}{3}[/tex] ⇒ This represents sharing the remaining muffins among 3 people
Therefore, the expression would be [tex]\displaystyle \frac{t-6}{3}[/tex].
If you would like to change this into an equation, it would be [tex]m=\displaystyle \frac{t-6}{3}[/tex], where m is the number of muffins that each person gets.
I hope this helps!
If the digits A, B and C are added, the sum is the two-digit number AB as shown. What is the value of C?
A
B
+ C
______
AB
Answer:
C=9
Step-by-step explanation:
If A, B, and C are all single digits the mimimum sum for AB would be 10 as it is a two-digit number (or 11 if you do not consider 0 a digit)
AB-(A+B)=C
10-(1+0)=9 or 11-(1+1)=9
therefore C=9
12 only show work pls
Answer:
Step-by-step explanation:
Since the perimeter is 46, and opposite sides of a rectangle are equal, we know that
(x+2)+(x+2)+(2x+3)+(2x+3)=46
Combine like terms to get: 6x+10=46
Subtract 10 from both sides to get: 6x=36
Divide both sides by 6 to get: x=6.

Fractions, decimals, and percents are all used to describe a
part of something. Which of the 3 types do you think is most
commonly used? Why do you suppose this is true?
Answer:
Step-by-step explanation:
I think that Percents are used very commonly all around us every day. It gives us a better vision in our mind of the quantity than decimals or fractions. We see Percents everywhere. In the shopping mall for discounts, math homework and work. So overall, percents are most commonly used.

2(6a - 5) + 2(a + 1) =
= 12a - 10 + 2a + 2 =
= 12a + 2a - 10 + 2 = 14a - 8
Answer:
14a-8
Step-by-step explanation:
A perimeter is the sum of the length of each side. So we can find the perimeter by adding: (a+1)+(a+1)+(6a-5)+(6a-5).
Combine like terms to get: 14a+2-10 = 14a-8.
Without knowing what a is, the perimeter is 14a-8.
A cylinder has a volume of 100cm and a radius
of 5 cm. What is its height in centimeters? Leave
the answer in terms of .
Answer:
1.27cm
Step-by-step explanation:
Volume(v) =100 cm
Radius(r) =5cm
Height(h) =?
Now,
Volume of cylinder (v) =¶r^2h
100 =22/7*5*5*h
100=78.57h
H=100/78.57
H=1.27cm
Height of cylinder is 1.27cm
m - 4 = 2m
Check your solution if possible
Answer:
m - 4m = 2m
-4 = 2m -m
- 2 = m
Answer:
m = -4
Step-by-step explanation:
Add 4 to both sides of the equation
Simplify
Add the numbers
= 2 + 4
Subtract 2 from both sides of the equation
=2+4
−2=2+4−2
Simplify
Divide both sides of the equation by the same term

Calvin owns a toy store. He can spend at most $200 on restocking cars and dolls. A doll costs $6.50, and a car costs $8.00. Let x represent the number of cars, and let y represent the number of dolls. Identify an inequality for the number of toys he can buy. Then identify the number of dolls Calvin can buy if he buys 10 cars.
8x + 6.50y ≤ 200; no more than 19 dolls
8x + 6.50y ≤ 200; no more than 18 dolls
6.50x + 8y ≤ 200; no more than 19 dolls
6.50x + 8y ≤ 200; no more than 18 dolls
The required inequality expression is 8x + 6.50y ≤ 200
Maximum amount he can spend = $200
Cost of doll, = $6.50
Cost of car = $ 8.00
Mathematically, the maximum amount he can spend on restocking is cars and doll is :
(Cost of cars × number of cars) + (cost of doll × number of dolls) ≤ maximum amount
8x + 6.50y ≤ 200
Hence, the required inequality expression is : 8x + 6.50y ≤ 200

Please help me rq!! i need help
Answer:
x = 2
Step-by-step explanation:
The volume (V) of a cuboid is calculated as
V = lbh ( l is length, b is breadth, h is height )
Here l = 10x , b = [tex]\frac{7}{4}[/tex] , h = 2 , then
V = 10x × [tex]\frac{7}{4}[/tex] × 2 = 70 , that is
20x × [tex]\frac{7}{4}[/tex] = 70
5x × 7 = 70
35x = 70 ( divide both sides by 35 )
x = 2
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
Since L × W × H = V, we get
[tex]10x*\frac{7}{4}*2=70\\10x*\frac{7}{4}=35\\10x=20\\x=2[/tex]
