Answer:
249x + 1y = 250
Step-by-step explanation:
Answer:
5x + 2y = 250 pencils
Step-by-step explanation:
5 represents the amount in each small box.
2 represents the amount in each large box.
Therefore once you multiply by 5 and x, then multiply by 2 and y you should get the total amount of pencils for the pencils in small boxes and the amount for large sepretally. Then you'd add both of the digits to get the total pencils in all
The lengths of two sides of a triangle are given. Find the range of possible lengths for the third side.
6 ft, 6 ft
The range of the third side is < x < .
Answer:
0 < x < 12
Step-by-step explanation:
According to the triangle inequality theorem, the sum of the two sides must be greater than the length of the third side. 6+6 = 12
0 < x < 12
The total surface area of a cube is 96cm2, find its volume.
Answer:
[tex]\huge\boxed{V=64cm^3}[/tex]
Step-by-step explanation:
The formula of a surface area of a cube:
[tex]SA=6a^2[/tex]
The formula of a volume of a cube:
[tex]V=a^3[/tex]
We have
[tex]SA=96cm^2[/tex]
Calculate the edge length (a).
[tex]6a^2=96[/tex] divide both sides by 6
[tex]a^2=16\to a=\sqrt{16}\\\\a=4(cm)[/tex]
Calculate the volume of a cube:
[tex]V=4^3=64(cm^3)[/tex]

Answer:
3^2*3^4
3^12/3^4
(3^4)^2
The first, fourth, and fifth
Step-by-step explanation:
Follow rules of exponents
When multiply an exponent with same base just add the exponents
EX: 2^2 * 2^2= 2^4
When dividing with the same base, subtract
EX: 3^12/3^2=3^10
When raising the power of an exponent to another exponent, multiply.
EX: (3^2)^2=3^2
Answer:
The correct answer to your problem is
[tex]3^{2} * 3^{6} \\\\\frac{3^{12} }{3^{4}} \\\\(3^{4})^{2}[/tex]
Step-by-step explanation:
You can think of the exponets as it's own number's.
For example the first answer ([tex]3^{2} * 3^{6}[/tex]) 6 + 2 = 8 so your answer [tex]3^{8}[/tex].
The next one [tex]\frac{3^{12} }{3^{4} }[/tex] you would divide 12 by 4 and get 8 giving the answer [tex]3^{8}[/tex].
And finally the last one [tex](3^{4})^{2}[/tex] if you mutiply the exponets 4 and 2 you would get 8 so you answer would be [tex]3^{8}[/tex].

Dani is training for a marathon. Her target speed is 25 miles per hour. She currently runs 15 miles in 1/2 an hour. Does she achieve her target speed for her run?
Answer:
target speed for the marathon has been achieved and exceeded
Step-by-step explanation:
Given that :
Target speed = 25 mph
Current speed = 15 miles in 1/2 an hour
Current speed :
15 miles in 0.5 hours
X miles in 1 hour
0.5x = 15 miles
X = 15 / 0.5
X = 30 miles per hour
Hence, current speed in miles per hour = 30mph
This means that her target speed for the marathon has been achieved and exceeded

Lewis walked 9/10 of a mile. His friend walked 2/5 of the way with him. How many miles did Lewis's friend walk with him?
Answer:
Lewis's friend walked with him 9/25 miles
Step-by-step explanation:
Given that
Lewis walked 9/10 of a mile
And His friend accompanied him on 2/5 of the way.
This is a simple question of fraction multiplication
The fraction 2/5 has to multiplied with the miles walked by lewis
So
[tex]= \frac{2}{5} * \frac{9}{10}\\=\frac{9}{25}[/tex]
Hence,
Lewis's friend walked with him 9/25 miles

Algebra...George bought 2 identical couches and 3 identical chairs. A couch cost twice as much as a chair. He spent $270 more on th ecouches than on the chairs. How much did he spend altogether
Answer:
$1890
Step-by-step explanation:
x= couches
y=chair.
x=2y
2x=3y+270
2(2y) or 4y=3y+270
y=270
x=540
2(540)+3(270)=1890.
Hope this helps :D

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
George bought 2 identical couches and 3 identical chairs.
A couch costs twice as much as a chair.
Let the cost of one couch = 2x
Let the cost of one chair = x
Now,
He spent $270 more on the couches than on the chairs.
This means that,
2(2x) = 270 + 3x
4x = 270 + 3x
Subtract x on both sides.
x = 270
The total spending.
= 4x + 3x
= 4 x 270 + 3 x 270
= 1080 + 810
= $1890
Thus,
The total spending is $1890

Jordan is buying plastic plates for a party.The plates usually cost $2.40 per 10 plates,but they are on sale for 30% off usual price.If jordan buys 50 plates,how much will they cost
30% off means they are paying 70% of the original price.
Sale price = 2.40 x 0.70 = $1.68 for 10 plates
50 plates / 10 = 5
They buy 5 packages of plates.
1.68 x 5 = $8.40
Total price = $8.40
Answer:
Step-by-step explanation:
2.40 X 5 =$12
12 X 0.3=$3.6 off
12-3.6=$8.40
Therefore it'll cost $8.40

Factorize
The options are not given; So, I'll answer on a general term
[tex]-3x - 9[/tex]
Express -9 as -3 * 3
[tex]-3x - 9 = -3x - 3 * 3[/tex]
Then factorize 3 out of the expression as:
[tex]-3x - 9 = 3(-x - 3)[/tex]
Another way is to factor -3 out of the expression as:
[tex]-3x - 9 = -3x - 3 * 3[/tex]
[tex]-3x - 9 = -3(x + 3)[/tex]
The width of a painting is 4 inches less than the length. The frame that surrounds the painting is 2 inches wide and has an area of 240 square inches. What are the dimensions of the painting? (Hint: The total area minus the area of the painting alone is equal to the area of the frame.)
Answer:
131 in²
Step-by-step explanation:
Let x represent the length of the painting. Given that The width of a painting is 4 inches less than the length. Hence:
Width = x - 4
The area of painting = length * width = x(x - 4) = x² - 4x
The frame that surrounds the painting is 2 inches wide (at the top and bottom, left and right). Hence the total width of the frame = (x - 4) + 2 + 2 = x, the length of the frame = x + 2 + 2 = x + 4
The area of the frame = length * breath = x(x + 4) = x² + 4x
Given that the area of the frame = 240 in², hence:
x² + 4x = 240
x² + 4x - 240 = 0
x = -17.62 and x = 13.62
Since the length cannot be negative, hence length = x = 13.62 inches
Area of painting = x(x - 4) = 13.62(13.62 - 4) = 131 in²
solve the equation -7(2m-6) + 21=-77
THIS IS FOR 20 POINTS DUE IN 10 MINUTES
TROLL ANSWER WILL GET REPORTED
Answer:
m=10
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−7(2m−6)+21=−77
(−7)(2m)+(−7)(−6)+21=−77(Distribute)
−14m+42+21=−77
(−14m)+(42+21)=−77(Combine Like Terms)
−14m+63=−77
−14m+63=−77
Step 2: Subtract 63 from both sides.
−14m+63−63=−77−63
−14m=−140
Step 3: Divide both sides by -14.
-14m/-14=-140/-14
m=10
Answer:
m =10
Step-by-step explanation:
-14m+42+21=-77
-14m+63= -77
-14m= - 140
m=10

Mai and Tyler work on the equation 2/5 b + 1 = -11 together. Mai’s solution is b= -25 and Tyler’s is b = -28 Here is their work. Do you agree with those solutions?
Mai: Tyler:
2/5 b + 1 = -11 2/5 b + 1 = -11
2/5 b = -10 2b + 1 = -55
b = -10 • 5/2 2b = -56
b = - 25 b = -28
Answer:
I disagree with both solutions. The value of b that will make the expression correct is -30
Step-by-step explanation:
Given the equation solved my Mai and Tyler expressed as:
2/5 b + 1 = -11
We are to check the veracity of the solutions;
2/5 b + 1 = -11
Subtract 1 from both sides of the expression
2/5 b + 1 -1 = -11-1
2/5 b = -12
Cross multiply
2b = -12 * 5
2b = -60
Divide both sides by 2
2b/2 = -60/2
b = -30
Since the solution b = -25 and -28 does not tally with the gotten solution, I disagree with the both solutions
