What is the value of x in the equation below? 3x - 15 = 60
Answer:
3x=60+15
x=75/3
x=25
Thus the answer is 25
Answer:
[tex]3x - 15 = 60 \\ 3x = 60 + 15 \\ 3x = 75 \\ x = \frac{75}{3} \\ x = 25[/tex]

Can anyone help me with this math please I will give brainlist
Answer:
4.5 > 4.420
0.67 < 0.8
0.82 = 0.820
62.4 > 6.24
0.13, 0.3, 0.303, 0.32
0.08, 0.8, 0.82, 8.2
24.54, 24.4, 24.304, 24.24
6.5, 6.25, 6.05, 6.007
Step-by-step explanation:
The most useful way to compare fractions is to add extra zeros at the end.
For example, 0.67 ___ 0.80.
0.80 is obviously bigger than 0.67.
In 24.4, 24.54, 24.304, 24.24, you can add extra zeros as well.
24.400, 24.540, 24.304, 24.240 (This makes it much easier to group the numbers, whether from largest to smallest or smallest to larger).
**REMEMBER TO REMOVE THOSE ZEROS AFTER FINDING YOUR FINAL ANSWER**

The length of a football field is 120 yards from one and one to the other end zone.
Answer:
To solve, you need to use Pythagorean Theorum
a^2+b^2=c^2
100^2+53.33^2 = c^2
10,000+2844.0889=c^2
12844.1=c^2
square root
= 113 1/3 yards
So it is less than 120 yards
Step-by-step explanation:
Here's a primer on how the dimensions play out at every level, from high school football to the NCAA and on up to the NFL. There are two constants, across the level of competition: 120 yards (360 feet) of length and 53 1/3 yards (160 feet) of width.

Answer:
63
Step-by-step explanation:
If you put them from least to greatest order you cross out from both ends until you get to the middle, in that case I got to the middle in between 63 and 63 so you can go in between them so your answer is 63

What is the largest two-digit number that is a multiple of 21?
Answer:
84
Step-by-step explanation:
Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks. Tori hosts a podcast about computers, and Wendy hosts a podcast about parenting. Both podcasts have a set duration for each episode. Last year, Tori released 40 episodes and Wendy released 16 episodes, for a total of 5,584 minutes of content. This year, Tori released 27 episodes and Wendy released 11 episodes, which lasted a total of 3,795 minutes. How long is each episode? Each episode of Tori's podcast is minutes long, and each episode of Wendy's podcast is minutes long.
Answer:
x = minutes of Tori's podcast = 88 minutes
y = minutes of Wendy's podcast = 129 minutes
Step-by-step explanation:
Let
x = minutes of Tori's podcast
y = minutes of Wendy's podcast
40x + 16y = 5,584 (1)
27x + 11y = 3,795 (2)
Multiply (1) by 11 and (2) by 16
440x + 176y = 61,424 (3)
432x + 176y = 60,720 (4)
Subtract (4) from (3) to eliminate y
440x - 432x = 61,424 - 60,720
8x = 704
x = 704/8
x = 88
Substitute x = 88 into (1)
40x + 16y = 5,584 (1)
40(88) + 16y = 5,584
3,520 + 16y = 5,584
16y = 5,584 - 3,520
16y = 2,064
y = 2,064/16
y = 129
x = minutes of Tori's podcast = 88 minutes
y = minutes of Wendy's podcast = 129 minutes

Triangle to the left I did 4 x 3 = 12 ÷ 2 =6
Triangle to the right I did 2 x 4 = 8 ÷ 2 = 4
Then I did square in the middle so 5 x 4 = 20
Now i add these up 20 + 6 + 4 = 30

Step-by-step explanation:
A motorboat averages 20 miles per hour (mph) in still water. It takes the boat the same amount of time to travel 3 miles with the current as it does to travel 2 miles against the current. What is the current's rate in mph?
Answer:
4 mph
Step-by-step explanation:
Let :
Boat speed = 20 mph
speed of current = x mph
Distance against current = 2 miles
Distance with current = 3 miles
speed against current will be ; 20 - x
speed with current will be ; 20 + x
Time =distance / speed against time against = time with current
Solving Mathematically ;
2/(20-x )=3/(20 +x)
2(20+x )= 3( 20-x )
40+2x = 60-3x
3x +2x=20
5x=20
x = 20 / 5
x = 4 mph
Speed of current = 4 mph

There were x cupcakes at the beginning of a party. By the end of the party, 16 of them had been eaten. Using x, write an expression for the number of cupcakes that were left.
Answer: x - 16
Step-by-step explanation:
Since there were x cupcakes at the beginning of a party and at the end of the party, 16 of them had been eaten, the expression for the number of cupcakes that were left will be gotten by subtracting the number of cupcake that have been eaten from the cupcakes at the beginning. This will be:
= x - 16
For example, if there were 20 cupcakes at the beginning and 16 was eaten, the number left will be:
= x - 16
= 20 - 16.
= 4
There'll be 4 left

If two sides of a triangle measure 4 cm and 6 cm what could be the measure of the third side? A. 9 B. 10 C. 11 D. 12
Answer:
A. 9
Step-by-step explanation:
Triangle Inequality: the lengths of any two sides of a triangle add up to more than the third side.
B. 10 can't be the answer because the 4 cm and 6 cm sides would just meet at a point on the 10 cm sides.
C. 11 and D. 12 can't be answers because the 4 cm and 6 cm sides would not meet (kind of like windshield wipers that are too short).
How to solve this equation?
It says use the substitution method, so you would take the bottom equation, and since it says that x is equal to that, you would use that equation in place of the x in the top equation. so it would be 9y = 3(3y+3) - 9. You then distribute the 3 into the 3y +3, which gets you 9y = 9y + 9 - 9, which is also 9y=9y. Subtract 9y to get 0 = 0, which just means that there are infinite solutions to this equation. Whenever you get 0 = 0, all that means is that there are infinite solutions to this particular set of equations. Hope this helped!
Answer:
y=y
x=3y+3
Step-by-step explanation:
[tex]\left \{ {{9y=3x-9} \atop {x=3y+3}} \right.[/tex]
[tex]9y=3x-9[/tex]
Plug the second equation [tex]x=3y+3[/tex] into the above equation as x
[tex]9y=3(3y+3)-9[/tex]
Open up the brackets
[tex]9y=3(3y+3)-9\\9y=9y+9-9\\9y=9y\\y=y[/tex]
This system of equations has infinitely many solutions.
When graphed, the two lines will overlap each other.
Therefore, y=y and x=3y+3.
I hope this helps!

REPOST!!!!!! 20 POINTS!!!!!!
A, B, and C are points of tangency in the given Circle, a m equals 6, BK equals 4 in the perimeter of mkn is 34
Answer:
A
Step-by-step explanation:
according to tangent property
we get
AM=BMAN=CNBK=CKGiven that
AM=6BK=4Thus our equation is
[tex] \rm \displaystyle 2AM + 2AN + 2BK = 34[/tex]
substitute the given values
[tex] \rm \displaystyle 2.6+ 2AN+ 2.4 = 34[/tex]
simplify multiplication:
[tex] \rm \displaystyle 12+ 2AN+ 8 = 34[/tex]
simplify addition:
[tex] \rm \displaystyle 2AN+ 20= 34[/tex]
cancel 20 from both sides:
[tex] \rm \displaystyle 2AN=14[/tex]
divide both sides by 2:
[tex] \rm \displaystyle AN=7[/tex]
AN=CN
hence,CN=7
therefore our answer is A

Answer:
3 - 151 x
Step-by-step explanation:
d/dx(5×3 x - 10×15 x - 3 x - 10 x - (3 x - 3)) = -151
Indefinite integral:
integral(3 - 151 x) dx = 3 x - 75.5 x^2 + constant
Definite integral after subtraction of diverging parts:
integral_0^∞ ((3 - 151 x) - (3 - 151 x)) dx = 0

I’m not smart so help me please get it right
Answer:
Surface area = 148cm^2
Volume = 120cm^2
Step-by-step explanation:
You are smart don't say you're not. :)
Answer:
Surface Area is 148 cm^2
Your Volume will be 120 cm ^3
Step-by-step explanation:
Surface Area you get by getting the area of each of the 2 dimensional shapes, the formula to get the surface area for a rectangualr prism is 2(wl+hl+hw), so you would plug in 2((5(6))+((4(6))+(4(5)) which will give you 2((30)+(24)+(20)) which will then give you 2(74) and the final answer will be 148 cm^2
The formula for Surface Area is w(l)(h) so in this case it will be 5(6)(4) which will be 30(4)= 120 cm^3
Hope this helps
