Answer:
300
Step-by-step explanation:
3 : 15 :: 60 : x
Product of extremes = Product of means
3 * x = 15 * 60
[tex]x = \frac{15 * 60}{3}\\\\x = 5*60\\\\x = 300[/tex]
Or Do in this way
[tex]\frac{3}{15}=\frac{60}{x}\\\\[/tex]
[tex]\frac{3*20}{15*20}=\frac{60}{x}[/tex]
x = 15* 20 = 300
Answer:
300
Step-by-step explanation:
Solve for A.
BA + C = D
1)A = D-B-C
2)A = (D-C)/B
3)A = (C - D)B

Find the solution of the system of equations -7x-3y=-20 3x+6y=-15
9514 1404 393
Answer:
(5, -5)
Step-by-step explanation:
I like a graphing calculator for quickly finding a solution to a system of equations. It shows the solution to be (5, -5).
__
We can add the second equation to 2 times the first to eliminate the y-variable.
2(-7x -3y) +(3x +6y) = 2(-20) +(-15)
-11x = -55 . . . . . collect terms
x = 5 . . . . . . . . . divide by -11
Substituting this value into the second equation, we have ...
3(5) +6y = -15
6y = -30 . . . . . . . . subtract 15
y = -5 . . . . . . . . . . divide by 6
The solution is (x, y) = (5, -5).
Solve for x 6 = 2( x + 0)

Jo sold 132 mugs. One quarter of the mugs were small. The rest were large. How many small mugs did Jo sell? * 1 point
Answer:
33 small mugs
Step-by-step explanation:
Given:
Total number of mugs sold by Jo = 132
One quarter of the mugs were small. The rest were large.
To find: Number of small mugs sold by Jo
Solution:
Number of small mugs sold by Jo = [tex]\frac{1}{4}[/tex] (Total number of mugs sold by Jo)
Therefore,
Number of small mugs sold by Jo [tex]=\frac{1}{4}(132)=33[/tex]

hi!!! what’s the area and formula for this problem??
Answer:
134.28 m²
Step-by-step explanation:
I suppose this is an isosceles triangle
tan 75° = 2 + √3 = 3.73 = h / 6 (h: height and 6 = 12/2, 1/2 of base)
h = 6 x 3.73 = 22.38
Area = (12 x 22.38) / 2 = 134.28

It took the football team 5 h to travel from Titletown, a total distance of 1320 km. Part of the trip was by bus and the remainder by plane. The bus averaged 40 km/h and the plane 600 km/h. How many hours were spent travelling by bus?
Answer:
It took 2 hours by plane
Step-by-step explanation:
let bus is represented by x and plane is represented by y
the total distance of bus and plane will be represented by equation:
40 x + 600 y = 1320 (1)
the total time taken by bus and plane will be represented by:
x + y = 5 (2)
solving equations (1) and (2) simultaneously:
Multiply by 40 on both sides in eq (2) and then subtract (1) and (2)
40 x + 600 y = 1320
40 x + 40 y = 200
_______________
560 y = 1120
y = 1120/ 56
y= 2
since plane is represented by y so, the time they spent travelling by plane is 2 hours.

Answer:
I believe the answer would be A.
Step-by-step explanation:
You can get rid of B. and C. since it is in the middle. The highest would be at the top/right side and the lease would be at the bottom/left side. Then the total score does not make much sense because you would have to add up every number

How does collecting like terms in an expression differ from collecting like terms in
an equation/inequality? Explain.
Answer:
I think its different from each other because maybe combining like terms in a inequality your trying to compare them? Or maybe they're just advanced. Can someone give me an example of an inequality please so I can try finding out the difference?

What is the solution to
-10 = 5(2x – 4)
Answer:
3=x
Step-by-step explanation:
multiply 5 times 2x and 4 which is 10x-20
then you have -10=10x-20
then add 20 to both aides and you'll have
30=10x then divide by 10 to get x alone
and you have
3=x
