Answer:
x<10
Step-by-step explanation:
We can start off with adding 50.4x to both sides:
Once we do that we get the following: 43.2x < 432
If you notice, they both are almost the same number with the different of the decimal place. Lets multiply both sides by 10 to get rid of the decimal place:
432x < 4320
Now, if you see, they're basically the same number but the second place is x10 greater.
We can divide both sides by 432 and get x<10 as our answer!

Aluminum bronze consists of copper and aluminum, usually in the ratio of 10:1 by weight. If an object made of this alloy weighs 77 pounds, how many pounds of aluminum does it contain?
Answer:
The correct answer is (A). Copper and aluminum in the ratio of 10:1 means 10 parts copper to 1 part aluminum.
Step-by-step explanation:
7 pounds of aluminum in aluminum bronze by by weight.
What is Ratio?Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.
What is percentage?The percentage is defined as the ratio expressed as a fraction of 100.
The percentage is denoted by sign of %.
For example, if XYZ scored 46% marks in his test, it means that he scored 46 marks out of 100. It is written as 46/100 in the fraction form and 46:100 in terms of ratio.
Aluminum bronze consists of copper and aluminum in the ratio of 10:1 by weight
The ratio of copper and aluminum in aluminum bronze = 10:1
Let, aluminum in aluminum bronze by weight = x pound
And copper in aluminum bronze by weight = 10x pound
Since object made of this alloy weighs 77 pounds
So, x + 10x = 77
11x = 77
x = 7
Hence, 7 pounds of aluminum in aluminum bronze by by weight

We know that mid - point of a line segment divides it into two equal parts, that is it divides the segment in the ratio of 1 : 1, so let's find the coordinates of the mid point of line segment joining points (-9 , 3) and (5 , 7).
let the coordinates of the points be x and y, now
[tex]m = 1[/tex][tex]n = 1[/tex][tex]x_2 = 5[/tex][tex]x_1 = - 9[/tex][tex]y_2 = 7[/tex][tex]y_1 = 3[/tex]Using section formula :
value of x :
[tex]x = \dfrac{mx_2 - nx_1}{m + n} [/tex][tex]x = \dfrac{(1 \times 5) - (1 \times - 9)}{1 + 1} [/tex][tex]x = \dfrac{5 - ( - 9)}{2} [/tex][tex]x = \dfrac{5 + 9}{2} [/tex][tex]x = \dfrac{14}{2} [/tex][tex]x = 7[/tex]value of y :
[tex]y = \dfrac{my_2 -ny_1 }{m+ n} [/tex][tex]y = \dfrac{(1 \times 7) - (1 \times 3)}{1 + 1} [/tex][tex]y = \dfrac{7 - 3}{2}[/tex][tex]y = \dfrac{4}{2} [/tex][tex]y = 2[/tex]So, coordinates of the point which is midpoint of the given line is :

i dont know the answer to this question
Answer:
- 9°C is less than -4°C
Step-by-step explanation:
The reason that why these temperatures are related because when we start counting the numbers from left, it becomes smaller. For ex- 3 is on the left of 5. So, 3 is smaller than 5. That's how when we start counting from the left in negative numbers, the negative numbers gets smaller.
Hey can anyone help with this question please and thank you
Answer:
(7x-4)°= (3x+28)°. ( :. m || n, so it is alternate angle)
7x° - 4° = 3x° + 28°
4x° = 32°
x = 32/8
x = 4°
Answer:
x = 8
Step-by-step explanation:
< (7x - 4)° and < (3x + 28)° are Alternate interior angles that do not have a common vertex on alternate sides of the transversal, t. Therefore, they have the same measure.
We can establish the following equality statement to solve for x :
< (7x - 4)° = < (3x + 28)°
Subtract 3x from both sides:
7x -3x - 4 = 3x - 3x + 28
4x - 4 = 28
Add 4 to both sides:
4x - 4 + 4 = 28 + 4
4x = 32
Divide both sides by 4 to solve for x:
4x/4 = 32/4
x = 8.
To verify whether the value of x is correct, substitute x = 8 into the equality statement:
< (7x - 4)° = < (3x + 28)°
< [(7(8) - 4]° = < [3(8) + 28]°
< (56 - 4)° = < (24 + 28)°
< 52° = < 52° (True statement. Therefore, the correct answer is x = 8).

for the function R(x)= x+4/x-3, find the values of x that make the function less than or equal to 0
Answer:
-4[tex]\leq[/tex]x<3
Step-by-step explanation:
1)Break this into 2 case, equal to 0 and and less than 0.
2)The number equals zero if its numerator is 0 which happens when x=-4.
3) A fraction is less than 0 it is negative. Negative fractions are either +/- or -/+, so we have two subcases.
3a) For +/- the numerator is positive when x>-4 and denominator is negative when x<3. Putting those two together we have -4<x<3.
3b)For -/+ the numerator is negative when x<-4 and the denominator is positive when x>3 however those two values don't overlap.
4) Putting this together we have -4[tex]\leq[/tex]x<3

A machine can blow up 20 balloons in 4 min.
How many balloons can it blow up in 60 min?
Answer:
120
Step-by-step explanation:
all you have to do is multiply 20*60
Answer:
The machine can blow up 300 balloons in 60 min.
Step-by-step explanation:
60 ÷ 4 = 15. 15 x 20 = 300. We know it takes 4 minutes to blow up 20 balloons. 4 minutes is only 1/15 of 60, so that means you have to blow up 20 balloons 15 times, which will take 60 minutes, and in that 60 minutes, you blew up 300 balloons.
