Answer:
7x = 35cm ; 2x = 10cm
Step-by-step explanation:
7x and 2x are the lengths
7x+2x=45
Then you take 7 + 2 = 9
so is gonna be 9x = 45
then you divide both side with 9
so is gonna be x = 5
Then you take 5 multiply 7 : 2
so 7 x 5 = 35cm
2 x 5 = 10cm

What is 8.478 in expanded form?
Answers
explanation: the 1000 expands form
The expanded form of the given number is 8×1+4×1/10×7×1/100+8×1/1000 (option c)
What is an expanded form of numbers?We break up a number according to its place value and expand it to show the value of each digit, this process is called the expansion of the numbers.
Given that, we are asked to find the expanded form of 8.478,
The expanded form is :-
8 = 1 place = 8×1
0.4 = 1/10 place = 4×1/10
0.07 = 1/100 place = 7×1/100
0.008 = 1/1000 place = 8×1/1000
Therefore,
8.478 = 8×1+4×1/10×7×1/100+8×1/1000
Hence, the expanded form of the given number is 8×1+4×1/10×7×1/100+8×1/1000 (option c)

13.) The leading scorer in your high school's hockey league finished the season with an average of 4 goals per game for 15 games. As the leagues
second leading scorer, you have an average of 4 goals per game for 14 games. You still have to play your last game. How many goals must you
score in the final game to overtake the leagues' leading scorer?
Answers
Answer:
5 goals
Step-by-step explanation:
4 goals per game for 15 games means a total of 60 goals in that season. You have 4 goals per game for 14 games meaning you have a total of 56 goals. To overtake the leading team you must score a minimum of 5 goals to become the leading scorer. (Double-check to make sure I am correct)
How come this person didn’t divide EVERYTHING on the left by 2? I thought you had to...
Answers
The short answer is that algebra doesn't work that way. You wouldn't divide *everything* by 2, but every term that contains a factor of 2.
In the expression
2 (6x - 1) + 2 (2x + 5)
both terms have a factor of 2 (the 2 out in front of them). They're the ones that get canceled when dividing by 2:
(2 (6x - 1) + 2 (2x + 5)) / 2 = 2/2 (6x - 1) + 2/2 (2x - 5)
… = 1 (6x - 1) + 1 (2x - 5)
… = (6x - 1) + (2x - 5)
and so on.
Looking ahead, it turns out that the equation is solved by x = 7. This makes 6x - 1 = 41 and 2x + 5 = 19. So the equation is saying that, if you make these replacements,
2×41 + 2×19 = 120
If you divide *everything* on the left by 2, you end up with fractions:
(2/2)×(41/2) + (2/2)×(19/2) = 41/2 + 19/2
but 41 + 19 = 60, so the end result would be 30, but that's not the same as 120/2 = 60.
Three numbers add up to 210. The second number is 10 more than the first and the third number is 3 times the first. Find the numbers by modelling the problem using an algebraic equation.
Answers
Answer:
I. First number, a = 40.
II. Second number, b = 50.
III. Third number, c = 120.
Step-by-step explanation:
Let the three numbers be a, b and c respectively.
Given the following data;
Translating the word problem into an algebraic equation, we have;
a + b + c = 210
b = a + 10
c = 3a
Substituting the value of b and c into the equation, we have;
a + a + 10 + 3a = 210
5a + 10 = 210
5a = 210 - 10
5a = 200
a = 200/5
a = 40
To find the value of b;
b = a + 10
b = 40 + 10
b = 50
To find c
c = 3a
c = 3*40
c = 120

Step-by-step explanation:
The answers for the given problem can be stated as, "The inequality that represents the different sentence is represented by option (D)."And, "The inequality that represents the sentences that are alike is represented by options (A), (B) and (C) respectively."
What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
The expression for inequality for all the options are written one by one as follows,
(A) k is less than or equal to -3.
=> k ≤ -3.
(B) k is no more than -3
=> k ≤ -3
(C) . k is at most -3
=> k ≤ -3
(D) k is at least -3
=> k ≥ -3
Hence, options (A), (B) and (C) represents like while (D) represents different inequality.
