Combine any like terms in the expression 4a + a​

Answers

Answer 1
4a is the same as adding "a" to itself 4 times.

So, 4a = a + a + a + a

Since 4a and a both have the term "a" in them,

4a + a = a + a + a + a + a

Since there are 5 a's on the right side, this can be combined to simplify,

4a + a = a + a + a + a + a
= 5a

Answers

Answer:

the first one is 57

the second one is 60

3rd one is 13

4th one is 9

Step-by-step explanation:

hope this helps :) have a nice day !!

**please let me know if this was wrong**

Answer:

1) In the second step, it was supposed to multiply 9 and 2 and 36 by 3 instead of adding 9 and 3 to each other because multiplication and division comes before adding, according to pemdas.  

2) In the second step, they were supposed to multiply 6 and 4 instead of subtracting 27 and 6 because multiplication comes before subtraction, according to pemdas.

3)

(43 - 20) - 2 · 5

43 - 20 = 23

23 - 2 · 5

2 · 5 = 10

23 - 10 =

13

4) 81 ÷ (13 - 4)

13 - 4 = 9

81 ÷ 9

81 ÷ 9 =

9

5) 7 · 8 - 3 · 6 + 1

7 · 8 = 56

3 · 6 = 18

56 - 18 + 1

56 - 18 = 38

38 + 1 =

39

6)

7)

8)

Step-by-step explanation:

Section 1: Explain the error in each problem below.

1) Pemdas says multiplication and division comes before adding, so you must solve the multiplication in the problem first before the addition.  

2) Again, as pemdas says, multiplication comes first before subtraction, so you must solve the multiplication in the problem first before the sutraction.

Section 2: Simplify the following expressions.

3) (43 - 20) - 2 · 5

Pemdas says to solve the parenthesis first.

43 - 20 = 2323 - 2 · 5

Now multiplication comes next (because there's no exponents).

2 · 5 = 1023 - 10

Now subtraction.

23 - 10 = 13

4) 81 ÷ (13 - 4)

Pemdas says to solve the parenthesis first.

13 - 4 = 981 ÷ 9

Now division comes next.

81 ÷ 9 = 9

5) 7 · 8 - 3 · 6 + 1

Pemdas says to solve the multiplication first.

7 · 8 = 56 3 · 6 = 1856 - 18 + 1

Now subtraction and addition.

56 - 18 = 3838 + 1 = 39

6)

Section 3: Insert grouping symbols to make the statements true.

Answer:

Step-by-step explanation:

Answer:

Graph B.

Step-by-step explanation:

Graph A. is too low and graph C. is too steep.

Also we know that 3/2 is equal to 1.5. This means that it will be a little more than y = x. So if we look at point (2,2), the line is not at that point, but the line is a little higher.

in a city 30 °/• are female and 40°/. are males . what are remaining children​

Answers

Answer:

30% are children.

Step-by-step explanation:

Females = 30%

Males = 40%

Therefore, children = 100% (total) - 30% + 40%

100 - 70

30%

QUESTION:

in a city 30 °/• are female and 40°/. are males . what are remaining children?

SOLUTION:

Given,

▶️ percentage of females = 30%

▶️ percentage of males = 40%

▶️ let the percentage of children be x.

Now,

▶️ x = 100% (total population) - 30% + 40%

▶️ x = 100% - 70%

▶️ x = 30% (Children population)

ANSWER:

The population % of children in a city is 30%.
