Answer 1

Answer: Add to eliminate x

Step-by-step explanation:

So if you add to 2 equations you can look at it this way. remove all variables right that leaves you with 10+4=48 and -10-3=-56 right and if you add 10 and -10 you get 0 or 0x so by adding these to equations x is eliminated by adding

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.

(43 - 20) - 2 · 5

43 - 20 = 23

23 - 2 · 5

2 · 5 = 10

23 - 10 =

4) 81 ÷ (13 - 4)

13 - 4 = 9

81 ÷ 9

81 ÷ 9 =

5) 7 · 8 - 3 · 6 + 1

7 · 8 = 56

3 · 6 = 18

56 - 18 + 1

56 - 18 = 38

38 + 1 =

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

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

Answer:

C I think, im not sure but sorry if im wrong

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.

Answers

Answer:

30% are children.

Step-by-step explanation:

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,
