Answer 2
Answer:

Answer:

1421235

Step-by-step explanation:

2 + 34233 = 34235 - 2943 = 31292 + 291 = 31583 x 45 = 1421235

2 + 34233 = 34235 - 2943 = 31292 + 291 = 31583 ➗ 45 = 701.844444444

If its multiplication the answer is = 1421235

If division the answer is = 701.844444444 (calculator) or 701 r 38 (my brain)

Question: 11.23 x 10 to the power of 5, the answer is 11.2300000.

Explanation: multiple 10 x 10 x 10 x 10 x 10 = 10,000, then multiple 11.23 x 10,000 = 112300000, add the decimal places = 11.2300000.

Question: 11/20 a repeating or terminating decimal,

Answer: is terminating.

Question: 7 * 73 + 43, the answer is 554.

Explanation: multiple 7 x 73 = 511 + 43 = 554. If division then divide 7 into 73 = 10.4285714286 + 43 = 53.4285714286 (calculator answer). 7 into 73 = 1 r 3 = 1.3 + 43 = 44.3 or 44 r 3 (my brain answer).

I know some of the questions arent part of the asked one, but the plataform didnt let me answer them any but here.

Ii dont understand how to solve a system of linear equations using the substitution method

Answers

so 8x-7y=-7
-16+12x=14
you can simplify the sceon equation
-8+6x=7
add 8 to both sides
6x=15
divide by 6
x=15/6
subssitute
8(15/6)-7y=-7
120/6-7y=-7
20-7y=-7
subtract 20
-7y=-27
divide by -7
y=27/7

x=15/6
y=27/7

72 raisin cookies sold of Ratio 9:1 to oatmeal cookies sold. How many cookies combined sold

Answers

•Find the amount of oatmeal cookies sold
Since the Ratio is 9:1
9=72 raisin cookies sold
1=? oatmeal cookies sold
Using cross multiplication
?=(72x1)/9=8
Hence, 8 oatmeal cookies were sold.
•Find the amount of combined cookies sold
72+8=80
So, a total of 80 cookies were sold.

What are the solutions to the equation x^2-8x=24

Answers

x^(2) - 8x = 24

Transposing the equation to give zero on the RHS:
x^(2) - 8x - 24 = 0

Since we can't factorise it directly, we must complete the square to yield any solutions:
x^(2) - 8x + ( (8)/(2))^2 - ((8)/(2))^2 - 24 = 0
(x^(2) - 8x + 16) - 16 - 24 = 0
(x-4)^2 - 40 = 0
(x-4)^2 = 40
x-4 = +/- √(40) ––> because square rooting yields a positive and negative solution.
x = 4 +/- √(40)
x = 4 +/- 2 √(10)

Correct me if I'm wrong anyone.
