Add and subtract as normal however just make sure you are always moving the decimal point in the right place.

Answer:

Write down the numbers, one under the other, with the decimal points lined up.

Put in zeros so the numbers have the same length (see below for why that is OK)

Then add using column addition, remembering to put the decimal point in the answer.

There are (43)2⋅ 40 strawberries on a farm. What is the total number of strawberries on the farm?

Kazeer [188]

Answer:

3,440 strawberries

Step-by-step explanation:

Because of PEMDAS you want to start with the parentheses, and want to treat them like the distributive property.

So,

43 x 2 = 86

Then,

86 x 40 = 3440.

I hope that helps!!

What three consecutive numbers have a sum of 126

Leno4ka [110]

Answer:

41, 42, 43

Step-by-step explanation:

three consecutive numbers

$x + (x+1) + (x+2)$

have a sum of 126

$x + (x+1) + (x+2) = 126\\x + x + 1 + x + 2 = 126\\3x + 3 = 126\\3x = 123\\x = 41$

41 is our smallest number, so 42 and 43 are the two other numbers

Note: With these sum of N consecutive numbers problems, you can find the middle number by doing (Sum/N)

Can someone help me 1 or 4

sleet_krkn [62]

Answer:

No. 1: y = 90 (vertically opposite angles)

Also, x = 9. To find x, we'll have:

$3x + 7 + 56 + 90 = 180 \\ (sum \: of \: angles \: on \: a \: straight \: line) \\ 3x + 153 = 180 \\ 3x = 180 - 153 \\ 3x = 27 \\ \frac{3x}{3} = \frac{27}{3} \\ x = 9.$

No. 4: y = 62 (vertically opposite angles)

Also, x = 12. To find x, we have:

$5x = 60 \\ \frac{5x}{5} = \frac{60}{5} \\ x = 12.$
