<span>(-7w^2 - 2w - 1) - (-5w^2 + 3w - 2)
Take out of parenthesis according to the symbol outside of them. In this case it is a negative so everything in the parenthesis will be opposite of what it is.
-7w^2 - 2w -1 + 5w^2 - 3w +2
Combine like terms.
-2^2 - 5w + 1
^^^^^ That is your official answer.
You cannot continue to simplify because there are no like terms to simplify and it would just not make sense to further simplify. Hope this helps. :) </span><span>

The answer is "sugar= 200g, flour=600g, and butter=400g".

Step-by-step explanation:

$50\ g \ sugar = 15\ biscuits\\\\3 \times 50 \ g = flour \\\\150\ g = flour\\\\2 \times 50 \ g = butter \\\\ 100 \ g = butter\\\\\frac{60}{15} = 4\\\\ 4 \ \text{times as much}\\\\4 \times 50\ g = 200\ g \ of\ sugar\\\\4 \times 150\ g = 600\ g \ of\ flour\\\\4 \times 100\ g = 400\ g \ of\ butter\\\\$

What is (2y + 14.6m + 3.8) – (34.8m + 15.6 + 2y)

zhenek [66]

Answer:

-20.2m -11.8

Step-by-step explanation:

(2y + 14.6m + 3.8) – (34.8m + 15.6 + 2y)

Distribute the minus sign

(2y + 14.6m + 3.8) – 34.8m - 15.6 - 2y

I like to line them up vertically

2y + 14.6m + 3.8

– 2y -34.8m - 15.6

------------------------------

-20.2m -11.8

Simplify and find any restrictions<br> <img src="https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B9x%7D%20-%5Cfrac%7B6%7D%7B2x%5E2%7D" i

Simplified: $\frac{4}{9x} -\frac{3}{x^{2} }$

Restrictions: x CANNOT be 0 because then the denominator would become 0 and would not be possible

Tyrod needs at least $820 to buy the computer he wants. He has already saved $330. He earns $50 per lawn that he cuts. What is t

Ksju [112]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

The equation representing the given statement is ~

$50x + 330 \geqslant 820$

The least number of lawns that he can cut and buy the computer is 10 lawns ~

$\large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}$

Total savings should be greater or equal to $ 820 in order to buy the computer,

And his total savinga is equal to ~

Money he saved + money got from cutting lawns.

let's assume the lawns cut by Tyrod be x,

Money earned by cutting lawns is equal to

total number of lawns cut × $50

50x

total savings is equal to ~

330 + 50x

hence,

$50x + 330 \geqslant 820$

by solving for " x (number of lawns cut) " we get ~

$50x \geqslant 820 - 330$

$50x \geqslant 490$

$x \geqslant 490 \div 50$

$x \geqslant 9.8$

Hence, the least number of lawns he has to cut is the number that is greater than 9.8, which is

$10$

What is (1.2 x 10^-2) x (3 x 10^5)

liraira [26]

Answer:

B. 3.6 x 10^3

Step-by-step explanation:

(1.2 x 10^-2) x (3 x 10^5)

When we multiply terms with powers , we multiply the factors out front and add the exponents

a * 10^b * c* 10^d = ac * 10^(b+d)

(1.2 x 10^-2) x (3 x 10^5) = (1.2* 3) * 10^(-2+5)

= 3.6 * 10 ^3
