hi <3

it would be option A and option C, i believe.

hope this helps :)

Answer:

[tex] \frac{5}{3} {a}^{2} b + \frac{3}{4} abc + 5 \\ \\ \frac{5}{3} ( { - 2)}^{2} (1) + \frac{3}{4} ( - 2)(1)(2) \\ \\ \frac{5}{3} (4) + \frac{3}{4} ( - 4) \\ \\ = \frac{20}{3} - 3 \\ \frac{20 - 9}{3} = \frac{11}{3} = 3.666[/tex]

Answer:

.375 or 6/16

Step-by-step explanation:

When you flip a coin you have 50/50 chance for it to land on heads or tail, assuming its not weighted or a trick coin.

Do this 4 times and the chances are now slimmer due to the amount of times it was flipped. In this case the probability of of you getting tails every time if you flip the coin 4 times is now .375 chance or 6/16. Here's the link to my work in a tree diagram

Answer:

D. 2¹⁵/4¹⁰

Step-by-step explanation:

(2³/4²)⁵ = 1/64

A. 2⁸/4⁷ = 1/128

B. 2⁵/4⁴ = 1/16

C. 2⁶/4⁶= 1/128

D. 2¹⁵/4¹⁰= 1/64

SO (2³/4²)⁵ = 2¹⁵/4¹⁰

Answer:

Peter = 6 kg

Mary = 12 kg

Lucy = 8 kg

Step-by-step explanation:

let us take number of kg's peter took as x

then lets form an expression to find x

let us take mary's chestnuts as = 2x (twice as much as peter)

let us take Lucy's chestnuts as = 2 + x (picked 2 kg more than peter)

so

x + 2x + 2+ x = 26

4x + 2 = 26

4x = 26 - 2

4x = 24

x = 24/4

x = 6

now let us see how much each of them picked while replacing 6 by x

Peter = x

         = 6 kg

Mary = 2x

         = 2(6)

         = 12 kg

Lucy = 2+x

        = 2 + 6

        = 8 kg

now let us cross check to see the answer

6 + 12 + 8

18 + 8

= 26

Hello :D

10% of 1135 = 1135/10 = 113.5

5% of 1135 = 113.5/2 = 56.75

15% of 1135 = 113.5 + 56.75 = 170.25

Answer:

[tex]y=-50[/tex]

Step-by-step explanation:

[tex]-\frac{y}{5}+4=14[/tex]

⇒ Subtract 4 from both sides:-

[tex]-\frac{y}{5}+4-4=14-4[/tex]

[tex]-\frac{y}{5}=10[/tex]

⇒ Multiply both sides by 5:-

[tex]5\left(-\frac{y}{5}\right)=10\cdot \:5[/tex]

[tex]-y=50[/tex]

⇒ Now, divide both sides by -1:-

[tex]\frac{-y}{-1}=\frac{50}{-1}[/tex]

[tex]y=-50[/tex]

8k - 9(4k + 4) = 8k - 36k - 36 = -28k - 36

Let's rewrite in the simplest term,

→ 8k - 9(4k + 4)

→ 8k - 36k - 36

→ [-28k - 36]

The simplest term is -28k - 36.
