3 0

Step-by-step explanation:

a) clearly, the sequence is created by subtracting 12 from one term to the next.

so, d = -12

a (= a1) = -5 (the first term is the start value)

the next 3 terms are then

-41, -53, -65

a28 = -5 + 27×-12 = -329

b) the sequence is created by adding 6 from term to term.

so, d = 6

a (= a1) = 8

the next 3 terms are

26, 32, 38

a77 = 8 + 76×6 = 464

To answer this question you would need to solve this inequality. The first step would be to combine all three terms on the left-hand side of the greater than symbol. By doing this you would have 50w > 250. To solve this inequality divide both sides by 50. The answer is w > 5. In words, this means the number of walnuts per spoonful is greater than five.

Shelby bought a 2-ounce tube of blue paint. She used 2/3 ounce to paint the water, 3/5 ounce to paint the sky, and some to paint
irina1246 [14]

Answer:

The amount of ounce used for paint is \frac{9}{15} ounce  

Step-by-step explanation:

used amount for water is \frac{2}{3} ounce.

used amount for sky is \frac{3}{5} ounce.

thus, the total amount used is \frac{2}{3} +  \frac{3}{5}

= \frac{19}{15}

Thus the total unused amount is 2 - \frac{19}{15} = \frac{11}{15} .

But the remaining amount is \frac{2}{15}.

Thus used amount for flag is \frac{11}{15} - \frac{2}{15}

= \frac{9}{15}

jekas [21]
Difference between average temperature and highest recorded = 49.44

Highest - Average = 49.44    Let it be H - A = 49.44

H - (-34.44) = 49.44

H + 34.44 = 49.44

H = 49.44 - 34.44 = 15

Highest recorded = 15°C.
