When you start out solving this, you don't know what the number is, but you still need a name to call it. You can use any name you want when you do it, like 'x', 'y', 'z', 'Q', or 'Stewy'.

Right now, the one solving it is me, so I can use any name I like. I like "Ralph". Until I figure out what the unknown number really is, I'm calling it 'Ralph'.

The quotient of the number and 3 . . . . . (Ralph / 3)

The negative of 8 . . . . . -8

But the question says that these are equal, so you can write

Ralph/3 = -8 . <== This is the equation that the question is asking for.

How to solve it, and find out what number Ralph really is:

Take the equation . . . . . Ralph/3 = -8

Multiply each side by 3: (Ralph/3) x 3 = (-8) x 3

Simplify that . . . . . Ralph = -24

<u><em>Explanation</em></u>: For this question you need to write the mathematical equation step-by-step:

The quotient of a number and 3 which means x/3

Is equal to the negative 8 which means =-8

Combine the two and you get x/3=-8

<u><em>Answer</em></u>: x/3=-8

<u><em>Explanation</em></u>: If you want to simplify it you multiply 3 on both sides

<u><em>Answer</em></u>: -24

Susie begins a new walking program with 600 m on the first.day . Each day she will increaseher walk by 300 m . How mang km will

AleksandrR [38]

Answer: 5.7 km

Step-by-step explanation: take first day as day 1

day 1, she walked 600 m

day 2, she increased her walk by 300 m

that means, day 2 = 600 m + 300 m = 900 m

day 3, she increased her walk by 300 m again

that means, 900 m + 300 m = 1200 m

so we can deduce a formula to calculate her expected walk for the remaining days

day n = initial distance + increased distance (n - 1)

where; n is the no. of day we are looking for

initial distance is the distance walked on day 1

increased distance is the distance added on each day

so, if day 3 = 600 m + 300 m (2) = 600 m + 600 m = 1200 m

∴ day 18 = 600 m + 300 m (17) = 600 m + 5100 m = 5700 m

now, we convert 5700 m to km.

1000m=1km

5700m= 5.7km

so, on 18 days, susie will walk 5.7 km

<h3>Answer:</h3>

9. 471.7 square units

10. 827.0 square units

<h3>Explanation:</h3>

If you're going to have someone else solve your problem for you, it is much quicker and easier to use an appropriate computer or graphing calculator app. (See the attached.)

9. There are at least a couple of ways to approach this. The law of sines can be used to find the length of another side. Given two sides and the angle between them, a formula gives area.

<em>Law of Sines</em>

... a/sin(A) = c/sin(C)

Multiplying by sin(C) gives

... c = sin(C)·a/sin(A) = 19·sin(64°)/sin(20°) ≈ 49.9301

The angle between sides a and c is B, which has the value ...

... B = 180° -A -C = 180° -20° -64° = 96°

Then the area of the triangle is ...

... Area = (1/2)ac·sin(B) = (1/2)(19)(49.9301)(0.994522) ≈ 471.737 ≈ 471.7

10. Heron's formula will give the area of a triangle from its side lengths.

... s = (a+b+c)/2 = (51+38+45)/2 = 67

... Area = √(s(s-a)(s-b)(s-c)) = √(67·16·29·22) = √683936 ≈ 827.004 ≈ 827.0
