Lets say, I bought 3 cakes in the store and I spent $300, how much does a cake cost?
The equation representing that situation is the following, calling x the cake cost, our unknown factor:
3x = 300
we can solve this equation by dividing all equation by 3:
x = 100
therefore each cake costs $100

I want to buy eight bracelets, I don't know how much each bracelet costs, but the final cost will be $39.67.
The equation would look like this:
8 x <em>c</em> = 39.67
Where <em>c</em> equals cost.
To find the answer I would do the following:
8 x <em>c </em>= 39.67
<em>c</em> = 39.67 / 8
<em>c</em> ≈ 4.95
Each bracelet costs about $4.95.

Graph the line with slope<br> 2.<br> passing through the point (-3, 3).<br> 3<br> 1<br> ?<br> 13
Alekssandra [29.7K]

The graph of the line with the given slope that passes through (-3, 3) is shown in the image attached below.

<h3>What is the Equation of a Line in Slope-intercept Form?</h3>

The equation in slope-intercept form of a line, is y = mx + b, where:

b = y-intercept

m = slope = change in y/change in x.

Given a line with slope = 2 and passes through (-3, 3), plug in m = 2 and (a, b) = (-3, 3) into y - b = m(x - a) to write the equation of the line

y - 3 = 2(x - (-3))

Rewrite in slope-intercept form

y - 3 = 2x + 6

y = 2x + 6 - 3

y = 2x + 3

Therefore, the graph of the line with the given slope that passes through (-3, 3) is shown in the image attached below.

What is an example of a whole number?

Any positive number that does not contain a fractional or decimal component is referred to as a whole number. The numbers 0, 1, 2, 3, 4, 5, 6, and 7 are all whole numbers, for instance, as a result. -3, 2.7, or 3 12 are examples of non-whole numbers.

The closest perfect squares near 12 are 16 and 9 which are the perfect squares of 4 and 3 respectively Therefore the root of 12 lies between 3 and 4.

i.e  3 < √12 < 4

Find the circumference and area of each. Round to nearest tenth:
patriot [66]

№1. Given: r=8 ft, π≈3.14

C=2×π×r=2×3.14×8=50.24=50.2 ft

A=π×r²=3.14×64=200.96=201 ft²

Answer: 50.2 ft; 201 ft²

№2. Given: D=11 cm, π≈3.14

d=2r or r=2/d, so if d is 11 cm, then r is 11÷2=5.5 cm

C=2×π×r=πD=3.14×11=34.54=34.5 cm

A=π×r²=3.14×(5.5)²=94.985=95 cm²

Answer: 34.5 cm; 95 cm²
