Identify the value of x that makes each pair of ratios equivalent.

aleksley [76]

Answer:

c.1

Step-by-step explanation:

5: 15 x:3

a:b c:d The ratios have to stay in proportion. So if we multiply a and b by a certain number they will equal c and d. We just don't know what that number is yet. Call it something.

a* something = c and b* something =d

5 * something = x

15* something = 3

Solve for the unknown number we are multiplying by

Divide each side by 15

15/15 * something =3/15

something = 1/5

Now that we know what we are multiplying by, we can solve for x

So 5 * something = x

5* 1/5 = x

1 =x

What is the value of x? 27(x+4)=−6 −35 −25 25 35

Oksanka [162]

x = -38/9 !!!

27(x+4)=−6

Step 1: Simplify both sides of the equation.

27(x+4)=−6

(27)(x)+(27)(4)=−6 (Distribute)

27x+108=−6

Step 2: Subtract 108 from both sides.

27x+108−108=−6−108

27x=−114

Step 3: Divide both sides by 27.

27x/27=−114/27

x=−389

Find x using Pythagorean theorem

Veronika [31]

Answer:

24.4

Step-by-step explanation:

18 ÷ 2 = 9

26² = x² + 9²

x² + 81 = 676

x² = 676 - 81

x² = 595

x = √595

x ≈ 24.4

Cora is building towers of two different sizes using prism- and pyramid-shaped blocks. The diagram shows the ratio of prisms and

Musya8 [376]

There are 20 blocks needed for tower A, and 43.75 blocks needed for tower B

From the tape diagrams, we have the following ratio

Prism : Pyramid = 4 : 1

From the table, we have:

Tower A = 16 prisms

So, the ratio becomes

16 : Pyramid = 4 : 1

Multiply the ratio on the right-side by 4

16 : Pyramid = 16 : 4

By comparison, we have:

Pyramid = 4

This means that, 4 pyramid blocks are needed for tower A

So, the total number of blocks needed is:

Total = Pyramid + Prism

This gives

Total = 4 + 16

Evaluate the sum

Total = 20

Hence, there are 20 blocks needed for tower A

For table B, we have:

Tower A = 35 prisms

So, the ratio becomes

35 : Pyramid = 4 : 1

Express as fractions

$\frac{Pyramid}{35} = \frac 14$

Multiply through by 35

Pyramid = 8.75

This means that, 8.75 pyramid blocks are needed for tower B

So, the total number of blocks needed is:

Total = 8.75 + 35

Evaluate the sum

Total = 43.75

Hence, there are 43.75 blocks needed for tower B
