8 0

Answer:

Step-by-step explanation:

2) 8=n+3/-2

we cross multiply

n+3=8*(-2)

n+3= -16

n= -16 - 3

n= -19

lets check if we are correct

8=-19+3/-2

8= -16/-2

-16/-2=8

4) 9=x/2+6

we first calculate the fraction

x/2+6

L. c. m is 2

x/2+6/1=4x + 8/2=12x/2

2 times 2=4 plus x = 4x

2 times 1 =2 plus 6= 8

thats how i got 4x + 8/2

back to the question

9=12x/2

cross multiply

12x=9*2

12x=18

x=18/12

we will use 2 to divide it

9/2

3 will divide

3/2

x=3/2

3. Are these ratios equivalent? 35:28 and 10:8 *

attashe74 [19]

Reduce each ratio to its minimum expression to find if they are equal.

35:28

$\begin{gathered} \frac{35}{28}=\frac{7\cdot5}{7\cdot4} \\ =\frac{5}{4} \end{gathered}$

10:8

$\begin{gathered} \frac{10}{8}=\frac{2\cdot5}{2\cdot4} \\ =\frac{5}{4} \end{gathered}$

Since both ratios reduce to 5:4, they are equivalent.

Another way to check a:b is equivalent to c:d, is that a*d = b*c

In this case, this will be true if 35 times 8 is equal to 10 times 28:

$\begin{gathered} 35\cdot8=280 \\ 10\cdot28=280 \end{gathered}$

Since both products are equal, then the ratios are equivalent.

Find the volume of a rectangular pyramid

Nesterboy [21]

Answer:

192 yd³

Step-by-step explanation:

The volume of a rectangular pyramid is given by the formula:

$V=\frac{1}{3} lwh\text{ where } l \text{ is the base length, }w \text{ is the base width, and }h \text{ is the pyramid height}$

In this case: $l = 9, w=8, h = 8$

$\therefore V=\frac{1}{3}(9\text{ yd})(8\text{ yd})(8\text{ yd})=192\text{ yd}^3$
