Solve for X, will mark as brainliest! 6(1+x)+x=-14

Nutka1998 [239]

Answer:

X is equal to -10

Step-by-step explanation:

#1. Multiply 6 to (1+x). Doing this makes this equation: 6+6x+x=-14

#2. Then add 6x and x to get: 7x+6=-14

#3. Then move 6 to other side of equation, while at the same time, changing it's absolute value: 7x=-14-6

#4. now you have: 7x=-20, now just divide 7 by -20 WooHoo! You finished it! you have: -2.85714285714 or 2 and 43/50.

If the volume of each case is 1,000 cubic inches, could she use a table with a top that measures 212 feet long and 112 feet wide

Answer:

You could not use a table with a top that is 2 1/2 feet long and 1 1/2 feet wide

Step-by-step explanation:

The complete question is

Elena needs to find a table that will fit three cube-shaped cases, each containing a frog.If the volume of each case is 1,000 cubic inches, could she use a table with a top that measures 2 1/2 feet long and 1 1/2 feet wide?Explain

step 1

Find the length side of the cube-shaped case

we know that

The volume of the cube is equal to

$V=b^3$

where

b is the length side of the cube

we have

$V=1,000\ in^3$

substitute

$1,000=b^3$

solve for b

$b=10\ in$

step 2

Convert feet to inches

$1\ ft=12\ in$

we have

$2\frac{1}{2}\ ft=2.5 (12)=30\ in$

$1\frac{1}{2}\ ft=1.5 (12)=18\ in$

step 3

Compare the dimensions of the table with the dimensions of the cube-shaped case

30 > 10

The length of the table is greater than the length side of the cube

18> 10

The width of the table is greater than the length side of the cube

therefore

You could not use a table with a top that is 2 1/2 feet long and 1 1/2 feet wide

Circle Y has an area of 394.38cm ^ 2 . What is the circumference? Use 3.14 for pi Round to the nearest hundredth.

Oduvanchick [21]

Answer:

70.38 cm

Step-by-step explanation:

π = 3.14

Area of a circle = πr^2

394.38 = πr^2

125.598726 = r^2

r = 11.2070837 cm

Circumference = 2πr

C = 70.3804856 cm
