What value makes 3(a+1.5)= -1.5 true

1 answer:

3 0

First, write the equation:
3(a+1.5) = -1.5
Next, you can distribute 3 into the parentheses by multiplying 3 by a and 1.5. It should look like this:
3a + 4.5 = -1.5
When trying to find the value of a variable, you want to get the variable to one side of the equation by itself. Subtract 4.5 from both sides of the equation to get:
3a = -6
Now, divide both sides by 3 to get your final answer:
a= -2
The value that makes the equation true is -2
Hope this helped!

3x + 4y = 12<br> x + 2y = 10

borishaifa [10]

Answer:

x=-8 and y=9

Step-by-step explanation:

rewrite the equations to x+2y=10,3x+4y=12

sub 2y from both sides x+2y-2y=10-2y

substitue x=10-2y in 3x +4y=12

3(-2y+10)+4y=12

distribute

add-30 to both sides

divide both sides by -2

y=9

sustitute 9 for y in -2y+10=x

x=-8

Solve the following factorize and the en- equation of quadrate equation X² + 5x + 7 x = 0

nlexa [21]

Answer:

{-12,0}

Step-by-step explanation:

first to solve this can collect like terms and add

X² +12x=0

and solve it by factorization method

X² +12x=0

x(x+12)=0

it means x multiplied by x = X² then x multiplied by 12 = 12x

so this means x or (x+12) equals to zero

x=0 and (x+12)=0

x+12=0

x=-12

so the solution set is {-12,0}

but can also be done by formula method

You are planning a new production floor. You will need space for eight manufacturing processes and six stockpiles. Each takes 16

mina [271]

Answer:

Total space needed is 3136 square feet.

Step-by-step explanation:

We are given the following in the question:

Space required for eight manufacturing processes and six stockpiles.

Each takes 160 square feet.

Space required for 8 process =

$=8\times 160\\=1280\text{ square feet}$

Space required for 6 stockpiles =

$=6\times 160\\=960\text{ square feet}$

Total space =

$=1280 + 960\\=2240\text{ square feet}$

Open space required = 40%

$=\dfrac{40}{100}\times 2240\\\\=896\text{ square feet}$

Total space required =

$=2240 + 896\\=3136\text{ square feet}$

Thus, total space needed is 3136 square feet.
