2 + 3( 4x + 5) = -53
Answer:
x=-35/6
Step-by-step explanation:
2 + 3( 4x + 5) = -53
subtract 2 from both sides= 3(4x+5)=-55
divide both sides by 3 = 4x+5=-55/3
subtract both sides by 5 = 4x=-70/3
divide both sides by 4 = x=-35/6
x=-35/6 is your final answer
Answer:
Hope this helps :)
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
x=−35/6
Decimal Form:
x=−5.8¯3 (Repeating)
Mixed Number Form:
x=−5 5/6

What slope is perpendicular to:
m = 5/8
The slope that is perpendicular to m = 5/8 is given by; m' = -8/5
When dealing with slope - intercept form of equation of a line, the general equation is;y = mx + c
where;
m is the slope
c is the y-intercept
Now, for a line to be perpendicular to a line above that has it's slope as m, the slope of this new line will be the negative inverse of the first slope. This is; m' = -1/mApplying that to our question, it means the slope that is perpendicular to m = 5/8 is; m' = -1/(5/8) = -8/5Read more at; https://brainly.com/question/21441448

According to the U.S. Geological Survey, there are over 300,000,000 cubic miles of water on the planet. How this number represented in scientific notation
0 3 x 108
0 3 x 10°
30 x 108
0 30 x 10
Answer:
3 x 10^8
Step-by-step explanation:
300,000,000 in scientific notation is 3 x 10^8 and because it’s 8 zeros
The number 300,000,000 represented in scientific notation will be 3 × 10⁸. Then the correct option is A.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

factorsie x squared + 5x-14
Answer:
(x+7)(x-2)
Step-by-step explanation:
=x^2+5x-14
=x^2+(7-2)x-14
=x^2+7x-2x-14
=x(x+7)-2(x+7)
=(x+7)(x-2)
Answer: (x+7)(x-2)
We're looking for two numbers that multiply to -14 and also add to 5. Through trial and error, you should find those numbers are 7 and -2.
You can use the FOIL rule to confirm that (x+7)(x-2) expands out to x^2+5x-14
(x+7)(x-2) = x^2-2x+7x-14 = x^2+5x-14

How do I solve for c
Answer:
Uhhh add the top then divide by bottom
Step-by-step explanation:
Bc yes
Answer:
[tex] c = \dfrac{3e + 3d - 5D}{2b} [/tex]
Step-by-step explanation:
[tex] \dfrac{2bc + 5D}{3} = e + d [/tex]
Multiply both sides by 3.
[tex] 2bc + 5D = 3(e + d) [/tex]
[tex] 2bc + 5D = 3e + 3d [/tex]
Subtract 5D from both sides.
[tex] 2bc = 3e + 3d - 5D [/tex]
Divide both sides by 2b.
[tex] c = \dfrac{3e + 3d - 5D}{2b} [/tex]

Answer:
There are 15.748 inches in 40cm. Can I please have brainlest?
Step-by-step explanation:
Answer:
40cm
Step-by-step explanation:
If you are converting 40cm to one inch and the conversion ratio is 2.54 : 1, you would place 40 in the numerator as the original ration has 2.54/1 as a fraction and the same will apply to 40cm.
** This applies if you are finding which number is in the numerator and not the answer to how much 40cm in inches is.
